Special highlight: Operated with the natural refrigerant propane (R290), the Basic Line Air Bloc belongs to the most modern generation of heat pumps and is particularly environmentally friendly and sustainable. Thanks to particularly high flow temperatures of up to 70 °C, the Basic Line Air Bloc is not only suitable for use in new buildings. The series is also an optimal system solution for renovation projects.
