Freshwater moduleĀ 

FWS-2

The WOLF FWS-2 provides you with hot water for the bathroom and kitchen using the principle of instantaneous water heating, which is absolutely hygienic and particularly energy efficient.

Instant DHW heating

Freshwater modules extract heat from a buffer cylinder and transfer this heat to fresh water flowing through the system. The WOLF FWS-2 freshwater module is available with several output ratings.

The FWS-2 versions with tap outputs of 15 and 40 litres per minute are freshwater modules suitable for detached houses. The larger models have tap outputs of 100 and 130 litres per minute and enable freshwater modules to also be used in apartment buildings. Cascades of up to four FWS-2 modules are no problem at all and can be used in situations with higher output requirements. A further model, the FWS-2-60, is a compatible with WOLF stratification cylinders.

Benefits of freshwater modules

Efficient

Hot water precisely as and when needed

Generate your hot water instantaneously only when needed. No storage is required, making this a particularly efficient form of DHW heating.

No need to heat the cylinder

WOLF freshwater modules make it unnecessary to regularly heat the storage cylinder to kill off Legionella bacteria. This also cuts the cost of heating.
The WOLF FWS-2 is one of the most efficient freshwater modules on the market. It transfers heat to DHW with outstanding efficiency. Read more

Perfect coordination

Supports stratification in the cylinder

Freshwater modules support stratification in cylinders as they extract hot water from the top of a cylinder and feed cooled heating water back in at the bottom.

Ideal for solar thermal technology and photovoltaics

Solar thermal systems achieve particularly high yields in combination with the FWS-2 thanks to stratification of the cylinder. Freshwater modules are also ideal for increasing the amount of PV energy used on site. Read more

FWS-2 in apartment buildings

In apartment buildings, central DHW heating using the FWS-2 freshwater module is a viable alternative to the decentralised CAT floor station.
