    Product details

    Choose a powerful partner for your hot water

    Robust and especially powerful – these are the defining features of this air source heat pump. The compact appliance with stove-enamelled metal casing is specially designed for your qualified contractor to install in your garden. From there, it will supply several draw-off points in your home with pleasant hot water, and ensure reliable operation and a long service life as well.

    Link up to self-generated electricity

    If you use your heat pump in recirculation air mode, it can also be installed indoors. Wherever you site the appliance, it can do more: do you generate your own solar power? Then make use of that for your DHW heating. The heat pump can be easily linked up to a photovoltaic system.
