DHW module FW-D 40

Central hot water preparation with heat exchanger based on the flow principle

Our DHW unit FW-D 40 heats the domestic  water centrally and supplies it via hot water pipeline to the domestic water tapping points.
A thermal storage tank is necessary in order to provide the required heating water quantity for heating the domestic water! The DHW water is only heated when “Just in Time” is requested. There is no storage of hot water!
