"This is the original Bonny 8" Convection Bench Rocket Mass Heaterplans, plus our Operation and Maintenance Manual.
The higher price includes 1/2 hour of phone or email support to answer any questions you may have.
This is not typically enough time to discuss a new, custom design or complete site information (generally takes 3+ hours). It is intended mainly for those who have some building experience, and may have specific technical questions about details like substitutable local materials, exhaust chimneys, and so on."
