How does it work?
A heat pump is a heating device that transforms thermal energy from a lower temperature level into a higher one. In other words, the heat pump draws heat from a medium with a low temperature and transfers it to a medium that has a higher temperature.
The low temperature medium, from which the heat is taken, is called the lower heat source. By the lower source of heat we usually mean heat stored in the ground. It is also possible to use the heat accumulated in groundwater, as well as waste heat (e.g. process heat, ventilation heat).
The medium with a high temperature, to which the heat is transferred, is called the upper source of heat. It means central heating or domestic hot water installations which we want to supply with thermal energy.
Approximately three quarters of the energy supply for the upper heat
source comes from the lower heat source (the inside of the
The remaining quarter of the energy is the energy needed to drive the compressor - the heart of a heat pump, which drives green energy from the lower to the upper heat source. Compressors used
in VATRA heat pumps are electrical devices, so all that is needed in order to use a VATRA heat pump in a building is a mains electrical connection.
