secondary heat options
My great aunt recently asked me for some input on what to replace her two propane heat/air conditioner units with. No, I’m not a professional, but she knows of my interest in this board.
The package units are both 10-12+ years old, and are on their final legs. The outrageously expensive propane (no NG option) is only used for heat, otherwise she’s all-electric.
Located east of Birmingham, AL by 60 miles, the electric rates are not bad, so I plan to advise her to go with heat pumps.
It’s the secondary heat I need your input on. I happen to think that electric strip heat is the most RELIABLE (if not the cheapest for her conditions). In her relatively mild winter climate, I just don’t think of propane heat as a backup is worthwhile. And a propane dual-fuel package wouldn’t amortize in a reasonable amount of time, considering the unknown prices of propane in the future.
Do you concur?
HP with electric back-up is the way to go.
If I was that far south, I wouldn't even put electric heat in.
Rheem does have a dual fuel packaged unit.
Karst means cave. So, I search for caves.
Make sure she has enough electrical service for the strip heaters.
Going to need aux heat for the defrost cycle atleast. Plus you have some hours that the HP might not handle the load by itself.
