Demo:Heat Pump

Description There are two main types of heat pumps, vapour compression and absorption heat pumps. In the majority of cases, compression heat pumps, which rely on mechanical energy, are used. Heat pumps reverse the natural heat flow from a higher to a lower temperature. When used for heating, heat pumps transfer heat from the surroundings into buildings. When used for cooling, they transfer heat in the opposite direction. 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.
  • Low CO2-emissions
  • Allows for heating and for cooling
  • Lower operating costs compared to conventional gas condensing boilers
  • Subsidies
  • High investment cost (technology is still very expensive)
  • Limited application of ground water heat pumps
  • Restrictions regarding the use of soil water pumps
  • Decentralized heat pumps: acoustic emission
