11m x 4m outdoor swimming pool in 3 weeks (with paving)

[JulianPH]

And we're back!!!

After much scientific work it was confirmed that the pool was filthy!

[JulianPH]

Plant is almost all in (boiler tomorrow):

[JulianPH]

I'll post some paving pics in the morning.

We have all had a pizza and a few beers. More to follow tomorrow!

Cheers.

[JulianPH]

Thanks everyone, your comments are massively supporting this!

Is it odd that I'm mentally working out how best to tidy the few cables up and mark up the different valves/pipes.

I've already dynotyped the On/Off labels

Epic work and dedication by all.

What are those temps in old money? 90f is bob-on for us

32!

At school, the pool wasn't heated, they'd let make us swim at 10c/50f, if it was sunny, 7c/45f was allowed.

29C or even 32C seems completely bonkers! I used to do a lot of natural river and lake swimming and as a general rule if the outside air temperature is 10C or above you will be fine in the water after the initial Cold Shock Response and your body adjusts - this is without a wetsuit by the way so comparable to using an outdoor home swimming pool.

At this time of the year with a fairly steady outside air temp 15-20C most days you won't need any heating for the pool at all. It'll still feel baltic cold when you first get in but after a few mins submerged you'll find it's actually quite pleasant. You can reduce the CSR by splashing and rubbing the water all over your skin beforehand, particularly your upper body.

To swim in 7C as mentioned above without any suit is very risky. High risk of hyperventilation and blood pressure/heart problems which can quickly get you into difficulties.

My kids won't swim in less than 28/82. That's what mine is set to.

I assume you've been given the routine on valves and how to backwash etc? With that number of valves it might be worth labelling them very clearly.

Similar story here, if its anything less than 28 degrees they won't get in it!

Air source heat pump doesn't use a st ton of electricity though, so i don't mind so much

My mother in law keeps hers at 90. They have seen 110 when they left the heater on. That was unbearably hot.

Rainbow 320C in line chlorinator... that will be perfect on that size pool! Once it's set to the right level, will make routine maintenance much easier.

I lived with the in-laws in Spain for a while and their (unheated) pool would achieve 32 degrees just through the suns radiation heating it. The initial plunge into it was ectasy. We had to cover it every night though with an insulating sheet to stop the heat dissipating out as it would be 26-28 the next morning and take too long to warm up again. With the sheet on it would only drop to 29-30 by morning.
Of course, this was when it was knocking on for 40 degrees in the sun...

Morning update, paving going down nicely and pool starting to clear now:





Boiler is being connected this morning so we will be starting the heating later today. Main thing for me is to get the rubbish off the bottom of the pool.

Over fill the pool and then just vacuum to waste.

The really fine muck is too small for the filter so by doing a normal vacuum it'll just end up in the pool again and make your water all cloudy.

I'm sure your pool guys will take you through all this.

Like a lot of things in life everything seems really complicated to a novice but after a couple of seasons you'll soon become a pro and get to know what to do and when by gut feeling. Alternatively get a pool maintenance man in (young chap out of Pepsi advert) which will keep the Mrs happy.

I spend about 20 mins a week keeping my pool open during the season once it's all up and running.

I might've missed this but presumably a project of this scale needed planning approval?

I think that he meant the air temperature was 7c rather than the water temperature. Still pretty nasty. We used to have an unheated above ground pool at school and that was blooming freezing (and the footbath thing always used to be full of dead leaves and frogs)

Somewhere between 27 and 29 degrees C is probably about right if you want the kids to use it.

No, the water temp. I remember seeing the board at say 48 and always hoping it was cancelled, but we'd end up in it. This was 'only' 20 ish years ago too.

In other news, wife still saying 32's the gold standard, but 30 at a pinch.

Not a hardy breed, my family.
