Well it's OK for many of you good people, you are lucky enough to live in a climate where your pools warm nicely throughout the day But for me, being stuck in Blighty our pool is further north than all the US states except Alaska so the amount of solar benefit (even with a solar cover) is not brilliant.
Last year we actually managed to gain a 5 degree advantage using a solar cover during the hotest part of the summer and it even got warm enough to get my 2nd daughter in the pool last year. But this year I would like to try and get more heat in to the pool so I started looking at heating options including gas, oil, solar panels, heat exchangers etc but I need to heat the pool on a low budget and all the other options are quite expensive
So, here's the challenge I have set myself.
To design, source and build a self contained fully operational and effective solar water heating system for the pool without spending a single penny on any materials at all.
My design concept is to capture and convert solar energy in to usable water heating by using four old radiators donated by my sister who recently had her central heating system replaced.
The four radiators will be mounted on old chip board and wood panels etc which I am collecting from various sources for free. I will then connect the radiators in series using old pieces of copper tubing, washing machine hoses, old tap hoses and plumbing fittings I have lying aroung in the shed and will paint everything black in order to (hopefully) attract the maximum amount of solar energy. Then the radiators will be encased in common polythene sheet to provide an additional 'greenhouse' effect.
I'm looking to mount the radiators on a sun facing wall at an angle that shound maximise the suns rays.
Will it work? I have no idea.
But I'm looking forward to playing around with it and finding out. If it doesn't at least I have lost anything.
As things kick off I will try and post some pics so you can all have a good laugh at the endevour.
Don't build your hopes up, I know I certainly am not. It will just be interesting to see what improvements (if any) it makes
If anyone has any ideas, suggestions and criticisms then pease feel free to chip in as I'm totally open to comments good or bad
