When we are dealing with systems that distribute air from a fireplace, there are two ways in which they can function.

Natural circulation with convection is at the forefront, but it is also possible to place turbines above the fireplace. The natural system, although often used, is not free from defects. Its operation is not dependent on electricity, but it is only possible for short distances. As a result, the fireplace must not heat more than three or four rooms. If we decide to install an electric turbine in the system, the hot air flow will be forced. It is often placed under the fireplace insert, but the one placed over the fireplace is much more effective. The turbines above the fireplace have a throughput of up to 600 m3/h. They also have the advantage that they can handle the distribution of air even when it reaches eight or even ten rooms.

Nothing prevents the fireplace from being used as a heat source in the water supply for both radiator and underfloor heating. Of course, in this case, a fireplace with a water jacket is used. Unlike open fireplaces, in this case we have to take into account the fact that the flue gases from the combustion slope will not be sufficient to heat the air. However, they can be used to heat water. In fireplaces of this type, only a small part of the heat is transferred on the principle of radiation (maximum 20 percent). The rest is the heat transferred to the water, which removes the heat from the walls of the jacket and transfers it to the heating system. In such a case, the thermal power can be from a dozen to 40 kW. Of course, talking about power requires a certain reservation. It is variable, because it is affected not only by the amount of fuel, but also by the phase of its combustion.

How to create a fireplace corner

If you are thinking about the arrangement of the living room, a particularly good solution may be to use a fireplace insert, although an interesting solution is also a fireplace cassette. Both solutions work in a similar way, although the cassette can be installed in a fireplace that already exists. The term "fireplace inserts" refers to closed hearths. They are made of steel and cast iron, i.e. materials that are known to absorb heat and are resistant to high temperatures. They are equipped with a flue gas outlet, while the glass door is very fashionable. Of course, only a small part of the heat of the inserts is dissipated through the glass. The heat transfer via a heating sensor, such as air and water, which supplies the heating system, is much more important.

Fireplaces with inserts are used in a wide range of applications. They are most often used in homes as an additional source of heat and are used to heat rooms during so-called transitional periods. Their advantage is that up to 80 percent of the energy generated in the house is left in the house, and this requires up to 6 times less wood than open fireplaces. It may be also pleasing that the choice of cartridges is very large, although they differ in size, power and shape.
