Free Heat Movie
Free Heat is a 2 hour and 18 minute film that explores the world of rocket mass heaters, a highly efficient and environmentally friendly type of wood-burning technology. The movie follows the experimentation and implementation by a team of experts working on various types of rockety contraptions. Viewers will see firsthand the innovative ways in which the rocket systems are being used and developed, and will learn about the many benefits of this technology. Whether for heating a home, cooking a meal, or creating a relaxing sauna experience, rocket mass heaters are a versatile and sustainable technology. Topics include:
The basics of RMH design, build, safety, function, and maintenance. Learn the fundamentals to start your rocket mass heater journey.
A standard, 8 inch, pebble style j-tube
The standard, 8 inch, pebble style j-tube rocket mass heater is a basic, yet incredibly high performing system built inside the solarium at Wheaton Labs.
6 inch cob style j-tube rocket mass heater
A versatile rocket mass heater that you can fit in complicated spaces or small structures like tiny houses made out of cob.
Lorena style rocket cooktop
The rocket cooktop just got an upgrade! The Lorena design allows for the rocket flame to heat the pot directly.
Sauna rocket heater
Uncle Mud's cottage design has been adapted to the sauna at Wheaton Labs. Find out how to make a very efficient rocket heater to sweat it out!
Solar food dehydrator with a rocket assist
We inserted a rocket system inside a solar food dehydrator to allow dehydration during the night or at times of the year when sunlight is scarce.
The Liberator commercial heater
The Liberator is a commercial rocket heater available in the USA, We tested its capabilities alongside Sky Huddleston, the creator of this contraption.
The Gamera commercial heater
The Gamera is a Bulgarian commercial rocket heater available in Europe, we connected a coaxial heat exchanger to add a mass inside the Red Cabin.
We fired some clay and melted some aluminum - a step toward more sustainable ceramics and metal-working.
A scheme to squeeze out a little more efficiency from the already breathtakingly efficient 8-inch system.
Challenges with the 4 inch j tubes
We no longer use 4 inch j-tubes at Wheaton Labs, find out why and the reasons the 6 inch j-tubes are a far better option for us.
If we try to start a fire when the temperature outside is warmer than the mass, we will get a cold plug. As the fire starts, the fire is hot. Then we extract nearly all of the heat until the resulting exhaust is about room temperature. The exhaust does not rise. Cold plug.

He is a Small Wind installer, CPHC (PHIUS, Passive House), Landfill Manager, Hazcom 40, and Mud Buddie. In short, an overeducated mechanic that enjoys playing in the mud and preserving the planet.
is an experienced entrepreneur with a demonstrated history of working in the renewable energy industry and commercializing obscure technologies. Over a decade of combustion system engineering experience, including the engineering of diesel engines, aircraft engines, and biomass combustion systems for residential and commercial applications. Extensive experience in mechanical engineering, drafting, and design. He is currently the CEO of Liberator Rocket Heaters, which has the world's first and only rocket mass heater that is tested and certified to being compliant with UL-1482, ULC-S627, ATSM-E-1509 safety standards, and fully EPA certified.
became interested in Permaculture in his teenage years. After attending a PDC in 2016 he decided this would be a direction he would pursue for his life. Since 2019 Isaac has been pursuing opportunities and projects that allow for learning and practice in natural building, wood working, farming, and videography. Isaac often spends his other time working on sailboats.
is a turkey herding, pig wrangelin permaculture lovin handyman that people are crazy enough to give him money for, Rocket mass heater builder, and certified Garden Master. Was in the first permaculture design coarse at Wheaton Lab also has been through Geoff Lawton's online design course.
organizes mutual aid projects with neighbors in Cleveland, Ohio to meet basic needs, advance housing justice, and advocate for greater community control of decision-making. Her work as a grant writer, project manager, teacher and builder focuses on developing healthy, affordable housing and community self-reliance. Her tools include rocket mass heaters, natural building, Permaculture and other urban land regeneration practices.
is a natural builder who has taught with Cob Cottage Co. and around California for over a decade. Kirk's particular interest in Rocket Stoves and Rocket Mass Heaters is in providing a pathway to super efficient, high technology solutions; with low technology, do it yourself methods. Kirk, also known as Donkey, is the administrator of donkey32.proboards.com, a hotspot for discussion and innovation of all things Rocket Stove.
