I was thinking of wood because some of this bench would be on a wood floor.  That might help protect the floor.  Plus, I have a pile of 2x4's.

Thank you everyone, especially Erica, for your valuable and helpful suggestions.  Given time of the essence I am going with Erica's pocket rocket suggestion for now, and abusing credit to have conventional boiler installed--urk-- but no freezing.  Retrofitting a mass stove to a 100 year old house isn't going to be a fast project, I am seeing.  Again thanks!

Hang on my head just exploded, too much info, m-u-s-t  s-t-a-r-t  b-u-i-l-d-i-n-g. OK. I'm getting most of it, I built a pocket rocket and cooked some food with the kids, and I really want to heat with thermal mass. (By the way the pocket rocket kicked butt, its my new camp stove!) I may not be able to use a rocket thermal mass in my current house but I think as soon as I can I'm going to start testing in the garage. One problem about that is the gas water heater. Pretty sure I'll need to take that sucker off line before I have open flame out there! This is really important stuff, thanks for sharing your experience and wisdom, and middle of the night lucubration. Wait a minute I'm doing the lucubrating! Narf.

You can burn an open flame all day and all night around yer gas water heater... You just don't want any flammable fumes (like from gasoline) getting near your open flame gas heater...

Oh yeah ,  unless you have a leak in yer gas lines.. In which case.......run!

Hello all,

Something that needs to be considered when adding a fuel burning heater to a room or house with existing gas appliances is combustion air...you could light your stove and have your water heater go out, cause the stove is sucking up all the available combustion air! Or worse, have the negative pressure pull flame into the house from the gas water heater with serious risk of fire...I kid you not, I have seen it happen!

Happy heating!

Bud

How tall can the flue of a rocket stove be? Can I have a rocket stove in the basement and still run the stack out through the second story?

I built a rocket stove, tried to vent it out my basement window (BIG MISTAKE) Yes! it worked great when it was rocketing! But while trying to get it going and when it quit, blow back massively into my basement! I have since figured I will patch into my chimney, this way when I am starting the stove and when it slows or stops, there will still be a draw and no smoke will fill my basement (wife was pissed)
I built my stove with 55gal drum, refractory cement, galvenized exhaust connected up to my cermamic chimney. Time will tell
 
I just had the craziest dream. This tiny ad was in it.
