Heating

Heat pumps operate on the same principles as a refrigerator - except that the process is reversed. A heat pump extracts some of the thermal energy stored in the ground or in the groundwater (this stored energy is constantly replenished) and converts it into space heating.

The system works all year round. Below a certain depth the ambient temperature and the temperature of the groundwater are no longer affected by seasonal changes.

Passive Cooling

During the summer, your Weider heat pump can be combined with an additional cooling set (optional accessory) to reduce the room temperature by around 2-4 °C. The water in your underfloor heating system absorbs the thermal energy, and this is then dissipated into the ground via the heat pump. Only the economical recirculation pumps need to run for this to work, so the compressor can remain switched off and does not consume any electricity.
