We have an 18 x 36 lagoon/kidney shaped sports pool (shallow on two sides, 6' deep in center) approx 19000 gallons. When we first moved to Kansas the summers were crazy hot, so when we installed the pool 3+ years ago we did not think we would need a heater so we ran no gas lines. As luck would have it , since we have had the pool, the summers have been very inconsistent and it feels like we are not getting full use of the pool because we may have one good month where it is hot enough to get the pool to a comfortable temperature. I would love a recommendation for a good heat pump.
I also wondered if anyone was familiar with a couple of different things we found. The first is Coates heater http://www.coatesheater.com/ - a pool guy recommended the cph series 240v single phase kw 30. We have also looked at the Little Giant http://www.little-giant.com/pool_heating.html. Finally I have read some positive things on the Heat Siphon http://www.heatsiphon.com/. Does anyone have any thoughts on these options? I probably like the water temp to be about 85ish and as probably everyone would want - I do want to come up with the most efficient way to heat the pool.
Another question I have is on solar pool covers. With that lagoon shaped pool and the winds in Kansas - our one try at a solar cover was pretty comical. Does anyone have any recommendations for a good cover and the best way to keep it from blowing, yet easy enough for a petite woman to remove?
I appreciate any help you can give me.
