Consumers like that LPG or natural gas can be used to operate gas convectors. To change the type of fuel, it will only be necessary to readjust the gas valve. The convector can be used as a backup or main heat source, while the air temperature in the room warms up to 38 ° C.

Buyers emphasize that they like the choice of power, which ranges from 2 to 6 kW. In devices of this type for heating, temperature sensors are usually used, which allow you to monitor the temperature regime. If there are interruptions in the gas supply, the valve that blocks the fuel supply will be triggered.

Device

Gas convector operation diagram
The design of the gas convector is simple to the limit, it includes:

• the combustion chamber;
• gas-burner;
• automation unit (Eurosit);
• a heat exchanger that forms the outside of the combustion chamber;
• coaxial chimney.

The combustion chamber is of a closed type. Air from the street is fed into it and combustion products are discharged there. There are a small number of models of convectors with an open burner, but it is better to bypass such devices, since they quickly burn oxygen into the room and saturate the air with CO2 and other combustion products.

Combustion chamber and heat exchanger material:

• steel;
• cast iron.

The steel chamber is lighter and cheaper. The convector with steel filling is 10-15 kg less in weight than with cast iron. However, even if the manufacturer used special heat-resistant steel, it still burns out over time and the service life of such a device is lower.

The cast iron combustion chamber has an almost unlimited service life, it is sensitive only to sudden changes in temperature. From what microcracks appear in the material. Otherwise, cast iron is resistant to corrosion, does not become thinner under the influence of open fire and has a high heat capacity, which is rather a positive characteristic for a heater.

The convector uses a single-module burner that is simple in shape, providing even combustion over a distributed area. It is important that the flame torch on each nozzle is small, and the gas, mixed with air in a certain proportion, burns out completely without residue.

Gas convectors are designed for the use of natural gas in accordance with GOST 5542, low pressure 1274 Pa. Often, convectors simultaneously support the installation of a liquid gas cylinder, which is supplied through a nozzle and a reducer. Mechanical automation, more often the well-proven EuroSit, is responsible for controlling the gas supply, adjusting the output power and controlling the temperature in the room.

The chimney is presented in the form of a coaxial pipe, in which a branch pipe of a smaller diameter is inserted into a pipe of a larger diameter, forming two separate channels. Combustion products are discharged through the inner channel, and fresh air from the street enters through the gap between the pipes to maintain gas combustion. It is assumed that the convector is installed near a wall adjacent to the street. The chimney immediately goes to the outside of the building through a prepared channel. The shorter the chimney length, the better.

Supercharged

The heat exchanger is heated quickly and actively, its temperature can reach 600 ° C, although more often the area of ​​the heat exchanger is designed so that the convection flow is sufficient to maintain a significantly lower temperature of 60-120 ° C.

One of the options to actively and quickly remove heat from the heat exchanger, and at the same time to quickly warm up the heated room is to use a blower, a fan that can quickly drive a large volume of air through the convector.

This approach is appropriate, for example, for heating a utility room, a production or construction area, a country house or a garage. Where it is mostly cold, and it is necessary, if necessary, to create comfortable conditions for people in a short time. If the convector is used as the main source of heat, then the fan will be partially occupied only at the beginning of the process, until the air heats up, and then turns off and will not be used.

The most compact convectors should be discussed separately. They use the fan constantly. The area of ​​the heat exchanger is reduced to reduce the weight and dimensions of the device, and to achieve the required heat output, a fan is needed to have time to remove heat from the combustion chamber.

Additional benefits

Consumers note efficiency as the main advantage of gas convectors. Heat losses during the operation of this device are minimized, which saves on space heating. However, there are also disadvantages, as one of them, consumers highlight the need to drill the holes that are required to install the chimney system. It will also require the formation of a branched gas distribution around the house, which is true if the equipment will operate from main gas.

Pros and cons of a gas convector

Advantages over the boiler:

1. Air is used as a heat carrier, so no piping is required.
2. High heating rate.
3. The risk of freezing and damage to the heating system is eliminated.
4. Installation cost. It is enough to break through the shaft, fix the device and connect the communications.

Disadvantages:

1. On a large area, you will have to install a convector in each room.
2. An additional boiler is required for hot water supply.
3. The boiler retains heat longer after shutdown and is used for floor heating.
4. The facade of the building will suffer due to the through hole in the wall for the chimney.

The analysis shows that the gas convector is effective in apartments and country houses of a small area, where the organization of hot water heating is impractical.

Which gas-fired convector to choose

View gallery

If you are interested in gas convectors for summer cottages, then you must first decide on the type of fuel, which was discussed above. It is important to consider whether liquefied or natural gas is more profitable in your region. It is also important to pay attention to the length of the gas outlet pipe, because this parameter should not be less than the thickness of the wall where you will make the hole.

When choosing a specific model, it should be borne in mind that some of them have a fan. If you plan to install the convector in a room that does not require constant heating, then it will be more practical to use equipment with a fan, whereas, as for residential-type premises, it is better to purchase a model without a fan, since it will work without making any noise at all.

What gas should be used

Initially, gas convectors are designed to be connected to the central gas pipeline. Thus, one gets the impression that they only run on natural gas.
But when using a special adapter kit, gas convectors quickly switch to operation on liquefied gas. Certain brands of convector models were originally developed with the possibility of switching to liquefied or bottled gas.

Features of work with natural gas:

1. Clear technical requirements for the conditions of operation and installation of equipment.It is advisable to entrust the installation work to professionals, despite the possibility of installing it yourself. Moreover, you need to strictly follow the requirements and security measures.
2. It will not be possible to save a lot: the price of natural gas is similar to the price of electricity in terms of 1 kilowatt of electricity.

Installing a gas convector is justified and is great way out from the situation in those regions in which there are no centralized gas pipelines, and the supply of electricity occurs with great interruptions or is completely absent.

Recommendations for choosing a specific model

If you are considering gas convectors for summer cottages, then you need to pay attention to some models of such equipment. For example, "Zhitomir-5 KNS" will be able to cope with heating a room with an area of ​​23 m2. Additionally, it will be possible to install a convector of the AKOG-2.5 brand in the rooms, which has a cast-iron heat exchanger. This decision must be followed if you want to sleep in silence. However, in this case, you will have to overpay about 1800 rubles.

Quite often in country houses today you can find gas convectors on bottled gas for summer cottages of the "Uzhgorod AKOG-4-SP" type. This option perfectly heats the room, but over time it can lose its attractiveness in appearance. However, consumers emphasize that this does not affect work efficiency in any way.

For owners of suburban real estate who often live in such houses, the DEMRAD NGS-30 gas convector, which does not have a built-in fan, is perfect. Two rooms, each of which has an area of ​​16 m2, it will be able to heat. Gas heaters-convectors for summer cottages are quite often chosen by consumers for the reason that they do not require grounding when connected, in addition, the price also attracts, which is 6500 rubles.

To fully warm up the house, it will be enough to turn on the equipment and leave it. After 12 hours, the house will warm up evenly. For more efficient operation, it is recommended to connect the equipment to the mains, so as not to worry about the need to change cylinders. Owners of houses with three rooms claim that heating with such a convector will be very profitable. But if the house is slightly larger, then it is better to take advantage of the possibility of installing boiler equipment.

Video feedback on the operation of the gas convector

Good day everyone! Here, by popular demand, I decided to create a blog on my country house heating! IF SOMETHING IS WRONG, OR THE OWNERS OF THIS SYSTEM DO NOT AGREE, PLEASE DO NOT BE OFFENSE! Since there is no centralized gas, But there is imported gas in cylinders. I am very glad! Everyone knows very well about the situation. Electric heating in the country is very expensive. Well, maybe not everyone, but still. Well, I thought for a long time talking with people and came to the conclusion to install gas heating for myself. But then the question arose of what to set myself and how it would behave (Tolya gas boiler or gas Convector) As a result, I stopped at GAS CONVECTORS. Yes, for each convector there is a pipe that goes outside through the wall, so they hang on the wall. WHY? First and foremost GAS CONSUMPTION (The gas convector consumes from 0.200 to 0.250 grams per hour) While (the GAS BOILER consumes approximately and this is at least 1.3 liters per hour) I want to dispel strange thoughts that sometimes come into my head , Below in the photo they are hanging on the wall Gas convectors pipes go out into the street (for air intake and the exit of burnt gases) So Gentlemen, if anyone does not know the GAS CONVECTOR WORKS LIKE A BOILER, it has 7 operating modes, a handle from 1 to 7 (That is it turns on and off when a certain temperature is reached and does not burn constantly) it also contains a temperature sensor and Italian gas equipment.As you can see on the plan, I have 2 pieces, one in the kitchen and the second in the room. (The room was replaced with a new one, since the previous gas convector was rented for testing) and then I was satisfied. The one in the kitchen is KARMA. I really liked the 3 kW convector (this is a Czech company) for the workmanship. The closed combustion chamber. Steel heat exchanger. The heated area is not more than 35 m2 The one in the room is the KORDI company. The convector 2.3 kW (This is already Ukraine) is a closed combustion chamber, since it is smaller and eats less gas. Steel heat exchanger. Heated area no more than 23 m2 Further, according to the plan, in room number 1 there is an electric convector marked (BlueM) with a capacity of about 600 watts, since I did not dare to install another gas convector. And this was enough and enough for me. to maintain the temperature in the room. there is still a mess so I did not take a picture.

On the plan is the location of (Red) gas convectors and cylinders. (RED) Lines These are the so-called (Vremyanka) gas hoses that run along the street. In the kitchen (BLUE) the Gas stove is paralleled with the Gas convector in the kitchen. (here, of course, the gas leaves faster, but not much) Where there are 4 red circles, it will eventually be heated by the host unit for gas cylinders and from there the wiring will go to the outside of the house with gas plastic pipes.

Feedback on some selection criteria

View gallery

Considering gas convectors for summer cottages, it is necessary to pay attention to a number of criteria. For example, to determine the required power, a formula is used that says that a kilowatt of power will be required for every 10 m2 of floor space. This is true if the ceiling height does not exceed 3 m. Consumers advise to add 1 kW to the calculated power, which will be required so that the equipment does not work for wear and tear, and the owners have the opportunity to ventilate the premises by opening windows and doors.

Gas heaters for summer cottages (convectors) must also be selected taking into account the material of the heat exchanger. The most durable, according to buyers, are devices with cast iron combustion chambers. They allow you to achieve uniform heating and have a higher efficiency.

Consumers also see the disadvantages of such devices, which are expressed in heavy weight compared to counterparts with steel chambers. Among other things, such a unit will cost about 50% more, and devices are produced in a fairly limited power range, varying from 2 to 5 kW.

If you prefer a steel appliance, then its power can be equal to 12 kW. Consumers say such heating appliances look better, are cheaper, but less durable. It is impossible to ignore the type of chimney when choosing. There are many models on sale with a telescopic coaxial pipe, which makes it easy to adjust the length. In the case of horizontal chimneys, they can have different diameters, depending on the power of the device. Consumers are advised to choose units that have a chimney with a decorative outer casing, because this gives the equipment an aesthetic appearance.

Reviews of some models of gas convectors: Alpine air NGS-30F

The aforementioned gas convector for a summer residence, the reviews of which are the most positive, costs 25,400 rubles. It has a cast iron heat exchanger and ensures high quality continuous operation. A fan is built into the case, which, according to buyers, helps to accelerate the spread of heat.

The work is controlled by a mechanical system. Customers love that the dimensions of the device are quite compact and equal to 630 x 230 x 460 mm. The equipment weighs only 27 kg, while the power is 3.75 kW.

Advantages of a gas convector

1. Economic indicator. The price of an electric converter is much cheaper.But, as the reviews show, the advantage of gas convectors is the low cost of operation. For example, popular heating devices with cast-iron heat exchangers and a capacity of approximately 3 kilowatts are half the price of electric ones with the same characteristics.
2. Liquefied gas converter operation. It is very easy to convert the gas convector to balloon equipment. This allows the use of these heating devices in regions where there is no electricity or it is supplied with some interruptions. But in economic terms, convectors on a cylinder or liquefied gas are also economically imperfect, like electrical equipment.
3. There is no coolant. This is a noticeable advantage in the absence of running water in houses where it is planned to connect heating devices. It is also a great factor if in the winter season it is necessary to leave the house for a long time - the water in the convector will not freeze, because there is simply no water here. This is a great option, for example, for utility rooms, garages, summer cottages.
4. Environmental Safety. The gas convector does not burn oxygen into the room and is safe if all operating rules are followed.
5. Possibility of temperature control. In gas convectors, you can easily set the desired temperature regime and correct it.
6. But this difference is quickly bridged during operation. Simply by calculations, the cost of heating the same area of ​​the house when using natural gas is often 15 times less than when connected to electricity. The price of a kilowatt of electricity and a cubic meter of gas is approximately the same.

But the savings are achieved due to the fact that only 0.1 cubic meters of gas is needed to produce one kilowatt of thermal power. All these statements are justified only when the gas device is connected to the main gas pipeline and natural gas is used.

If you are interested in gas convectors for a summer residence, which one is better, the reviews will allow you to understand. Among others, consumers choose the model that was mentioned in the subheading above. It is used to heat various premises. Their area can reach 96 m2. Consumers emphasize that this equipment has stable legs, and you can observe the burning of the flame through a window made of heat-resistant glass.

The thermostat of this device is mechanical, which indicates its durability. But this is not a complete list of advantages, among others it should be highlighted:

• ease of management;
• vertical chimney;
• open combustion chamber;
• piezo ignition;
• insignificant gas consumption, which is 1.12 m3 / h.
