hi iv fitted an above ground pool (in uk)as its cheap and easy to remove if required which i have fitted decking around one side.

i have also built my own solar heating system which works very well which is about 40% of pool surface area similar to following.

at present im upgrading to a separate pump for panels which used to be part of pool pump using following parts because you dont need to run pool pump all day i was advised 2 hrs on a sunny day to filter so expensive to run solar with main pump.
1. chargecooler pump (runs coolant in turbo charged cars after engine switched off)12 volt
2.10w solar pv panel(could do with bigger one but a friend donated this) to power chargecooler pump when sun shines
i will have to build some voltage regulation circuitry to allow pump power at right time and to stop over voltage probs but when done this will run free of charge when i need it most.
my friend has installed an heat pump on his 15ft pool and running costs are about 25% of heating electrically which he reckons was about £400.00 before.
i also installed closed cell foam on pool wall last year like the stuff used under laminate flooring and changed from sand base floor to 75mmm closed cell foam base with foam coving because i found pool lost temperature rapidly overnight and with a sand base it can erode get worms in it etc.
but all in running cost are minimal about 40 - 50 quid chemicals and about 40 quid pump running costs.with about 20 minutes per day in sunny weather cleaning etc
hope this info helps
anthony
ps i have a good source for temperature loggers pc based which im fiting as well to track panel performance so i can tweak position and flow rates which should help.
pps look at castorama.fr they sell pool kits cheap
