    Product details

    Efficient heating with a top performer

    When outside temperatures are far below zero, you’d rather be indoors in a well heated room. Providing you with a warm and cosy interior is no problem for this outdoor air source heat pump. It continues to operate at maximum efficiency even when the mercury drops below freezing. Furthermore, thanks to high flow temperatures, you can even use the appliance to heat traditional radiators.
