Hi Permies. I know some of you have been following the wood stove Design Challenge and know that I, with my Walker Stove, and Dragon Heaters are finalists who are bringing rocket mass heater technology to the competition. I thought I'd show you guys what I've been working on all year and am bringing to the Challenge.

My heaters are stand alone heaters that can be set up in minutes, and are capable of being connected to a thermal mass of your choosing, whether it's a cob bench or a brick bell, or any number of configurations. One of the things I think Permies will find most interesting is the risers, which I have available now if anyone needs one for their next project. I hope you like it, I've worked hard on this over this last year. Don't worry, I still intend to share as much info as possible via forums and videos. I just had this idea burning me up and had to see it through. Anyway, it's here....

Matt, I was unable to add a comment to your site or view the video. No keyboard comes up for the required name and email tho it lets me type the comment. Then I get an error message.

Thanks for the feedback Bill. I'll see if I can sort it out.

Matt, found a workaround and got video to play by clicking on links, then youtube address showed up.

Wow! Okay Matt, how much would a version cost to heat my 712 sf basement? I would cut registers to get some heat upstairs too.

I love that you can load a batch, set it and forget it. How does the window withstand 1200 f+ heat?

Could I exhaust out a basement window or does it need a dedicated chimney?

Bill

PS. Maybe i should just bring this marvel upstairs and heat the 1100 sf 2 story living space. What are the btu/hr ratings? Emission ratings?

Bill, thanks for the enthusiasm! I'll just touch on a few of your questions here since others may be wondering as well, but if you'd like to talk in more detail, please email me, or pm me your email address.

I'm just starting this whole process, so currently the stoves are built on a custom basis. Pricing varies depending on configuration, but is comparable to mid range wood stoves.

The batch loading is great, but keep in mind that it's still burning full tilt, so time between feeding isn't that much different than a J tube rocket mass heater. It will need feeding every 45 minutes to two hours, depending on the fuel. It should be coupled to thermal mass for round the clock heating.

The window is rated at 1500° continuous, but keep in mind that it's excellent at shedding it's heat, so it never really gets near that temperature.

I would recommend a dedicated chimney.

The basic Efficiency model uses a core designed by Peter van den Berg, who has done lots of testing and published results over on Donkey's board. I believe I saw a thread where you were directed towards his results already, so perhaps you've seen the numbers. If you are going to be in D.C. for the challenge, we will get another round of numbers there, and I hope to have full lab results available in the not too distant future. Thanks again for the questions and interest!

Oh man Matt, you and the Dragon Burner gang in the same room, soooo cool! Can't wait to explore the links and info and such. Best of luck to you, it's so important for regular wood stove types to see this paradigm shift!

So many folks I talk to about this just glaze over. They need guidance and our patience...

Keep up the great work~p
