What is a rocket mass heater?

A highly efficient wood-burning system with an insulated combustion chamber and large thermal mass that stores heat and releases it for 12-24 hours after the fire dies.

How much wood does a rocket mass heater use?

Rocket mass heaters use 80-90% less wood than conventional wood stoves for equivalent heat output due to complete combustion and thermal mass storage.
