Pump stations and heat exchange modules
Heat exchange module FriWa
FriWa is a DHW heat exchange module for comfortable and hygienic water heating which works on the principle of an instantaneous water heater. Warm water is immediately available. Hot water storage is not necessary, as the heat required is taken directly from the buffer storage via the plate heat exchanger. It is completely pre-assembled and the controller is integrated. FriWa is available with or without a circulation pump.
