I wonder if you had a double exhaust pipe, one for a bunch and the other for for the vertical flue if it would prevent melting and regulate room temperature.
Thank you for this simple explanation about how rocket [fill-in-the-blank]s work. I've been trying to understand what I can do with them and what I should do with my situation but I'm overwhelmed by all the information and styles and designs and just need to start at the beginning, with the simplest basics. So thanks for not making my head explode. I feel like I understand it a little bit better now.
You mention in another video the coals clogging the burn tunnel. I think the charcoal itself would get you hotter temperatures, faster. I dont know of a rocket built to burn charcoal, but if you could combine the power of charcoal with the draft inducing geometry of a rocket stove, that would be amazing.
I am interested in having a rocket mass heater for the tiny house that I am building, but my tiny house needs to be mobile and I need to be aware of weight restrictions for my trailer frame. What would be the best form of heater that I could build, with the most minimal amount of weight, so that I could still benefit from having a mass heater, but not have to worry about 1000s of pounds of weight?
The Liberator is a low BTU (about 30k) heater that is UL listed and EPA approved for use in the United States. I like that a lot. The non-electric pellet feeder is also pretty great. The Gamera is a superior heater that come in three sizes up to about 55k BTU but it is not yet legal in the US. I'm working on that.
Everyone underestimates the importance of the horizontal portion of the J-tube. Just out of curiosity, try increasing the length and test your results. I've found a 1/3 to 1/4 ratio (Horizontal / Vertical) is optimal
Kirk says it is all by feel, no ratios. He mixed clay slip with ash until a sticky dough was getting less sticky, then mixed in crushed brick or unglazed pottery grog until it felt like cob, then added water to get it moist and sticky enough to mix in powdered cow poo until he had something solid he could carve into the shapes he wanted.
That is the outside air feed and blast gate I add to my installs to allow me to control how much air goes through, especially closing air feed down completely when I'm getting ready to go to bed o the chimney doesn't suck cold air through the mass. Thank you for watching.
You mentioned that you improved the sizing. What sizes did you use. I want to make one of these for my Sukkot booth for the Fest of tabernacles and run an oven in the exhaust. It will be in a tent. I have also wondered what would happen if you lined the 55 gallon drum with Fire brick. If it was put inside a 85 gallon drum you could pour concrete into the gap for thermal mass. Or use pee gravel to fill the gap.
Thank you for watching. I would tamp dryish clay between the drums for mass so you can remove the mass later for transport. Concrete could crumble under the heat. Firebrick lining a 55 gallon drum is better but a lot more expensive for a temporary heater.
This one heats the whole building (a 1100 square foot house trailer). A house that is bigger or with more closed off spaces will need multiple heaters. Thanks for watching.
How much space will that heat? at this point do they metal rather than glass top available? my cabin is so tiny, I wanted to build a RMH but can't risk carbon monoxide or fire. I need to do something this spring. I really want a pellet feed, wondering if a hopper could be put on it?
This one comes with both glass and metal top pieces. It keeps up with heating my 1200 square foot trailer house in Cleveland Ohio down to about zero (F). Install it with a mass bench and it will work well. Stay tuned for some more videos next month. I'm testing the Gamera 7 with a pellet feeder starting next week.
Isn't is though..... I wish we had more time to show you around. Busy busy with the build though.Your very welcome. Anytime. Next time bring the Fam. :-) @@UncleMud
Hi, thanks for the video, I'm wondering are you going out of the stove through the barrels, is there a stove pipe running through the barrels then outside through the upright chimney pipe? I'm off grid in Northern Maine, small 500 sq foot cabin, thinking seriously about this stove, my propane non vented wall furnace is lousy, need to either get vented furnace or switch to a stove like this... thank you.
Thank you for watching. There is a 6" stove pipe running through the barrels which are filled with cob that stores and slowly releases the heat from the exhaust before going outside through the upright chimney pipe. With the rocket heater it does a great job heating my 1200 square foot trailer home in Cleveland using very little wood.
@@UncleMud I have a 72volt Bad Boy with bad batteries.Ive used Crown in the past on my other golf cart,I gotta just decide on whether to go lithium or lead acid again.
The clearance to the ceiling is about a foot. There is a heat shield on top but you are right to be concerned. I prefer to keep a good 30 inches between the top of my heaters and the ceiling. Even with a heat shield I like to have more pace than this. Thanks for watching.
The air got up to around 160 (f) very quickly, less than 10 minutes due to the heater's large radiant surface. The benche and walls take a good deal linger to get that hot.
