A heat pump is a device that allows you to use the thermal energy of air, soil or groundwater for heating and / or hot water supply. The heat pump collects heat from the street or from the ground and directs it into the house. According to the source of thermal energy, heat pumps are subdivided into the types "soil-water", "water-water", "air-water", "air-air".
The main criterion that determines the efficiency of a heat pump is its transformation ratio (COP), which shows the ratio of the generated thermal energy to the consumed electrical energy. The higher the COP, the more efficient the heat pump - less electricity is used with higher productivity.
