"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.
The total length is about 20 pages (updates may be substituted at the authors' discretion).
Ernie and Erica private clients generally receive a complimentary copy of this manual during a paid consultation or site assessment."
