Smoke from fireplaces traditionally would be injected into the atmosphere, which provides micro particles for moisture to create new weather patterns. Think of during a field battle where there might be a good amount of smoke that's expanding upward, and during that battle it rains.

The stove’s efficiency is decreased by using cold air. The occupied space needs fresh air for you to breathe, so it’s actually maybe counterintuitive to some people but using the older stale warm room air for combustion is better in every way.

thanks John!

Scandinavian people's and Russians have been doing this for a while now but the design is a little different than this one . Instead of cob and pipes to heat the mass they use channels through lots of bricks and a massive chimney. Both are considered mass heaters but this one is a little different and more efficient for sure,plus can be made quickly . I've made a few prototypes using the rocket design and also gasifiers . Both have their plus side .The good thing about gassification is you can use the left over mass which is essentially almost inert charcoal to be used for other things such as water purification or it can be ground up and put into compost or to rejuvenate soils or used for BBQ coals . By accident I made something that's a combination of both and the ash content was almost nothing but fine powder .I was absolutely amazed at how little there was left . Essentially what I did was put metal screening in place that was meant to be exposed to high temps and put it where the hottest point would be . It acted as a catalytic screen which burned off anything else the primary heat source didn't which further reduced the mass left over . It acted much the same as an incinerator .I hadn't set out to do this . I was playing around with the idea of getting more heat or utilizing the heat better and this happened . With a gasifier the volatile organic compounds are used to provide fuel for the flames and only the mass is left over because the fuel is drawn out of the mass. With this design the flame is at the bottom and top with the mass in between. I start by burning the bottom using a torch but also have a container within another one and have holes drilled at the bottom and top of the cylinder within the first one . As the fire is trying to burn up air is drawn in from the top but then the VOC's are venting out the sides and trying to rise up within the second cylinder which is then lit and looks very similar to a propane gas flame which is the secondary burn . Once most the VOC's burn off or die down the mass continues burning at the bottom like how a rocket stove works but with a second burn and then the mass is reduced to almost nothing .Its hard to explain but all I know is that it works and the end result was a fine powder similar to baby powder . I'm sure this has already been invented and that I haven't discovered anything new but it was fun playing with the design and seeing how I could use up all the potential heat and reduce the mass to almost nothing. The key issue being it has to have a steady constant air supply and must be put inside another container . I put this design in a small free standing baby bear wood stove I have and it got the steel relatively hot . I lined the inside with bricks and put more bricks on top of the flat surface on the stove which got fairly warm and lasted awhile . The pipe went directly from the stove to the outside of the building . I also had a flap inline to equalize temps before opening it up fully . Initial temps were fairly warm but the emissions after start up were almost nill with mainly a very small amount water vapor and slightly warm air coming out of the chimney . The twin cylinder was glowing red hot at the bottom which was kinda cool to see . Essentially I think what I did was use almost all the potential energy and matter that was available which really surprised me that it did that . It was a little tricky to get going but if I refine it more,it might be a good reliable heat source . In the meantime I'll stick to a rocket stove design and perhaps refine that idea a little bit . Heating up a 80X40 foot shop with 10 foot ceilings and a concrete slab using propane heat gets expensive especially at over $2 a gallon . I'm going through 4 gallons of LP in less than a week . So it's definitely time for utilizing what's all around me ..lots of dead fall wood everywhere . I see my neighbors using piles of wood and it kills me that there's such waste .Also they're using alder which stinks but it's cheap and easy to get. Not to mention my son has asthma and every morning and evening there's lots of wood smoke filling the air from all the wood being burnt and especially on days when we have no real wind movement . Yes fire places are cool to watch and very relaxing but it is possible to have both as this video demonstrates . I really hope that rocket stoves catch on everywhere so we can reduce air pollution and use less wood . If all the potential energy is used not only can you heat your home but also heat water or do passive floor heating , cooking, or turn that heat into direct energy again for power usage . There's energy potential literally all around us but we don't use it properly or know how to tap into correctly . With the current geopolitical situation happening with oil being center stage in current and future conflicts it's extremely important now more than ever to learn to reduce our dependency for oil and be more self reliant . There's great potential for energy production using incinerator technologies that use garbage as fuel . There's an energy plant on the east coast that uses garbage as an energy source for all their operations from the machines that sort through the garbage to pick out precious metals ,to the conveyor belt machines etc and all their electricity needs . Their emissions are mainly water vapor which can be reclaimed and used for other things, and very little co2 . Considering the fact that we have a huge pollution problem all over the world we need to get busy making these types of innovative ideas a reality to change our world and make our children's future a better place . And so ends my coffee fueled rant !! 😰 😸

If I may, I'm just going to start throwing this out there... Years ago, when my son was a young boy, we loved camping and discussed ideas of all things survival. I spoke about an unknown idea I had of a human waste pit, on each defecation adding a sprinkle of fire ash to deodorise, which would also balance acidic urine. I wondered if, once the small pit is full, straw or hey may be optionally mixed in, top the pit with turf for a time to partially compost the matter, then dig up and shape into blocks which are air dried and used for fire blocks as fuel, and very possibly make great fertiliser for agriculture also! I've always wondered why society doesn't seem to know what to do with it's excrement, other than throw wash it into the water ways??!

@nomms

Composting toilets are common amongst off gridders and folks that are environmentally friendly. You poop on a hole and throw a few cups of sawdust in behind ya to keep the odor down and make good compost. After a few years you move your outhouse and you have a huge patch of super fertile soil. Gotta compost the waste or it'll be environmentally hazardous. You need dry organics to balance it out, leaves, sawdust, paper, etc. A bit of ash may work, but I'd be a little hesitent as ash is pretty alkaline, would likely end up with soil that's unusable after a few years if you used too much.

Have you thought of adding ceiling fans in your shop to bring the warm air back down to mix in with the cold? It would interesting to see what difference there is in the temperature readings near the floor and the ceiling when your mass heater is fully fired. Maybe you can do a video on that sometime.

@abcacres6413

7 жыл бұрын

Good question. As I understand it, and as was previously stated earlier in the thread by another viewer, who quite honestly seems to be more knowledgable than me on the subject of RMHs..."Darrell Jacob JR 1 week ago The heat riser of a RMH (inside the drum) is basically a controlled chimney fire every time you run the furnace. It gets to 1500*-2000*F and burns all the smoke though. So there's no smoke left to form creosote in the exhaust ducting. With a RMH, the pipe going out the roof is not a chimney, just an exhaust riser to get rid of the exhaust gases (CO2 and water vapor). So you can never have a 'chimney fire'. The chimney on a 'normal', old-school woodburner gets really hot...the hot smoke and exhaust gases rise, drawing fresh air (necessary for combustion) into the stove. When you damp it down in an effort to make the inefficient stove heat the house all night, you make alot of smoke. The reduced chimney temps allow creosote to form from the tars in the smoke. Unless you clean the chimney regularly, after the creosote builds up awhile, firing the woodburner will light the flammable creosote, which will burn so hot it melts the metal stovepipe and probably set the house on fire. The only way to produce creosote in a RMH is to put a log in before you go to bed, then restrict the intake air so the log smolders all night. (Because you are too lazy to split up a handful of pencil-sized kindling to light it the next morning, and because you've seen granddaddy do it to His wood stove all your life, so it must be OK). This will produce a ton of sticky Class 3 creosote in the mass ducting and exhaust riser. If it ever lights off...chimney fire. A RMH runs full-speed until it is out of wood. The furnace's only job is to heat up the mass, which will in turn heat the house all night. When the last ember goes out, cap the feed so it doesn't suck cool air in all night and cool off the mass. Running it this way, you will Never produce dangerous creosote. After a whole season's heating, your exhaust ducting should look like you put it in yesterday, because there is hardly ever any smoke traveling through it. The only smoke you May notice is when you first fire it up, and the core is too cool to fully combust all the smoke. It will heat up to operating temps in 5-10 minutes though." Also, in speaking with some people who have worked with RMHs for over a decade, they have never had any build-up in their exhaust pipes. We cannot personally state this yet, as we have only had this one going for a year thus far. Thanks for watching!

Hello sir I have a question if you dont mind. THE SET UP..As far as I know BTU requirements can be found by taking area of walls and ceilings divided by the R value of each as applicable and then multiplied by the Delta "T" or temp difference of your worst day = BTU needs. Now that being said a small average modest 1000 to 1200 square foot house would needs about 50,000 BTU's Now with that said hardwoods at less than 10% Moisture only have between 8k to 8.5k BTU max available per pound. and that would mean in the modest house you would need to burn a little over 6 pounds of dry hard wood burned at 100% efficiency to deliver the needed 50k BTU's... heavy woods have more BTU due to density than lighter ones less dense. NOW ....IF... all that is true and modern wood stoves that are put in a calorie room and actually messured with out catalytics can approach 80%... THE QUESTION... How is it mathamaticly possible to use 1/4 to 1/10th of the wood ? it would demand a 400% to 1000% more efficient burn in the rocket stove than in thewood stove and the FACT is , it is only 20% at max possibly more efficient.. THAT sire is my question.. can you please explain that to me... I will not go into why sticks and paper thing, yet..

@abcacres6413

7 жыл бұрын

Van, don't know why, but your comment was in the spam file of comments. The one big difference between the new high efficiency wood stoves and a well-functioning RMH is the large amount of thermal mass. The fire can be extremely efficient in the stove, but the fact remains that much of the heat goes up and out flue pipe. The RMH's superiority in efficiency comes from its ability to catch and store the heat energy in the substantial thermal mass of the bench, daybed, or whatever other iteration of mass one wishes to employ for their unique context of space and utility, as long as it fits within the design constraints for proper and effective operation of the RMH. It is not in the burn chamber itself, but rather what happens to the exhausted air after, that gives the RMH an advantage in reduced fuel consumption. Thanks for joining the conversation.

It would be interesting to see if someone has done basic ductwork drawing air from near the barrel to a bedroom.

Oops... wrong subject. You would either need a stack effect, so the duct work could eminate from a RMH on the ground floor and bedroom upstairs, or you could use a simply 12-volt fan in the bedroom to draw the heat on same level plane.?.

Regarding issue of burn chamber at 6:35, most modern "normal" wood stoves also has extra burn systems, and so should also have no smoke. Mine doesn't have any visible smoke, for example. So that is not really relevant or proof of much. Just saying.

Are other shapes possible for the smoke chamber; Or does a cylinder work best?

Helleri, Our experience is strictly with a cylindrical burn chamber. I assume other shapes, squares and rectangles, could be used, but one would have to be prepared to question how this effects performance and maintenance concerns. For instance... corners in the chamber could provide opportunity for fluctuation in burn temperature or opportunity for greater maintenance needs with corner upkeep. This I theorize on, and would look for you to seek out further know-how before jumping in and designing & constructing your own. Good Luck!

Well a sphere wastes the most internal space (for containing a vapor or gas), but is the strongest structurally. A cuboid waists the least, but is structurally the weakest. A cylinder is a fine compromise between the two. It's probably the single best shape (functionally) for what you're doing. My concern is merely aesthetic based. Which is subjective anyway.

Took me two years to get the approval of the EPA in CA to install a masonary heather because it was not UL listed or tested. How did you get this approved with your county? Can you post any perperwork to we can all get the ability to create as wonderful

Thanks for the note. It turns out all municipalities have varying ordinances for the permits, if any, associated with wood burning stoves, and any said paperwork would be unique to that specific city/town. The biggest benefit on our end is that our RMH was designed and installed in a workshop... not a residential home. I understand that various designers / installers are starting to navigate the legal waters for UL listed approved heaters for residential use, but we have no direct experience with any such governing body. Congrats on your persistence and success. All the best!

Thanks for the very quick response. After I went through all the phone calls and letter I posted my EPA acceptance/approval letter on the North American masonry associations website hoping to help the next person that wants to try to build a heat. I ran into the same issue with a wood burning pizza oven! Thanks once again, great job

How often do you have to replace the barrel? They would not last long at those temps.

According to the authors of, "Rocket Mass Heaters," they replaced their barrel after 12 years as part of routine maintenance, but saw no physical signs of degradation on the barrel at that time. I cannot speak from direct personal experience, however, as our RMH has been in operation for just over a year. Thanks for watching!

I notice all the relatively clean wood behind you.....What if I put a piece of that "dirty" pine wood straight into the burner, with bark and perhaps a little bitty moss and a little bit of natural dampness? Would I expect a lot of smoke?

@abcacres6413

Chris, we do use mostly scrap wood from construction projects, you could definitely use "dirty" pine many people use windfall branches, as with any fire based heater seasoning the wood is preferred, as wet or mossy wood will create more smoke which will build up in your ducting faster...

will the pipes clog up over time?

Hey quick question what is your riser build ??

It is a heat-resistant ceramic composite board with a durablanket wrapped around the outside.

This is similar in design to masonry heaters they've been building in Russia for centuries.

Yes, masonry heaters have been around for a long time in various forms, and do a great job of supplying heat. Thanks for watching!

I stacked up four barrels in my shop and piped into the bottom one on the floor. I cut an 8 inch hole between barrels which created a baffle. I took the upper pipe out of the side to prevent water from dripping down into the barrels. The paper labels on the top barrel never browned. It only took a couple of cardboard boxes to take the chill off in the morning.

great job and presentation!

That is super awesome...now to find info in your videos about the bench!

Love this unit and good quality video. Thanks bud. Well done great job !

That's fabulous. I'm excited to utilize this concept.

Thank YOU ABC Acres! The best rocket mass heater and video I've seen so far, so much explained! I'm sure these may also incorporate water heaters also, for maximum efficiency! :-)

Nice job! If "tuned" correctly the burn efficiency is so high that cleaning is not necessary, yours looks great! Aesthetic screen can be added around the barrel to dress it up too if it is in living spaces.

Thanks Jim! It is simple and quick to clean, with us only having to remove the clean-out caps and clear a small amount of ash about once a year.

Liked, subscribed and shared on FB. This is the way people should be going, taking small steps to improve the world rather than having Govt riding rough shod over peoples way of life, with punitive regulations and banning fires altogether.

Thanks for subscribing and sharing! Clean fire heat technologies like this, and others, paired with regenerative fuelwood agroforestry, is a much more viable option for many in the cool-to- cold temperate environments, so let's keep keeping on!
