The best gas convectors 2021. Which gas convector is better to buy

Heating an apartment or private house is one of the key expenses for utility bills during the cold season. For this reason, people tend to choose the cheapest heating technology for their home. It's no secret that the most profitable fuel is natural gas. It has a high efficiency, is significantly cheaper compared to electricity, and is absolutely safe if all necessary rules are followed.

Recently, so-called gas convectors have become increasingly popular. Such heating equipment appeared on the shelves of domestic stores not too long ago, so not all people understand what features of the device they need to pay attention to when purchasing. We decided to help you solve this problem and developed a rating of the best gas convectors. Here we will talk in detail about the key operational characteristics of such devices, and also give a number of useful tips that will definitely help you when purchasing this heating equipment.

What does a gas convector consist of and how does it work?

A gas-powered convector is a ready-made mini-heating system.
If you need to heat one room, for example, a large hall in a country house, just install the device and connect it to a power source - a natural gas line or cylinders. There is no need to purchase a boiler, pipes, pump, or radiators separately. The operating principle is based on a change in the characteristics of the fuel as its temperature increases. The air flow passes through the heat exchanger, heats up and moves up to the ceiling. It is replaced by colder portions of air that follow the same path. This process is called convection, and the units themselves are called convectors.

Modern heating devices meet safety requirements, are efficient in operation, and in terms of their external design and control method are completely suitable for installation in a residential area.

The traditional and technically sound installation location is the section of the wall under the window: heat loss in this area is considered to be maximum.

The location of the convector is determined by the principle of its operation: the lower the device is installed, the more efficiently the air in the room will be heated

The design of a gas convector is a combination of the following components:

Housing or casing that performs two functions: protective and decorative. This is a metal box coated with heat-resistant anti-corrosion paint, with holes for air circulation and fittings for installation.
A gas burner is an element responsible for burning gas. It is interfaced with a heat exchanger and equipped with an igniter with an electrode, which is used to ignite.
The heat exchanger performs the main function of heating the air. The larger its surface area, the more efficient the heating will be, which is why the ribbed configuration is common.
Smoke exhaust system . The combustion products of gas heating units are removed in two ways: naturally or forcefully, using a built-in fan. In the first case, combustion is supported by air intake from the room, in the second - from the street, through a coaxial pipe.
Valve that allows you to regulate the pressure of fuel entering the combustion chamber. Connected to the thermostat and responds to its signals.
Thermostat . The combination valve is controlled by a thermostat, which can be adjusted to a comfortable temperature.
The control system of modern models is automated. If an emergency situation occurs: a decrease in pressure, a shortage of combustion air, a fan failure, or a flame extinguishment, the convector stops working.

Heaters with tangential fans increase the rate of pumping heated air and warm up the room faster.

To increase the heating properties, the walls of the housings of expensive models are made thicker. The units function not only as convectors, but also as radiators - they transmit thermal radiation from heated metal to the surrounding space

All gas models are universal in relation to the type of fuel. They can operate on both natural and bottled gas. Requirements for combustible materials are set out in GOST 5542-2014 .

Principle of operation

A gas convector is an autonomous device for heating rooms, operating on the principle of natural convection of air masses. Cold air is at the bottom of the room, heating up, it rises until it begins to cool.

The heater operates as follows:

a heat exchanger is placed inside the device, which is connected to convection channels;
when gas is burned, it begins to heat up;
air masses pass through the heating element and are warmed;
the heated air enters the room.

Installation

The fundamental document for installing heating equipment is the operating instructions included with the product. It provides a description and sequence of installation operations.

Peculiarities

Wooden house. Thermal insulation of wooden structures is required. It will be necessary to make fire breaks to the roof. The surface of the coaxial chimney heats up slightly due to its design features; there is no need to insulate it.
Distance from the floor. The minimum distance to the base is no less than 10-15cm. This is necessary for efficient supply of cooled air. Increasing the distance will lead to the formation of a lower cold layer, increasing the temperature under the ceiling.
Location along the walls. It is limited to the point of external supply of the main pipe for a natural fuel convector and the outlet of the coaxial chimney. The use of a balloon option adds freedom to choose the installation location. It is necessary to take into account the location of people and the location of barriers to heat flow in the form of furniture.
Connection. Gas pipe laying, wiring and connections are carried out by accredited gas service specialists. The connection to the steel pipe is made with a flexible hose.
Commissioning activities. The presence of representatives of the local gas service is required. Based on the test results, a note is made in the accompanying documentation for the gas converter.

Video description

Video instructions for measuring gas flow with a convector:

Cast iron. Sufficiently heat-intensive - able to retain heat for a long time after being turned off. Disadvantages: fragility, heavy weight.
Duralumin. Strong, lightweight, durable. The downside is that it is quite expensive.
Copper. Durable, plastic, not subject to destruction. The disadvantage is the very high cost.

A convector with a cast iron heating circuit is most optimal for domestic use. It is durable and retains heat for a long time. However, during installation and operation it is necessary to take into account its increased fragility.

Automation

Convector gas heating from bottled gas can be controlled either by a simple automation system based on a relay and thermostat, or by a more advanced software module that sets many operating parameters. The final cost of the device largely depends on the type of automatic unit used. However, the more factors are taken into account in the settings, the more economical the consumption will be and the more comfortable the living conditions will be.

How to choose a good gas heater?

We will conditionally divide gas heaters into three types - portable, portable and stationary . We will divide according to the type of power supply - a compact gas cylinder (threaded or collet) for portable models, connection with a hose to the main line, gas holder or cylinder for portable ones (naturally, the design and weight itself must imply the ability to be carried), a natural gas main line or a cylinder for stationary ones, either too heavy to carry, or purely physically mounted somewhere.

Portable gas heaters , so beloved by fishermen, hunters and tourists, should be assessed by the reliability of installation (especially on uneven surfaces) and the quality of gas heating, both of these parameters being closely related. After all, a heater that has fallen on its side may also begin to spit out an open flame if the liquid phase entering it from the cylinder when it is turned over does not evaporate - and this, you understand, is unsafe. If the heater has the ability to be used as a hotplate, you have a bingo: with such a device you can both warm up and boil tea, and on larger models you can even fully cook food. However, keep in mind that versatility has a downside - a regular camping stove will boil water faster... but it won’t warm it either.

Portable gas heaters are more of a “dacha-garage” option. Their power is higher, and, therefore, the efficiency will already be noticeable in terms of gas costs - simple models with a metal mesh should be put aside, preferring “ceramics”, which will provide the same level of “infrared power” at lower gas costs and with a better resource . The main thing is not to forget that any infrared heater, including a gas one, heats the surfaces it is directed at, not the air - therefore, it is stupid to compare the power of infrared heaters with heat guns, which are much more effective for heating (but are also more voracious, and oxygen they “eat” only on the way). But the most important thing is that it is extremely desirable to cut off the gas when the flame goes out or overturns: you understand, no one will constantly monitor the heater at home and especially in the garage, and it is not difficult to accidentally touch it in the same garage. Saving on security is such a thing.

If we take a stationary heater , then first of all its thermal power is important, of course - it would be stupid to spend money on the heater itself, and then spend time and effort on installing it, only to discover that it doesn’t really warm up the room. Shutting off the gas when the burner goes out is mandatory here, and automatic re-ignition is desirable: however, “purely mechanical” models also have their advantages, which are less convenient to use, but can work in the most remote village, where even a cardiologist can read the oscillogram of the voltage in the socket will grab his head.

Floor or wall installation

According to the installation method, all convectors are divided into:

floor;
wall-mounted

Floor-standing ones are distinguished by greater power and heat transfer, so they are installed in spacious rooms - workshops, garages, warehouses. To ensure that heavy units remain stable, a strong and level base is prepared before installation.

Wall-mounted units are household convectors suitable for living rooms, halls, and halls. They take up minimal space, as they are attached directly to the wall, through which the chimney exits.

The traditional installation location is under a window or near a door. A warm curtain prevents the entry of cold air through cracks in window or door openings, creating a cozy microclimate in the house

To reduce the load on the wall, the heat exchanger in modern budget models is made of steel rather than cast iron.

The cost of floor-standing and wall-mounted gas convectors is almost the same; to a greater extent it depends not on the type at the installation site, but on the technical characteristics and materials from which the main parts are made.

Selecting the power of the device

The comfort of those living in a heated room depends on the correct choice of power. On average, approximately 1 kW is required for a volume of 30 m³. Devices with power from 2 kW to 12 kW are intended for domestic use.

There is a large assortment of heating devices with a power of 2-6 kW with a steel heat exchanger on the market. They are attractive with their design and low price, but their service life and efficiency are lower than their analogues with a cast iron heat exchanger.

Considering the likelihood of ventilation, drafts, and insufficient insulation, you need to take a unit with a small power reserve. Let’s assume that a 40 m³ room requires a 2 kW convector.

Flaws

All of the above belongs to the category of advantages of gas convectors. Next we will look at the shortcomings. All pros and cons are such only in the context of this article. For example, if we take the speed of acceleration of a car, then high engine power can be considered a plus, and driver safety and fuel efficiency can be considered a minus.

This is the case with gas convectors. The biggest disadvantage of this device is that you need to drill into the wall to install it. And not just make a hole, but a hole for a coaxial gas outlet. The gas outlet is a special tube in a pipe through which exhaust gases exit, and the fresh air necessary for combustion enters the convector through an external pipe. It is logical to assume that there should be a hole in the wall in the place where the convector is located, and if they are located under every window in every room, imagine how many holes there will be in your house! And these holes cannot be hidden or brought to one place. And remember another hole in the wall for gas supply. A vivid picture of a house appears before your eyes, shrouded in gas pipes and full of holes in the walls. Agree, not a very inspiring sight!

Let's imagine a living room with an area of 30 square meters with two windows. Using a standard heating system, a convector would need to be placed under each window. In the case of gas convectors, this option does not work. We will need to install one convector with increased power in a certain place on the external wall of the room, where there would be optimal conditions for supplying gas there and making a duct for exhaust gases. With this installation there will be no temperature balance in the room. It will be hot in one corner and cold in the opposite. For comfort, you need to place another low-power convector under each window, which immediately doubles the cost of the entire system and the aesthetics of the room. We conclude that this option is inferior to a conventional water heating system.

The gas convector has low inertia. In other words, it heats up very quickly and cools down at the same speed, which can be considered both a plus and a minus, it all depends on how the device is used. In a residential area, of course, this negatively affects the comfort of the temperature regime, but for a garage, workshop or shed, quick heating is a definite plus.

There is one more nuance in a gas convector, which can, in a certain case, be considered a plus or a minus. It has a combustion chamber in which the gas, burning, heats a certain body and a chamber, which then heats the air. For a long service life of the convector, it must use steel that is resistant to fading. It’s good if it uses just such a special steel. But in this case it will not be cheap at all. If it uses cheap steel, then the convector will very quickly fail due to corrosion, burnout, etc. Now, if in a convector the combustion chamber is made of 10 mm cast iron, then such a device will practically last forever.

Pros and cons of gas convection heating

The production of heating appliances is developing due to the demand for gas equipment.

Among the main advantages noted by users are the following:

Economic benefit . The purchase and installation of a gas unit is more expensive than its electric counterpart, but subsequently you will have to pay much less for fuel consumption. Especially if the source is natural gas.
Versatility . Gas appliances are designed to connect both natural and bottled gas. The ability to run on propane will come in handy for owners whose homes are not supplied with mains fuel.
Lack of coolant . There is no need to install a pipeline, and in winter, during downtime, there is no risk of liquid freezing. Local convection heating is convenient for garages and small cottages.
Environmental friendliness . Devices with a coaxial pipe and a closed combustion chamber do not burn oxygen from living spaces.

But there are also some disadvantages. For example, not everyone likes the dimensions of heating devices - more compact electric analogues can be found on sale. For residential premises, it is preferable to buy wall-mounted models that take up less usable space.

If a room in the house is not thermally insulated enough and has several windows or doors to adjacent rooms, it is difficult to provide full heating - there will also be cold areas

The steel heat exchanger, typical of inexpensive models, cools quickly, thereby reducing heating efficiency.

Features of use

The operating principle of the device is based on the physical phenomenon of convection. Streams of cold air penetrate through the lower grilles, heat up from the heat exchanger and rise to the ceiling. Constantly circulating air quickly heats the room. When installing convectors, there is no need to install heating pipes in the apartment.

Several convectors are installed in a large house. A main gas pipeline must be connected to each of them. One device heats a room with a volume of up to 130 cubic meters. It maintains a given temperature regime with a minimum gas flow rate - from 0.22 to 0.48 m3/hour, depending on the model.

The efficiency of the devices reaches 88%. In comparison, gas boilers operate with efficiency of up to 98%. The performance is improved for devices with fans, but at the same time the noise level in the room increases. When heating and cooling, steel convectors emit a characteristic crackling sound (the metal expands or contracts). Cast iron casings do not produce any sounds.

Gas appliances come in two types: wall-mounted and floor-mounted, fireplace type. They are fastened in the same way, have a common principle of operation, but the latter are larger in size.

How to install a gas convector

After you have chosen and purchased the heater, you can proceed to preparing the installation. Make sure you have the following tools and materials:

Tools necessary for installing a gas convector.

When everything is ready, you need to choose the location of the convector. For the correct selection, use GOST. The latter requires mandatory installation of the heater under the window. Don’t be lazy in the process to try on the device to the chosen place, and also make markings after that. The next stage is preparing the premises. The room must be covered, as during work a large amount of dust will appear.
