HEAT PUMPS
Heat pump is a heating equipment that uses solar energy accumulated in environment — soil, water, longhole and air. It can be said that the heat pump operates just like a fridge, just according to opposite principle: from outside to inside.
There are also models of heat pumps that work in both directions and can ensure both heating in winter and cooling in summer.
Energy generated by a heat pump can be used all year for heating and heating up the water. The most popular types of heat pumps are of earth, geothermal well and open water basins. The heat pump uses electrical power for operating compressors and circulation pumps. Depending on the heat source used and type of heating system, the heat pump can produce 3-5 times more energy than it consumes.
