it would need to be metal and the only thing I would trust in the pond would be
really expensive.

however, I found somebody on the Puregold system has used the sungrabber in a pond. I

Well... you could do it like a radiator, in that instead of pond water in
the tubes circulate fresh and have tubing in the pond that gives off heat

their ponds with gas or electric do.... I believe.

remote control switches, look in the Xmas lighting sections of
stores.... unless you're hoping to find a temperature sensitive one, that
could be pricey. ~ jan
