Electric heat pumps are extremely efficient because they transfer already existing heat from the environment into a building.
Modern electric heat pumps work very quietly and require virtually no maintenance. They mainly use the energy stored in the ground, groundwater, or air for space heating, domestic hot water, ventilating, and cooling. By reducing energy consumption compared to old and inefficient systems, heat pumps already cut CO2 emissions. Even further emission cuts can be achieved by using renewable electricity, e.g. from wind or photovoltaic energy sources.
Various electric heat pump technologies adapt to many needs: to heat or cool rooms and to produce domestic hot water.
Moreover, they are suitable for different types of buildings: residential or commercial; with access to a water source (water- water heat pump) or to a large garden (ground source heat pump) and bring great comfort. They reach their highest efficiency level in combination with: well-insulated buildings; distribution systems working at low temperature,i.e. underfloor heating and large radiators; higher temperature of the heat source (soil, groundwater or air).
