I ran across this heat exchanger that is intended for beer making -- looks like
it might work in some solar applications? Its single wall.
$09 and free shipping!!
There is also a high temperature, magnetically driven 7 gpm pump on the same
page for $29 -- unfortunately its AC.

I Never thought of using my wart chiller as a heat exchanger. A
simpler version is a 3/8 tube inserted in a 5/8 garden hose and eneded
with 1/2 inch ridged pipe & tee, with a cooling water out the leg of
the tee, a modified adaptor the 3/8 tube emergers. With 70 degree
florida water this chills boiling wart (pre fermented beer) to 75
degrees in 24 feet.
