Description There are three main types of heat pumps, There are three main types of heat pumps, vapour compression, adsorption and absorption heat pumps. <br /> In the majority of cases compression heat pumps are used. For operation they need mechanical energy. Heat pumps reverse the natural heat flow from a higher to a lower temperature. In heating mode heat pumps transfer heat from the surroundings into buildings. In cooling mode they transfer heat in the opposite direction. <br /> The most frequently used sources of energy for heat pumps are air (Air Source Heat Pump, ASHP) and water (Water Source Heat Pump, WSHP), but also soil and waste can be used. Centralized and decentralized heat pumps are available, whereby the latter are used to heat or cool one room or part of the building only.ool one room or part of the building only.  +
