DIY gas stove (115 photos): step-by-step guide on how to make an effective homemade gas stove

Home » Heating and water supply » How to make gas heating at home with your own hands?

If it is possible to connect to a gas main, then there is no better option than gas autonomous heating for Russian residents. Many owners of private houses choose this heating method due to its comparative cheapness. To save money, most people prefer to do gas heating at home with their own hands.

Types of gas furnaces

Devices can be of three types:

• Heating (gas stove for heating);
• Heating (designed to supply the room with hot water);
• Household (designed for a cauldron, performing the function of a bread maker, a source of heating for spacious rooms).

For example, a gas sauna stove is often installed with a heating and heating system; it can be lined with various materials, equipped with any type of burner, and is also made using different technologies and with various methods of heating water in containers.

Oven

Gas stove ovens are:

• gas;
• electrical;
• combined (with electric grill).

The optimal choice of the last two types of ovens, since they distribute heat evenly. However, with this choice, you must definitely consult with an electrician to see if the wiring can withstand the resulting load.

Gas ovens can be of 2 types:

• without convection;
• with forced air circulation.

The best choice is a gas oven with forced air circulation, since in this case the likelihood of cooking food that is not cooked through or that is burnt on one side is minimal.

pros

At the stage of modern economic development, gas is one of the most profitable and efficient types of fuel with high efficiency. The use of gas is particularly cost effective.

Today there are many different energy sources available on the market, despite this, a DIY gas stove remains popular and fully competes with factory-made products.

The advantages of using these devices include:

• Quickly, efficiently and efficiently heat the room to the desired temperature;
• Compact size and mobility (you can quickly move the stove to any place) due to the absence of a firebox and ash pan;
• No need for constant care;
• By installing a water tank, you can heat the water;
• Low resource consumption;
• Independence from public communications and other factors, which eliminates interruptions in work.

Features and history of creation

The first gas stove was invented back in the century before last, shortly after the general gasification in England. One of the gas factory workers named James Sharp was the first to think about using gas for cooking. It was he who, in 1825, designed the first analogue of a modern gas stove and installed it at home, significantly simplifying his life.

10 years later, factory production of such devices began, however, at first accidents often occurred, since people were not yet accustomed to the fact that gas must be handled very carefully

The period from 1837 to 1848 saw the evolution of the gas cooking appliance. The first models created by de Merle were not perfect enough. Afterwards they were improved by d'Elsner, who was an inventor. All these models still did not bear much resemblance to modern ones. But in 1857, the most advanced model of that time was invented by de Beauvoir, and it was this design that subsequently formed the basis for the creation of gas stoves for many years.

On the territory of Russia, stoves appeared only in the 30s of the last century, since mass gasification began after the revolution. However, the new devices were mainly used in apartments rather than private homes

Gas-powered units significantly saved housewives’ time, so they considered this feature a good compensation for the need for careful handling. Modern modified gas devices have a number of features

Among them there are both fairly new characteristics and those that were characteristic of all previous models.

• This unit only runs on gas. Therefore, it is necessary to either connect it to the general gas supply system, or supply fuel from a cylinder.
• A characteristic feature is the low cost of operation of this device. Even if you cook a lot, you won't have to pay a big utility bill because gas is cheap.
• A gas stove performs 3 main functions for cooking. It allows you to cook, fry and bake foods (if you have an oven).
• In most cases, the stove requires a hood, since sometimes the gas on which the device operates has a specific odor.
• A negative feature of the device is the need for extremely careful and attentive handling of it. Otherwise, there is a possibility of a gas leak, which could cause an explosion in the living space and tragic consequences.
• In the modern market of household appliances, gas stove models are presented in various embodiments.

Flaws

Gas furnaces have their own disadvantages, including:

• Mandatory access to a gas source;
• The use of fuel has certain restrictions according to standards;
• In some cases, you will have to obtain certain agreements and permits from government agencies and gas services, especially for non-residential premises;
• It is necessary to design the installation, which is quite expensive;
• Compliance with special safety measures.

To achieve the highest efficiency from a gas furnace, the room must be equipped with protective screens. They have surfaces that do not allow warm air to escape, but reflect it, heating the required space.

When using open-type burners, it is necessary to additionally design and install a ventilation system, chimney and provide air humidification. The latter are necessary because the gas burns oxygen, as a result of which the air becomes dry, which leads to pain in the head and throat.

Security and Protection

The most important thing for safety is the hose. Its quality and correct design play a big role. When purchasing, be sure to ask for a quality certificate. Rubber and bellows are suitable. It is strictly forbidden to take metal braided hoses.

Currently, gas stoves are installed using flexible hoses, which allows the device to be moved if necessary.

When a slab needs to be moved, there is no need to try to do it yourself. It's difficult and dangerous. At the same time, a specialist will check the quality of the hose. Leaks are most often recorded at the hose connection points. When installing, you must carefully inspect it for cracks and damage through which gas can enter the apartment.

The second thing you need to pay attention to is a professional inspection by a specialist. Many people forget this simple rule, and then emergencies occur with extremely unpleasant consequences.

Cases of explosions of gas stoves are often recorded in apartment buildings.

Gas service employees must check the condition of the device every three years. Sometimes the gas was turned off in the entire entrance due to a leak being discovered.

The gas service technician should regularly check the stove for serviceability for safety reasons.

Regarding the operation of the device: after and during use of the device, fresh air must enter the room. You cannot open the valve and then light a match. Gas spreads quickly and flames can break out anywhere there is gas. The color of the flame should be blue, another color is a signal of failure.

If you find a red or purple flame on the burner, you should contact a specialist to fix the problem.

Modern buyers are familiar with the gas control function. A special sensor that reacts to flame is attached to the stove. For example, he will report that the wind put out the fire and the water poured out of the kettle. In a home with children or elderly people, this function is necessary.

By purchasing a gas stove with a built-in thermocouple, the buyer provides protection against gas leaks.

Almost every store sells a detector that reports gas leaks. A very useful purchase if you cannot buy a device with gas control.

You should not save money on devices such as a gas leak detector. A timely detected malfunction of gas equipment will allow you to avoid a big disaster.

The kitchen must have good ventilation. The explosion can happen suddenly. It is very easy to miss the dangerous line of gas concentration. In a kitchen with a gas stove, 90 cubic meters of air should be supplied and removed. If these conditions are met, even an open burner will not affect the explosion - it will not happen. In an apartment building, you need to be sure that the ventilation system is in good condition.

A reliable ventilation system in the kitchen is a necessary condition if you have gas equipment.

The simplest advice that is so often ignored: if there is a smell of gas, do not light the fire. It is better to go out into the fresh air and call a special service. The smell coming from someone else's apartment is also a reason to report it to the service.

Gas furnace design

The design of a gas stove is similar to a model heated with solid fuel, with the exception of some features.

The oven consists of:

• Housings;
• Thermostat;
• Fuse (to shut off the gas supply during extinguishing);
• Sealed gas chamber;
• Chimney.

The difference is that the fuel is supplied through a supplied line, which is a special flexible hose connected to the burner.

In some cases, a balloon is used. It is placed in a special container in compliance with all safety regulations. A five-cc gas cylinder is capable of heating a room of up to 200 m2 during one heating season.

The air supply to gas equipment is adjusted using a door located below, which does not interfere with cleaning the burner.

Free heating, sir!?

Greetings to all blog readers!
Today it’s cool outside, it’s raining, and therefore the weather itself makes me think about talking about how to heat an apartment or house. At the same time, preferably with significant cost savings. People have special warm feelings for everything free. And if we talk about saving money on heating, then on the eve of the coming winter these feelings stimulate the brain, and this topic becomes extremely relevant. The Internet has already overheated from the number of requests on this topic. Some are interested in ideas on how to steal more electricity from the state and pay less for it, others are inventing ways to circumvent the law of conservation of energy. If the first group implements this idea successfully, but with the risk of meeting with an Energonadzor inspector, then for the other group of Kulibins things are, to put it mildly, unimportant. One can only be amazed at the ideas that are born in the heads of our inventors. Take, for example, an electric induction cooker. This thing in the kitchen is very useful in all respects. It combines the advantages of an electric and gas stove. It seems to me that the inventor himself and the manufacturers of these products could never have imagined that someone in Russia would have the idea of ​​​​using an induction stove to heat an apartment.

And the idea is the following. Electric induction cooker is used as a heater for a water boiler. The boiler fits into an existing water heating system. Everything is as usual here. The whole trick, according to the author of the invention, is to convert energy to power the induction cooker.

The stove is not plugged into an electrical outlet directly, but through a charger, a pair of batteries, and an inverter. An induction cooker with a capacity of 2000 W is used, which can be purchased for 1500 rubles. There is no need to invent anything here. The current power in it can be changed on the control panel, and the built-in timer automatically regulates the heating. For stable operation, you will need a 4000 W and 12 V inverter, two 250 Ah batteries.

The sequence of assembling the electrical circuit is clear from the figure. The question is how “free” the heat received in such an apartment heating system will be. Judge for yourself: energy losses from the outlet to the stove are inevitable, which means that the efficiency of the heating system decreases. It is more efficient, in my opinion, to plug the stove directly into an outlet. As for frequent power outages, this system is indeed capable of operating autonomously for some time. Or am I wrong?

But that is not all. Here is another option for “warm floor” heating, which uses this connection diagram for an electric induction cooker.

It is unlikely that an electric induction cooker alone will be able to effectively heat an apartment. It would be interesting to know the opinion of those who have already experienced such a heating system in practice. Write and share your ideas. I think that the problem of home heating with the annual increase in energy tariffs worries the majority of Russians.

Judging by this sunset, which looks like a huge glow, there will be frosts at night, which means that the solution to this problem is urgent.

Options

Before you start making a gas stove with your own hands, you need to decide on its parameters, such as:

• Material of manufacture;
• Burner type;
• Location of the water tank.

Increased gas pressure under the throat

A significant obstacle to speeding up the operation of blast furnaces is the insufficient gas permeability of the charge materials column. As the amount of blast increases, the speed and lifting force of the gases in the blast furnace increases. Upon reaching certain speeds, the lifting force of the gases can balance the column of charge materials, and their descent stops.

In order to maintain a smooth flow of charge materials and at the same time speed up the furnace progress, it is necessary to reduce the speed of movement of the furnace gases, maintaining and even increasing the amount of blown air. This is achieved by increasing the gas pressure in the furnace; at the same time, its volume decreases, and consequently, the speed of movement decreases, which makes it possible to increase the amount of blown air.

An increase in pressure is achieved by reducing the cross-section of the gas pipeline by installing a throttling device. This measure can significantly reduce dust removal, which also improves the performance of the furnace.

Switching the furnace to operate with increased gas pressure under the top significantly changes the distribution of gas flows in the furnace; for example, the peripheral flow of gases increases. Peripheral loading allows better use of the reducing power of gases. However, it is necessary to ensure good gas treatment of the central zones of the furnace, that is, materials located along the axis of the furnace must have sufficient gas permeability. Thus, when the gas pressure at the top increases, the preparation of the charge should be improved.

An increase in pressure increases the density of gases, which ensures better processing of charge materials and an increase in the rate of oxide reduction, and the higher the pressure, the greater this effect. Therefore, transferring furnaces to work with gas pressures of 176 - 245 kN/m2 (1.8 - 2.5 atm) is the immediate task for blast furnace workers. At the advanced ones, the Cherepovets Metallurgical Plant, etc.), the gas pressure at the top has already reached 196 kN/m2 (2.0 at).

Increasing the gas pressure under the top made it possible to reduce coke consumption by 1 - 3% and increase productivity by 5 - 10%. The results obtained depend on the smelting conditions - pressure, quality of raw materials, fuel, etc. The practice of operating blast furnaces confirms the advisability of further increasing the pressure under the top.

As the gas pressure in the working space of the furnace increases, it is necessary to further increase the reliability and durability of the structural components and equipment of the blast furnace - tuyere hoses, atmospheric valves, charging apparatus, air and gas pipelines. Thus, the durability of filling devices is currently still insufficient and does not yet exceed 10–15 months.

At the same time, the question arises about using the energy of compressed gases, which, in particular, will reduce the cost of compressing the blast, for example, as a result of installing gas turbines in the place of gas throttling.

Materials

You can make a gas stove yourself from stone, refractory brick or metal.

Stone structures heat up much more slowly, about five hours, but retain the accumulated heat for longer than four hours, compared to metal products. Brick structures have similar characteristics.

Metal stoves heat up quickly; in three hours they can heat a room with an area of ​​up to 50 m2. However, they cool down quickly. The advantages can be considered light weight, ease of manufacture, and if you make the outer cladding with fireclay bricks, then the shortcomings in heat transfer will be completely smoothed out.

Necessary equipment

If you decide to connect a tabletop or built-in gas stove yourself, then first of all you need to prepare all the equipment. To complete the work you will need:

• flexible hose connecting the stove and the central gas pipe. Instead of a hose, you can use metal pipes, but in this situation the installation process will be more difficult and will require special skills. Since pipes can be connected to each other in the case of gas supply only by welding;
• a ball valve that allows you to shut off the gas supply, for example, in the event of a leak or other emergency, as well as for carrying out repair/preventative work;

In accordance with safety requirements, the tap must be made of brass and have a nickel coating.

• tools: adjustable wrench, screwdriver;
• gaskets and sealing tape for sealing threaded connections;
• dielectric coupling. The equipment is required if it is necessary to connect the stove to the electrical network, for example, if there is an electric ignition;
• soap solution and sponge to check the tightness of the system.

Choosing a flexible liner

What kind of hose is needed? The first thing you need to pay attention to when preparing the equipment necessary to complete the job is the choice of flexible gas supply. Flexible connection of a stove or oven can be done using:

Flexible connection of a stove or oven can be done using:

rubber reinforced hose. The eyeliner is made of vulcanized rubber. Reinforcement with textile thread gives the product additional strength. The hose is durable and has minimal cost. The equipment can operate in the temperature range from -35°C to +50°C. The average service life is 5 – 7 years;

Rubber gas hose with thread braid

rubber hose with metal braiding, which gives the product additional strength and durability. The equipment can operate properly for 8 – 10 years;

Rubber liner with durable metal braid

bellows hose made of metal. The product is distinguished by its high cost and large margin of safety, as well as a long period of use (over 10 years).

Metal gas line

To increase strength and service life, the bellows liner can be protected with a plastic braid.

Metal gas hose with additional protective braiding

When choosing eyeliner you should also consider:

• hose length. According to safety regulations, the hose must not be stretched. The maximum length of the gas hose is 1.5 m;
• type and size of thread. If the thread on the flexible connection does not match the size or type of thread on the gas pipe or gas stove, then the installation of additional equipment - adapters - will be required, which can reduce the level of tightness of the gas supply system.

Selecting a seal

The rules for connecting a new slab require sealing of threaded connections. To seal connections in the gas supply system, it is recommended to use:

FUM tape. The sealing material is laid in a thin film, which facilitates the method of application. Average service life – 10 – 12 years;

Sealing tape for threaded connections

Loctite 55 thread is a sealing material made from high-strength threads. In most cases, it is supplied in special plastic containers. The period of use of the material is no more than 10 years.

Sealing thread for gas system

Tank location

There are several ways to place the tank in the bathhouse; the container can be:

• Removable;
• Built-in;
• Remote (i.e. placed in a separate room).

In a built-in tank, water heats up much faster, since the tank is installed directly on top of the stove or welded to the side. To install a remote tank, you will need to install a pipe system.

Gas supply to residential buildings

Gas facilities must be equipped in full compliance with the requirements of the approved “Rules for the installation and operation of gas equipment in residential buildings.”
Installation of gas networks, gas equipment and domestic gas stoves in a residential building is carried out by a special organization according to an approved project. The project includes the development of an entrance to the building (yard gas networks), as well as gas distribution inside the house. For domestic needs, it is allowed to use low pressure gas (not exceeding 100 mm of water column). In order to maintain constant pressure in front of appliances (oven, stove, water heater), an apartment regulator-stabilizer is installed.

The depth of the gas pipeline in the area, which ranges from 1.2 to 1.7 m, is taken depending on the climatic region and the depth of soil freezing.

The water vapor contained in the gas cools in winter and creates ice plugs in the gas pipeline, thereby blocking gas access to consumers. Therefore, in projects for yard gas networks, the issue of draining condensate from the network must be provided for and correctly resolved.

In cases where the main gas networks are located at a great distance from the village and it is not practical to lay expensive transit gas pipelines, gas supply is carried out using imported liquid gas. The product of secondary distillation of oil - propane-butane - is used as a flammable gas.

For a kitchen stove designed for one family, with low gas consumption, two cylinders are needed, one of which is a working one, the other is a spare one. The capacity of the cylinder is 50 or 80 liters, which sufficiently provides a family of 4-6 people for one week. The cylinders are installed in special metal cabinets at each home. Gas pipelines from cabinets with cylinders to the place of gas consumption are laid by a special organization.

Gas stoves and tagans are installed in kitchens whose height is at least 2.2 m. In this case, the kitchen must have an exhaust ventilation duct measuring 130x130 mm, a window or an opening transom in the window. In kitchens without windows, it is allowed to install gas stoves or tagans if there is a ventilation duct and direct access to a non-residential premises that has a window with a window or an opening transom. In kitchens with a height of 2 to 2.2 m, as well as in kitchens without windows, each burner must have at least 4 m3 of space.

There is no kitchen in the house and it is impossible to allocate a separate room for it; it is allowed to install gas stoves and tagans in a corridor with a height of at least 2.2 m, which has a window and a ventilation duct. In this case, the width of the free passage between the installed slab or tagan and the opposite wall must be at least 1 m.

The internal volume of kitchens or corridors equipped with gas stoves or tagans without exhaust hoods must be no less than: for a stove or tagan with 2 burners - 8 m3, for a stove with 4 burners - 16 m3.

When installing exhaust hoods over stoves or tagans, it is allowed to reduce the volume of the room: with a 2-burner stove - up to 6 m3, with a 4-burner stove - 12 m3.

Gas water heaters are installed in bathrooms or combined bathrooms, the internal volume of which is at least 7.5 m3, equipped with ventilation ducts and having a floor grille with an area of ​​at least 0.02 m2 or a gap between the door and the floor of at least 3 cm to ensure air flow. The doors of these rooms must open outward.

Heating stoves and cookers operate on gas if they are connected to separate chimneys. Burners installed in stoves and stoves must be of the ejection type and ensure complete combustion of gas.

Ejection burners (unlike diffusion burners) use the energy of the gas jet to draw ambient air into the burner, resulting in a mixture of gas and air burning in the burner.

In the views or valves of stoves operating on gas, holes with a diameter of 15, 20 mm must be made for constant exhaust from the firebox.

Preparation

When sketching drawings of a gas furnace, it is necessary to indicate the exact parameters of each element.

1. At the installation site, prepare a level base and cover it with a fire-resistant layer.
2. Lay fireclay bricks on top in two rows.
3. Walls located less than one meter from the stove and the ceiling must be protected with non-combustible material.
4. Most stoves heated by gas have almost the same design, so their assembly and installation is also identical.

It is not difficult to assemble it yourself; the main thing is to properly prepare the room before doing so, following the recommendations of specialists and observing safety rules.

Pipe system

The system itself consists of correctly selected and laid heating pipes, which connect your radiators and boiler to each other. There are two types of such pipeline laying systems: one-pipe and two-pipe.

When a heating system is being designed, a two-pipe supply scheme involves installing two pipes on each of the batteries, the so-called “supply and return”. Through one of them (supply), the coolant (water) enters the heating device, through the other (return), having already cooled, it returns to the boiler. The use of such a wiring diagram makes it possible to achieve the same degree of heating of the coolant in all radiators in the house. Two-pipe type wiring is divided into two main types:

1. Connecting radiators in parallel-series (one closed ring).
2. Using a collector, to which all radiators are connected with separate hoses (pipes).

The second type of connecting radiators makes it possible to regulate the temperature of each battery. But it also has a noticeable financial disadvantage, this is the need to install a large number of metal-plastic or other pipes for heating to provide connections to radiators. A single-pipe heating circuit made of metal-plastic pipes functions like this: the heated coolant (water) simply flows through the pipes from one radiator to another. Simply put, such a system is sequential, and this leads to a gradual cooling of the coolant along its route. This means that the last radiator in the chain will always be significantly cooler than the first battery. The main advantage of a single-pipe heating system made of metal-plastic pipes is the low cost of its arrangement.

Also very important is the degree of thermal insulation of your home. If you have taken all measures and insulated the walls, ceilings, floors, installed new good windows, and you have a modern, high-quality entrance door (doors). Then the heat loss of your heating system will be minimal and during the season, you will spend much less money than you planned.

Installation rules

When installing the stove, you need to pay special attention to the following:

• The distance between the walls and the stove should be more than 5cm;
• The foundation must protrude beyond the edges of the stove by at least 10 cm;
• The height of the connector for the burner with an overlay should be 61.5-68cm, without an overlay - 47-55cm, width - 51.5-66.5 and 35-45cm.

Many craftsmen in the manufacture of gas furnaces do not stop there and constantly improve their products, equipping them with various devices.

There are homemade heaters with fully automated operation, equipped with special blowers that control the flow of warm air.

Oven

The following types of ovens are distinguished:

Gas

Gas stoves cook quickly, but it is difficult to adjust the temperature in them. So, setting the temperature to 50 ℃ (useful for drying vegetables) is very difficult. However, low energy costs (especially if you install a gas meter) and ease of operation often compensate for these features.

They differ from each other in the location and number of heaters. In inexpensive models, the burner is located only at the bottom, but in more expensive ones there is also an upper burner - a grill. Some devices are equipped with a fan that mixes the air and prevents the formation of “cold” zones, which means the dish is baked evenly.

Electrical

Using this option is much more convenient due to more precise oven settings. Those who love to bake should take a special look at these units. Disadvantages: energy costs, long warm-up and cool-down times.

Devices of the simplest modifications have two heating elements - at the top and at the bottom. More complex models already have four heaters: more side heaters are added. Convection allows you to maintain the same temperature throughout the oven and is present in devices of medium and high price levels.

Every housewife should decide which is better, focusing on her own feelings: some are more accustomed to cooking in a gas oven, while others are more comfortable in an electric cabinet.

Making a boiler

From all of the above it follows that gas generator-type boilers are considered the most economical and high-quality elements of the heating system.

The main problem in purchasing and using such a boiler is the cost of this product. For example, the simplest model of such a boiler, which is manufactured by domestic companies, costs about $1,000.

If you choose imported manufacturers and improved models of such boilers, the price can increase 5 times. It follows from this that gas generator boilers cannot be called publicly available. But there is a more economical option for purchasing such a boiler. This method is a wood-burning boiler, made with your own hands. To make such a boiler, you need to use special drawings that are developed and posted on the Internet by craftsmen.

Gas-generating boilers developed by folk craftsmen have not only a low manufacturing price, but also other positive aspects. The use of a homemade boiler, manufactured according to ready-made drawings, provides for a significantly longer operating time of the boiler on one load of fuel into the combustion chamber. Due to the fact that in factory boilers, special nozzles are installed under the combustion chamber, through which air is supplied, pumped by forced systems, the combustion process of solid fuel is almost doubled. In addition, the direct dependence of such a boiler on the electrical network ensures that the system operates correctly only when the boiler is connected to the network. Homemade boilers are devoid of such elements, which allows them to work better and longer.

Some homemade boilers are equipped with two solid fuel combustion chambers. This allows the fuel to be burned in a consistent manner. When one chamber lights up, the fire in the other chamber automatically goes out. This helps achieve the highest efficiency with maximum fuel burning time in the boiler. Some design features of homemade boilers make it quite easy to control the process of fuel combustion in the boiler. This is achieved by correctly positioning the grates under the fuel bunker.

Almost all homemade boilers, drawings of which can be easily found on the Internet, burn all contaminated particles, such as essential oils, various resins and alcohol. This became possible due to the fact that in such boilers there is a separate zone of additional combustion. Contaminated air from the combustion chamber enters this zone. It is this air that contains polluted particles that are burned separately. It follows from this that a minimum amount of harmful particles enters the atmosphere, which can enter the heated room through the cracks and pores of the building material.

Solid fuel boiler drawing

A homemade wood-burning boiler is intended not only for the use of wood fuel. In such boilers you can use sawdust, peat briquettes or coal as fuel.

The use of such fuel materials involves the appearance of slag, which must be removed. This is necessary for the combustion process to occur correctly. In order to perform screwing, the boilers are equipped with a special hole under the combustion chamber. It is through this hole that you can insert a poker and destroy the slag crust. This hole is closed with a small door, which blocks the flow of excess air into the combustion chamber.

Drawings of homemade boilers are developed on the basis of finished factory products. The main difference is considered to be the changes made in design and production terms. The positive side of such boilers is the ability to heat a larger amount of air coolant with the same volume of the combustion chamber.

As practice shows, using air as a coolant allows you to create a more comfortable microclimate in a heated room. When using such a coolant, you can heat the air in the room in a short time. In addition, heat losses in such a heating system are minimal. Do not forget about the significant savings in money that must be spent on purchasing a special coolant. In addition, complete tightness of the heating system with air coolant is not necessary.

Chimney construction process

The complexity of the process of constructing a chimney for a potbelly stove in a country house directly depends on the location of the stove in the room. For example, bringing a pipe out through a window is much easier than making a hole for a chimney in the roof. In this regard, before installing a potbelly stove, you should take into account the design features of the building.

Safety rules and structural measurements

If you plan to install the stove outdoors, then installing a chimney will not cause much difficulty, the main thing is to choose a suitable location

It is important to remember that the stove structure should be located away from flammable objects and active recreation areas

Constructing a chimney indoors will require knowledge of safety rules that will help avoid fire. The material from which the pipe is made must have increased heat resistance and can easily withstand temperatures above 1 thousand degrees. If you plan to install a potbelly stove near walls lined with clapboard or plastic, then the part of the wall located in close proximity to the stove is sheathed with fireproof material.

Don't forget to decide on the pipe size

The hole through which the chimney will enter the ceiling must also be decorated with non-combustible materials, since the entire structure becomes very hot when the stove is operating. For these purposes, a special glass is used to prevent contact of the hot pipe with the edges of the hole. If there is more than one potbelly stove installed in a building, then a separate smoke exhaust system is made for each of them.

After calculating the diameter of the pipe for the potbelly stove, you will need to calculate the total length of the pipeline, but first you need to accurately determine the location of the stove in the room. Then determine the specific location where the chimney will be vented outside. When measuring the length of the pipeline outdoors, you need to take into account that the height of the pipe above the ridge should be 1.3-1.7 meters.

It is more difficult to carry out installation work indoors

Installation of all system elements

Installing a stove installed outdoors is not difficult. To assemble the system, you will need a pipe of the required diameter, which is placed on the pipe extending from the potbelly stove. The pipe must be put on the pipe, and not inserted into it. Otherwise, smoke will leak out at the junction of the nodes. The procedure for installing a smoke exhaust system in a room is much more complicated and consists of several stages:

• the pipe section is securely attached to the furnace pipe;
• the pipeline is extended using connecting elbows;
• the smoke exhaust is passed through a passage glass and discharged onto the roof or behind the wall;
• all connecting nodes are securely fixed.

A section of pipeline located outdoors must be insulated with heat-resistant material. During operation of the potbelly stove, condensation inevitably accumulates on it. To get rid of the condensate accumulated in the system, a tee is installed on the outer section of the pipeline, equipped with a faucet for discharging liquid. In the place where the horizontal and vertical pipelines connect, an inspection window is made to make cleaning the chimney easier.

The final stage is checking the functionality of the smoke exhaust system. If you managed to properly make a chimney for a potbelly stove, then after igniting the stove the necessary draft will be created and the smoke will quickly be discharged outside. During the combustion process, you need to ensure that smoke does not leak into the joints of the nodes. If a smoke leak is detected, the connections must be sealed using heat-resistant sealant.

Appendix 1

Today I received another letter asking me to explain where to get capillaries and, in general, how to make an injector. It was even proposed to use electrical erosion. I had no idea that this could cause problems. So, I do it this way. First of all, I got used to using M3 screws for the injectors (a regular screw with a 3 mm metric thread). So, take your box of M3 screws, dump it out and distribute it in an even layer. Then take a magnet and pull out all the attached screws. As a result, you will be left with screws that do not tighten. The fact that they look the same as the others should not fool you. These are plated brass screws. In the photo under number 1. If there are no brass M3s, nothing prevents you from doing this with M4.

Next, you have five options: - immediately drill a hole with the required drill diameter. But this is for fairly large holes and with a precision drill. - drill on both sides of the screw with a large drill, but not all the way. Then pierce this jumper with a needle or drill it with a small drill. - drill with a large drill, and then fill the hole with PIC solder, and then work with it, which is much easier. - drill with a large drill, and then use POS solder to solder a stainless wire of the appropriate diameter coaxially into the screw. And then pull out the wire. And finally, you can solder a capillary of the appropriate diameter into the drilled hole using low-melting solder. So, capillaries, that is, thin tubes. Under the number 2 are capillaries from instrumentation instrument recorders. It’s unlikely that this advice will make you feel any better. But number 3 is the most realistic option. When the doctor gives you an injection, don’t groan, don’t feel sorry for yourself, but gather your willpower and ask the doctor to give you the needle as a souvenir. He will give it back, he doesn’t mind. Thus, over the course of your sick life and that of your loved ones, you will collect an extensive collection of capillaries. And if you are lucky enough to give injections with imported syringes, the range will become much richer. They also have very thin needles, for example for vaccinations. Don’t forget to also collect a collection of steel elastic wires for cleaning capillaries - number 4. Number 5 - my new gas stove came with a whole set of nozzles with different hole diameters. And finally, 6-end clamps for mounting multi-core electrical wires. A whole bunch of different diameters.

heating elements

For heaters: types you will have to buy heating elements: 220 V electrical appliances with open heaters are extremely dangerous. Here, pardon the expression, you need to think first of all about your own skin and property, whether there is a formal ban or not. It’s easier with 12-volt devices: according to statistics, the degree of danger decreases in proportion to the square of the supply voltage ratio.

If you already have an electric fireplace, but it doesn’t heat well, it makes sense to replace a simple air heating element with a smooth surface (pos. 1 in the figure) with a finned one, pos. 2. The nature of convection will then change significantly (see below) and heating will improve when the power of the finned heating element is 80-85% of the smooth one.

Types of heating elements

A cartridge heating element in a stainless steel housing (item 3) can heat both water and oil in a tank made of any structural material. If you buy one, be sure to check that the kit includes gaskets made of oil-heat-gasoline-resistant rubber or silicone.

A copper water heating element for a boiler is equipped with a tube for a temperature sensor and a magnesium protector, pos. 4, which is good. But they can only heat water and only in a stainless steel or enameled tank. The heat capacity of oil is much less than that of water, and the body of a copper heating element in oil will soon burn out. The consequences are severe and fatal. If the tank is made of aluminum or ordinary structural steel, then electrocorrosion due to the presence of a contact potential difference between the metals will very quickly eat away the protector, and then eat through the body of the heating element.

T. called. dry heating elements (item 5), like cartridge ones, are capable of heating both oil and water without additional protective measures. In addition, their heating element can be changed without opening the tank and without draining the liquid from there. There is only one drawback - they are very expensive.

What is a gas burner and what does it consist of?

Any device designed to burn liquid and gaseous fuels has a main component - a burner. It is responsible for the formation of a uniform flame. The fuel mixture can be of different quality, but a well-thought-out method of fuel supply will ensure complete combustion of any combustible mixture.

Atmospheric gas burners for boilers have a very simple design

The most important indicators of a high-quality device for burning gas are silent operation and the absence of the release of harmful compounds when burning fuel, in particular carbon monoxide. A modern household gas burner for a heating boiler is a simple device that has gone through a long process of modernization. Some old designs, produced in Soviet times, made a lot of noise and were far from safe, especially in strong winds.

Many indicators, including noise level, are influenced by the design features of the combustion chambers. In new models of burners, much attention is paid to the convenience of ignition and uniform flame supply. The design features of a gas burner for space heating are very simple:

• gas ignition is provided by the ignition system;
• the gas ignites in the nozzle;
• automation is designed to control basic indicators: temperature, uniformity of gas distribution, emergency shutdown;
• the presence of fire is monitored by a special “flame sensor”.

From the room, by-products of gas combustion must be removed outside so that harmful impurities do not fill the space. To remove gas, you need a chimney with good draft. This is the only drawback of gas heating. The gas burner device itself is constantly being improved, including the following indicators:

The noise level of a gas burner depends on the design of the combustion chamber

• heat generation schemes;
• rational flow of oxygen;
• methods for removing soot and carbon dioxide.

Gas burners for boilers: basic requirements and operating diagram

The heat released during gas combustion is concentrated in a heat exchanger, from where it is transferred to the coolant. Along with a small amount of heat, part of the combustion products is released into the atmosphere. A chemical reaction of heat release occurs: at high temperatures, the combustion gas combines with oxygen coming from the air. The operating principle of a gas burner is based on the combustion of gas and the release of heat. Water vapor and carbon dioxide are by-products of a chemical reaction that produces heat.

Among the dangerous substances are nitrogen oxide, carbon monoxide and some resinous components. Because of this, special requirements are placed on the hood and chimney - good draft is important.

According to modern requirements, in any mode, gas burners for heating boilers with automation (and other varieties) must be low toxic. It is required that during the combustion process only slightly toxic gases and a small amount of soot are released, which is a general condition for the use of most types of raw materials for heating.

A properly thought-out method of fuel supply will ensure its complete combustion

Basic requirements for a boiler burner:

• accessibility for self-installation;
• clear design diagram;
• long period of operation;
• reliability of operation;
• low noise threshold;
• ease of switching modes;
• possibility of working on another type of fuel;
• complete combustion of gas;
• high environmental performance (few harmful combustion products are released).

As you know, a cheap product indicates low quality products and a short service life. Often repairs are impossible, especially if there is no warranty period and no factory certificate. There are always high-quality household gas burners for heating boilers on sale. Their price is quite acceptable for most consumers.

Criterias of choice

It is important to choose a gas stove for a garage taking into account the main characteristics. Let's look at them in more detail

Power

This characteristic will allow you to save not only on the purchase of the optimal stove option, but also during operation. A powerful stove will heat the room faster, but gas consumption will also be higher. A low-power stove will not be able to heat the room

Therefore, it is important to know even approximately the required power of the equipment to heat your garage

You can calculate this characteristic yourself. To do this, you will need to determine the volume of the entire room and the cubic capacity of the gate. Multiply these values ​​by the coefficients for the materials from which the garage itself and the gate are made. The resulting result will be the approximate power of the heating unit.

Material

This characteristic affects the longevity of your stove. When purchasing, you will need to familiarize yourself with the thickness and grade of steel of the body and firebox. When using structural steel, the thickness of the firebox sheet should be from 6 mm. It is better if heat-resistant steel or alloys were used in heat guns or convectors for the production of the body and grilles.

Alloy steels with a high content of chromium, silicon, and molybdenum are the best option for the production of parts exposed to high temperatures. Another option for a material that is not exposed to aggressive environments is stainless steel.

Winter summer

If the use of heaters is planned to be short-term and during the warm season, there is no point in buying expensive, powerful equipment. Small heat guns or convectors or a homemade stove that burns gas in a closed chamber will help here.

For winter and low temperatures, you will need to purchase a powerful gun or several infrared heaters and install them throughout the room. At this time, the efficiency of technology is an important factor.

In this matter one should not go to extremes. You can’t try to save money and buy low-quality Chinese equipment for pennies and throw it away after a short time. But you shouldn’t buy an expensive, powerful heat gun from leading manufacturers to heat a small garage during short visits.

Stages of work

Each stage requires special attention, from preparing the gas cylinder to decorating the finished structure. A pre-prepared drawing will help you make the necessary device as quickly as possible. To speed up the process, it is necessary to prepare all materials and equipment in advance.

Required Tools

• grinder for cutting;
• drill for preparing holes;
• welding to connect component elements;
• bolts for fastening individual components.

To prepare the container and mark it, you may need a hammer, marker or an adjustable wrench. Some accessories may be replaced, but these tools are sufficient for quality preparation and assembly.

How to cut a balloon correctly

You should proceed to cutting after it has been completely cleared of gas residues. This must be done according to pre-made marks. The work is carried out carefully so that the edges are as smooth as possible. After cutting, it is necessary to clean and polish.

Making Tips

To make a practical and reliable thing, you need to think through the concept in advance and draw up a drawing. The diagram is important not only during manufacturing, but also when calculating the necessary materials. To ensure safety, you should use personal protective equipment and follow proper techniques when working with explosive objects.

Stationary structures, traveling options - everything can be made with a little effort and spending a little time.
