Domestic hot water heat pumps for all situations

Whether modernising or building from scratch, detached house or apartment block, as part of a WOLF complete solution or as an individual appliance to supplement the existing heating system (biomass, oil, gas) – WOLF domestic hot water heat pumps are designed for an impressively wide range of applications.

2

wolf

Easy installation

All domestic hot water heat pumps are delivered fully wired (230 V). Practical, screw-in carry handles make transport easy.

3

wolf

Simple operation & quick configuration

Intuitive operation with rotary selector. All important functions can be set in a single main menu.

4

wolf

Flexible operating modes possible

Circulating, extract or outdoor air operation can be implemented, depending on the model.

5

wolf

Reliable & hygienic DHW heating

With the practical, individually configurable pasteurisation function, the FHS remains perfectly hygienic all year round.
A 2 kW immersion heater is standard on every appliance to ensure a sufficient heating reserve.

Optimise your energy consumption

Effectively use excess electricity for DHW heating. A two-wire cable is all it takes to connect to the inverter with PV output. This increases independence from the grid.
