When our heat pump is on supplementary heat how many BTUs are produced for each KWH of electricity?

Ran into a house last week that had a gas stove and an electric furnace in the attic, built 2010. Didn’t quite understand what the builder had in mind on that one…

How do I know if I am using supplemental heat with my heat pump.We have a 14 seer heat pump system with 80,000 btu propane F/A furnace. We have had minus 0 Degree Fahrenheit temperatures. Is is more efficient to run just the propane furnace and not pay extra hydro to run the heat pump on these cold, cold days.?

Hi Allison, 
 
Have you done any study of the efficiency of micro-CHP? It likewise attempts to boost efficiency by effectively transferring source energy to site energy (of course, that’s my paraphrasing – hope I’m not driving you nuts with it! 🙂 But the gear itself is very expensive. Was just wondering. Thanks!

Very true, Steve. That’s why the next time I get a chance to build a house, I’m going with ductless mini-split heat pumps. I won’t have any duct leakage if I don’t have any ducts!
