Glenn-
I recollect that you cast your ballast keel years ago, so will this be set
in some kind of bog between the lead keel and the hull's (wood epoxy &
glass) keel?
Seems to me to be a very good idea to be putting such plumbing, if it can be
made to work, in a place where it can be gotten to, if need be. I was
beginning to worry a lot about pipes actually cast into a lead keel.

Getting back to the original post- maybe if there were troughs cast (or
machined) into the top of the lead casting, pipes for heat transfer could be
set in them.

A few thoughts from the barnyard engineer,
Jim

Glenn,
Are you planning to us this as an evaporator?
Matt Colie

No. It will be the condenser. The evaporator goes in the refrigerator.
The keel will be cold enough already. :-)
