Efficiency class: Full A Inverter-plus is the heat pump with the highest efficiency class - class A. The COP is 8.2 ~ 5 (from low speed to high speed, air 15°C / water 26°C / humidity 70%), and it is 50% higher than ordinary on-off heat pumps, and 25% higher compared to the normal inverter heat pumps.
Full inverter technology. Inverter-plus has been designed with full-inverter technology, which regulates the compressor speed hertz by hertz, intelligently and continuously and with maximum efficiency. If necessary, the inverter plus HP allows to decrease the heating capacity from 100% to 33% automatically.
