All the swimming pools are cold!

Don't get the obsession with baby swimming sessions, if they aren't in control of their bowels they shouldn't be in a public pool.

I guess you don't open water swim then...

When we were kids it was always 31 and it was lovely and warm.

Now it's 27 or 28 and feels freezing

That's the exact same pool just 30 years apart.

Got to say that sounds absolute nonsense - you can tell a three degree difference in water temperature 30 years apart?

I was once told that the higher the water temperature, the more chlorine and chemicals were needed.

The pool water will be maintained at the same chlorine level regardless of temperature - but the warmer the water the more chlorine it will consume, so it will take more chlorine to maintain that level.

As Sodium Hypochlorite is an Alkali with a high pH, more chlorine going in means more acid being pumped in to maintain the pH balance, and just generally greater cost.

I can't remember where I saw it, but Exmouth leisure centre's pool is heated using the excess heat from their server room. Apparently there is some process where the server room is kept cool while the swimming pool is kept warm and everyone's a winner. Perhaps they could look into that?

My day job. Even a small council will be putting out 50-60kW of heat all year round, that will heat a swimming pool via a heat exchanger, so an easy win.
