underfloor heating system with a rocket mass heater

http://www.permies.com

Erica Wisner shows us some of the latest innovation with rocket mass heaters. This time there are two innovations. One is sub floor heating. The heat of the rocket mass heater exhaust is routed under the floor and then outside. The other is heat bypass valve - the heat is the routed directly outside, bypassing the underfloor heating.

The cool thing about this design is that you run one small, hot fire, and it gives off heat for days. And there is no bulk in the building. And this isn't nearly as expensive as other underfloor heating systems.

Erica talks a little about sub floor vs. in-floor heating systems. An earthen floor in a shed is dug out and replaced with a wood floor.

@paulwheaton12 Can you post a follow up of this project and some info on the efficiency of heating the space from below the floor? I live in a pier and beam house and am trying to design a RMH system for it. I have some ideas, but before I put this immovable object in my house I would like to see how this worked. Thanks Paul. BTW....Thanks for visiting The Survival Podcast occasionally. I really enjoy your interviews.

@planot171 If you ask at the forums at permies I might be able to persuade erica to respond.

Would like to see some more information on this project!!! Looks very intriguing to say the least. I'm curious what type of ratios from heater to floor area can be achieved? It appears that your building is about 150 sq. ft., I could wrong but can something like this be done in a building that is more like 400-500 sq. ft. and actually be warm in shorts and t-shirts? How often does the stove need to be fired in order to maintain a nice comfortable interior temperature?

[paulwheaton12]

@tech2480 The experts on this hang out at the forums at permies - look for the forum called "alternative energy" and ask your question there.

@Blackoutx86 rocket mass heaters don't have creosote.

[paulwheaton12]

@DixieDiarist convention wood stoves have problems with creosote. Rocket mass heaters don't.

Hi,

I saw your vid, a week ago, then yesterday I saw this.

(Please search out this video on Youtube.)

"Rocket Stove and Stirling Engine.avi "

I keep getting an error trying to link to the URL.

Can you imagine, (have you imagined) making your electricity (or at least some electricity) by doing something like this? And wrapping some copper pipe around your heat tube, for a heat exchanger to heat some H2O. I imagined building the stove outside your hooch, using your vent system, so that it could be used in fair weather, I'm curious what you think.

Peace

Gill

this is the second video of yours i have come across, paul. really great stuff.. visited permies and read some great info! really interested in homesteading here in maine. possibly subterranean or berming. really like the idea of rocket stoves an trying to find a way to combine modern radiant heated flooring with one of these cool efficient heating techniques.

Thanks

I like!

Obviously this is a much more affordable way to do it...but a lot of newer wood stoves are built to burn the gases just the same as rocket stoves. Nice to see main stream catching up to smarter technology. Too bad they cost an arm and a leg.

Smart very smart on the bipass valve..
