IF YOU CHOOSE A HEATPUMP every single stage compression has almost the same performance. Regarding the law of labeling the COP is declared on +7 air temp and 35 degrees water temp. in this diagram you see the diff of COP. When you choose a heatpump of 9.5Kw ad +7/+35 it has by -15/35 6.2Kw to compensate this is a electric BACK UP heater of 3 KW (13amp) needed 6.2+3=9.2KW heat output. electric input is 5Kw COP (1.84). KoFri heatpumps dont have a BACKUP heater, Temp lower then -10 our compressor goes from a 1 stage to a 2e stage compression thats why we dont need a BACKUP HEATER. THATS THE TRUE NOW YOU KNOW.
