Rocket Mass Heater

Is there anyone in or near Washington state that can put me in touch with people who know about rocket mass heaters and could help me present the idea to the county and eventually build one? I'm planning to put in a quonset hut next summer and would really like a RMH in it. The only mason I could find had no experience with them and would only order a kit from Britain - to the tune of about $10,000. Any help from anyone here, for considerably less, would be most appreciated.

Fortunately for you several of the RMH experts live in Washington State. Ernie and Erica wrote the book, and they live in Eastern WA. They currently charge $150 per hour for consultations. But if you told them what county you live in, they might have dealt with that county already.

Matt Walker lives somewhere near Puget Sound. If you buy one of his plans he consults via email for free.

If you are really leaning towards a masonry heater with a rocket combustion chamber, my idea is that Max Edelson from Firespeaking in Eugene is your man. But they say they aren't taking any new projects for 2023.

And, of course, there are all kinds of experts here on the Forums.

Indeed, many experts but how do I know who has good theories they want to try out and who has actual tried and true experience (especially when it comes to dealing with the county)? I will contact those people you have named. Thank you. I hadn't found any actual local people with experience yet. It will be worth the cost to have confidence in the advice. Thanks again.
