Batch Rocket Thermal Mass Heaters

October 11, 2019 - October 17, 2019

$650 – $1300

This is the last of a series of comprehensive workshops in which we will construct a hybrid natural building using many site-sourced materials and permaculture principles. This workshop will focus on inexpensive, efficient ways to heat space and water that you can construct yourself. Learn the essential points to clean combustion. Why Batch Heaters? Differences and similarities between Batch Rocket Mass Heaters and classic, J-tube Rocket Mass Heaters. Learn how thermal mass improves heating and how, with the bell system, thermal mass can be utilized flexibly and easily. Build a Batch Box RMH and fire it!

Each workshop is organized into two parts, the weekend Intensive (Friday through Sunday) will include the bulk of theoretical and practical training, followed by a 4-day Practicum (Monday through Thursday) focused on hands-on building experience. Participants are encouraged to attend both the workshop and practicum for the full experience, which is incentivized by a reduced workshop tuition. Workshops fees include an all-organic lunch and dinner as well as camping/housing options and an early morning yoga class.

For friends interested in going deep we are inviting 6 people to do an immersion through the Natural Building series. This immersion allows participants to attend workshops for free and have all meals provided in exchange for weekly work hours, primarily toward building, but also other supportive tasks for workshop prep and facility maintenance. ​

Lead instructors is Kirk Robert of Sundog School of Natural Building.
