Overview of benefits

Can be mounted on the wall or cylinder (SPU-2) without the need for expensive accessories

Electronically controlled, only the temperature needs to be selected

Highly efficient DHW circulation pump can be integrated as an accessory

Fully pre-assembled with attractively designed thermal insulation

Scale prevention through admixture in the primary circuit

Infinitely variable output adjustment thanks to a variable speed pump

Automatic readjustment for outstanding DHW convenience (FWS-2-80: electronic, FWS-2-60: thermostatic)

FWS-2-80 including taps on the DHW side of the heat exchanger

FWS-2-80 including thermal disinfection function 

Preconfigured cascade sets of up to 4 units (FWS-2-80)

Cascade sets comprising freshwater modules, cascade controller, cascade valves, DN50 piping and hygiene kit

Well-insulated cascade piping
