Pool heating methods and costs

You can have the residents "pee" in it! LOL!!! Sorry couldn't resist. Maybe need to ask around to different pool contractors. I would be worried about the evaporation and the costs of constantly replacing the loss water. The sun doesn't heat the pool up enough on it's own? Our pool stays cool in the early summer but by late july it's like a sauna. I personally like the water cool since it feels good after sunbathing.
You may even call up a local hotel like Holiday Inn, who have heated pools and how they do it. Atleast find out who the call to handle the pool so you may call them as a possible contractor.

Hi Don:

Depending on what state you are in, how many sunny days you average, the amount of shade your equipment house and/or pool house get, going solar may be a great deal - saving money over time, as well as saving the environment. You may need a back-up system as well. Part of it will depend on what months you use the pool as well. Use of a pool cover when not in use will save you money as well, since it stops or slows evaporation.

Beyond that, it's looking at gas/oil/electric heat, guessing what prices are going to do, etc. - a good pool contractor could help on that.

Unless you don't mind your pool going green & icky over the non-use months, you'll need to do some heating through the rest of the year, as well as doing some regular chemical treatment.
