    COP can certainly be 1.82. COP does not take defrost into account, but you will normally create more watts of heat than the watt input. Problem is you can not generate enough heat, so supplemental...

    Just a comment of clarification. As it gets colder, below 40 deg, the heat pump does NOT get that inefficient. This is somewhat of a myth. Most heat pumps will generate heat quite efficiently into...

    Water quality is the bottom line on open loop systems. Closed loops do not have these issues, but as said have a somewhat lower efficiency due to loop temperature variations.
