STIEBEL ELTRON offers various options that allow you to cool living spaces cost effectively in summer with a heat pump. A distinction is made between two processes:
Passive cooling:
With passive cooling, the low temperature of the groundwater or ground is transferred to the heating system via a heat exchanger. The heat pump compressor is not started, i.e. the heat pump remains "passive".
Active cooling:
With active cooling, the cooling capacity of the heat pump is transferred to the heating system. The heat pump compressor is started, i.e. the heat pump becomes "active".
