With a conventional wood stove, it’s important to keep chimney gasses hot to not allow creosote buildup. A buildup in creosote can lead to a chimney fire.

If you can run a hot enough fire, you can burn up gasses that lead to creosote before they ever each your chimney.

Rocket stoves are are the heart of a Rocket Mass Heater. They burn very efficiently.

Much like electricity can be stored in batteries, heat energy can be stored in mass. An example of thermal mass would be a brick or cob bench.

Anecdotally, people who switch to a Rocket Mass Heater claim to use merely 10% of the wood required by a traditional wood stove.

Why cut, split, stack, and burn the wood just to send a large portion of that energy straight up the chimney?

Heat your home, not the climate.
