Home Heat – An Archive of Stories and Experiences About People Building For Fire to Heat Home & Family

The stories are gathering fast so a new archive has been created! The saying “Only mass can hold energy” has been rattling around the press for some months now and this is the result. A collection of stories by people who are experimenting with different techniques of building for fire in order to burn cleanly and retain the most heat possible within their homes. An activity where art and science come together – where the intuition of sculpture and the discipline of measurement are kindred spirits.

Jon and Flip Anderson have been working with stoves and ovens for some years now (HPP regulars may remember their rocket powered oven design.) Last February, they helped teach at the Winter Stove Workshop put on by Aprovecho and InStove. … Continue reading

Mass Heater for a Greenhouse Using a Wood Stove

greenhouse-heater

Kiko Denzer and I were hired to build a heater in a greenhouse for some very avid gardeners. They had experimented with using a wood stove but there simply wasn’t enough heat retained for the stove to heat the greenhouse from one day to the next throughout the winter. Our task was to incorporate the old wood stove, mostly taking advantage of the glass door and firebox it offered, and plug it into a system with channels and enough mass to absorb sufficient warmth to heat the greenhouse with one firing a day. This article chronicles that build and the results. Continue reading

Testing the Limits – Adobe Heaters in Argentina

Increase wood-stove efficiency with bricks and mud: Construction Details & Videos

about 300 pounds of masonry moderates a small space

Increase woodstove efficiency with bricks and mud This is a pretty simple do-it-yourself option for anyone interested in increasing the efficiency of an old (or new!) woodstove. That said, a heater in the home poses serious risks — greater than … Continue reading

earthen masonry heater hat for wood-fired stove
This time of year I don’t usually get too muddy, but I brought some mud into my office last month so I could have a better and more efficient source of heat — finally! This little “heater hat” effectively turned my little iron box stove into a mini-masonry heater — with an oven! (note the wooden door on the right, just above the iron stove door). The wood that used to over-heat me, briefly, in the morning, now keeps me comfortably warm all day, and into the next morning (depending on how long I fire it and how cold it is). And, unlike most iron stoves, it doesn’t generate that fierce, drying attack-heat that people try to moderate, either by burning wet wood, or by damping down their fire so it heats minimally and smokes prodigiously.

The stove was an old cast-off that now provides clean heat with minimal smoke. The surface temperatures of the heater portion are much lower than hot iron and (except for the tile, which gets hotter), very huggable. In addition, I lined the firebox with brick, which keeps the metal surfaces cooler and safer, but increases internal combustion temperatures for a cleaner burn. Continue reading

waterglass for binding earthen surfaces & pigment

“Waterglass” for protection & paint Waterglass has become my preferred binder in places where it’s needed. The chemical name is sodium or potassium silicate. It’s an inert mineral compound similar to window glass, but under heat and pressure, it’s soluble … Continue reading
