I am thinking about putting in a large solar water heater.
I am plumbing the new pool in the next couple of weeks so I need to know if I have to put in separate pipework
for the solar or if I can use the main pump and line.
The plan is to put in 2 or 3 times the surface area of the pool (28sqm) in black pvc pipe; about 90sqm, coiled on a piece of ground about 6ft higher than the pool/pump and about 30ft distance.
I need to find out how effective this kind of larger installation would be in heating the water in winter.
The average daytime winter temp is around 60F and night time around 50F: no snow, night time frost is rare and light, typically winter daytimes with full cloud cover.
If the benefits of putting this size of system would not extend to keeping the pool sufficiently warm in winter then I should really only put in sufficient pipe to extend the shoulder seasons.
