Thanks, Reuben, for that link.
Yes, that's the idea. And there's three different models!
I hope they can really promote it well, and, that it is accepted by the
Insurance companies in Aussieland.
I suppose there is no hope of it being certified by UL or CSA underwriters?
What I like in general, about this way of water heating, is that it does
not interfere with combustion. It doesn't reduce combustion air
temperatures at all. Yes, it will reduce flue gas temperatures. But all
combustion, both primary and secondary burn, would be completed by the
time the gases exit the stove and enter the flue.

made from heavy stainless steel, and filled with water. The water
column is three feet high, inner flue is six inch diameter, and the
outer tube is eight inch diameter. Thus there is close to five sq.
ft. of surface area, of the inner flue pipe in direct contact with
the water. The heat exchange area is functional.
