So we purchased our home this past August, and are opening the pool this year (it wasn't opened last year by the prior owners.) Although it had become a frog pond, thankfully everything works and there are no leaks, so we've been shocking and running the pool to get it back in shape. There is currently a propane heater (Jandy lite2) installed, however the plumbing has been cut, so we're not sure if the prior owner did this because the heater is broken, or just because they wanted to simplify the system for the sake of maintenance (they had been renting the place out for several years before we purchased.) At any rate, the neighbors have been able to fill us in on a lot of details, and the last they knew, when the owners lived there they kept the pool at like 90 degrees all season (cost them something like $900 a month to do so) so we know that it was definitely working up to a few years ago. The neighbors have a heat pump and they swear by it, so we've been looking at this as an option, as we plan to use the pool regularly throughout the swimming season here in New England (as opposed to heating it up periodically for guests or a party.) We're trying to determine what the minimum BTU electric heat pump is that we can get away with, as the darn things are expensive and we're already staring down the barrel of a huge bill to put down a cement pool deck (currently pavers in awful shape.)
All my calculations online would seem to indicate a recommendation of anywhere from 120k-150k BTU, which is a hefty price for a pump. Whereas reading the experiences of others would seem to indicate that we can get away with quite a bit less (one heat pump we were looking at on Craigslist comes in and 90k BTU, and the owner says they've had no problem heating an inground pool larger than ours.) We will be utilizing a solar cover to help retain the heat, and the specs on my pool are in my sig.
Can anyone provide me with some recommendations? Thanks for the help, and as a new pool owner I look forward to reading these forums regularly!
