Definition: Heat Pump
A heat pump is a machine, device or installation that transfers heat from natural surroundings to buildings or industrial applications, or reversibly from buildings to natural surroundings.
"Heat pump" means a machine, a device or installation that transfers heat from natural surroundings such as air, water or ground to buildings or industrial applications by reversing the natural flow of heat such that it flows from a lower to a higher temperature. (For reversible heat pumps, it may also move heat from the building to the natural surroundings.);
