4.8.1 Domestic hot water tanks

A domestic hot water tank is used for the production and intermediate storage of domestic hot
water (DHW). By integrating a solar system, solar heat can also be stored in this intermediate
storage and used in addition to the heat from the Aquarea heat pump. An electric booster heater
(tank heater) additionally ensures maximum comfort, even at very low outside temperatures, and
can also be used for sterilisation.
Panasonic offers various DHW tank models in different sizes for easy domestic hot water
production for different requirements.
