its helpful to see the temperatures taken across the elements of the heater. demonstrates how the wood is being used more efficently compared to a traditional wood stove. rocket mass heaters are awesome, i want to have one in my house some day!
Ooh I like this video and that's a beautiful rocket mass heater..! I really, really want to build one some day. Mine will be in an outdoor structure, almost like tipi. Earlier when I have thought about it, I was planning it to have a cob bench, but now that I think about it a pebble style mass heater like this might be the way to go with our resources. Oh well, that's still far away in the future, and when I actually start the real planning, there are so many people that are happy to share their knowledge in the permies forums that it's going to be easy to polish the plans to an awesome reality.
Excellent video, Andres, Paul, & Samantha. Paul, isn't there a sign about not putting your shoes and stuff on the granite slab because they can melt or something?
This video is so well timed! I tried sharing a link to it in response to posts on Twitter with the hashtag #coldwave (OK, not to the ones about the coldwave in India - they are still above freezing but just really frickin' cold for India) but I've gotten no engagement.
What is the area being heated? Anything else going on in the house, like cooking, exercise, lighting, etc? It seems like you're getting more btu's out of the wood than is possible.
Most wood stoves send most of the wood out the roof. Here is a video about the efficiency ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-A-xK7vZd7nk.html
Great to see these kinds of videos being put out. I imagine the burn time is only like an hour or so. Means you now have way more time in your day for other tasks(infecting more brains with permaculture). Still surprises me that this stuff needs proof. Who knows maybe the more its put out and reminds people, the more people will see it. Great job! Defininetly liked the ending with the beat up truck crashing into the person.🤣
@@paulwheaton If I remember my facts correctly, it takes about 8 viewings for the average person to key on any data/image. After that, you have to work through any of the biases that might exist. I believe that a rocket mass heater would work, I just have trouble figuring out where it would fit into my life. I live in a mobile home, so a metal crackerbox with high potential for problems and generally difficult to modify substantially. I think this would be a better system for a more substantial home, or at least one that's not quite so flammable and wrought with structural defects.
It is a double wide that does NOT have an enclosed porch. We have some shades on the windows (you can see) but not proper winter curtains. So there is some, but not a lot.
I love the efficiency of this. Other than describing it as "a few sticks", would you mind re-doing and essentially the same video and WEIGH the wood you put in? I think that would be a great add for your channel. I want one or something like it.
I would like to also know the size of the total area being heated and the temperatures at the extremities. It’s naturally going to be warm right next to any woodstove. It would be more convincing to also show temps at the farthest corners of the total area in all those time frames. I like the concept but I doubt I can heat my 1600sf two story house at -20 on ‘a few sticks of wood’. Even Peter V says on the batch box website that it may not be an adequate system in really cold locations.
Since seeing this, I have watched a bunch of your other videos, and others on Rocket Mass Heaters. I knew a tiny bit before but a lot now. There are MASONRY HEATER experts that build and ship cores and do 2 fires/day of 50-60 lb of wood ea. (depends on size of house and LOTS of other factors of course) and they are very efficient, but you seem to be using far less wood than that. Please consider a do-over and weigh the wood and describe the house size and how its insulated.
I've been obsessed with MHRS for a good while. How do u all get insuarance coverage? I got the Liberty rocket stove last year bc our insurance said it needs to be ul rated. Still dont have it going bc there's a back draft. Uncle Mud has been helping me, Im so grateful for him.
This is our first winter with a rocket mass heater & I will never not have one. There are some things I will tweak this summer but the difference is night and day. I recommend anyone interested should grab Ernie and Erica's book, RMHs are game & life changers in a great way 💖💖💖
The UK government introduced rules last year that any wood burning stoves had to use kiln dried wood to prevent emissions. At the same time they're telling us the particulate emissions in a home with a wood burning stove were higher than it we were sat on the sidewalk next to stationary traffic breathing exhaust fumes. Do you have any info on particulant emissions using an RMH ?
I am looking for about your product place lace me a message. When I post this, I am looking for more information on this. Looking more on this builds thing on it .
Question: an a small rocket heater work inside a fireplace? How would it be different from regular wood in the fire place? I have seen tiny rocket heaters. Just curious about how this could work for a regular house...
Modern fireplaces are designed more for viewing the flames than for clean efficient combustion, They are rarely above 50% efficient while they are burning, creating a lot of smoke and letting even more warm air up the chimney to keep the room from filling with smoke. Overall they usually suck more warm air out of the house than they put in making them negative efficient. A rocket heater has a small insulated firebox that burns a little bit of wood almost completely, even the smoke gets burned so the heat from the clean exhaust can be captured and stored in a mass bench in the room before the much cooler exhaust is sent up the chimney. Rocket Mass Heaters can be installed in fireplaces, but they work best if their hot surfaces are in the room not tucked back in the fireplace. This Liberator install I did is one example ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-R7FLpV-OdF4.html it works a lot better since we added a mass bench beside it to capture the heat from the exhaust. These can also be hand built, but it can be challenging to get code approval.
@@UncleMud Very nice. I also checked out the stove rocket heater from Africa. I love the tile work under the rocket heater! Is it there for a purpose or just for decoration?
The tile covers the very important fireproof hearth board that protects the wood floor from radiant heat and dropped coals and sparks.@@FlyinDogRecords
First, if we measure 139, it is probably more like 160. Second, conventional wood stoves have an exit temp of 350 to 600. So I think we are doing really good. Third, we find if the temp gets too low, the draw gets too reduced.
@paulwheaton Could you possibly post a link to "any" successfully transformed fireplace? Carla Burke's story was intriguing, but it was scrapped in the end. Her fireplace is pretty much like mine, though not as beautiful. If I should post a new thread for debate? I could do that. Lemmeno
I watched this when it first came out. Last night, I was thinking, how much wood did you use. Judging by the time and comments, it seems it was just what was used to start the fire. Can you clarify?
My guess is that after the initial fire, we filled the wood feed twice. Note that the wood feed is pretty small, so we are talking about a rather tiny amount of wood.
@@fk319fk I feel like we have profound information to fill about 800 more youtube videos. At the same time, when we have put videos out in the past with profound information, they were getting just 700 views. So we are transforming the way we do videos (I hope you like it). Our goal is to get 10 minutes of content packed into a 2 minute video. And offer longer versions on patreon. The new "packed" videos will, hopefully, get 100,000 views - so we are infecting more brains. And, hopefully, patreon will get funded so we can pay for more and more content to get onto youtube. There is a LOT to share. But it is difficult to do the work of sharing if hardly anybody looks at it. There is more about this burn currently at patreon.
Hey paul wheaton thank you for this video. Hey, I just sent you an email about the DVD's I bought from you. We are getting ready to put hours together and was hoping to check out the videos once again.
For years, I've admired the concept of RMH but no way on earth could I convince my wife to have a 55 gal barrel in the house. I have a 32'x50'x10' basement which could avoid the 'appearance' issue were I to install a large RMH down there. I have 6.5 acres of pine trees which could easily provide a lot of creosote filled wood. Assuming the high temp in the riser, can I assume the creosote is not as great an issue as in other wood stoves? As my gestapo NY State gov wants to ban gas appliances, this could be an end run around her dictatorial actions.
I want one. I'm relatively handy. Are they easy enough to build for a somewhat intelligent person, just from the instruction videos that you sell? I'm not fond of traveling or group workshops. 😏
How do i find an experienced builder to install one in my house? Most ppl (including myself) wouldn't take this on without someone to work with who knows precisely how to build it! So how do I find someone?
@paulwheaton this looks like only information and not a list of builders. I'd like to find an actual builder in Western Washington. It says Walker Stoves is one but the link is broken. 🤷♀️
Amazing technology, what’s the ratio? Firebox/gasifier/steel drum/exhaust flue length/amount of mass/final exhaust pipe length? How do you determine the heating load when constructing the mass heater. The DOE maximum on my boiler is 180,000 btu per hour it’s operating twice a day for two hours and the heat in the cast iron radiator’s keeps us warm for a while. Since my heating loss calculation for my house is 130,000 btu and I have 4 apartments I would need to construct 4 rocket mass heater’s and operate each individually to get the desired effect. How do you design the system ? Do you design for the coldest day of the year with at least one window open? Do you design for heat loss calculations? Do you design for maybe it’s going to work, they can open a window if it’s too hot?
