Ernie was on the research team for the Second Edition. Now he and his wife Erica are helping make “Rocket Mass Heater” a household term. They teach workshops all over North America, and sell plans as well as their books The Builders’ Guide and Art of Fire. In their eighth year of Rocketry together, they have built, supervised, or fixed installations in a wide variety of buildings. They have advised on all six inhabited continents and on devices including a tropical hardwood kiln, coal-fired cooking and heating stoves for Mongolian families, and larger heaters for schools and community buildings.

The foremost builders and educators of this stove, Ernie and Erica are getting ready to publish The Rocket Mass Heater Builder’s Guide. It will offer a specific instruction and recipe for a specific stove, with measurements and materials lists, to help the reader build a tried-and-true stove that has been working for several years. Help them fund the first round of printing in their Kickstarter Campaign.
They have an excellent article on their site about the efficiency of this stove. Clearly stated with stats to back it up. De-mystifies some of the outrageous claims: http://www.ernieanderica.info/rocketstoves/rmh-efficiency
