“Chelle Lindahl, who lives in an off-grid home near Canton, NY, speaks about the rocket mass heater she uses to heat her home. She also discusses other aspects of how she tries to have a low-impact lifestyle.
Rocket mass heaters (RMH) are low-cost, high-efficiency wood-burning stoves that typically consume a fraction of traditional stoves. Chelle’s RMH was built in the fall of 2012, during a workshop led by Ernie and Erica Wisner – who are arguably some of the most knowledgeable people in North America when it comes to RMH. You can check out their website for more info.”
(There’s a good RMH drawing on their website.)
