Gas convectors are devices used for heating rooms and running on gas fuel. Their distinctive qualities- economical and noise-free. Gas convectors are ideal for country houses and apartments. Let's take a closer look at the features of their operation, the criteria for choosing gas convectors, and also how ordinary users respond to the operation of these devices.
Features of gas convectors
To operate gas convectors, both natural and liquefied gas are used. To change fuel you just need to reconfigure gas valve. Gas convector also used as a main or backup heat source (room temperature can reach up to 38 degrees). Equipment power fluctuates from 2 to 6 kW.
Gas convectors are usually attached to the wall under the window sill. They are equipped with a pipe system that ensures the removal of combustion products and air intake. Installed in gas convectors temperature sensors , allowing you to control the selected temperature regime. In case of interruptions in the gas supply, the gas valve in the convector is activated, which blocks the fuel supply.
The main advantage of gas convectors is efficiency. This device reduces heat loss to zero, thereby allowing you to save on space heating.
Flaw - the need to punch holes in the walls for exhausting the chimney and creating an extensive gas distribution system around the house, in the case of working on main gas.
Choosing a gas convector
First you need decide on the type of fuel:
- natural gas
- liquefied gas
Whichever fuel is more available in the area of your home, we buy that convector. It is also necessary to pay attention for the length of the flue pipe so that its length is no less than the thickness of the wall in which you will make the hole. Of course, if necessary, you can contact a specialist to increase the length of the pipe, but this is an additional cost.
Gas convectors are:
- with fan
- without fan
It is practical to install a convector with a fan in a room where does not require constant heating. But installing a convector with a fan in residential premises is not entirely convenient, since the operation of the convector is accompanied by constant fan noise.
Only specialists should install gas convectors appropriate qualifications. At correct installation and operation in accordance with the instructions, your gas convector will become a profitable, comfortable and safe heater.
Reviews from owners of gas convectors
On January 5, we received the long-awaited convector. For two months we have had beauty here - we don’t need any water or light. This month I have burned only 62 rubles. The first month was longer, of course, while we warmed up the house. And before, the apartment was 15 sq. m., we paid 700-900 rubles a month and there were often interruptions: no light - it’s cold, no water - it’s cold again. Now there are no problems. Great stuff. I would advise everyone to bet. The main thing is that quickly installed, low costs. There is nothing complicated - one hole was punched, there are no pipes and the hood is under the window. All. Exhausts don't bother me. We open the window - no exhaust. Very satisfied.

I bought Zhytomyr-5 KNS two months ago for a room of 23 square meters. m. and in the bedroom there is an AGOK-2.5 convector with a cast iron heat exchanger. If you want to sleep in silence, don’t regret it, add 1500-1800 rubles and buy it with a cast iron heat exchanger. It will work silently and generate better heat.

I bought a gas convector Uzhgorod AKOG-4-SP 2 years ago - Heats the room perfectly, but the body has turned yellow. But this did not affect the work.

I use convectors DEMRAD NGS-30 without fan on garden house. 2 rooms of 16 sq. m. Built as a summer house with light insulation. At first I just wanted to install a stove, but in 2008 we installed main gas, so I installed convectors. I didn’t know anything about them then. I just read and chose non-volatile ones, because there is no need to do grounding. And the price is also beautiful - 6500 rubles. to 2008. Today the price has increased slightly for convectors. Well, about heating. Convectors are all included heating season. The regulator is set to a minimum of +13, works at Idling. If I come, I set it to 4. After 3 hours, you can walk around in a shirt. But the house warms up completely after about 12 hours. The insulation in the house, of course, is not sufficient, you still need to insulate it - this will pay off. Now I I spend 500-600 cubic meters of gas per season. I connected it directly to the main line, so I won’t say anything about power from the cylinders. It seems to me that for houses with two or three rooms, convectors are very profitable. Well, if the house is larger, then it is better to install a boiler.
Pavlyukovich Kirill
In the fall, we finally installed gas and installed convectors. For 2006−2007 heating season consumed 1024 cubic meters of gas(area 70 sq. m.). I did not exceed the minimum limits. For gas I pay 39 kopecks per cubic meter. in total I paid only 399 hryvnia 36 kopecks. Funny. And the temperature in the house is always +26 degrees. There are no questions at all regarding the work. The air is dried just like the radiators, I keep each room at a certain temperature (I like it cooler in the bedroom), and in difficult times I only heat the room, not the whole house. Yes, and they work on the “set it and forget it” principle. And the interior has been decorated.
Shumov Alexey, Lutsk
In my opinion - for country house just right. I dismantled my Demrad a month ago after two years of use, that’s a fact. In autumn and spring, he heated my dacha simply superbly. I left it on for several days (the passage through the wall needed to be done correctly). Only my house is larger and the unit cannot warm it up quickly in winter. I'll put it in the attic, where the area is smaller.
Karasev Ivan, Omsk
There is a need for gas convectors. They are used by people living in Arkhangelsk, Tyumen and other regions of Russia. And most of Europe. There the topic is spelled out in all the details and subtleties. A convector is no more dangerous than a gas boiler. Fence batteries for rooms up to 50 sq. m. there is no point. Convector not afraid of defrosting- these are its certain advantages. The disadvantages are the need to make an exhaust hole in the wall and a gas supply outside around the house. Installation and maintenance from an economic point of view will cost less than a boiler.
Bugaev Vladimir Leonidovich
If your non-permanent home is located in locality- village, regional center or agricultural town, then the best way no heating. You can come to cold house and turn on the stove, wait long and patiently, or you can come to a warm one with a convector installed. Just look carefully at the technical passport to see which areas of the house are residential. Only in non-residential premises- hallway, kitchen, pantry - You can install pipes indoors.

Video review of the operation of the gas convector
Various heating devices and devices are used to heat rooms. Gas convectors are considered reliable and practical in operation. The heat that comes from this device is transferred into the room as quickly as possible. These convectors can be used to equip a house with either a centralized or an autonomous heating system.
Operating principle of a gas converter
Heat enters the room due to convection of the heating device, when warm air flows from the hot heater. The gas convector is equipped with a special sealed combustion chamber; it is the surface of this chamber that heats up during gas combustion.
The convection method is based on the fact that warm air that comes from a heat source goes upward. Cold air (which is heavier) falls down the room and, in contact with the convector, heats up and goes up. Yes, due to constant circulation air flow, the whole room warms up.
To increase the power of a gas convector and maximally heat a room of any size with natural gas, some devices install a fan heater. It accelerates convection in forced mode, and this, accordingly, significantly reduces the time to heat the room to the desired temperature.
Features of choosing a gas converter
When choosing the required model, you need to consider certain conditions operation, study reviews, find out the price, know the area of the room And highest temperature for heating. Detailed description everyone technical properties and criteria will help you cope with the task of purchasing the optimally best gas convector.
Like all heating devices, gas convectors have their own characteristics that need to be taken into account and understand how to choose the right convector for your home:
- Circulation method. The presence or absence of a fan heater.
- Thermal power.
- Installation option. Floor or wall.
- Extraction method.
- Heat exchanger material. Steel or cast iron.
Floor or wall gas converters
Taking into account the criterion of saving space and working conditions, they are considered more practical and suitable wall gas convectors. They do not take up very much space and, as a rule, are installed on the wall near the window, which provides additional thermal curtain between the room and the cold window.
But these devices should be quite light and not create a large load on the wall. Gas wall convectors are limited in thermal performance to 10 kilowatts.
If you need to heat a large number of areas, then use a more powerful floor gas equipment . These devices create a greater amount of thermal energy, but also have much larger dimensions, as well as significant weight, they need a reliable and stable base.
The price of floor-standing and wall-mounted devices is approximately the same with similar equipment capacities.
Thermal power
When choosing a gas convector you need to take into account size of heated room. It is this parameter that is considered fundamental when calculating the efficiency of a gas convector. There are a number of methods for calculating the required power.
The main calculation takes place taking into account this rule: for every 10 square meters the room will consume 1 kilowatt of heat.
This is universal formula, it is most suitable for standard premises with a ceiling height of no more than three meters, the usual arrangement of doors and windows and good insulation.
If more careful calculations are needed in poorly insulated or non-standard rooms, then you need to contact professionals.
Gas converter heat exchanger material
The operation of the convector is based on the combustion of gas in the thermal chamber of the equipment, and the heat exchanger inside is subjected to powerful thermal effects; burnout of the heat exchanger quickly disables the device. That is, of course, the material of manufacture simply must be most stable and durable.
In this case, the clear leader is cast iron. The cast iron heat exchanger is thermally stable; the service life of these gas convectors is more than 50 years.
Another advantage of a cast iron heat exchanger is slowest cooling And uniform distribution heat. The disadvantage, judging by the reviews, is heavy weight and, high price.
Steel convectors with a heat exchanger, cheaper and lighter than cast iron. But when purchasing, you need to pay attention to the quality of the steel; this gas convector can last at least 30 years.
Closed or open combustion chamber
A simple exhaust hood is based on taking air from the house and removing combustion products into a vertical chimney.
The simplest gas convectors are designed according to this principle; the disadvantages of this device are obvious. This burning the air in the room, the need for the converter to have good ventilation and the creation of a complex chimney that passes through the roof and ceilings.
The advantages of these devices are: the price is a little less, unlike other devices with the same parameters.
Convectors with closed camera combustion. Here the draft is supported by a fan built into the chimney.
With this equipment option a coaxial chimney is installed, through the internal pipeline of which products exit gas exhaust, and according to the inter-pipe distance, air is taken into the combustion chamber.
Forced operation of the smoke exhaust occurs using an installed centrifugal fan. This can be done by a convector with a volatile and closed combustion chamber; it is much simpler, safer and more practical to install.
Fan heater installation
The installed fan heater ensures fast and uniform heating of the entire house. Another very important factor- this is the supply of air to the heat exchanger, this entails forced cooling of the hot body.
This creates some protective measures from constant heating, thereby extending the service life of the material from which the heat exchanger is made. This cooling is all the more valuable in devices with increased thermal power (thousands of kilowatts).
What gas should I use?
Initially, gas convectors are designed for connection to a central gas pipeline. Thus, it seems that they only run on natural gas.
But when using special kit adapter, gas convectors quickly switch to operating mode on liquefied gas. Certain brands of convector models were initially designed with the possibility of switching to liquefied or bottled gas.
Features of working on natural gas:
- Clear technical requirements to the operating and installation conditions of the equipment. It is advisable to entrust the installation work to professionals, regardless of the possibility of doing it yourself. Moreover, you need to strictly follow the requirements and safety measures.
- You won't be able to save much: price natural gas similar to the price of electricity per 1 kilowatt of electricity.
Installation of a gas convector is justified and is a great way out from the situation in those regions where there are no centralized gas lines, and the supply of electricity occurs with great interruptions or is completely absent.
Advantages of a gas convector
But the savings are achieved due to the fact that only 0.1 cubic meter of gas is needed to produce one kilowatt of thermal power. All these statements are based only upon connection gas device to the main gas pipeline and the use of natural gas.
Disadvantages of gas convector design
Dimensions. This indicator is significantly lower for a gas convector. These devices are not very compact, especially floor models. Taking into account the need to increase the thermal power greatly size and weight increase equipment.
Selecting several low-power convectors for a room with many windows. If there are several windows in the room, then when one convector is operating, the air in the corners of the room may be cold. To do this, you will need to install a convector under each window, which is not always economically rational.
Low inertia. Conventional metal gas convectors quickly cool down and heat up. This parameter is not always a negative advantage; it all depends on the type of heated housing.
Lack of mobility and the need to arrange a hole for the chimney in the wall are also a disadvantage of this type of heating device.
Gas convectors, used to heat individual rooms and rooms using natural gas, are considered economical heating systems. But if it is necessary to heat several rooms or large areas they lose to more efficient and economical boilers heating with an autonomous system.
On December 30, we installed such a long-awaited convector. In just a few months we have had beauty here - we have no water, we don’t need light. In the first month I spent about 150 rubles. The first month, naturally, took longer to warm up your house.
And before that, the apartment was 20 square meters. m., we paid 800-1000 rubles a month and there were often interruptions: no light - it’s cold here, no water - it’s cold again. And now, there are no problems. Great stuff. I would recommend everyone to install it.
The main thing is that it is quickly installed, the costs are low. Nothing complicated - one hole was made, no pipes, and the hood is located near the window. All. The exhaust all goes there. We open the window - and that’s it. I'm happy, I recommend it to everyone.
Max. Krivoy Rog
For a room measuring 80 sq. m. (room made of permanent formwork, warm ceilings 2.80 m) in severe frosts, 60 liters of gas in a cylinder is enough for a week. No electricity needed at all! Really beautiful and warm. I advise everyone.
Vlad. Moscow
I purchased it three months ago, I read reviews of the gas convector, Zhitomir 5 KNS for a room of 25 sq. m. m. and in the bedroom there is an AGOK 2.5 convector with a cast iron heat exchanger. If you want to sleep in silence, do not regret it, add a couple of thousand rubles and choose one with a cast iron heat exchanger. It will work quietly and warmly much better.
Andrey. Voronezh
A variety of heating devices for residential premises allows citizens to select devices that satisfy the maximum number of individual requirements from heating systems. Somewhere acceptable performance characteristics is to control all processes from one point, for example, a boiler room, but for some it is more convenient to regulate the temperature and fuel consumption in each room individually.
In the second case, a gas heating convector is most suitable for operation. This device uses known school course laws of physics when hot air rises, and the cold one is located below.
System operation
It is possible to achieve an increase in room temperature using the convection method. Warm air is distributed from installed heater. IN gas converter The heating system has a small combustion chamber built into it. It is sealed from other elements of the unit. Its outer surface has elevated temperature. Touching it, the air passes through the internal cavity and, warming up, goes up.

In parallel with the departure of the heated portion of gas, a new volume of cold portion is pulled up from below. This creates heat circulation in the room.
It will be possible to increase the efficiency of a household heat converter by installing it on the path warm flow blower fan. Due to forced convection the interval between the device entering operating mode will be significantly reduced.
Right choice
Having understood how a gas convector works, it is worth paying attention to the main criteria by which the device is selected. They must be taken into account when choosing the most suitable convector for your home:
- installation option (floor or wall);
- output power characteristics (low power produces little heat, and excessive power makes the device excessively expensive);
- materials used (steel is lighter, and cast iron is more durable);
- type of hood ( geometric parameters);
- circulation method (forced with a fan heater or natural).
When choosing a heating gas convector, the maximum number of parameters is taken into account.

Wall mounting or mobile installation
Depending on the desired effect, gas heating convectors are selected in the form attachments on the wall or mobile installation in any convenient location. In most cases, they are hung under the window. Thanks to this design solution an additional curtain of warm air is provided. The weight of such devices must be able to withstand any surface.
For suspended devices there is a power limit of 10 kW.
If you need to increase the temperature for a while, you can set floor convector for heating rooms. Their intended design capacity is higher than that of their analogues. However, they have the following disadvantages:
- have a large mass;
- their dimensions are larger than suspended models;
- To install a mobile heating gas convector, you need a flat, solid platform.
The cost of pendant models is approximately comparable to mobile models with equal power.
Unit power
A high-quality gas convector for a summer house or private home is selected based on the area that needs to be heated. This parameter is basic when carrying out calculations. There are a few effective techniques, which are used to calculate the required power.
In most cases, a simplified version is used, in which approximately 100 W of thermal power is required to heat one square meter of area. This approach will be typical for rooms with a ceiling of up to 3 m. The following conditions are met:
- the walls are insulated;
- The windows are equipped with thermal insulating spectro-packs;
- The doors are well insulated.
The output power value produced by gas heating convectors is indicated in the device passport.
Combustion chamber shape
Modern gas convectors using natural gas are equipped with a combustion chamber. It burns gas received from outside. Due to high temperature exposure for long period During operation, the camera can burn out and quickly fail. The use of reliable heat-resistant material helps solve this problem. Cast iron has proven its effectiveness in this area.
Manufacturers provide devices with a cast iron chamber with a half-century operating guarantee. Positive qualities are also inertness during temperature drops and uniform heat distribution throughout the heat exchanger.
Cast iron units are more expensive compared to steel counterparts and due to the thickness of the walls they weigh much more.
Although steel weighs less, its service life is limited to 20 years.
The hood captures air from the room for the combustion process, and decomposition products are discharged through the built-in chimney. The obvious disadvantage of this design is the intense burning of oxygen in the room. The problem is compensated by the lower cost of the device, unlike its analogues.
High-quality gas convectors for a summer house or home are equipped with a closed combustion chamber. Inside, the draft is provided by a fan mounted in the chimney cavity.
For efficient work installation will be required coaxial chimney, through which combustion products will be removed. The draft is provided by a fan. Although the design becomes dependent on the availability of electricity, it provides advantages in the form safe operation, practical installation and ease of operation.
Built-in fan heater
The room is heated quickly and evenly thanks to the fan heater. Its additional positive function is to ensure air flow to the heat exchanger, while simultaneously cooling the body of the device. This engineering move extends the service life of the convector. This quality is especially important for powerful devices.
What gas is used
Initially, it was believed that gas convectors were designed exclusively for centralized gas supply through a main line. Today, models appear on the market that can reproduce heat and based on liquefied gas. Moreover, there are special transition kits on sale, with the help of which even previous gas convectors quickly and very easily switch to operating mode from bottled gas (liquefied). No problems have been identified during the transition, but if you do not want to take risks, it is better to immediately choose models designed for an alternative gas supply.

IN last years A heating device such as a gas convector is gaining increasing popularity. Despite the absence of complex electronics and innovative technologies, it perfectly combines such qualities as high efficiency and economy, ease of operation and relatively low cost.
A household gas heater is an excellent heating method country house, greenhouses or production premises. Gas convector is better than any other heating device suitable for rooms where constant heating is not required, as it is capable of as soon as possible warm up even enough large building. The fuel for a gas convector is, as is easy to understand from its name, natural gas, which is one of the cheapest types of fuel. In addition, this inexpensive fuel is used quite sparingly - after all, the efficiency of a gas convector reaches 90%. As a result, the cost of heating premises using convectors is approximately an order of magnitude lower than heating using electricity, and much lower than using boiler equipment.
There is only one question left - how to choose a gas convector, what is the difference between the models on the market and what characteristics should you pay attention to. To answer this question, you need to understand how this device works.
Operating principle
Natural gas is supplied to the steel or cast iron combustion chamber, which, when burned, heats the heat exchanger. Cold air entering the convector from below quickly heats up as a result of contact with a hot heat exchanger and rises.
Although air circulation occurs very quickly, nevertheless, in some convector models an electric fan is also installed, which can be useful when you need to warm up the room as quickly as possible. Gas combustion products are removed from the room through the same pipe through which fresh air enters. This is achieved through the use of the so-called coaxial chimney - a two-layer pipe in which the outer layer supplies the room with outside air
, and hot combustion products are removed through an internal chimney isolated from the wall.
Criterias of choice To figure out how to choose a gas convector, you must first find out whether it is needed? Please note that this device is a direct competitor gas boiler . A boiler will be preferable when you need to heat a fairly large building with big amount
premises (more than four), in this case the costs of arranging a room for a boiler room and performing expensive and labor-intensive piping will be justified. The convector is better suited for a house or other building that has small sizes , where you do not have to allocate a separate room for the boiler room. Another advantage in favor of a convector may be the non-permanent residence in the house - it is not subject to freezing, and upon startup it immediately supplies warm air
into the room, quickly warming it up. This heating device has practically no alternative when used as a backup heating source in regions with frequent power outages. To calculate the required power of a gas convector, use standard formula – one kilowatt for every ten square meters of room area (with a ceiling height of up to three meters). To the one obtained by this formula One kilowatt should be added to compensate for possible heat losses due to ventilation of the room, opening doors, etc. Do not be afraid that excess power can cause discomfort; almost all models of gas convectors have a thermostat.
When choosing a heat exchanger material, you should consider the following: the most durable are convectors with a combustion chamber made of cast iron. In addition, they provide even heating and have more high efficiency. The disadvantages of such devices include the fact that they are ten kilograms heavier than their counterparts with a steel chamber, significantly more expensive (by about 50%) and are produced in a limited power range (2 - 5 kW). Steel appliances have a power of up to 12 kW, they are cheaper and another advantage is the best appearance, but, as already mentioned, they are less durable.
The type of chimney is also important. It was already mentioned above coaxial pipe. It is only necessary to add that on most models it is telescopic, which makes it easy to adjust its length. Horizontal chimneys have different diameter, depending on the power of the device (12 - 24 cm) and are covered from the outside with a protective and decorative casing, which gives them a rather aesthetic appearance.
If the gas convector is installed in place of the boiler or wood stove, it may make sense to purchase a model with open camera, and use the remaining vertical chimney in the house for it. Such devices are somewhat cheaper than their “closed” counterparts, but require constant supply fresh air and are not suitable for bedrooms.
You should also consider what gas you plan to use in the convector. If this is main gas, then you need to know that its pressure in domestic networks is 130 mm. water Art. Of course, most devices can be adjusted to this value, but it is better to immediately buy a device adapted for our country. When using bottled gas, it is necessary to take into account the cost of a set of nozzles larger diameter(about 10-15$). Sometimes it comes included, but more often it has to be purchased separately. There are inexpensive compact household convectors on the market, designed to operate only from cylinders, which are installed inside the device body. It is better to refuse them, as this design is unsafe.
It is worth paying attention to ease of use - the device is started using a piezoelectric or electrical diagram. The latter is somewhat more convenient, since it produces sparks as long as the button is held, but requires periodic replacement of the AA battery. The presence of a fan speeds up the startup of the system, allowing you to warm up the room faster, but this advantage only appears at the start; most of the time it will most likely be turned off.
Operating Cost Accounting
When using mains gas, heating using a convector is approximately ten times more profitable than electric heating. The use of bottled gas is not as profitable, but can be recommended for creating completely autonomous system heating
As a basic figure for calculating fuel consumption per kilowatt of thermal power, you can take 0.11 m3 of natural gas or 90 grams of liquefied gas.
