Heat pumps utilise environmental heat (thermal energy) from the air, ground or water and raise its temperature to the required level using electrical energy (electricity). Heat exchangers are then used to heat water for heating or showers. This process enables heat pumps to deliver many times the amount of electricity used as heating energy.
The major advantage of heat pumps is their high energy efficiency, as they obtain most of the energy they need from renewable sources and only require a small amount of electricity for operation. Heat pumps are used in both new and existing buildings. In new buildings, a heat pump is particularly suitable in combination with underfloor heating or other low-temperature heating systems. Modern appliances can not only heat, but also cool in summer, thus contributing to climate adaptation.
