Heat Pumps - How they work


A Heat Pump transforms heat from a low temperature level into heat at a high temperature level at which it can be used for heating purposes. Even in wintertime with temperatures far below 0°C a Heat Pump can take energy from the environment.This is performed by an endless “cooling” cycle. The cooling liquid evaporates at a very low temperature and takes a substantial amount of energy from the ambient air, when changing from a liquid to a gas phase.
