hot water

Domestic hot water is delivered by the Hygienik Tank which acts as a thermal store for the heat pump and delivers domestic hot water.  The tank has an external heat exchanger.  Fresh cold water passes through this, extracting heat from the cold water in the tank.  The result is FRESH domestic hot water.  As this water has never been stored before, this method eliminates build-up of the legionella bacterium.
