How to Read Erica's Plans and Diagrams:

Most of these plans are done using standard architectural drafting, old-school style.
(I was the last class to learn conventional pencil-to-photo-print blueprint drawing, using a real old ammonia light-box, before my architecture department got computers.  Ah, the good old days.).  

Any general builder, framer, mason, or engineer should be able to read these plans quite easily; the age of computers hasn't changed the blueprint language that much, although we now print them in a wider range of colors.  
I use a lot of 2-dimensional templates and a standard color key for my more recent work.
So fire bricks will always show up the same size and color (beige) and smaller building bricks will be represented in their own size and color (brick red).  Cob is brown, wood trim is light caramel (like Doug fir or pine heartwood), concrete and cement-board will be grey, non-combustible insulation will be light grey or white, or white with a squiggly black line (a symbolic convention for black-and-white drawings).  
Plasters, tile, natural stone, and other finish materials may show in a variety of colors, similar to their actual color.

We occasionally hear some confusion from folks who are used to the 3-d modeling or exploded diagrams more common for mechanics and furniture/cabinetmakers.  
We do include detail drawings with marked dimensions for critical areas like the firebox.  Builders may also want our book the Rocket Mass Heater Builder's Guide for additional notes about clearances, allowable variation, etc Click Here to see the Wisner Builder's Guide at NewSociety.com.

Architectural drafting conventions:
- Projects are shown from top and side views.  
- Studs in the wall are shown as solid rectangles, and windows as lines, as if you'd sliced through the house about 6 feet up.  
- Any cutaway view will be labelled, and there will be a line across the top view showing where we "cut" to give that view.  Arrows pointing toward the line show the direction you're looking from.  
- For the main diagrams, look for a scale key, just like on a map; you can use a piece of paper or compass points to take a measurement off the diagram, and compare it to the scale key.  
- We generally include at least one detail diagram, with marked dimensions, for any critical area(s) like the firebox.

Builders' Notes: These plans give play-by-play details of the project goals, how we designed and built the heater, and whether anything was changed in the first year or two for satisfactory performance.  We don't publish any plan unless its owner has been satisfied with the performance for at least one year.
If this is your first earthen building project or first time using bricks, you may find new terms mentioned in a given plan, like "cob" or "thermal mass" or "fire clay mortar," without a lot of explanatory detail.  Definitions are not hard to find on these forums at www.permies.com, on YouTube, or in the attached "Builder's Guide to MUD".
These plans are already pretty long (the greenhouse one is over 40 pages, showing 3 or 4 different project layouts).  So we decided to focus on the specifics of each project, noting its differences from a "standard" system as described in the Rocket Mass Heater Builder's Guide (Wisners, 2016) or Rocket Mass Heaters: Third Edition (Evans/Jackson, 2014).  You may want to pick up a copy of either book, if you don't already have one.

In our limited free time these days, we still participate on these forums and give free advice to rocket project folks and others.  I will make these premium threads a priority.
If you want to start a whole thread about your project and ask for advice or show the step-by-step, you can post a link to that thread here for others to check out as they work from the same plans.
I will check out those links as my time allows, too.

Baby pictures welcome!

Didn't get what you wanted for Christmas? For January only, Ernie and Erica are dropping the price of this combo package to just $49.50 - for everything.

Limited time deal, not gonna last, people.

Price is back up, but only to $75.  
(These plans individually cost about $20/each, the book prices vary - total value is over $154 for all the materials included here.)

I'm interested in purchasing an individual plan. Should I send you a purple moosage or another way?

Ernie and Erica have their very own forum with all their awesome stuff on it.  Are the plans you're seeking there?

Thank you for making this available. I'm excited to peruse through all the contents.

A question: Here in Korea (where I live), under-floor heating is the norm. So I was wondering, could any of the plans included in the package be adapted to an in-floor design? I can imagine the feed tube being at floor level, the barrel protruding from the floor, the ducts snaking under the floor, etc. Would such a design be ill-advised?

Thanks,
Ted

Tried to figure out where I found the other link, but didn't and it doesn't really matter.  Found the 'Everything Combo' here which just downloaded.  Yay!

I'm deeply grateful for the efforts made to organize so much information.  I'm learning so much so fast my head is spinning and I love it! ^.^  

Today I start experimenting with building tiny models to learn how things fit together and how to follow diagrams.  And there are concepts and terminology to learn and understand.  With benefit of ideas already worked out, I'm far less likely to blow things/myself up trying to figure it out alone.

So thank you Paul, Erica, Ernie, and everyone else I am unaware of who helped..

Good Day folks!

Any chance someone might be able to help me purchase the 'greenhouse rocket mass heater design' or the 'everything' combo which I think includes it?  I'm a Canadian.

cheers

Sorry.

If I could kick one I totally would. Although I'm not sure my leg and foot are tough enough to punt the jerkaroonies to the moon, sadly.

Tx for the reply;)

I'm building a 20x40 greenhouse attached to the south side of my house. Trying to figure out how I can incorporate one of these bad boys. It would be most convenient if I could somehow work it in to the front (to be built) stone/concrete front steps which will be about 5 feet high to the front door, inside the greenhouse.
It will be fully insulated to 4 seasons in chilly Canada. With a full glazed South wall in the front.

I'm going to see if I can attach a pic. My tech-ability could be much improved.
Any assistance would be greatly appreciado!

I want your book!!!🥰

I would like to buy the Everything Combo, but when I click on 'purchase' it just goes to a listing of all the Permies forums. The links to plans on Ernies and Erica's website also don't work for me. How can I actually purchase the plans?!

Lizzie, the purchase button is working as intended for me.  I am not sure what would cause the problem you are describing.  Some questions as I mull it over:

Do you use paypal for other transactions?
What happens when you click this link?

Hi Beau

Thanks for responding. When I click that link it takes me to a page asking if my purchase would require Permies to pay VAT/GST....mystery solved. I am not in the US so imports are subject to GST. Very frustrating as I'm keen to purchase plans and I'm sure Ernie and Erica are keen to have customers! I'll try emailing them through their website, perhaps they could offer an alternative.

Thanks again 🙏

Makes sense - did you see the link paul posted about, talking about vat/gst stuff?  https://permies.com/t/137817/VAT-digital-market
