Common sense versus technical knowledge in boiler design

I haven't read everything on your site about this topic so may have missed this suggestion: what would be the expected smoke problem from an outdoor boiler if it was used to heat water in a large storage tank, and the stored heat then extracted over several days while the boiler was off and cold? This would allow the boiler to be run hot and (relatively) clean, reducing if not eliminating the smoke problem.

I have considered building one of these myself for a Panabode house I'm putting on a 5-acre property I'm moving to in the next few months; the shop is under construction right now. I build pottery kilns and assay furnaces for a living and therefore am competent working with firebrick making chambers that stay at over 2000F for months at a time for many years; destruction of these occurs from corrosion of the 70% alumina firebrick, not from heat. So would I be able to build a firebrick combustion chamber with the exhaust gasses passing through a conventional many-tubes-in-a-tank heat exchanger and achieve a clean-burning system?

I've learned over the years of burning with wood that efficiency is simpler to achieve than it would appear at first glance: buy top quality, keep it smaller and burn it hotter, rather than bigger and cooler. It took me 3 stoves to find that out, finally falling in love with a Petit Godin, which is what will go into the panabode. I bought mine (1979) just before the requirement for CSA testing so it is not labeled, but I have subsequently found that the model I have (3720) was tested and certified and I have obtained the CSA file for it, so am hoping that the inspector sees the world the way I do! We'll see shortly.

This looks like an excellent website, especially to someone who can grow enough wood on his 5 acres to keep himself warm for the foreseeable future, gas prices notwithstanding. It will be fun watching the popularity increase again like it did in the mid-70's, and listen to all the old ideas being re-discovered. I grew up on a farm where wood was the only heat we had, and have always wondered what all the fuss was about! There's a lot more common sense to it than rocket science.
