Alright team- I think i finalized that a heat pump in the way to go in Newton, KS for heat. I have a 18X36 in ground salt pool with dark CoverStar auto cover. By the looks a 125BTU electrical heat pump would play nice. Found one at Inyo pools for a good price. Anyone have feedback on the Pentair Heat pump model or recommend a buying site? Best prices so far has been Inyo pools with free shipping....Thoughts/Feedback and GO!!
