SET 2.0 wall-mounted for DHW production

Fresh water station for DHW

The Fiorini SET 2.0 is the complete “plug and play” product to transfer heat from a buffer tank with technical water to water in the domestic network, guaranteeing the instantaneous production of domestic hot water.

The set is made up of a control unit (S or L, selected by the user based on the requested functionality), circulator with electronic control unit, heat exchanger in stainless steel AISI 316, metal body and thermoformed panels for mounting to the wall.

Thanks to the elevated efficiency of the heat exchanger, the SET 2.0 fresh water station for DHW is ideal in heat pump systems or systems with solar panels, which use low temperature (50-55°C) buffer tanks.
