To ballpark annual heating costs with a conventional heat pump, assume an overall efficiency of about 230 percent before duct losses. (To calculate the heating efficiency of a given heat pump, divide the HSPF by 3.413.) That would give you an estimated cost per year of $764 for our hypothetical Portland house.Installation cost is often a deciding factor, all else being equal.il with 80% AFUE burner: $ 1,875. These numbers are probably pretty close for a house with all of its ducting in a basement or internal walls. If your ducts run through an unconditioned attic or crawlspace, you should factor in at least a 10 percent loss in efficiency for the gas and oil furnaces.
