by Erica and Ernie Wisner is a technical manual for constructing ultra-efficient earthen masonry heating systems. These systems can heat a home using 70–90% less wood than a traditional woodstove by capturing exhaust heat in a thermal mass, such as a cob bench, which radiates warmth for 12–24 hours after the fire is out.

The guide emphasizes the heater as an integrated system rather than just a stove. Its performance relies on a "rocket" combustion core that achieves complete, smoke-free burning through: by Erica and Ernie Wisner is a technical
