Is it possible to install a gas boiler in the bathroom: norms and rules. Is it permissible to install a gas boiler in the bathroom and toilet?

Those people who are faced with issues of supplying gas to their home have to deal with various difficulties and obstacles from the gas service. The most important thing is that the legislation does not collect all the norms and requirements for equipping a boiler room in a private building in a separate document. Therefore, the country's gas producers can manipulate the requirements at their discretion, paying attention to some details and reducing their vigilance in other cases. But the basic requirements of gas workers in different regions are still largely similar. The requirements for a gas boiler room are aimed at complying with safety regulations for working with gas-powered heating appliances. They are aimed at minimizing losses from gas leaks and explosions.

Why do you need a heating boiler in the bathroom?

Very strict standards and regulations apply to gas-using equipment.
They describe literally every installation step and every square meter required to obtain permission to put the device into operation. It is most logical to install a gas boiler in the boiler room, but not every owner of a house or apartment can afford to allocate extra square footage. Therefore, it most often takes its place in the kitchen.

But now there is a fashion for stylish modular sets, into the design of which boilers do not fit well. In addition, due to the savings of all the same square meters, not everyone can afford a separate dining room for a noisy feast, and again, the boiler can prevent active gatherings with friends.

In studio-type apartments, the installation of gas-using equipment is prohibited, since the kitchen area communicates with the living area. The only possibility of gasifying such a room would be to install equipment in the bathroom, but this option is prohibited by current legislation

And you never know why the owner’s kitchen is not suitable for installing boilers in it. Maybe it’s a lack of square meters, a studio apartment, fear of a fire or the fact that a small child will fit into the appliance when sharing a cooking space, and so on.

The bottom line is that, in fact, many people want to use the bathroom as a boiler room.

Is it possible to install gas equipment in the bathroom and toilet?

Quite recently, to the question of whether it is possible to install a gas boiler in a bathroom, the answer was unequivocal, and, as they say, was not subject to discussion - “no, it’s impossible.” Until 2002, while the previous standard was in force, it was impossible to install a gas boiler in the bathroom. The document did not stipulate any exceptions or possibilities in which such an installation would be possible; there was simply a ban.

The new documents SNiP SNiP 31-02-2001 and 42-01-2002 “Gas distribution systems” have not added clarity; there are instructions that it cannot be installed in places of increased danger, and that it is forbidden to lay gas supply pipes through ventilation shafts, but directly, It’s never said that you can’t place a boiler or water heater in a bathroom or toilet.

This state of affairs allows us to have a certain freedom of action, since if we are guided by the principle “everything that is not prohibited is permitted,” theoretically this can be achieved, even on official grounds.

Installation Features

If the design of the water heater does not fit into the interior of the bathroom, the thought arises - how to hide it. But the requirements prohibit closing gas equipment, because this disrupts ventilation, which can lead to extinguishing the wick.

But if you approach the matter wisely, you can find a way out of the situation. For example, build a plasterboard niche or cabinet yourself. Follow these rules:

The niche should be significantly larger than the body of the device;
Equipment control systems must be accessible so that, if necessary, inspection or repair can be carried out without difficulty;
The heater should not make it difficult to move around the room.

Notice how some users approached the problem:

Installation and connection steps:

Markings are made on the wall in accordance with the measurements;
Using a drill or hammer drill, holes are made for installing fasteners;
The body is hung on anchors or dowels;
A pipe is attached to the nozzle to remove combustion products. Its other end is attached to the chimney opening. When using corrugations, the connection points are secured with clamps. Consider heat resistance when choosing a material (it must withstand at least 200 degrees). If you are using a steel structure, seal all cracks with sealant;
The water supply is carried out using metal-plastic pipes. Flexible hoses up to 2.5 meters long are connected to the body;
Connection to the gas main is carried out by specialists; they must have an official work permit. A yellow shut-off valve is installed in that place.

What can be concluded? If you use common sense, it becomes clear that the bathroom of an ordinary apartment cannot correspond to a volume of 15 m³. There is no window or normal ventilation. It makes more sense to hang appliances in the kitchen. But if you have a large bathroom, then such an installation is possible. The main thing is to adhere to the standards.

Show or hide

Of course, we all want to make the bathroom the most comfortable and aesthetically pleasing room possible, because this is a territory not only of hygiene, but also of relaxation. Large-sized gas equipment that is not always attractive in appearance usually does not fit into our ideas of a beautiful and comfortable bathroom, although now you can find speakers on sale that can become a decoration for the bathroom.

It would seem that the most obvious solution is to hide the gas water heater inside the wall, but all standards and safety requirements strictly prohibit this. Therefore, if you do not want to leave your instantaneous water heater in plain sight, you can hide it in a plasterboard niche or in a closet.

What do you need to know when installing a gas boiler in a bathroom?

To determine whether it is possible to place a gas boiler in the bathroom, you will have to carefully study the current building codes and regulations and evaluate the existing premises. Here it is recommended to first decide for yourself whether a gas boiler is needed in the bathroom at all. Traditionally, in private houses or cottages there is a special room for such devices, equipped with forced ventilation and meeting all the conditions for furnace and boiler rooms. The location of the boiler in the bathroom is a somewhat non-standard option, although in Soviet times it was allowed to combine a bathroom and a furnace in low-rise buildings in the private sector. But this was most likely an exception, and in the future, when replacing old gas equipment with new appliances, gas workers usually refused permission to install a gas boiler in the same place in the bathroom. Today, if you are guided by existing standards and fulfill all the technical conditions for this premises, it is quite possible.

The second no less important point that you will have to take into account is the requirements of gas equipment manufacturers for the installation site. The bathroom, even if all the nuances of ventilation and size are observed, will still be a room with high humidity. And high humidity, as we know, is one of the reasons why service centers will quite reasonably remove the device even with a partial warranty. Alas, control boards for gas appliances remain very sensitive to high humidity.

How to repair a bathtub with a geyser

From the very beginning, you need to think about the fact that if the water heater is old, it is best to replace it with a new, more modern, powerful and safe one, so that in the future you will not have to repair the gas appliance. Further, owners must understand that it is not always possible to move and transfer a gas water heater from one wall to another, which is due to the restrictions established in SNiPs for the safe use of gas equipment. However, despite such seemingly harsh conditions, if you approach the renovation issue correctly, the resulting bathroom will become beautiful, comfortable and practical.

Stages of renovation work in the bathroom:

Calling a designer to decide on the type of repair, style direction, and use of certain finishing materials
Drawing up a project and estimate
Purchase of necessary construction and finishing materials and mixtures
Dismantling old plumbing fixtures, disconnecting and removing the gas water heater, leveling the walls, ceiling and floor
Replacement of water and sewer pipes
Laying flooring, tiling walls, making plasterboard, suspended or slatted ceilings
Installation and connection of a new gas water heater (or an old one, if it is serviceable and operational).

You should understand that renovating a bathroom with a geyser is not an easy job, which should only be trusted to qualified craftsmen. The specialists of the Master Sanuzlov organization will be able to quickly and comprehensively complete the task, taking on all the work. Everything is done on a turnkey basis, delivered within a strictly specified time frame, and our craftsmen always remove all construction waste after themselves.

A gas water heater often complicates the arrangement of a kitchen, because it takes up so much space, almost always has an inconvenient location, spoils the appearance of the wall, and even requires careful handling. In this material we will tell you what can be done with this useful, but difficult device, and how to plan the renovation and design of a kitchen with a gas water heater without compromising storage reserves, the beauty of the interior, your wallet and safety. And here you will find a selection of 40 photos of interiors, from which you can get a lot of useful ideas.

Basic conditions for placing a gas boiler in a private house

So, to understand the problem of whether it is possible to install a gas boiler in a bathroom, you need to compare the provisions of several regulations.

Current building codes do not directly prohibit the installation of such equipment indoors, but at the same time require that the following requirements be met:

The total area of the room must be at least 9 square meters;
The room must have natural ventilation;
The boiler power should be no more than 35 kW;
There should be no high humidity in the room.

Regarding the total area of the room, you need to remember that for a closed combustion chamber the area allowed is 8 square meters, and for an open burner 9 are required.

For boiler rooms and rooms where heating equipment is located, a ventilation system is required. The only catch is that ventilation must be natural, in which air circulation is carried out continuously, without the participation of special instruments and devices. The bathroom is usually equipped with a good ventilation system, but often this system is enhanced by additional equipment - an exhaust or supply fan. From a hygiene point of view, this is good, but from a gas equipment safety point of view, this will be a violation of the technical operating conditions of gas installations.

For private houses, it is allowed to install a heating boiler with a power of up to 35 kW in the kitchen or other room. More powerful heating systems require placement of devices in separate rooms, and this room must meet the requirements of mini boiler rooms, but not a bathroom.

And of course the issue of humidity. The conditions for laying gas supply pipelines must ensure the integrity of the pipes and protect them from corrosion, which means that in a bathroom, as in a room where there is high humidity, metal pipes will be subject to corrosion. So when planning the placement of equipment, the bathroom option will most likely be rejected.

Regulatory documents

You are unlikely to find a clear answer to the question of whether it is possible to install a gas unit in a bathroom in the documentation. According to SNiP standards of 1987, the placement of such equipment in the bathroom is prohibited. However, later, since 2003, the cited SNiP was declared invalid and instead SNiP 42-01-2002 “Gas distribution systems” was put into effect. But it does not clearly indicate whether a gas boiler can be installed in a bathroom. You can only get an affirmative answer by contacting your gas supply company.

Important! Only a device with a closed, hinged combustion chamber can be installed in a bathroom or toilet.

As practice shows, most gas workers prohibit the installation of gas equipment in the bathroom. The main reasons for refusal are the following:

It’s easier for those who already had a gas boiler in their bathroom or toilet. Then they replace the old unit with a new one without much paperwork.

However, some owners resort to tricks and, in order to obtain permission from the gas service, pass off the future bathroom as a furnace room. And after installing the unit, a shower and sink are also placed there. But such a violation is fraught with negative consequences in the form of fines and disconnection from the gas main. The fact is that gas workers are required to periodically check the gas equipment located in the house, so in a year or two the fraud will still be discovered and you will have to pay dearly for it.

If, despite the refusal, you are ready to continue to seek permission to install the unit in the bathroom, then you can go the following way:

Find out here which gas boiler is best for heating - selection criteria and manufacturers

What could it be like to install a gas boiler in a bathroom?

Despite the fact that there is no direct ban on placing a gas heating boiler or water heater in the bathroom, gas workers are reluctant to issue technical specifications for such projects. Most often, they themselves offer not entirely honest schemes, according to which this room was originally intended for the installation of a gas boiler, but then somehow it changed its purpose. This option may indeed work for some time, but at the first check, it turns out that a redevelopment was made that was not agreed with the project and the household will be automatically disconnected from gas supply as not meeting safety requirements with all the ensuing consequences - a fine, reworking of the project, organization new equipment connection.

It's another matter when the project is actually agreed upon with the gas company and officially approved. In this case, you will have to do everything as required by the documents - not only to ensure a sufficient area of the premises, but also to comply with all the recommendations of the gas workers. For example, in order to avoid any problems, you will have to install a window in the room, make ventilation holes in the door, and lay a separate ventilation pipeline leading to the roof. Only in this case is it possible to obtain permission to install a boiler in the bathroom.

Use of liquefied gas

“Problems” with project documentation are not required in the case of using not natural, but liquefied “ballooned” gas. However, in this case the column must have an appropriate design - burners for natural and liquefied gas have different diameters of injector nozzles. Although such equipment is produced by many manufacturers, it is quite rare on sale and is demanding in terms of gas quality.

In any case, the wall where the speaker is installed must be strong and non-flammable - if it is made of plasterboard, then a “mortgage” for attaching the heater, made of wood or metal, must be mounted in it in advance.

Pros and cons of installing a gas boiler in the bathroom

In order to evaluate the possibility of equipping a bathroom with a gas boiler, it is worth, among other things, studying all the positive aspects of this project. In a private house, especially if the premises are being redeveloped, the problem of placing new equipment is always very acute. That is why the option of using a heating boiler and a bathtub together in the bathroom is quite ambitious and has a number of advantages:

The space inside the house is significantly saved;
The number of pipelines is reduced;
Hot water enters the bath faster, there is no large temperature loss;
In other rooms there is no noise from operating equipment;
A window will appear in the bathroom.

On the other hand, this arrangement also has a number of disadvantages that must be taken into account:

The bathroom will have to be equipped with a separate ventilation system and constantly maintained in good condition;
High humidity has a negative effect on equipment, especially electronic components;
In the bathroom, in addition to the water supply pipes, additional heating pipes will be added, and this will take up a little more space.

Installation features

Installation and adjustment of gas boilers

If you choose from all types of gas devices, then the most acceptable option for an apartment is a wall-mounted double-circuit boiler. With its help you can provide heat in the room and hot water for domestic needs. And placing it on the wall will significantly save usable space.

If in private houses you can even choose a separate room for a heating unit, then for a city apartment the most acceptable option is a kitchen, which already has a gas stove, cold water supply and, as a rule, reliable ventilation. Therefore, installing gas heating in the kitchen is the best solution for a small city apartment.

Modern double-circuit type products include a circulation pump, the operation of which requires a constant supply of electric current. In the event of an emergency with electricity supply, a backup power source in the form of a power plant is installed in country houses.

Important! This cannot be allowed in an apartment, so for emergency connection you can use an uninterruptible power supply, like for a computer, only more powerful. It will last for several hours of operation until the emergency on electrical networks is eliminated.

For normal operation of a gas boiler, an expansion tank is also required, which must constantly contain water for the heating system. When heated, water or another type of coolant expands, and its excess enters this container, and when cooled, it goes back into the system. That is, the principle of operation of the expansion tank is the same as for the car cooling system.

Installation of gas boilers is strictly prohibited in the following cases:

installing devices near flammable objects
in the hallway and bathroom due to increased humidity and reduced fresh air supply
in dormitories
in the basement and on the balcony
in the basement, which is located below ground level
in rooms not equipped with windows

Regarding the basement floor, installation of gas equipment is allowed if there is special permission from the regulatory authorities.

Installation of gas stoves in bathrooms

According to the documentation on working with heating systems, in the section on residential multi-storey buildings there are no clear prohibitions on the installation of this type of equipment.

Thus, a gas water heater in the bathroom is a completely suitable way to heat water.

Geyser on the wall in the bathroom

However, according to accepted state requirements, it is necessary to take into account many nuances when choosing a gas unit and when installing such a design. It is necessary to take into account the specific layout of the bathroom.

Certain provisions of the Code of Norms and Rules dated January 31, 2003 provide for the installation of gas equipment with a closed chamber type in multi-apartment buildings in the absence of such buildings being connected to a central or individual heat supply system .

At the same time, heat sources and water heaters using natural fuel are allowed to be connected in some rooms. This is specified in paragraph 7.3.8. SNiP. In addition, the total thermal power of such devices, according to the rules, is no more than one hundred kilowatts.

Gas boiler diagram

It is allowed to install similar devices in kitchen units, the amount of energy converted should not exceed thirty-five kilowatts.

Such gas equipment can only be installed in premises of a certain type. According to official documents, the room must have a light opening. When calculating glazing, certain standards must be met. So, for one cubic meter of room there should be approximately 0.03 square meters of glass. It is also necessary to ensure effective ventilation.

The total volume of the room must be at least 15 m3. These parameters are related to the safety and comfort of using heaters and carrying out work on their installation. The height of the room is at least 220 cm. It is necessary that the passages in the room remain free. Their minimum size should reach seventy centimeters.

Additional installation conditions

It must be remembered that placing gas appliances in the basements of apartment buildings is prohibited. When installing, you must follow the following rules from clause 7.3.8:

Gas units and heat generators are mounted on walls made of non-flammable or low-flammable materials .
The installation must be carried out so that the gaps between the device and the wall are at least 3 cm .
The finishing of walls near the heat generator must be made of fireproof materials .
The facing coating must extend beyond the unit body by no less than 10 cm .
For floor-standing equipment, additional fire safety measures must be taken. The floor surface where the heat generator is installed should be covered with special non-flammable materials . This area must be arranged so that it extends beyond the body of the gas appliance by at least 10 cm.

The official regulatory document on heating, ventilation devices and air conditioning 41 – 01–2003 in the section on heat supply systems provides rules for the installation and operation of gas appliances, as well as technical conditions for rooms where such equipment is connected.

Gas water heater

In residential multi-storey buildings and various outbuildings, it is necessary to install heat generators with a sealed combustion chamber and automatic safety devices. Such devices stop the flow of gas when the power suddenly goes out, the protection circuits break down, when the burner malfunctions or when the pressure in the coolant decreases significantly. Sometimes an automatic emergency shutdown is necessary when there is poor smoke removal or other equipment malfunctions.

According to existing standards, units whose power does not exceed thirty-five kilowatts are allowed to be installed in the kitchen or hallway.

Gas heating equipment in the kitchen

Appliances with heating output exceeding the specified norm must be installed in separate extensions. The total power of such equipment should not exceed one hundred kilowatts according to the standards.

The supply of oxygen for combustion processes must occur through the air duct. It must be placed on the street side for equipment with a sealed chamber. And for open-type heat generators, air is taken from the very room in which the installation was carried out. These requirements are listed in paragraph 6.2.4 of SNiP.

Provision 6.2.5 of this document states that the chimney must be positioned vertically. In this case, it is not allowed to reduce the cross-section of the smoke exhaust pipe. It cannot be laid in residential premises.

In the room where the heat generator with a sealed combustion chamber is located, it is necessary to equip general exchange ventilation, the calculation of which should be at least 1 exchange per hour.

When installing devices with an open combustion chamber, it is necessary to take into account the air flow for fuel combustion. The ventilation design prevents vacuum, which affects the removal of smoke from the heat generator.

Official rules for installing gas water heaters in the bathroom

In many respects, a bathroom water heater is a prohibited type of water heating equipment. Taking into account the conditions given in the official documentation of utility services, we can conclude that such instantaneous heaters are not intended for connection in the bathrooms of standard apartments.

Modern geysers

State standards require a room of at least 15 m³ in volume for the installation of gas equipment, and standard bathrooms are usually significantly smaller. To install the speaker, it is necessary to ensure good ventilation of the room. The minimum permissible area of a bathroom window according to the established standards should be 0.45 m². However, in most cases, the bathrooms of typical apartments do not have windows facing the street and there is no need to talk about high-quality ventilation of the room.

Therefore, bathrooms are not designed to use gas water heaters. Installation of such equipment is possible only if the premises are redeveloped in accordance with the requirements of the state gas service.

Is it possible to install a shower, toilet and washing machine in the boiler room?

Is it possible to install a gas boiler in the same room as a shower stall?
author: Sergey

Is it possible to install a shower stall in the same room with a double-circuit gas boiler in a private house, subject to all safety rules for operating gas equipment? If not, what is the reason for this?

Best regards, Victor Danilchenko

It will be better if the booth is installed at a distance of at least a meter from the boiler. This way the gas workers will be calm, and you will be safer. You can also make a partition between the boiler and the cabin. But in any case, you need to consult with gas workers.

Is it possible to install a shower stall in the same room as a gas boiler?

Good afternoon Please tell me, is it possible to install a shower stall in a room where a gas boiler is located?

Is it possible to install a shower, toilet and washing machine in the boiler room?

Hello. Tell me, is it possible to install a shower, toilet, and washing machine in a boiler room of 9 m2, 25 m3? Beretta boiler 24 kW, water heater 180 l?

Theoretically possible, practically difficult. There are many regulations governing the installation of gas equipment. These are SNiPs 41-01-2003, 2.04.08-87, 31-02-2001, 42-01-2002, SP 42-101-2003 and a number of departmental documents. Nowhere is there a direct prohibition on installing a gas heat generator in a combined bathroom, but this is what a room with a shower, washbasin and toilet should be called. You definitely cannot place the boiler only in living rooms. Allowed in kitchens and separate rooms not located in the basement and meeting SNiP standards.

The basic requirements for installing a boiler of the power you specified are:

The total volume of the room must be at least 7.5 m3 (for the kitchen 13.5 m3); Ceiling height from 2 meters; The presence of natural exhaust and inflow, providing three air exchanges within an hour; The room must have a window with a net glazing area of at least 0.8 m2 with a standard glass thickness of 4 mm. It is necessary to ensure that combustion products are removed from the boiler in accordance with building codes and manufacturer's requirements.

But there are additional requirements.

All heating equipment placed in a room with high humidity (namely, a shower room) must have an anti-corrosion design. Let's say you convinced the relevant authorities of this. Let's say the passports of your boiler, pump and voltage stabilizer indicate that the electrical equipment has an increased class of protection against moisture, not lower than IP 44 . Let's say you managed to maintain all the necessary distances from plumbing to heat-generating appliances, this is at least 60 cm. There is still the problem of electrical outlets: according to existing standards, there should not be any in the bathroom. You can connect the devices directly or install special waterproof sockets, and route the wiring through sealed cuffs . Theoretically, if these conditions are met, it is allowed to combine a furnace room and a bathroom. Although, from a technical point of view, this is really not the best solution. In addition to the boiler itself, you will also have to install a boiler, pumping group, pipelines and other equipment. Will it be possible to rationally place all this in the bathroom?

In practice, the decision depends on how your local gas authorities interpret the concept of “separate room” . From the point of view of construction terminology, this is any room separated by a door from the common space. From the point of view of gas workers, this is a room intended only for the installation of heating equipment. They are calm about placing a washbasin in the furnace room, they rarely object to a washing machine, but, as a rule, they are categorically against the presence of a shower, bath, steam room, or complex electrical equipment in the boiler room. In addition, gas service specialists are right: from a technical point of view, this is really not the best solution. Domestic standards directly allow the placement of a gas boiler in the kitchen. This may be the best solution for you. Again, theoretically, one can argue with this approach. There are rare cases where developers managed to implement such a solution, proving that there are no direct prohibitions on installing a gas boiler in the bathroom. However, if you are not ready to get involved in long disputes, bother with additional documents, coordinate technical details and their implementation with biased inspectors of gas, fire and energy services, we advise you to think about an alternative solution. You can get more detailed information first-hand from your regional gas service.

Gas workers appeal only with fears for our lives in the event of a gas leak, and they do not have any SNiPs about the placement of shower cabins in furnace rooms.

9.32 The installation of water heaters, heating boilers and heating devices should be provided in kitchens and furnaces that meet the requirements of 9.37 and 9.38. Installation of these devices in bathrooms is not allowed .

And yet, according to our passport, this room is not a bathroom, but a furnace room, which meets the requirements of 9.37 and 9.38. So, nowhere in these requirements is there a ban on installing showers, toilets and sinks in furnace rooms. Or am I not right?

That is, if a gas boiler is made “of anti-corrosion materials or with protective coatings against corrosion,” then it can even be installed in a bathroom? I’ll try to “fight” with the designers.

List of necessary actions

If it becomes known that the installation of individual heating is allowed in the house, a long visit to the authorities cannot be avoided:

First of all, you need to go to the local organization responsible for gas supply and write a statement there regarding the installation of a gas boiler in the apartment. After a certain time, the home owner is given a conclusion regarding permission or prohibition to install the heating unit. Receiving a positive response means that the equipment can be installed.
Next you will need a project. It should be ordered from a design office that has the right to carry out this type of work. Its address can be obtained from the gas supply company. At this stage, it is advisable to select a boiler model and meter. Design documentation must be drawn up for them, and the data must be indicated in the specification. The fact is that changes after approval can only be made later, and for a fee. If the project is signed, nothing can be changed in it; you need to order a new one.
The fire inspection authorities should find out the address and name of the organization that checks the condition of ventilation ducts and agree with its specialists about the service. A company representative will come and check the quality of ventilation. If everything is in order, permission will be issued to install a gas boiler in the apartment. In case of unsatisfactory condition of the chimney, a report is drawn up with a list of work that should be performed. After eliminating the deficiencies, you need to re-invite a specialist in order to ultimately obtain permission.
At the next stage, an application to refuse heating is submitted to the heating network. If you plan to heat the water yourself, you should also refuse hot water supply. It is advisable to immediately clarify the timing of the shutdown measures. You should already have a remodeling project approved by Gorgaz on hand.
Data regarding the purchased meter and boiler are reported to the design organization. Then the completed documentation is collected. It is not worth purchasing equipment in advance, since permission to install a gas boiler in an apartment building cannot always be obtained.
Then, at the Gorgaz branch, a contract for servicing the unit is concluded, and the gasification project is submitted for approval.
After receiving the signed project, you can begin to disconnect from the heating network. In this case, you will need to drain the water from the heating system of the entire house.
Next, the apartment owner must install an individual heating system. The boiler is installed without connecting to the gas main, the system is checked for leaks and readiness for operation.
Gorgaz is finding out the date when a gas boiler can be installed in an apartment building in a specific apartment. Its employees will connect pipes and equipment according to the project, seal the meter, and put the stove and unit into operation.
In order for the guarantee for a gas boiler to be valid, adjustment and first start-up will be required, followed by a mark in the passport. Regarding this type of work, you should contact the department where the device was delivered for service. The technician will adjust the boiler, start the system and put a stamp in the passport. Now you can use the installed equipment.

The entire process described above, in compliance with the requirements for installing a gas boiler in an apartment building, will take from 1.5 to 2.5 months. Therefore, it is advisable to start the procedure in spring or at the very beginning of summer.

Installation features

Knowing all the requirements for a gas water heater, you need to familiarize yourself with a number of rules that apply to the installation of equipment.

Installation and connection of the gas water heater must be carried out by licensed specialists.

Plumber specialist

The geyser installation process includes the following steps:

Initially, it is necessary to install an asbestos pipe. To do this, you need to make a corresponding hole in the ceiling or wall. The length of the asbestos pipe should be approximately 1500 mm. Then we proceed to install the device itself. The gas water heater must have mounting holes according to which markings are made on the wall

In this case, it is very important to use a level, otherwise it will not be possible to install the device level. The equipment is secured using special dowels with hooks. Under them you need to drill holes in the wall that will be identical in diameter. After the geyser is installed, a corrugated pipe must be laid from the device to the chimney to remove combustion products. Then you need to connect the water heater to gas. At the next stage, the connection to the water supply is made, and cold and hot water must be supplied to the gas water heater. The last thing you need to do is install a filter, which can be magnetic or saline.

What requirements must a bathroom meet?

It is important to understand that not every bathroom is suitable for installing a gas boiler. For example, standard bathrooms in ordinary Khrushchev or 9-story buildings built in the 70s and 80s are too small and do not have sufficient ventilation. In order for it to make sense to even consider the possibility of installing a gas boiler in the bathroom, it must meet certain requirements:

total area of at least 7.5 m²;
the presence of a working ventilation system;
there must be a window with an area of at least 0.25 m²;
ceiling height not lower than 2 m;
when the door is closed, there should be a gap of 1-2 cm between it and the floor;
there should be nothing in front of the unit at a distance of 1 m;
Bathroom walls must be made of non-combustible materials.

Thus, from the above requirements it is clear that apartment owners in multi-storey buildings are practically deprived of the opportunity to install a gas boiler in the bathroom. The owners of private houses have a better chance, since they can initially build a bathroom that meets all the given standards.

Kitchen

The height of the room where the heating unit and cooking stove are installed must be at least 2.5 meters.

The room volume indicators vary within 15 cubic meters + 0.2 cubic meters, which are calculated for each kilowatt of gas boiler power, > 60 kW.

situation in the gas boiler room

requirements for a gas boiler room

The room must have sufficient ventilation. This includes the gas chimney and vents.

The kitchen should have a fairly wide window with a window opening outwards. The glazing area is three hundredths of a square per cubic meter of room volume. For a room occupying a volume of 16 cubic meters. m, windows should be 0.48 sq. meters. That is, in such a room, a window with dimensions of 0.5 m in width and 1 meter in height is acceptable (do not forget about the window opening outward).

A thin metal sheet or foil should be attached to the ceiling above the installed gas stove.

There should be a sufficient gap or additional ventilation at the bottom of the door.

The requirements for a gas boiler room located in the kitchen are not much different from the conditions in other isolated rooms of the house without a stove. Additionally, it should be taken into account that placement in a separate room provides for the separation of the boiler room from adjacent rooms by walls with the required fire resistance limit (not

What heating devices cannot be installed in bathrooms?

According to current legislation, types of equipment prohibited for installation in such premises include gas units, that is, boilers, heaters, convectors.

That is why, when a person asks a representative of the relevant service whether it is possible to install a gas boiler in the bathroom of a private house, he often receives a negative answer.

According to state regulations and standards, devices of this kind are not intended for use in closed premises.

It is also prohibited to use heating devices that run on gas and are equipped with open combustion chambers where forced ventilation is installed.

Despite the fact that such devices require good air exchange for proper operation, their installation cannot be combined with similar equipment.

Under such conditions, the combustion process is disrupted, combustion products begin to accumulate, and there is a danger of poisoning with harmful substances. Find out how to properly install a chimney.

Conclusion

When arranging your boiler room, it is best to consult with a knowledgeable gas service specialist in your region. Because, as inspectors checking the installation of heating equipment, they can find any reason to draw up an order with aggravating conditions or a fine. It is better to comply with all instructions from gas workers and similar services in advance. You can get acquainted with the opinions of your neighbors on equipping a room with a boiler, and get acquainted with information on the Internet. Then you will never pay extra money to representatives of the gas or chimney and ventilation services for servicing chimneys and other “inventions” of enterprising workers of such services. If there are no conditions for installing floor-standing boilers, it is better to install wall-mounted boilers that do not require such stringent requirements regarding the premises. However, when installing suspended structures, special conditions are imposed on the distribution pipeline system, couplings and adapters.

Boiler installation requirements

It is important to know that in order to install a gas boiler in the heating system, the premises must only be non-residential

This is worth paying special attention to. People ask whether it is possible to install a gas boiler, for example, in the kitchen or in a bathhouse or bathroom

Experts say that this can be done, but you will have to make a device that will help remove all the products that occur during the combustion process. Installation of gas heating boilers in such premises depends on how the chimney is installed. The latter should not interfere with the doors, and also comply with fire safety.

Boiler installation requirements

In the room where the boiler is located, you need to install a special system in which the ventilation will be of a flow type.

There is a hole under the ceiling through which air should escape, and above the table there is also a hole for entry. The height of these holes cannot be more than 30 cm, the height of the wall cannot be less than 2 meters, and the width cannot be less than a meter. If it is, and its area is small, then you can buy a low-power boiler, about 30 kilowatts. To install this boiler and connect the heating system to it, you need a room with a volume of 7.5 cubic meters. If the boiler is placed in the kitchen, it should be 12 square meters in area.

How to install a boiler in a bathroom.

Installing a boiler in a bathroom is a rather complex professional procedure that can only be done by qualified specialists in the field of design, installation, installation and maintenance of autonomous home heating . Craftsmen installing a gas boiler and accompanying heating equipment must have SRO approval and confirmed qualifications. Try not to install a gas boiler in the bathroom yourself, as this is illegal and can cause harm not only to your property, but also to the life and health of your household. To install a diesel boiler for heating a home , no special permission is required from government authorities, but in any case, amateur activity is obviously contraindicated here.

Most often, a chimneyless gas boiler is installed in the bathroom, as in a room not suitable for heating equipment. Such boilers are small in size and do not require a source of electrical energy. You can install a chimneyless boiler in any non-residential area of the house, including the bathroom; it is wall-mounted, but remember that such a boiler can only be attached to an external wall.

If the bathroom is large in area and volume and it is possible to install a chimney, then you can install a wall-mounted or floor-mounted gas boiler. Remember that there are a number of SNiP requirements for the size of the room in which the gas boiler is installed, the size of the doorway into it, the presence of ventilation, and much more. These requirements are well known only to qualified specialists who have extensive experience in the installation and installation of gas equipment in a private, country house.

Types of equipment

There are two types of boilers:

storage water heater;
flow boiler.

Storage type equipment is a boiler that is similar to a boiler. The device is equipped with a reservoir of various capacities. Storage elements are placed inside the tank. As hot water is consumed from the tank, the tank is filled with tap water. The automatic control panel allows you to regulate the heating temperature, prevents overheating and boiling of the liquid in the tank. Such boilers are produced in two modifications:

hanging - they are mounted on the wall;
stationary - installed on the floor.

A flow-through boiler has a more complex design. The column heats up quickly thanks to the heat exchanger. The liquid will become hot in 7-10 minutes. The main advantages of flow-through boilers:

efficiency;
ease of operation;
reliability of the unit.

In addition, such devices have an automatic ignition system. This guarantees the safety of using the equipment - gas vapors are burned in full.

As practice shows, flow-type boilers are more popular. The device has small parameters, it is convenient to place it in small rooms. At the same time, the boiler’s power is enough for a family of 5 people.

Is it possible or not to install a boiler in the toilet?

This cannot be done without officially certified permits. But under certain conditions, consumers manage to obtain permission to install gas units. If you also want to find out whether it is possible to install a toilet in the boiler room, or, on the contrary, a gas boiler in the toilet, then consider the following requirements:

Redevelopment of the premises, making adjustments to technical documents. If the gas service does not allow you to register heating equipment, you can take a risk and try to change the status of the premises itself. For example, turn a bathroom into a change room or storage room, submit a corresponding application to the BTI, thereby easily solving the problem. If you indicate these types of premises in the registration certificate of an apartment or house, then they will not be able to refuse you. But the presence of plumbing can lead to problems, namely a ban on installing the boiler.
Connecting a new device. If a heating device is already registered in the room design, then no one can prohibit you from installing a new device. The easiest way to replace the boiler is if you already have permission. Less often, craftsmen give consent to install water heating systems in bathrooms. The main thing is that these are devices equipped with a closed combustion chamber.

Boiler room in the utility room

Our citizens are not so rich and wasteful as to equip a separate room just for a boiler room. Therefore, they combine a boiler room with a sanitary unit with an installed washing machine, sink and bathtub, and toilet. Gas workers are “speaking out” against the toilet, demanding that it be fenced off with at least a plasterboard partition with a door. They are silent about the washing machine, probably because at the time when the standards were developed, there was no widespread installation of new-style washing equipment, and an ordinary washing machine was a portable item. Regarding the sink and bathtub, there are no special points in the requirements for a gas boiler room.

The boiler room must be 2.5 meters or more in height. Many owners had to sacrifice a storage room to convert the premises into a boiler room. But in this case, in the old storage room we had to enlarge the window, install a window, and drill holes at the bottom of the doors. In addition, ventilation had to be installed. If there were problems with the height of the room, then our enterprising owners, having read the requirements of the law that the height from the base of the heating boiler to the ceiling should be 2.5 meters, dug in the boiler to the missing 20-50 cm. In this case, the heating device was located in the pit and height requirements were met. Now in many areas gas workers are forced to bury such pits, agreeing with the existing height for the time being. In addition, old floor-standing boilers of huge sizes have been replaced by different types of heating devices of floor-mounted or wall-mounted installation. Some of them are very small in size, so you can solve the problem with the height of the room by changing the floor-mounted unit to a wall-mounted one. When installing it, a boiler room is not required.

Rules for installing gas appliances in an apartment

Owners of new apartments that are not connected to a centralized heating system have the least problems with arranging individual heating.

In this case, there is no need to visit the heating network and there is no need to disconnect from the risers, and permission to install gas heating in an apartment building may be included in the package of real estate documents.

But even in this case, you need to adhere to certain rules. First of all, having the documents in hand, you cannot install gas equipment yourself - this work must be performed by specialists. These can be not only employees of the gas supply organization, but also representatives of a company that has a license for this type of activity.

After installation is completed, an engineer from the company supplying gaseous fuel will check that the connection is correct and issue permission to use the boiler. Only then can you open the valve leading to the apartment.

Before starting, in accordance with the requirements for installing a boiler in an apartment building, the individual heating system must be checked. To do this, it is launched under a pressure of at least 1.8 atmospheres. This parameter can be controlled using the pressure gauge of the heating unit.

If the pipes are built into the floor or walls, it is advisable to increase the pressure and drive the coolant through them for at least 24 hours. Only after testing the system can you be sure that there are no leaks and that the connections are reliable.

Before starting, the equipment must be vented.

Since when installing a gas boiler in an apartment building the systems are made closed, you need to use Mayevsky taps available on the radiators.

Each battery is emptied of air, going around them several times in turn until there is no air left in them. After this, the system can be put into operating mode - turn on the heat supply.

An electrical outlet and other gas appliance must be placed at a distance of at least 30 centimeters from the unit.

Features of kitchen renovation and design with a gas water heater

When planning the design and renovation of a kitchen with a gas heater, you need to take into account fire safety rules, ventilation and ergonomic requirements. Here are some important tips to help you design your workspace in the best possible way.

If you are equipping a kitchen from scratch, then it is advisable to think about the location of the gas water heater, layout and interior design even before renovating and purchasing furniture. Then you will have more room for maneuver and fewer problems. For example, you can move the speaker, change it to a more modern model or one that suits the future environment, improve the ventilation and chimney at the same time, adjust the color scheme of the interior to match the speaker, etc.
It is advisable to purchase a kitchen set to order, regardless of whether you plan to build the water heater into a cabinet or not. This will allow you to arrange your headset without errors and use every centimeter to your advantage.
Is it possible to install a suspended ceiling in a kitchen with a gas water heater? It is possible if the height of the room with the sheet installed is at least 2.25 m, and there remains a distance of at least 8 cm from the chimney opening to the ceiling. In this case, it is advisable to equip the chimney not with an aluminum corrugated pipe, which gets very hot, but with a sandwich chimney with thermal insulation layer. This way, the ceiling will not be damaged by heat (from combustion products going into the chimney) and will not itself become an obstacle to draft. If necessary, the chimney opening can be lowered slightly.
The walls in a kitchen with a gas water heater should not be decorated with wallpaper or plastic panels (at least near the water heater), as these materials can deteriorate/melt under the influence of heat. Ideally, the walls should simply be plastered, painted or finished with ceramic tiles (see photo).

Small kitchen with geyser and walls lined with ceramic tiles

In a kitchen with a gas water heater, a constant flow of fresh air is required (50-90 cubic meters per hour). This is necessary both for your safety and for the combustion stability of the unit. Therefore, when installing plastic windows, choose those that have a micro-ventilation function, that is, special fittings that allow you to open windows with micro-slots from 3 to 7 mm. Both in winter and in summer, kitchen windows with a gas water heater should be opened in this mode. If wooden windows are planned or have already been installed in the kitchen, then due to their natural micro-slits the issue of passive ventilation will be resolved by itself. The main thing is not to overdo it with waterproofing, seals and window insulation.
Supply ventilation valves embedded in the wall, for example, Kiv-125 or KPV-125, will help ensure air flow even more effectively. It is advisable to take care of their installation before repairs, so as not to spoil the finish.
In a kitchen with a gas water heater, both the supply and exhaust systems must work in a balanced manner. Therefore, it is necessary to invite professional ventilation specialists to check the chimney and ventilation duct. If necessary, they need to be put in order. And, of course, when arranging your kitchen, do not make the most serious and, unfortunately, common mistake - do not cover the ventilation duct with plasterboard boxes, wallpaper, or furniture.
And the last piece of advice - “in any unclear situation,” consult the gas service and act in accordance with the requirements of regulatory documents.

Recommendations for installing gas equipment

First of all, it is recommended to carefully select the equipment for installation. For a bathroom, the best option is a double-circuit boiler with a closed combustion chamber. This type of equipment is best suited for small spaces. A wall-mounted boiler can be installed on an external wall, and gas exhaust and air intake are organized using one pipe, without large investments.

In order to separate the equipment from splashing water, it is recommended to fence off the boiler with a wall, this will ensure the safety of the boiler. When installing, comply with electrical safety requirements - the distance from the sink or bathtub must be at least 0.6 meters.

About installation rules

There are a number of requirements for installing gas equipment:

The vast majority of models need to be located in a separate room. The exception is wall-mounted units - they can be mounted in non-residential rooms, for example, in the kitchen or bathroom, if their size allows. Before installing the boiler, it is necessary to ensure the required ventilation in the boiler room.
The volume of premises for the installation of gas equipment with a closed chamber is not regulated, but the area must comply with the standards. In addition, the unit must have an outlet to the flue. It is unacceptable to bring it near the ventilation ducts.
Horizontally located parts of the gas duct cannot be more than 3 meters long and have more than three turns. The flue outlet must be raised above the roof level by at least a meter.
Wall-mounted models are mounted at a distance of 800 mm or more from the floor surface. No objects should be placed under the boiler, and a metal sheet must be laid on the floor. An expansion tank and an air valve must be installed.

Gas equipment cannot be installed in the following types of premises:

In the apartments of an apartment building without a main gas flue - these are the majority of old buildings.
In rooms with false ceilings and capital mezzanines.

It is almost impossible to install a floor model in an apartment in a multi-storey building. After all, this will require serious redevelopment with all the ensuing problems and costs. There are no restrictions on the installation of such equipment in a private home. Here it is better to make a separate boiler room, for example, in an extension. This room must meet the following standards:

Entrance doors are no narrower than 80 cm.
There must be a chimney that goes either to the roof or through the wall to the outside.
The height of the boiler room must be at least 2.2 m. The room is equipped with a ventilation system.

A double-circuit boiler with automation will require a separate branch of electrical wiring. An additional 20 A circuit breaker is installed on it. It is advisable to provide backup power to the automation, capable of maintaining its operation in normal mode at least for a day. To do this, you can purchase a diesel generator or a UPS - an uninterruptible power supply.

Severe demands are placed on the gas duct. Its minimum diameter is 110 mm, regardless of the power of the installed equipment. The optimal diameter of the gas duct is calculated based on the power characteristics of the unit - the higher the power, the larger the diameter.

Ways to get around the ban

Some particularly smart home owners are trying to circumvent this ban.

Even at the design stage, a spacious kitchen is provided in which gas equipment is installed and registered. And after commissioning, plasterboard partitions are installed and plumbing fixtures are installed in the resulting room.

Of course, this is done mainly in private houses; in apartment buildings, such redevelopment is most often technically impossible.

It’s good if the gas service is full of acquaintances who will turn a blind eye to the position of the boiler during the inspection, but most likely, on their first visit they will write you a report on the unacceptable placement of equipment

But at the same time, the above reasons already seem reasonable enough not to do this. You also need to take into account that modern gas boilers have a connection to electricity, which requires increased protection against electric shock even in an ordinary room, not to mention a humid environment.

You must understand that regulatory requirements for the safety of installation of gas-using equipment are developed for the benefit, protection of health, life and property of people and they are quite justified from a technical point of view.

Boiler connection

Gas heating boilers installation and configuration

The main parameter when choosing a gas boiler is its power. It should be sufficient to ensure the normal functioning of the heating network, but at the same time not excessive. With excess power, there is a high risk of cracking the heat exchanger. So-called acid condensate can also form when the return temperature drops below the gas dew point - 56 degrees. The high-power unit quickly warms up the system and goes into standby mode until the temperature drops to certain parameters. After cooling, the boiler turns on again, but powerful heat exchangers have high thermal inertia, so acidic condensate may form before it is reheated.

The optimal power should be determined on the basis of thermal calculations. The excess power must be within the permissible run-up. In a private house, you will have to do thermal calculations yourself or invite specialists. For apartment buildings, such data can be found in the technical inventory office.

Before installing the boiler, it is necessary not only to equip the room, but also to collect the necessary documentation:

Gas supply agreement - when installing a water heater, it will not be required.
Documents for the meter - without this device it is prohibited to connect gas heating and water heating equipment.
Documents from the BTI on amendments to the technical passport of a house or apartment. The new plan must take into account the location of the boiler room.
Technical passport for boiler equipment.

At this stage, you can submit an application to the gas service for the development of design documentation and specifications. You can install the device yourself before receiving the finished project, but provided that the room fully complies with the standards and is approved by regulatory services. Gas connections should only be made by gas service employees. A suitability statement must be obtained from a gas engineer before commissioning.

If you connected the boiler to the gas mains yourself, there is practically no chance of getting an engineer’s opinion. Such work should only be carried out by gas specialists. You can install the hydraulic and electrical connections of the boiler yourself. As a rule, all the necessary requirements and instructions can be found in the instructions for the device.
