Rocket Mass Heaters

SpiritWood Natural Building offers to consult or build Rocket Mass Heaters (RMH). RMH are highly efficient stoves similar to Masonry heaters that burn at extremely high temperatures and have exceptionally low emission rates. These wonderful stoves burn less fuel, for less time, giving off less emissions and saving home owners hundreds of dollars each year in savings.

We offer both J-style and Batch box heaters. Materials for a batch rocket costs approximately $1,200 and the total in labor depends on the build itself. Check out some of our builds below and contact us for a quote.
