Pool heating

Postby olive » Wed Jan 19, 2022 9:30 pm

This is a subject that comes up from time to time on the forum and indeed in our household.

The idea is to extend the season. We are going to invest in a pool cover to retain heat. For that I reckon 200 euros for the winding drum and maybe 8 euros a sq m for the’ bubble wrap.’

Now to heating. 5x10 m and 80 or more cu m of water. A few years back we tried a DIY solution of 50 m of black pipe teed into the circulation. It sort of worked but was a nuisance.

Things have moved on hopefully over the recent years. We only have a 5.5 kw supply and a 1 hp pool pump will use a chunk of that but electric heating is a possibility. Solar panels on a “pergola “ that could act as a car port might be an idea.

Anyone have pool heating or seen a place that does them? I don’t mind travelling .

What are the possibilities?

Probably too expensive an option, but we decided on a telescopic polycarbonate cover which was fantastic - swimming at night without dodging insects & being able to dry off out of any wind was great :-)

Using a heat pump will work well but you will need more than a 5.5 Kw supply.

Solar panels or an improvement on your irrigation pipe system will be a lot cheaper.

Hmm. Upgrading the electric supply no doubt would fall on the householders shoulders. At least 500 metres of overhead twisted light cable and no doubt change wooden poles to shiny pylons. So apart from the sheer cost would go against the grain. A neighbour wanted their single phase bell wire supply upgrading to 5.5 kw and they were quoted 4000 for three poles .

So that leaves running an under powered heat pump in overnight when usage of other electrical items is lower. Not very satisfactory. I believe that a 5.5 kw is the right size for a 5 by 10 pool . Or the solar panels over a car port which would provide shade. Just need to find someone doing that.

I have seen the polycarbonate sliding cover. I assumed that they don’t do much actual heating just stop heat escaping so much. We would rule one out on aesthetics ( having to look at it fro twelve months) reduced area of terrace. One joy is being in the pool while swallows or later bats are drinking on the wing. A cover would limit that. Insects have never been a problem for us. Inland , altitude, lack of nearby surface water?

I understand what you are saying, but the beauty of the telescopic cover is that you can have as many or as few sections open as you like, so you can still look up at the stars ! You are right in that it doesn't actually heat the pool, but it sure keeps it in !!

50m, wow. Our solar system has approx 750 metres of pipe...

We didn’t have a suitable space for anymore pipe.
