This project has been one we have anticipated with much excitement, enthusiasm and desire for years now, as a big way for us to live more sustainably on our farm! My husband learned about Rocket Mass Heaters a few years back on http://www.permies.com, and since then we have been researching the topic and seeing how others are building theirs, as we wanted to build one here on our farm. A Rocket Mass Heater has many desirable benefits that we cannot wait to enjoy. Such as, using up to 1/10th the wood compared to conventional wood burning stoves, making it super efficient and sustainable. Plus less work in the long run because you can heat with just the sticks that die and fall off our trees on our land. Also most of the heat from this style of heater is retained in a cob mass and is conductive heat energy, meaning we can actually sit on the mass that holds the heat. Also the core of the heater is very rockety and cool. For more info on Rocket Mass Heaters here: http://www.richsoil.com/rocket-stove-mass-heater.jsp
Here is a series of pictures from our creative journey.
So far, we fired it up tonight, and it’s not quite rockety enough. Smoke is coming out the feed tube and the draft seems to be choking. So tomorrow we will take off the barrel, give it about another inch or so lift and seal it back up. Will keep ya’ll updated as things progress. After this fix we plan to begin cobbing in the duct to make our mass/couch. ♥
WE HAVE SUCCESS!!! Tonight’s burn went amazingly well. We took off the barrel, put in some pieces of patio blocks around an inch thick to support the base of the barrel giving it the desired lift, in hopes it would make it more rockety and burn better with out any smoke backing up into our living space. IT WORKED! It is a bit smokey getting the fire going, and getting the whole system warmed up, but after she gets going it works amazingly. We’ll take it 🙂
