Air heating system for a private house

With technological progress, mankind began to use an increasing number of heating equipment, where not only firewood, but also gas, electricity, coal, etc. are used as fuel. Thanks to this, it became possible to heat large rooms with different purposes. However, despite the wide variety of systems, the relevance of air heating is not lost, this system is more than 2,000 years old.

The principle of operation of air heating

Throughout the entire existence of the air method of heating premises, two effective approaches have been invented:

• Heat transfer, which is involved in the heaters. The principle of operation is similar to the operation of water heating, only hot air is used as a heat carrier. The air ducts heated by it will begin to generate heat to heat the rooms.
• Direct heating is used in systems with heat generators. Outside air heats up in the combustion chambers and rushes into the premises through the air ducts. This method allows you to achieve the maximum indicators of the coefficient of performance (COP).

The latter method is the most widespread today due to its versatility of use. This heating system can be combined with air conditioning and ventilation systems. In addition, with a reasonable implementation of the project, it will be possible to regulate the local temperature regime by using local air heaters in each room. According to this principle, heating systems are divided into local and central ones.

Advantages and disadvantages

Before giving preference to a particular heating system, you need to carefully familiarize yourself with its features, advantages and disadvantages.

The main advantages of the air system include:

• Due to the fact that air is the most controlled heat carrier, it is possible to regulate the temperature regime in the premises with high accuracy.
• The air conditioning system is universal in its use, since in winter it works to heat the room, and in summer to cool it. Also, this approach allows you to significantly save space in the room, since one installation is enough.
• There is no need to install air heating near the windows.
• Lack of classic heating devices (batteries, radiators). The space looks more aesthetically pleasing, it becomes possible to implement a large number of different design solutions.

Despite the large number of advantageous features, one should not forget about the disadvantages. Unfortunately, there are many of them.

• If the system requires continuous operation of the energy resource in the form of gas, monthly utility bills will be high.
• Bad momentum. Air heating system, in comparison with alternative heating methods, is the most non-inertial. This indicates that when the system is turned on, a person feels the heat he emits, but if you turn it off, the room will quickly begin to cool down. This is one of the main disadvantages of the system.
• A large amount of air is required to heat a room, therefore, care must be taken to install wide air ducts with a large cross section. Mostly they are hidden in the ceiling space, which often interferes with designing an interesting design.

When the room is heated with air, it is not possible to maintain the comfortable parameters of the microclimate.All radiators warm up the air, and it rises up, and the air conditioning systems are installed at a height. Thus, the upper part of the rooms is warm, while the floors and lower part are cold.

Calculation of the air heating system

Making all the calculations on your own is not an easy task. In order to take into account all the nuances and not have to redo the project in the future, it is better to entrust this work to professionals. When calculating the power of air heating, first of all, it is required to determine:

• the size of the weakening of the pressure along the entire duct;
• heat loss in every room;
• the dimensions of the duct pipes;
• design power, determined by the total heat loss and the type of heater used;
• the volume of air required for high-quality heating of the living space.

If there are difficulties in choosing equipment, you will also need to consult a specialist. He will talk about the features, advantages and disadvantages of each modification and determine the appropriateness of the choice in a particular case.

When implementing a project, it is important to take into account a large number of building codes and regulations, non-observance of which can disable equipment and create problems with state regulatory authorities.

DIY air heating of a private house

When implementing a project, it is extremely important to take into account the optimal type of fuel that the system will use to heat the air. Increasingly, the world's leading manufacturers produce hybrids - systems that run on different types of fuel. The most common example is the switch from natural gas to liquefied fuel. For implementation, it is required to change the nozzle that feeds the raw material and the burner.

If the choice fell on equipment operating on liquid fuel, you should definitely take care of purchasing a tank for storing it. An air heating system combined with ventilation must be equipped with special filters and air vents. The assortment is great, they can be square, rectangular, round and combined.

The implementation of an air heating system is an excellent solution for apartments and country houses with a small area. However, it will be possible to achieve high efficiency only with proper design, selection of equipment of optimal power, its correct installation and operation.
