Fireplace waterboxer

[Mtn Fire]

Hello all,

Has anyone out there designed an advanced wood stove/fireplace/gasifier with firebox/secondary burn/exhaust pipe immersed in 500 to 1000 gallons of unpressurized water storage for whole house hydronic heating? Unit would be located inside house for aesthetics and ease of operation.

Ideas? Designs? Future U.L. listing challenges?

thanks,

Alex

Yes, if you have a large area to house it.

And it can exhaust into a metal trash can or 55 gal drum due to it's low stack temps.

Yep. That pretty much the Garn concept in a nutshell.

And it is UL/CSA approved.

That's what the firetubes in a gasification boiler also do. If final exit temperatures of the pipe (flue) gases are below the condensation temperature, then the design will have to account for condensation of water vapor and other unburned gases, trapping of fly ash and other particulates in the condensate, and easy cleaning as these accumulate in the exhaust pipe. Burning wood is a lot different from burning natural gas. Essentially the only by-product of NG is water vapor and CO2; not so with wood.

I've seen something that is aesthetic but it doesn't have big storage:
