    heat pump questions

    I recently installed a 12.1 kw pv solar system for my house. For the last week in sunny conditions it is producing about 10 kwh extra per day. Since I get almost nothing for the extra production (I get paid $.04 per extra kwh at the end of the year) I was thinking maybe a heat pump to add a month or so at each end of the season. Right now the pool is up to at least 80 from mid April to mid October. I know they work better with warmer air temps but if the average in march and November is 60 deg would it be able to raise the temp and keep it in the 80's?

    Probably not. With a solar cover, and full sunlight all day every day it might come close, but with cloudy days here and there it almost certainly wouldn't be able to keep up.

    Here is a heat pump calculator from Raypak that is pretty darn comprehensive. It should be able to give you the answer you're looking for: http://roxwebdev01.pixelgate.net/gas...ak.php?appid=1

    Raypak is hard to beat for anything heating.

    I think a properly sized HP would for sure...mine can do similar numbers in those temps for sure. Of course I have a solar cover that helps keep the heat in at night....the calculator advice was solid though.

    Thanks for the replies, I'll look at the Raypak info and see what they think.
