Is a DC inverter heat pump worth it?
This knowledge and experience undoubtedly confirm to us that variable frequency heat pumps offer significant advantages, in terms of Higher annual energy performance. Lower likelihood of having problems with grid connection. Space requirements.
Most heat pumps use single- or two-stage compressors. That is, it is closed or open. Our R32 DC inverter heat pumps feature the best compressor in the industry.
This DC motor runs at the exact speed needed for optimal efficiency. This way, the average efficiency of a DC heat pump is 30% higher than a standard unit. This is very important because the compressor consumes most of the energy needed by the heat pump. By reducing the energy consumption of the compressor, the COP (Performance Cooperative Efficiency) is significantly improved. The brushless DC fan motor and PFC regulate the operating power and eliminate the need for starting capacitors. Since our motors do not need to be constantly started and stopped like conventional motors, they reduce both energy consumption and compressor wear.
● Full inverter technology
● R32 refrigerant
● SWEP plate heat exchanger
● ERP A+++
● For heating, cooling and DHW
● Smart WiFi control
● Pre-set selection of the appropriate climate curve
● Low running noise
