We made one in Miami from black poly pipe on the roof of the house. Lots of
sun. Used the pool pump to circulate the water up and down so there was
only friction pressure. Kept the pool nice and warm. However, I don't know
that you have enough sun except in the summer. I doubt you would have
enough in the winter, when you would want the pond heated. We have also
made them from old refrigerator cooling coils from the back of old units.
Don't know of any specially made for ponds.
