The S203 keeps the temperature of domestic hot water at the des-
ignated value. Because of the danger of bacteria, it is recommend-
ed that the domestic hot water temperature is not permanently set
below +55 °C.
The upper part of the accumulator is heated by a compressor and,
if necessary also by an electric heater, so that hot domestic water
is obtained.
