The tap water is supplied via an integrated boiler. It is heated indirectly by a coil in the boiler. The primary water
circulates in the coil thanks to a pump and is kept at a temperature of 85°C by the heating sensor. When the
temperature detected by the boiler sensor is 1°C lower than the set temperature, the heating pump stops and
the tap-water pump starts up immediately. In this way, heating is turned off and the boiler exchanges with the
closed circuit water that in its turn yields the heat to the tap water contained in the boiler.
