Thread: Heating up above ground pool

    Heating up above ground pool

    As I've mentioned our AG is FREEZING (68-69F). We are contemplating emptying out a bit of the pool (it's actually overflowing from a big rain storm we had yesterday) and adding hot water from the house (our basement bulkhead is pretty close and can easily hook up a hose by the washing machine). I'm just wondering if anyone has done anything like this and if it helped at all. If we did JUST hot water for awhile I just wonder if it would bring it up a few degrees. Suggestions? Input?

    Do you have a solar cover? We keep ours on night and day when not in use and does a great job of heating/maintaining heat. If you want quick fix the hose may work but I would think it would take quite a bit of hot water to raise it.

    We don't have a solar cover yet--we plan to get one for next season since ours is just about over . I'm thinking it may take too much hot water and not really be worth it. Oh well!

    Think how 40 gallons of 120* water will compare to 4000 gallons of 68* water....

    Any sort of cover will help to some extent. Even a blue poly tarp.

    Most of your heat loss is due to evaporation from the surface, so if you can control that, your pool will slowly warm to a decent swim temp.

    My own experience with this: Without a cover, water temp closely follows air temp; with cover temp doesn't drop much, with as high as 20* difference between air and water temps.

    We do have a regular cover we use--just not solar. My husband is draining some water now and we're going to add some hot water to see what happens
