You might consider, if you haven't already, sending it both
through the center and around the outside in a split flow. Set it
up so the skirt is a little restrictive and the center path is the
preferred path, then incrementally block the center path to yield
various percentage split flows and the lowest net stack
temperature.<br>

Hope that's not to expansive :)<br>

From experience, having the heat go through a single
pipe/chimney in the center of the water tank is much better than
having the heat go around the outside of the steel drum. And
it is much less expansive.<br>

has a ballpark estimate for heat transfer efficiency w/ and w/o
using a pot skirt attachment. The hot water tank will be a
55-gal steel drum, so I think the setup is pretty analogous to a
cookstove setup, just bigger.

<div>FYI, the char from the water heating setup will be used
in arbor-loo style modular composting toilets. This
infrastructure is being installed during a rambo
design-and-build sesh for my wedding on a farm in rural
Appalachia (USA), but will be used continually by future
events at the site. Cool, huh?!?!</div>
