Note: Heat pump. We recommend this type of tank only with certain reservations when used in conjunction with a heat pump! This is because the “low” flow temperature of the heat pump (usually 50–55°C) can lead to limitations in hot water comfort. We recommend our EHSWP tank, which was developed specifically for heat pumps! About EHSWP
