Well, this does have a little bit to do with woodwork, as my solar heating array is on a timber backing, and supported at the optimal angle by a wooden frame. The array is 50m of 13mm irrigation pipe, laid in a spiral formation on a plywood backing 1m x 1m, and inclined at 25 - 45 degC for here in the tropics, depending on the month.
We get 5kWh per sqm of solar heating each day here in winter, so will probably need a couple of arrays.
What I need is a suitable pump, preferably submersible solar, that will pump water from my pool, through the array, and back into the pool. I am not sure if solar pumps can push water over 50m length, with a head of 1m above the pool deck. The pool is 2m at the deepest part, but I would be taking water out from the shallow end.
I know that you are all quite practical, so any helpful comments and suggestions please?
It would have been ideal if I could have got it to work as a siphon, but that is not the case. Something to do with hydrostatic pressure between intake and outlet in the pool being inadequate. ( not enough height?)
regards,
Jill
