HEAT PUMP
The heat contained in the surrounding air, land, ground (so-called geothermal heat) or heat contained in the underground or surface water, because their low temperature isn't usually used. This is natural, so-called - low-potential heat, which is renewable, which means - environmental energy source may be using the heat pump is converted into heat at a sufficiently high temperature, allowing its use for heating, hot water and heating water for swimming pools.
RECOVERY SYSTEM OF EXHAUST AIR

The heat contained in the surrounding air, land, soil (so-called geothermal heat) or heat contained in the underground or surface water, because of its low temperature in the usual way is not used. This is natural, so-called - low-potential heat, which is renewable, which means - environmental energy source with the help of heat pump may be converted into the heat with sufficiently high temperature, allowing its use for heating, hot water and heating water for swimming pools.
