How air heating devices work
Air heating units are equipment that heats air in large rooms. They are mainly used in industrial, commercial and warehouse premises.
Testing of VOLCANO air heating units
The appearance of the units is usually not very interesting, but there are also models, the body of which is made of plastic. They can be installed at home or at work, while they will not spoil the interior.
According to the principle of their own work, air units can be compared with heat fans, but their power is several times greater. If a household heat fan has a power of 2 kW, then air heaters - more than 10 kW. A characteristic feature is the equipment with closed-type spirals. Due to this, dust does not collect on them and does not burn, emitting a bad smell, like in heat fans.
The equipment does not stop working by heating the pipe coil using electricity. Air is blown to it by a built-in fan. Passing through the pipe coil, it heats up and goes to the middle of the room. The devices have dampers, by adjusting which it is allowed to change the direction of the heat supply to the room. When installing, it is necessary to leave a distance of about 30 cm from the wall surface for air access.
There is air heating equipment equipped with a water tube coil. A circulating heat carrier is fed into the apparatus, which quickly heats up the pipe coil. At the same time, the pipeline has ribbing in the middle. This serves to increase heat transfer. Air is also supplied and discharged by a fan
Important: Air units should not be used if there is a possibility of containing flammable or toxic substances in the atmosphere.
Pros and cons
Equipment that works on the principle of air heating has a number of positive qualities over an ordinary radiator system or electric heaters. Main positive qualities:
- Fast heating. Due to the forced air injection, the heat supply process occurs faster than, for example, in the design of radiators.
- Economy. The operation of the apparatus is several times more affordable than the heat supply by an air conditioner or a boiler. The temperature difference for air heating in the lower and upper parts of the dwelling is more than 10 ° C, depending on the ceiling height. Furnace heating systems involve the supply of air from the ventilation ducts. Even if they are placed in the floor, warm air rises to the ceiling, which will take a long time to heat up a room with large ceilings. And air units make it possible to regulate the direction of warm air, thanks to which heating occurs evenly.
- Minimum installation costs. The branching of pipes for water or channels for furnace heating requires a considerable consumption of materials.
- Ease of installation. The installation of the device takes less time than the implementation of another heating system.
Important: Due to the impressive power of the units, they involve connection to a 380 V network. Of the poor qualities of the devices, it is necessary to highlight the inefficiency of use for small areas and not a beautiful appearance

Water heat exchanger
Air heating units using water heat exchangers heat the air in the building as quickly as possible due to the heat carried by the circulating water. At the same time, the pipeline has ribbing inside, which increases heat transfer. When blowing, this heat exchange only increases. Having read all this, you can mistakenly confuse this unit with conventional fan coil units.
Electrical devices of this kind, both structurally and functionally, are very close to household fan heaters - electricity heats a heat exchanger, to which air is driven by a fan. The dampers direct it further to the desired part of the room.
But the differences between them, of course, are:
- Open-type spirals are practically not used. They can serve for a relatively short time, and the dust will burn if it gets on them.
- These units are designed for heating a large room. These are no longer household heaters, here the power is measured in tens of kilowatts.
Technical characteristics of VR1 and VR2 fan heaters
The Volcano fan heater is presented for sale in two versions, which were mentioned in the subheading. In the first case, the number of rows of the heater is limited to one unit, in the second - to two. The maximum air consumption per hour is 5500 and 5200 m 3, respectively. The range of heating power in the first case varies from 10 to 30, in the second - from 30 to 60 kW.
The increase in air temperature is 18 and 33 ° C, respectively. The maximum coolant temperature in both cases is 130 ° C. Volcano fan heaters are also characterized by a maximum working pressure, for both models this parameter is 1.6 MPa. The maximum range of the air stream is also the same and is 25 m. The volume of water in the heater is 1.7 and 3.1 dm3, respectively. Male threads have a диаметр inch diameter. The Volcano VR1 air heating unit weighs 29 kg without water, while the second of the described models weighs 32 kg. The engine power in both cases is 0.61 kW. The engine speed remains unchanged at 1310 rpm. The second model has a motor protection class within 54 IP.

The principle of operation of the air heating unit
However, such equipment still has some specific features:
- the power that the air heating unit possesses is quite high, much higher compared to a traditional fan heater with a power of 2 kW;
- an air heating device is most often used in industrial rather than residential premises, since the design of the product does not play a big role, its reliability and durability is much more important. Nevertheless, today you can find such models that have a beautiful appearance and can be installed, for example, in an office space;
- the main heat carrier can be not only electrical energy, but also water. It is the heat sources that should be considered in more detail.

Advantages of air heating units
If we talk about how diesel air heaters, as well as the same devices operating with a different heat source, differ from other standard heating devices, we cannot fail to mention the following list of their advantages:
- the rate at which the room is heated
... Due to the blowing off, more heat will be used than in traditional convectors; - ensuring uniform heating
... With the help of built-in dampers, the flow of heated air can be directed in any direction, which cannot be said about convection devices, where warm air can only move upward (more: ""); - high efficiency indicators
, which is explained by the previously mentioned ability to evenly distribute warm air; - simplicity and ease of installation
... The design is based on only two pipes - supply and return, so their installation can be done quickly, and in the case of a large pipeline, this process will significantly slow down and become more complicated.
The main types of air units for heating
An electric heating unit can be classified according to two criteria: the type of heating element and the air flow rate. If average consumption of heated air is required, which should not move throughout the building, then axial fans are used. If we are talking about more powerful systems that are designed to serve entire buildings or several rooms, then they work at the expense of
An air duct is fixed on the free side of the heat exchanger flange; it is necessary for heat distribution within the entire structure or one room. To provide heating of the air inside the equipment, steam, water or electric heat exchangers are installed. The area of use of electric heaters is limited, there are several explanations for this. The first is the lack of electrical power on the line. To obtain 1 kW of heat, 1 kW of electricity is needed, this indicates that a hall of 500 m 2 will require a power equal to 50 kW. There are few networks that are designed to supply such an amount of energy.
The main advantages of Vulkan air heating units
If you need a heating unit, then you can consider one of the above models as an option. The main advantages of these devices are:
- high efficiency of the fan heater;
- low operating costs;
- optimal range of the air stream;
- reduced noise level;
- high thermal power;
- full regulation of technical parameters;
- simple and quick installation and assembly.
With the help of this equipment, you will be able to heat up, and in the future to maintain in automatic mode the desired level of air temperature in the room or building. In this case, the coolant will be heated to a mark of 90 ° C. The Vulcan heating unit does not use air masses from the outside in its operation, as it is designed to recirculate the air that is inside the building.
As an additional feature, we can highlight the fact that the units have the ability to redistribute air masses, this is provided by built-in axial fans and guiding louvers. With the help of the latter, streams can be directed to almost any part of the structure or room.
Description of VOLCANO VR
Poultry and livestock complexes are also equipped with such units. Their main advantages are the speed and efficiency of heating, low noise level during operation, the ability to adjust parameters in accordance with needs. Heating equipment is not capable of violating the aesthetics of the interior; it can be combined with almost any style solution. The use of such units saves money, because they are economical and consume little electricity. Such air heating units, the price of which is 25,200 rubles, can be used as a heat curtain when entering through an opening gate.
