Anyone ever experiment with anything like this http://www.woodheat.org/report-bob-modify.html (http://www.woodheat.org/report-bob-modify.html)

Some stoves could benefit from it, others would not.
That's been a popular article for a while... It still doesn't compare to a good running gasser

Just curious to see if a non-gasser has played around with using firebrick. Nothing as extreme as that but maybe a half wall before the last big baffle to stop heat from escaping the firebox as fast and also direct the gas flow better. Also seems the firebrick would retain alot of heat giving it off slower which would give you longer burn times.

The gassers I carry all have a lot of firebrick, they store heat, but it's not transferred to the water really, it's designed to store heat so the wood will reignite, you must have fuel, air, and temperature of about 450 to make wood combust
-
Very interesting modification. A quick look online shows some pretty steep prices on the fiberboard. I could never save enough wood to make it worth while.
-
Ya, I looked it up also. The fiberboard is def out of the question but firebrick is reasonable and might be worth while. Just cant believe that no one else has toyed around with it(in a non gasser).

The inside of my Heiss boiler is lined with refractory cement, looks like the same thing that firebrick is made out of. Is said to withstand up to 3000 degrees, have not had a chance to use it yet.
