In addition to all these advantages, the compensation air heater is the most economical means of space heating. How is this possible? It's really very simple.
The direct heating system releases 100% of its heat into the air stream. Systems with indirect heating always have an exhaust or ventilation pipe, which removes hot combustion gases from the building into the atmosphere.
The air heater has an initial peak efficiency of about 56%, as approximately 20% of the fuel is lost to the flue gases and additional fuel is lost to the heat exchanger, which is about 70% of the efficiency of the new device. The heat exchanger fails over time, and the efficiency level can drop to 40 - 50% of the total efficiency.
The air heater is not only inefficient, it cannot provide a uniform temperature because it depends on cold air infiltration for combustion. The combustion process requires approximately 10 parts atmospheric air 1 part natural gas. There are approximately 1,000 British thermal units (btu) per cubic foot of natural gas. A typical building can lose about 3,000,000 btu/hr in normal heat loss. This means that the heaters will consume 3,000 cubic feet of combustion air every hour. This infiltrating air must be heated for the combustion process, therefore it increases the normal infiltration load of the room. The cost of combustion air alone heating appliances is about $0.95/hour.
Unlike air heaters, the make-up air heater does not bring cold combustion air into the building. It also does not draw out heated air. In a compressed atmosphere, the temperature is much more uniform. The make-up air heater does not use a heat exchanger and does not extract or supply cold air to the facility. The gas burner works according to demand and its efficiency approaches 100%. All heat received as a result of combustion of fuel comes directly to the room. Natural gas contains 8% water. During combustion, natural gas generates "sensible/sensible" heat, which raises the room temperature. The water present in the gas generates "latent heat" that provides humidification in the plant. When using an air heater, latent heat is lost in the chimney.
Without a make-up air heater, the natural force of the wind combines with the mechanical exhaust of the building and creates a situation in which cold air enters the room and warm air leaves it. Cold air accumulates near the floor, and warm air rises to the ceiling. Wasted energy collects near the ceiling while workers get cold feet. All burners respond to drafts of cold air at floor level by burning more intensely to compensate for cold air intrusion.
Positive pressure from the make-up air heater provides controlled displacement ventilation. The building still breathes, but now the air inside is fresher and the temperature is even. Fresh air from the make-up air heater pushes stale air and pollutants out. The volume of displaced air is controlled. Exhaust systems in washers and vulcanizing ovens, they operate at specified volumes, without annoying burner extinctions or back draft.
The occurrence of a wind tunnel passing through the equipment, which can occur in air heaters, is excluded. The cost is 20 - 40% lower than with indirect air heating.
Infiltration is the cause of strong temperature stratification. The floor is very cold, especially near the doors and in areas that are poorly insulated from the outside. Air heaters, often used for space heating, will run continuously but will never raise the temperature in cold areas to an acceptable level. Air heaters get their combustion air from cracks in the walls of a building. Since cold air constantly enters through the cracks, there is no possibility that this room will warm up. The heated air from the air heater rises to the ceiling along with the heat generated by the curing ovens and the sink. The temperature at the floor can be around 45°F, while at the ceiling around 120°F (5° - 49°C) and higher. The air heater continues to work in a vain effort to raise the air temperature at floor level to a comfortable value. Cold air continues to infiltrate, BTUs being consumed and lost as temperatures rise and cold air infiltrates.
Thus, a directly heated make-up air heater is more efficient than an air heater. Combustion air enters the heater, heats up to a predetermined value and is blown into the room for efficient energy transfer. Since the air in a building is compressed, heat is distributed through it much more evenly. Those 120°F of air that was lost under the ceiling is now distributed throughout the facility, improving overall comfort. Unlike an air heater, which allows cold air to constantly enter the room, the compensation air heater takes in only the amount of outside air that is needed to meet the needs of the room, raises the temperature to the set value and distributes it evenly throughout the building. The burner modulates to produce just what is needed, no more and no less.
A gas air heater is a device designed to heat the air in a room. Today, this device has been widely used in livestock and poultry factories that require a certain temperature regime, however, today they are often used in residential buildings. The second unofficial name of this heating device is a gas stove. It is worth noting that the air heater is powered by natural gas, which gives it the advantage of minimal inertia, from which the heat that has arisen from the burnt gas quickly spreads throughout the room, thereby heating the room in a short time. The rate of heating in a room is also affected by the power of the gas heat pump.
The air heater consists of several parts, this is a casing, a heat exchanger, a heat exchanger, a multi-speed fan and a smoke exhaust fan, gas valve, as well as a heat and noise insulator. The principle of operation is very simple.
Air is supplied through the fan to the heat exchanger, then, thanks to the gas burner, it heats up and enters the heat exchanger, and only then it enters the room and heats the room. Although the device generates carbon monoxide, it is not dangerous, because this gas leaves through a special chimney.
The choice of such an air heater today is not an easy task, because on the market heating technology there is a wide variety of models gas ovens, differing in the principle of operation, functions and capacities.
First of all, you need to take into account the area of \u200b\u200bthe room. When choosing an air heater for large rooms, you should pay attention to devices with a power of 750-2500 kW, and for a smaller area, a power of less than 750 kW is suitable.
It is also necessary to take into account the presence of gaps in doors, windows and walls, since there is a high probability of heat loss through them, which is directly related to saving money.
By the way, there are 2 classes of gas stoves, premium and economy, such air heaters differ in price and brand of the manufacturer. There are also economical thermal furnaces that can reduce up to 75% of the energy expended when heating a room. It is worth paying attention to the sound insulation of such an air heater, as excessive noise can bring discomfort.
The most efficient and economical of all air heating systems is just gas. Because due to the high efficiency thermal device, due to the low gas waste rate, the cash costs of installing such a system will pay off quickly. Even the absence of a central gas supply will not interfere with its use.
In summary, it should also be noted that gas air heaters are simple designs, and most importantly, reliable, which is so necessary on cold winter days in many industrial workshops and residential premises. By purchasing gas air heater, you can confidently trust him not only with your business, but also with your home.

Hot mix heat exchanger
The thermomechanical load range of the plate is from 0.5 to 1.5 m and the "long" thermal circuit will cover a large load volume, up to 70 m 3 /h in the case of a single-phase solution - this means that all connections will be at the head. This will ensure that service and pipe work can be carried out easily and, in the event of dismantling the heat exchanger, there will be no need to dismantle the pipes. Heat transfer becomes possible when the warm medium transfers energy through the thin, high efficiency plates between the channels and delivers it to the cold antagonistic medium without mixing. Counterflow creates optimum efficiency. plates, as well entrance structure allows easy and efficient CIP cleaning (washing) of all flow surfaces.
Corrugated herringbone surface provides turbulent flow of the total effective area. In addition, this surface allows "metal" contact between the plates, and together with the locking device on the seal, the plate pack is easy to assemble. The plate pack is safely located between the movable and fixed frame supports.

The gas heater is autonomous non-centralized(as opposed to central heating with a boiler) heating system.
In it, the energy released during the combustion of natural gas is used to heat the premises.
Externally, this device looks like casing, with a gas burner installed in it and a heat dissipation panel, which is usually made of ceramics or metal alloys.
The gas cylinder can be built into the body of the device, but it is also possible to connect to the gas line.
Gas heaters for apartment and private houses
Advantages of gas heaters:
- Reliability. These heaters are simple in design, and there is no chance of burnout, as is the case with electric heaters on heating elements.
- High efficiency. Combustion of fuel directly at the place of heating allows reaching values up to 80%.
autonomy, independence from power supply. Many of these devices can operate on both liquefied and natural gas.
Therefore, even if the main gas supply is turned off or it is impossible to connect to it, the device can always be connected to a portable gas cylinder and stay warm.
Performance classification
Depending on the version, the following types of gas heaters are distinguished.
Portable balloons
As a rule, they are made in the form of a body with gas equipment and space for fixing the cylinder (there are also models with the connection of the cylinder through a hose). Sizes can vary from miniature for heating tents on hikes up to overall and powerful, for heating large rooms.
Powerful models, due to their size, are equipped with wheels for ease of transportation. On the body of the device there is an ignition button and a combustion intensity regulator.
Portable gas heaters work only on bottled gas.
Exists two types of gas: natural and liquefied(may consist of both natural and various mixtures, for example, propane-butane). First view- is supplied along the highways and used in stationary installations.
Liquefied- gas in liquid state, it has b about higher density and pumped into cylinders, so it is more convenient for portable use. A device designed only for natural gas will not work on liquefied gas.
Heating devices of this type are used in utility rooms, in garages, on industrial facilities for temporary heating of houses, at outdoor events, widespread use in hiking: in cases where the room small and constant heating is not required.
Due to the specifics of the application, portable gas convectors are equipped with security systems, which stop the operation of the device when the heater overturns, there is no flame or low gas pressure.
Stationary
Heating appliances for fixed installation are usually produced in the form flat panels , because they do not have a place to place the cylinder. Equipped with brackets for mounting on walls and ceilings.
They usually run on natural gas, but some models can use LPG bottles.
Important! Such “omnivorousness” is provided either with change of nozzles(for liquefied gas, the spray hole in them is smaller), or special burners, designed for both types of gas.
Stationary heaters can have both an open combustion chamber and a closed one:
- In heaters with closed In the combustion chamber, oxygen for the gas-air mixture is supplied from the street through a coaxial chimney. The latter is a construct "pipe in a pipe". On the inside - combustion products are removed, and on the outside - air enters. Heaters of this type are an order of magnitude safer than the previous ones, they have more high efficiency and do not affect indoor air quality. But installation coaxial chimney is not always possible.
open- not isolated from the room in which the device is used.
The combustion air for the gas comes from the room itself, so for these devices it is necessary to provide high-quality ventilation premises (otherwise, during use, the air will be depleted of oxygen).
A traditional chimney is used to remove combustion products.
Such devices are often used as an alternative to the system central heating, in places where regular heating is needed for a long time: country houses, apartments.

Classification by type of heat transfer
According to the type of heat transfer, the following types of heaters are distinguished.
infrared
In traditional systems, heaters first of all heat the air in the room, which is mixed by convection, evenly distributing the temperature.
This method is rather inert, it takes a long time to establish the desired temperature, since the air has poor thermal conductivity.
In addition, warm air does not at all mean warm objects and, for example, beds in country house can stay cold for a long time even though the room is already hot.
These shortcomings are not infrared heaters. Devices not heat the air, but the objects themselves indoors (furniture, walls, floors) and people in the zone of its action. Objects heated by IR radiation, they themselves become small sources of heat and heat the air, and a person will not be cold immediately from the moment the device is turned on.
Reference! The principle of operation can be compared with the Sun heating the Earth: despite the complete vacuum in space and long distance, electromagnetic infrared radiation from the sun reaches the Earth and is absorbed by objects, turning into thermal energy, which we feel as “temperature outside the window”.
The mechanism for obtaining infrared radiation is as follows: the gas-air mixture enters the ceramic thermal panel, burns inside, heating it up to 800-900 °C. The panel heated to such temperatures becomes a source of infrared thermal radiation.
Infrared gas heaters are used:
Infrared gas heaters operate on both liquefied and natural gas from the main gas pipeline.
Advantages of gas infrared heaters:
- economy. By heating only desired zone rooms and the absence of losses from the heat source to radiators (as in a central heating system with a boiler), you can save up to 50% energy.
- Optimum space heating. When installing a gas infrared device on the ceiling, it effectively heats the floor and lower part rooms that are most comfortable for a person. With convection heating warm air often accumulates under the ceiling, and it is still cold below.
- compactness.
- Fast and directed heating.
- Absence of necessity in the chimney.
- High price compared to gas convectors and electric radiators.
- The need for regular cleaning and calibration, and repairs can cost a pretty penny.
- They burn oxygen in the room, so you need to take care of it ventilation.
Ceramic infrared heater on gas
The radiating element here is a panel of heat-resistant ceramics with many holes. Passing through them, the gas burns out and gives off all the heat to the ceramic panel, which begins to radiate.
Photo 1. Ceramic infrared heater on gas model UK-04, thermal power 3700 W, manufacturer - "Neoclima",
This type of heating devices is also called "light", because due to heating to temperatures of the order 900°C they emit a glow that can create a pleasant atmosphere and harmoniously complement the interior.
Some models are equipped built-in electric fan, which allows you to slightly increase its power, expand the coverage area, accelerate the heating of the room.
Attention! When using such systems for a long time, be sure to provide fresh air supply into the room.
Moreover, most models of ceramic heaters are equipped with carbon dioxide and oxygen sensors, so if there is not enough oxygen in the room, the automation can simply turn them off.
Advantages:
- power;
- directed action;
- lower price compared to catalytic ones.
Flaws:
- a little bit more low efficiency;
- burning oxygen.
Catalytic IR heater
The name of these devices is due to the catalyzation (acceleration) of the gas combustion process.
They consist of a refractory grid (usually steel or ceramic) that is coated substance-catalyst - platinum and similar.
The gas supplied to the grate does not burn in the usual way, but is flamelessly oxidized by oxygen thanks to the catalytic coating of the thermal panel.
The catalyst contributes to the complete combustion of the fuel, hence high efficiency (up to 80%). The combustion temperature of gas in such heaters below 600 °C, therefore sometimes they are called "dark". Glow during operation is almost absent.
Thermal energy mainly also transmitted by infrared radiation, but in catalytic heaters it is more pronounced convection heat transfer, than in "light" ceramic, where almost all the energy is emitted exclusively in the form of IR.
- higher efficiency by optimizing the combustion process;
- less active oxygen burning(ventilation is recommended, but not as critical as with ceramic heaters);
- compactness and lightness.
Cons: power is limited 2.9 kW(against maximum 5 kW for ceramics).
Convector
Unlike infrared, these devices use traditional way heat transfer through air: convection.
The main element in the convector is a metal chamber, at the bottom of which gas-burner. Burning, the gas heats the entire chamber, which gives off heat to the cold air.
When heated, it rises and provides uniform circulation of heat in the room.
All models are equipped with automatic, which monitors the room temperature and controls the gas supply, as well as safety sensors ( CO 2 , gas leaks).
Convector gas heaters are produced only in a stationary version, since a chimney is required for their operation. The chimney can be traditional type (for appliances with an open combustion chamber), and coaxial(when closed chamber).
Reference! For convectors with open chamber oxygen comes from the room, so they need ventilation. Devices with a camera closed types are devoid of this drawback, the gas combustion process is completely isolated from the premises and takes place, in fact, on the street.
The heat exchanger chamber in convector heaters is made of steel or cast iron. Cast iron is more expensive and heavier, but more durable ( service life up to 50 years), has a significant heat capacity (gives off heat for some time after the burner is turned off), and the efficiency of such devices is higher. Steel chambers are lighter, but their service life is 20 years.
Scope of application - permanent heating of residential and technical premises, country houses.
Advantages of convector type heaters:
- Uniform heating, including large rooms.
- high power (up to 10-12 kW).
- Efficiency up to 92%.
- Autonomy.
- Undemanding to ventilation(for devices with a closed chamber).
Flaws:
- The need for construction chimney.
- Slow heating the room.
- For installation gas convector required in the apartment permission from the gas service.

How to choose the right one for heating your home
Suitable type gas heater depends on the room, the frequency of use and the availability of gas.
As with traditional heating systems, first of all, you need to decide on the heat output of the device.
For typical houses in middle lane roughly estimated as 1 kW per 10 m 2 of area.
For small spaces(up to 20-25 m 2) a catalytic heater is well suited due to its limited power (up to 2.9 kW) and economy of use.
If your room is larger, then suitable choice there will be an infrared device, because its power is higher, up to 5 kW and can warm rooms up to 50 m2. Given the relative localization of this heater, perhaps more the best option will buy several such devices by placing them in different parts rooms to ensure uniform heating.
Give preference to infrared heaters ( catalytic and ceramic) is only worth it if you do not use heating all the time (for example, you come to the dacha for the weekend).
Attention! because of open chamber combustion and interaction with the surrounding air, it is not recommended to use these devices in unventilated rooms with an area of less than 15 m 2.
Otherwise, for continuous heating, use gas convector. This device will evenly heat large rooms without affecting air quality.
If temporary heating is needed (for example, while the stove is flaring up), then portable heaters on liquefied fuel. In addition, pay attention to which gas the selected device runs on.
With constant heating, natural gas from the network should be preferred in order to save yourself the trouble of refilling cylinders.
For the street, only IR heaters with ceramic thermal panel. They are often issued in the form "thermal umbrellas" or pyramids, for vertical installation.
Portable mini ovens infrared type can be used in garages and utility rooms, as well as on camping trips and picnics.
When buying a portable heater, be interested in the presence of protection (from tipping over, gas leaks, excess CO 2), especially if there are small children or animals in the house. Such systems will make the operation of the device absolutely safe.
A device with a built-in balloon: features
When choosing a gas heater with a cylinder, you need to pay attention to some little things.
To work on liquefied gas reducer required, which reduces the pressure of the gas before it enters the burner. Check if it's included.
When placing the cylinder, make sure it is far enough away from the burner to avoid ignition and explosion.
