SEER, COP and HSPF
I am trying to come to grips with SEER, COP and HSPF.
Is this correct:
SEER is BTU cooling / watt hours needed. So divide this number by 3.412 to get the COP. Thus a 16 seer unit would have a COP of 4.7 or so.
HSPF is BTU heat produced / watt hours needed. So take a heat pump with a HSPF of 10, which is supposed to be pretty good and divide that by 3.412 = a COP of 2.9.
Have I done that correctly and, if so, are there heat pumps that do better than a 10 out there?
