Heat pump water heater for radiant question

Fluke216 Member Posts: 33
I have two small zones that im going to feed using a standard 50 gal water heater. Question is is a heap pump water heater good for this application or not. I have a wood stove in the basement that would make the area pretty warm that the heat pump water heater would be in, Let me know what you think thanks

    Nope - you’d be cooling indoor air just to heat the water to warm the indoor air. A resistance heater is good enough.

    I tried it in my shop, it discharges 43F air while generating 120F water. Perhaps if you ducted it to outside air? Not a very high output capacity either.
