Help designing a rocket mass stove system to warm up a 26x48 greehouse & design guides

Need help designing a rocket mass stove system to warm up a 26x48 greenhouse. We have saw some diagrams and decided it would be wise to build 2 of the rocket mass stove but addition information would help since we are newbies int he rocket mass stove field.

Definitely like the concept on this picture Ive uploaded!

I triedd to find the boook online I believe is Rocket Mass Stove builders guide! but can't find any traces of it. What would be a good book that will give some design guides?

The RMH Builders Guide in draft form was available on Scubbly, but apparently no longer is. Ernie and Erica have been working on a kickstarter to raise funds for publishing, and the latest info (as of July 2015) is that they expect to launch it in September or October - in other words, hopefully soon, with publication in early 2016. https://permies.com/forums/posts/list/40/40545

Meanwhile, Rocket Mass Heaters (3rd edition) by Ianto Evans and Leslie Jackson is the best available book on RMHs overall. The Rocket Stoves in Greenhouses thread in this forum has a lot of good information. https://permies.com/t/19178/rocket-stoves/Rocket-stoves-Greenhouses-forum-topic

For the size of greenhouse you are looking at, two 8" systems may be the best solution to heat evenly and sufficiently.
