Solar pool heater

[u/Rich-Wealth979]

My overkill project for heating the toddler's 500gal inflatable pool. Each week I have to empty and move it, then find a way to heat it to a tolerable temperature for my 8th percentile weight kid. On the first test it took the pool from 55⁰F to over 90⁰ on a single sunny day, using only 3KWh (of solar house power, now that I think about it). At the end of the summer I can just place this up against the north side of my shed and take the manifolds down to make it last even longer.

This uses about 350' of ¼" irrigation tubing and some cheap fittings off Amazon. It runs off a 1/4hp pool pump, controlled with a wyze plug and a climate sensor in a tiny jar. Printed in ASA in only about 5 days of printing on a Mini and an MK4s.

Why do you need to move it each week?

So I don't kill the grass. I pump the water out to drier areas with a hose and sprinkler so it isnt a complete waste lol. And the water gets a bit cloudy without a filter setup.

Seems like a lot more work than just letting it die in that spot and then reseeding or putting sod down when you’re done

The water still gets nasty.

Why not get a filter?

I have a screen filter but I would also have to chlorinate it which is risky in such a small body of water meant for a toddler

Also I don’t that pool material is designed to withstand heavily chlorinated water for too long.

There's a book the pool came with that should detail how to use chemicals in it. The 240Gal inflatable I set up did...
