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

Description

The EH hygienic stratified combination storage tank is suitable for heating water storage and domestic hot water heating, wood-fired heating systems, combined heat and power (CHP) units, and conventional heat generators.

Because the water volume is limited to 30–50 liters and the “flow-through principle” is used, no precautions against Legionella risk are required in accordance with DVGW Worksheet W551.
Equipped with a sensor terminal strip for variable positioning of the sensors.
