    Product details

    Experience a strong performance on any terrain

    One of the most versatile models of all our air source heat pumps, it has plenty to offer – almost regardless of which building you need it to supply efficiently with heat. Even at outside temperatures of -20 °C, this heat pump achieves high flow temperatures and is therefore also ideally suited to installation in a modernised older building. 

    Highly flexible and universally applicable

    If you need to supply a larger building or smaller commercial units, you have the option to connect several appliances and thereby increase the output.
