Universal answer to designing a rocket mass heater

For those of us that aren't technically inclined but very good at following instructions. What I have is a great room/kitchen/bathroom area that measures 23'x28'. I the ceiling is 14' tall. The insulation is R-45 in the ceiling and R-25 in the outside walls. Can someone tell me where to find plans to build a simple stove capable of heating this area? I was looking for a materials list and plans. Is something like this readily available?

Look for Ernie and Erica Wisner. They have complete plans and are the moderators of the rocket stove forum. Click on the forums button at the top left of your screen, then scroll down to the energy section. Moderators of each forum are listed on the far right.

Perfect! Absolutely what I was looking for. Thank you for your help.

Kitty B. : Both Ernie and Erica are both Currently at the Rocket Mass Heater innovators gathering ! I suspect that they will not be spending a lot of time tending to their
E-Mails

You can look at the plans they have posted up on their site by going to ernieanderica.info/shop, The entire site is crammed with useful information about RMHs
and various hobbies and skill sets, do take your time to at least look through the various sections, if only to have an idea of where to go for more information .

I am not a social secretary for E & E, but I do think this gather will be both very productive, and also extremely exhausting, it may take several weeks for them to be
back on a '' More or less'' normal schedule ! For the good of the Craft ! Big AL

I don't follow these things. I thought Erica might be home baking and Ernie might be fishing

How big of a Rocket Heater would I need to heat a 20'x20'X6' Walipini? As I am in the planning stages?

That depends on your climate. Where do you live, and what planting zone are you in?

For some reason I had a brain fart there :0 kind of hard to give an answer if you do not have the fact Zip code 80808, Calhan CO is in USDA Hardiness Zone 5a: -20F to -15F. Using updated climate data through 2010, 80808 is in the Plantmaps Hardiness Zone 5b: -15F to -10F. The average first frost in 80808 is between September 21 - 31, while the average last frost occurs between May 21 - 31. 80808 is part of Ecoregion 26j - Foothill Grasslands. 80808 averages 1 - 7 days per year where the temperatue exceeds 86°F. The average annual high temperature in 80808 is 61°F and the average annual low temperature is 30°F. The average high temperature in July (Summer) is 81°F, while the average high temperature in January (Winter) is 41°F.
The area is pretty flat, the Walipini will have a North South orientation with about 1'foot or so at the lowest end above ground roof will be 2 layers of 4 mill plastic Semi Transparent with apx 3/4" dead air space. The door will be home made with 1/2" plywood and 3/4' Styrofoam insulation and sealed as much as possible to prevent drafts. of course I am open to any suggestions or more questions on my project.
