Books:

The Rocket Mass Heater Builder's Guide: complete step-by-step construction, maintenance, and troubleshooting.

 https://newsociety.com/books/r/the-rocket-mass-heater-builders-guide?aff=8
This is the book we wrote after ten+ years of working with rocket mass heaters in conventional residences, and seeing many builders and owners struggle with the same, preventable problems.  While there will always be room for innovation and improvement, there's no reason to repeat well-documented errors.  With this guide, DIY and professional builders can start with a workable, replicatable design, with proven dimensions and proportions, and eliminate a lot of expensive and dangerous guesswork.  The chapters are arranged in order for DIY owners: getting familiar with the concept, seeing examples, assessing your space to plan your own project, gathering materials and tools, setting up foundations and chimneys, and step by step construction for our most popular J-style fireboxes including brick layouts, photos, and diagrams.  Operation instructions follow, with a generic owner/operator manual with fill-in-the blank prompts to document the details of your specific project.  The final chapters in the main section cover rules of thumb, clearances and building codes that may apply in specific jurisdictions, and extensive FAQs with troubleshooting notes.  
Appendices cover bonus topics of interest to many readers: fire science educational activities (a mini taste from our Art of Fire booklet, below); permitting case studies and alternative building code language; some engineering math and chemistry in case you want to really push the limits on what's already been done before. Some of the most promising and innovative designs have their own appendices - like Peter van den Berg's batch rockets, Tim Barker's hot water heating, Wheaton Labs' version of outside combustion air, and an exciting but ill-fated experiment in off-grid pellet hoppers.  The whole package weighs in at 400 pages, including a color insert, and we narrowly avoided having to charge textbook prices for the tome.  
Retails at $39.95, sometimes available more cheaply on warehouse sites like Amazon.  The link below takes you to our publishers' website, where we get the best royalty/commission on each sale.  

    
The Art of Fire:

This book is based on our Fire Science Theater evenings - at least, the parts of that classic campfire evening demonstration that we love to share at every event, no matter whether the main course will be an installation, fire fighter recruit school, or just a marshmallow roast.  It covers the fundamentals for safe, effective fire tending from hearth to ashes.   Includes safe hearth setup, tools and storage, fire layouts, heat transfer, extinguishing tips, along with caretakers' tips for particularly clever stoves and campfires, and cultural notes. 

It was proof-read by two high school teachers (one current, one retired), reviewed by former scout masters, and trimmed down to the best, safest, and most useful tricks that are worth sharing in any region.  Our intended audience is adventure-minded adults and curious children of all ages; our editors were asked to keep the average Scout troops' penchant for mayhem in mind.  Consider stocking copies for your camp store, ski cabin, or fireplace-equipped rental (optional damper-instructional bookmarks available with autographed copies on request).  
  It also includes not-so-basic tricks and ancient crafts that have delighted experienced back-country mule packers and Alaska fisheries veterans.

    Does NOT cover how to build Rocket Mass Heaters or other permanent installations - this is our clever-campfires-for-everyone book.

The first Cob Cottage informational booklet about RMHs was a photocopied pamphlet, "Rocket Mass Heaters to Heat Cob Buildings." This has long been out of print, and has been replaced by the following titles.  The 2005 Evans/Jackson book is sometimes referred to as the original book, and sometimes as the second edition by those familiar with the older pamphlets/booklets.  In 2015 Evans and Jackson produced a third edition, with contributions from many worldwide builders including ourselves.

Captain Ron with a finished driftboat

Coming Soon: The Poor Man's Driftboat (original design by Captain Ron Wisner), approx. 20 pages.  
A 15-foot boat for pickup or trailer launch, built with 4 sheets of plywood and assorted small lumber.  
OK, boat fans, it's been "coming soon" since 2014, because Ron wanted me to build another one to test the plans, and I said we need a beta tester who has neither written these plans nor built hundreds of boats already.  
If you'd like to beta-test the current version of these plans, and help us get the final draft ready for prime time with a few extra photos of your own driftboat project, please contact us at questions@ernieanderica.info


 The Fine Print:

Items purchased here are intended for noncommercial, personal use (except as noted).  We don't mind if you show your copy to friends, or host a living-room movie night with the DVDs, but please do not share files or print additional copies without written permission.  

Ernie originally wanted to say that each plan set comes with a license to build one item.  (Like signed and numbered boat plans).  I'm not prepared to enforce this rule in all cases - these are grassroots heaters, and we've had marvelous 'customers' who swapped hand-carved wooden tools or their grandmothers' sausage recipes for a single digital copy from economies that made online payments impractical.  If they can replicate their passion by passing the craft on within their communities I'm all for it.  But lack of cash on your part, or in your community, does not excuse piracy, nor does it automatically create a charitable obligation on our part.  We have pro-bono options for both standard and custom project consulting, but you have to ask.

Please seek prior written consent for commercial or public purposes such as sharing online, distributing copies to paying students, or contracting to install multiple heaters from one set of plans.  
Teachers may always use purchased copies, or a few pages of photocopied excerpts under the 11% for education rule; we and our publishers offer wholesale rates by arrangement.  
Builders working for clients can purchase, or have each owner purchase, a set of the appropriate plans for each project. If you no longer need our plans, you don't need to keep purchasing them. 
If you need to change our plans substantially, please allow 30 days lead time for a private consultation for your clients to ensure an appropriate, safe, and complete set of alterations can be recommended.  Always document any changes to the original design drawings when handing over the project to the owner.  We are happy to consult on design goals, troubleshooting, or documentation for projects.
   We love to support skilled regional builders.  If you work on masonry heaters or adobe, host workshops or install heaters and ovens for clients, or have the ability to fabricate or source useful custom parts like doors, cleanouts, and barrel/bell caps, please keep in touch and ensure we know your work.    

We accept PayPal, personal checks, cash, money orders, and well-trained firstborn children.  If the links above don't work for you for any reason, please contact us at Questions@ErnieAndErica.info to get your PDF or paper copies.  (If you are expecting a download link, please check your spam / bulk mail folder first.)

If you like these drawings, but want something a bit different for your situation, please contact us.  We have a small selection of 'draft' plans, for projects which have not yet been proven by a full heating season of use, and if one of these fits your project we usually sell them for $20.
We can also draft your custom design, as a custom project outline consultation.  (See below.)

Free Downloads:

These printable downloads are suitable for workshop flyers, starting a conversation with your buddies or building experts, or just sharing inspirational post-cards. We also have a more detailed flyer available by request (suitable for initial meetings between owners, building professionals, and local officials).

*Custom Design Consultation:

Please see http://www.ernieanderica.info/wisnerresources for current rates.  In most cases, we will provide 2 to 5 hours to fully understand your situation and goals, recommend the most appropriate technology for the job, and sketch out a basic floor plan.  Many of these are variations on plans we've done before, and we may pull reference diagrams or whole plan sets from our library for your convenience.  If we don't think our favorite technologies will be a good fit for your goals, we'll recommend a different approach, and refund any unused portion of your consultation fee. 
Projects that are way outside the parameters of past success may require substantial prototyping and engineering, with necessary additional costs.  This includes most hot water, steam, portable, alternative fuels, and buildings substantially taller or deeper than a typical 1 to 2 story residence.  
    We are willing to prototype experimental designs on our test-beds, at cost of parts and labor, or with expenses-paid travel to your location.  We reserve the right to refuse any project at our discretion.
You'll get more value from a private consultation if you've already done your homework.  Visit the wood burning stove forums at permies.com, read the Rocket Mass Heater Builders' Guide and take a look at our site planning page before we begin our consultation.  All advice given through the permies.com forums is free, and if you have an extremely worthy but low-budget charitable project we may be willing to arrange pro-bono-publico consulting via those public forums.  Other good technical discussion sites include donkey32.proboards.com, and batchrocket.eu.  
Parts and Accessories:
The major mass of a rocket mass heater is literally dirt cheap, but most builders buy at least some insulation, and some purchase all-new standard parts such as firebrick, stovepipe, etc. The following links may help you find them.

Parts in a typical project:

Barrel
Ducting or stovepipe
Bricks (firebrick, red clay/recycled brick)
Earth (clay, sand, quarry fines, rock, subsoil, fill dirt)
Perlite (or other high-temp insulation)

Hardware / fittings (cleanout cap, tap screws, tape, chalk, gasket, foil tape)
Fiber or straw for cob casings
Decorative materials (tile, mica, pigments, facing stone, stove enamels, etc)

Tools:
Shovels
Wheelbarrow
Tarps
Buckets
Masonry tools (trowel or float, brick-set or cold chisels)
Tape measure, level, etc.

Polished stainless barrel
Barrel / Bell: We have a design contest open to the public, to create a 'better' bell for the heater.  It needs to works well (support downdraft temperatures and remain airtight) and look beautiful.  Many noncombustible trim options can be purchased at hardware stores, such as figured metals screens, tile, and engine-block paints, but all of these may affect heating performance to a greater or lesser degree.
  For standard steel shipping barrels, try scrap dealers and junkyards, feed stores and commercial processors (e.g. a local maker of soap or shampoo), Craigslist, or your local Jiffy Lube (smaller grease cans, often used as shop trash cans).  Steel buckets for pocket rockets can often be had at paint stores, mechanics, or fireplace shops (furnace cement).

Two more versions of the barrel: (reclaimed barrels, polished and oiled.  The copper version is simply a flat sheet of copper wrapped over the steel barrel.)  Stainless steel barrels can be purchased online for substantially higher costs, but be advised they don't radiate heat as effectively as weathered steel.  DO NOT use aluminum (e.g. old kegs), plastic, or other materials that melt before 2000 F.
Simple copper wrapped barrel
Oiled barrel with cob and tile topBarrel ideas
  
Firebrick, stovepipe, through-roof fittings, and other new stove parts: Local fireplace shops and woodstove installers are great.  We liked Ludeman's fireplace shop in Beaverton, OR; and AlJu in Omak, WA.  Most Ace Hardware, Home Depot, and other hardware and farm stores in cold climates will carry fireplace materials.  It's hard to find a small fireplace shop we don't like, so far.  You meet the nicest folks, who are passionate about odd things like boiler insulation.

Ducting, reclaimed brick, tile, and other recycled building parts:
the ReBuilding Center, Portland OR;  Habitat for Humanity's ReStores across the USA;  comparable local sites like NZ's SuperShed and the Kiwi Swap website.   Hit Craigslist early and often, and don't be afraid to post in the 'Wants' section.  Expect to pay for metalbestos chimney parts and other spendy-when-new items, even if only at 'scrap metal' prices.  Ask scrap-metal dealers and haulers about sources, and whether you can buy from them when they get a new load. 
Please feel free to recommend other sources you love.

Insulation: Perlite is the most widely available, usually bigger farm, garden, building suppliers, concrete suppliers will have it.  Horticultural or building grade are both fine; just avoid those "enriched" with fertilizers.  Try to find 4 cu ft bags, nothing smaller than 2 cu ft, for the best prices.  Vermiculite is a second choice (you need twice as much of it, and it is not as versatile to make weight-bearing mixes such as floor insulation). 
Refractory insulation: We have had good results with a blanket or batt-type refractory insulation such as rock wool, kaowool, superwool, etc.  Kiln brick (the lightweight stuff that you can carve with wood tools), or refractory insulation (Durablanket, Duraboard, Fibrefrax).  Fiberglass is not suitable for the heats involved.  Some Australian builders like to pull superwool from the engine hood insulation of wrecked commercial trucks.
Refractory insulation options can be found at fireplace shops, ceramic suppliers, a good masonry supply (these insulation materials are used to back insulated chimney liners and fireplace throats).  Rock wool, one brand is "Roxul" high-temp products including a greenish-grey granite batt, is sometimes sold as building insulation (especially in Canada and bordering states in the USA).  If time allows, we sometimes order directly from the makers online.  (Western Industrial Ceramics in Oregon and California has been very helpful in the past; there are similar regional suppliers throughout North America for ceramic-fiber blankets, boards, felts, and other products.  
Pottery shops like Georgie's in Portland, OR, or Clayscapes Pottery Inc. in Syracuse, NY, may have a good basic selection of bricks and insulation for kiln making, or be able to order from their catalog suppliers.  

Natural plaster colors, tints, and additives: Our favorite is Georgie's Ceramic Supply; they cater to hobby potters and have a lot of naturally-colored clay, extenders like grog or mica, and non-toxic clay-compatible paints for surface murals.  Avoid glazes as they may be toxic, and rarely tint well if unfired.  Also a great source for kiln brick, weird tools, and refractory materials.
The Green Depot has premium ingredients at premium prices; they source natural and recycled decorator materials from Oregon Clay, Ochres & Oxides, and other suppliers. 
Local masonry suppliers will have concrete pigments at a fraction of the price, which are suitable for lime and clay plasters but may not be as 'naturally' sourced.  Also a good bet for lime, high-grade masonry sand, and colored sand. 

You can also take a suitable container to most local hardware stores and get paint pigments sold by the 'squirt' (the ochres, white, and black, they are more heat stable, but you can try other colors if you like).  Ace Hardware and Do It Best stores are run by good local folks in most cases; we've had good experiences in various locations.  Home Despot and Lowes are a crapshoot; you get great expert helpers, and clueless salesgerbils, and have to watch more closely for inferior products.  But the do tend to have a little of everything.  We prefer to go first to the oldest local hardware store we can find, they tend to be awesome, and they will stock the best and the cheapest decent version, no crap.
Hardware stores are also good for gasketing, masonry tools, tarps, a wheelbarrow, grinders or tinsnips, ducting screws, buckets, and other miscellaneous ... hardware.

Refractory ceramic insulation: You probably don't need it, but it's fun. 
We have had good experiences with Western Industrial Ceramics at their Tualatin, OR location (they cheerfully do business with anyone: aerospace industrial giants, foundries, pottery studios, amateur glassblowers; and they can custom-cast refractory parts at reasonable rates.)  Many of the standard materials like board, brick, and felt can also be found locally - search for suppliers under foundry, masonry, industrial, ceramic/pottery, and woodstove/fireplace.  LaGrande Industrial Supply Co (foundry specialist), and Masons Supply, are two examples in Oregon.  Both have treated us right when we know exactly what we need; ask for a catalog or sample if you're not sure.
Industrial suppliers generally cater to tradesmen, not retail, so expect early hours, and don't be high-maintenance about small orders if you can help it.  They often stock superior masonry tools, powdered fireclay, kiln brick, fire brick, gasketing, sand, perlite, etc., sometimes at lower-than-retail prices.  If they sell only to licensed contractors, you can ask a tradesman friend to pick things up and offer a percentage for their trouble.
