starters, you are talking of aquiring about 200 KWh, which is quite a lot of
power.</FONT></SPAN></DIV>

assume you are talking about black poly and the pipe has a capacity of 70l.
Still water inside it can get hot but it takes time and you will have to, in
effect, empty and fill it 500 times just to pass the pool through it
once.</FONT></SPAN></DIV>

<DIV><SPAN class=100000315-08112010><FONT face=Arial color=#0000ff size=2>You
might be better off trying to lay 6sq.m. of black poly sheet out on the
pool cover and squirting the water over that. At least 100% of it will be
looking at the sun.</FONT></SPAN></DIV><BR>

<DIV>Can anyone tell me if I am likely to gain the 5°C or so that I would
target?</DIV>
<DIV>If we have power I run the circulation pump from 10-13h. 100m
of a 3cm diameter pipe would have a surface of around 3 sqm. How do I
assess how much this can heat a 35000 litre pool?</DIV>
