I'm planning for my second year with our Splash 17X29 15,000 gallon pool. Along with an extensive deck build, I'm considering a method of heating. I live in North Dakota so pool season is a little shorter for us. Even when the day and evening temps are very reasonable, it can still dip down quite a bit at night in the early and late summer. The result for us is a pretty cool pool at around 77 degrees or so. A source of heat I think could extend our swimming season a couple weeks on either end. I looked at gas heaters but they burn a HUGE amount of fuel and at the price of propane...seems prohibitive to me. I do plan on putting some solar panels on my roof like the Fafco Solar Bear Economy Heating System. I have also been looking into heat pump pool heaters. www.poolheatpumps.com It seems to me that this method would be the most efficient. I'm having trouble finding anyone with first hand experience via my forum searches to give me a report. The initial cost is a bit high at around $3K....but If it meant that I could $reasonably$ heat my pool and keep it at 84 deg then it would be well worth it to me. Anyone have any experience with these units?
Also regarding the solar mats.... I live in a 2 story house that is rather tall. Would there be any issue pumping water up the height required to reach my solar panels?
