Reply to comment by DifferenceMore5431 in Any R32 Heat Pump Owners? by metalandmeeples

Yeah, I have all of the submittal sheets and whatnot but if there's someone here who has used both at the same residence they might have an idea of the kWh impact each one had on their monthly usage.

...but that's exactly what the Energy Star tests are for, so you can compare the actual difference. How could anyone get data like that in their house?

Energy Star reports simply list SEER/EER and HSPF. Heat pumps perform differently depending on the outdoor temperature. When I was sizing heat pumps for my Portland house I used degree-days data along with the Energy Star rating of my existing boiler and the setting of my thermostat to determine how many BTUs I used. Any response I get here might be anecdotal, but the response could still be cross-referenced against degree-days data.
