This is beyond my brain today!
If you have a room heating load of say 8kW and install a 12kW inverter heat pump system will the COP be higher than a 8kW system installed for the same heating load.
The thinking is this, the evaporator and condenser coils are oversized and the compressor will never need to run at full speed so power consumption will be less for the given capacity than the correctly sized system.
Am I missing something here?
Thanks
