My woodstove has a 2'x2' flat top, and I've often thought about casting
a 2'x2'x2" thick reinforced concrete tile over that with a 50' copper pipe
coil inside. Then again, wood is work, compared to solar heat, and it's
off-topic in alt.solar.thermal, home of "direct use of the sun's heat."

Nick,

My SDHW design has a collector on the roof for summer operation. I simply
elected to drain the system for the winter to keep the whole thing potable, and
use an alternate source for heating in the winter: my wood stove.

I really don't think this is off-topic. I would have to think that
heat-exchanger efficiency is very on-topic.

Especially for anyone planning on a solar collector with an absorbtion plate
instead of fins. One point of contact would seem to be a poor design. Others may
appreciate knowing this in advance, rather than building one and finding the
performance less than hoped for.

Wood is not "direct use of the sun's heat."
