A masonry heater is a high mass device that allows wood to be burned for home heating in a unique way. It’s main distinction is the ability to store a large amount of heat. You can rapidly burn a large batch of wood without overheating the house. It has an interior construction consisting of a firebox and heat exchange channels built from refractory components. A brief history of masonry heat Many cultures liked to gather rocks around the open fire. Rocks were often piled up as a reflective back drop.

A masonry heater Energy: Radiant vs. Convection The long wave is like The short wave is a blast warm sunny spring day. of intense heat. Essential to a properly working masonry heater Dry, well seasoned firewood is critical for good combustion in any wood burning device. With proper maintenance The combustion of firewood is so complete that there is virtually no creosote residue or soot deposits present anywhere in the masonry heater. Only a small amount of fly ash may need to be vacuumed periodically Improper maintenance or operator error results in this: or even worse When things go REALLY wrong https://www.adn.com/alaska-news/anchorage/2017/02/10/home-near-downtown- engulfed-in-flames-during-morning-fire/ Via ADN.com, Anchorage, AK, February 2017 Catastrophic devastation can happen very quickly https://www.echoak.com/2017/05/destructive-fire/ Via ECHOAK.com, Eagle River, AK., May 2017 Why can’t I burn wet wood? 1. Creosote contributes to very poor air quality 2. Reduced combustion = less BTU’s 3. Waste of 4.
