All the swimming pools are cold!

I always found it intriguing that when you're getting into the water for the first time, the water feels much colder than the air... but when you've been in the water for some time and get out, the air feels colder than the water.
And have you noticed that a pool heated to 27 degrees doesn't feel as warm as 27 degrees of air temperature Slow.Patrol said:

Water conducts heat something like 20 times faster than air. At a comfortable air temperature you'll be losing heat to the air at a similar rate that you're generating it, but at the same temperature in water you'll lose heat faster than you're generating it.
Leisure centres have massive roof areas, why are they not covered in solar panels and evacuated tubes to heat the pools and sell the excess energy so that the money can be used to heat in winter?
The whole of the UK could be supplied with all the elec it needs with just 30 sq miles of Solar....that would not be hard to do based on the solar farms we already have plus every govt / local authority owned premises.
The new build developers always promise massive infrastructure when they build but often under deliver - they should be forced to build the new leisure centres before they are allowed to complete the sale of the first new house and they should pay for a wind turbine and solar.
There are 5000 new houses in the town near us, each house has 2 or 3 solar panels on the roof to meet the targets...the whole roof should be solar now and the excess should be for the benefit of the local areas such as schools and leisure centres (also covered in panels)

Yep same with ours. It does vary but the kids can (and do) turn blue.
We've got our money back a couple of times when it was just silly.
There's a huge difference between 27/28 and 30/31 degrees.
There should be no issue with water at 27/28 degrees - that is the industry standard temperature for pool water. I had swimming lessons back in the 80's aged 6-10 in water at 27 degrees.We've got our money back a couple of times when it was just silly.

30/31 would be too warm for a commercial pool. The amount of extra energy required to go from 28 to 31 is huge, not to mention warmer water means more air heating and dehumidification, higher chemical consumption, and on top of that pool equipment such as covers would degrade much faster at that temperature, further adding to the running cost.

Those roofs often weren't designed with solar in mind. Solar PV is about 20% efficient and can be exported easily. Solar thermal is much more efficient but hard to export heat. Other issue is that in summer you'll have way more heat than you need.I do agree that Solar on roofs should be much more common.

I suppose the next thing is they'll close them as they'll say no-one is using them.
Local Councils at their best.Swimming pools cost money to heat, solution, lower the temperature, result people stop going. Council closes pool because of "lack of use", pocket cash sell land for "redevelopment".
In the same way they kill town centres. Build out of town shopping areas, result footfall in town falls. Councils see the drop in revenue from the town centre and increase parking charges and business rates to claw income back. People stop going to town, shops shut.

There's a leisure centre in SW Birmingham where they use the energy created from a crematorium to heat the swimming pool!
All swimming baths should incorporate a body disposal scheme IMO.
It was considered for the Aldershot Lido too, which is next door to the local crem.... but the lido is still unheated. All swimming baths should incorporate a body disposal scheme IMO.

Now it's 27 or 28 and feels freezing, especially so when you've got the surface area to volume ratio of a 2 year old. Hell it's too cold for me if I'm sat in the toddler area just watching them rather than doing laps.
That's the exact same pool just 30 years apart.
And while we're on the rant our local pools with water slides (The Dome and Metrodome) used to be open everyday, my dad would often take us midweek after school. Now it's weekends only and only for 90 mins, we used to spend hours at both.
Guess it's important that we pay a little less tax. Suppose we could close them on weekends too and save even more.
Previously we used to belong to a private club where the pool temperature was 31/32. It was far too hot for me.
They had a boiler breakdown one week and the water got down to 21. I had to plead for them to let me in. Best swim ever and I had the whole pool to myself. I did have to remind myself to breathe during the first length.
I really need to find somewhere I can do cold water swimming, not easy in a land locked county.
I was once told that the higher the water temperature, the more chlorine and chemicals were needed.

I've noticed this. I take our 9yo and to be fair to him he doesn't complain as he just thinks that's what they are like, but it's miles colder than I remember it as a kid.
You must be fairly young then. When I was a kid, it was the sea, or an outdoor swimming pool. Very few indoor pools existed back when I was a kid.40yrs ago I went to my local leisure centre pool every week and it was like a nice tepid bath. Nowadays when I visit the same pool with our son it is noticeably colder.
king freezing even way back then!
