Here's some more about this manual:
Rocket Mass Heater Manual
"Rocket Mass Heaters
are site-built, often owner-built, masonry heaters. Each project
has unique elements, like the height of the chimney or the available floor space, that may affect the design.
Most rocket mass heaters share common features, like the shape of the firebox, and the general methods for operation and maintenance.
This manual includes sample drawings, fill-in-the-blank areas for site-specific details, operation and maintenance logs, and standard instructions for how to light, clean, and maintain the heater. There is also a troubleshooting section that addresses problems that may come up due to design, maintenance, or operational oversights.
If you don't like emails (we get that, though we're bummed!), you can buy it right HERE!
