Stove chat Live with Matt starts in just twenty minutes.
Its the 19th of August ... elk hunting season starts in 3 weeks!
If the elk are bugling then its time to think about your stove!
Wouldn't a nice RMH that uses 1/2 or less of the wood that you burn now be pretty nice???
Come join us at stove chat and hear all about them!
Buy some plans from Matt and build a riserless core or just build your own!
Either way Matt answers any and all questions you may have!
Hope to see you there!
Its only 15 minutes and counting now!
Last week Matt took a small vacation away from Stove Chat to catch the last waves of summer, but he's back again this week to help us with our builds and possibly show more of his customers design examples of how people are using this safe and clean way to keep warm, heat their water or cook their dinner this winter. Look forward to seeing you there!
Hi All; After a week off, Matt is back and ready to talk!
Stove Chat Live # 22 starts in just 15 minutes!
We don't know what Matt has in store for us this week, but you can be sure its good!
Don't delay... open Matt's channel now there's only 12 minutes left!
Stove Chat 22 tip: Do you know what Analysis paralysis is? Its actually a very common disease that affects budding rocket scientists from ever getting started on their builds because they get caught up analysing everything so much that they become paralysed and therefore don't do anything to even get started.
So if you are unsure about what to do about taking that first step or find yourself wanting to have everything figured out right from the get go and getting bogged down by it, this next episode could be for you.
Matt said last week he'll be covering peoples current builds and helping them get past this common affliction.
I emailed him just this morning of a build I'm working on and am excited to hear what he has to say.
Stove Chat 23 tip: There are many questions that Matt gets repeated by many people and having to answer all the time. One of them is whether or not his designs can be reduced in size. Through the years, I've seen this question come up also for Peters batch box, J tubes, and RMH's in general, but I think Matt's answers can cover them all fairly good.
In my own words: The size it is now covers a broadly applicable function - heating, cooking, water heating potential etc. The number one limiting factor is the core.
When they start getting smaller they run into all kinds of problems and are much more finicky to operate, but if you are willing to accept a much narrower range of function, then smaller could work. Practicality below a 6" system goes way down. So the bottom line is, what are you willing to give up and how does the stove best suit your needs?
Hope to see you in the Chat today. Bring your questions so we can all learn together.
Stove Chat 24 tip: Matt encourages everyone that it doesn't take a workshop full of people to build a RMH, that it can be done alone if needed and certainly not terrifying to build. Our forum leader recently has proven this with 2 batch box conversions under his belt in the last few months.
Also, that most of the complexities of the European masonry heaters out there are not essential for a properly functioning stove - some things just being traditions that are passed down to the next builder. Everything we can do to make these things more easier and approachable will get more people to experience them. So come on out and see how easy it is to join in on the fun. Winter is fast approaching so don't put it off. There is an efficient and clean wood heater with your name on it....you just don't know it yet!
39 minutes and counting down to Stove Chat With Matt Live #25 !!!
Twenty five weeks Matt has been sharing his time with us. He answers your questions live!
Iv'e been building Rocket mass heaters for over seven years now and I learn something new each week!
The one thing I've always liked about rocket mass heaters is the broad range in which they can be modified to suit your needs. Then after a year or two if your needs change (or your like me and just like to tinker with a new idea) can be easily dismantled and made into something different. Materials like Clay/sand mortar, cob and stone are so forgiving and are often available right under your feet for free, so there should be no reason to say you can't build one yourself.
Hearing about your ideas and how to make them manifest is what Matt enjoys to talk about which not only benefits you, but also to others who may get inspired too.
So come join in the chat today and see what creations are being thought or being currently built by others around the world.
Stove Chat Live with Matt #26! Starts in less than 30 minutes.
Come listen in and hear about all the new builds starting up around the world!
Ask the builder questions if they are tuned in or Matt will try to answer for them!
Get inspired to start your own build.
Cutting Splitting and stacking wood is alright BUT with a dragon on your side you will use much less!
Stove Chat 26 tip: Being a rocket scientist means that you have to accept that your best laid out plans don't always work out as smooth as you wished them to be.
For Thomas, it was not cleaning out his system before lighting up his new dragon and now having to deal with all that moisture laden ash from the previous year. He's still working on it as we speak but making progress to get a healthy bill of health from the rocket doctor.
For me, it was getting a fail on my report card from stove master teacher Matt, saying that my firebrick splits were not stacked in a way that was considered a "building technique" and that the holes in my red clay bricks, when they get filled with mortar, might not hold up to the stresses of the heat cycling.
See what your missing by not coming out and listening to Stove Chat? A front row seat to watch the gong show of what not to do so that it will make you look like a pro when it comes time to build one yourself.
When designing a heat exchanger for your rmh, Matt feels its best to go with a bell design rather than a piped run. He explains this for the following reasons: Least material (no pipes to buy), less labour (a lot less cob to make), less heavy (for second story or weaker floors), more flexible in shape and design (no straight pipes to limit your creativity), efficient at extracting heat (internal surface area is much greater than a pipe run), lower resistance to gas flow (gas is free to roam without forced friction points) etc.
The one place where a piped system can be beneficial is in a long bench run. This would be a great place to make a hybrid system. The pipe helps to better carry the heat down to the opposite end of the bench (which otherwise may take a long time for the gasses to naturally flow down there and heat up) then return to the exhaust opening via the bell space. The pipe can also be shortened to lets say only half way down the bench to better control your preferred heating locations.
Very simple, very flexible...I like it!
Matt will be chatting with us live again today at 11am PST so bring your questions, comments and pictures. He may just showcase your stove to the world so we all can have a good laugh...I mean marvel at your creation and give some great tips on how to improve it!
For the most part, draft occurs as a result of temperature difference between the intake and the exhaust, also known as ΔT (Delta T).
The bigger the difference, the more draft and vise versa. One way to really help a sluggish draft is to install a bypass. A bypass allows you to change the conditions of your stove to overcome the conditions of the weather and environment.
Its an easy thing to grasp but is often overlooked as we rely so heavily on modern technology to take the place of natural systems and forget how simple and effective nature can be if we give it what it needs to just be itself.
Are you ready for your next fix of Stove Chat?...coming up in just a few more hours... I'll be there and hope to see you too.
Stove chat #29! Starts at 11 am pacific. @ https://www.youtube.com/user/broaudio?app=desktop Its hard to believe that Matt has been sharing with us for Twenty Nine weeks!
Every week there is something new to learn. Awesome photo's of builds from around the world!
Advice and suggestions freely given! You can email Matt ahead of time and ask your questions. Then he will give you answers live!
Access to a premier master builder Live! It can't get much better than that!
Stove Chat tip #29 You can only extract so much heat from a rmh before it will stop working properly. - Whether it be a lot of metal radiating too much heat, wet cob, water heating coils etc. if there is not enough heat getting to the chimney, draft can be weak and cause your dragon to sputter or even run backwards (not a good dragon!).
This has been a common theme this week where several rocket scientists have experienced this first hand. It is one of many contributing factors in which a rmh will not operate properly and could be something to consider if your having issues as well.
To find out more great tips like this, come join us in today's chat and work your way towards getting that degree as a rocket scientist you've always dreamed of.
Stove Chat tip #30
If you are put off building a batch box rmh because of the extra work involved, there are many ways to fabricate the parts needed without having to know how to weld or be a master craftsman to do so. For example, the secondary air delivery system to the firebox of a batch box rmh can be as complex as welding one together or as simple as friction fitted or even screwed in place to produce a satisfactory air channel. If this does not even sound simple enough for you, there soon will be a rocket scientist on permies offering his services and hardware for all your rocket stove needs..... Coming soon to an online vender near you!
Be sure to check out today's stove chat #31 for more exciting details you won't find anywhere else on the planet.
Stove chat #31 starts in just 25 minutes!
Plenty of time to get your affairs straight and sit down to listen to master builder Matt impart pearls of wisdom.
The future rocket stove store is not open yet but their secondary air tubes are available now.
Contact email@example.com if interested.
Stove Chat tip #31 - One of the biggest catch 22's to insulating under a rmh on a combustible floor is that by the time you add insulation, the pipe (or bell space), then the thermal mass, the bench becomes too high to comfortably sit on. Matt strongly recommends not compromising on insulation space to lower the bench but rather to build some sort of raised platform or step around the base of the bench instead. A very simple way of solving this problem without risking a potentially dangerous situation of the floor slowly charring over time without you even knowing.
Another episode on its way today at 11am. Hope to see you there.
Stove Chat #32 Tip: Efficiency is a lot more than just what the final exhaust temps are at the chimney. For instance, you can have really low stack temps and think your getting really high efficiencies but not be burning clean at the front end of the stove. Heat extraction and efficiency is all about the system as a whole, not just a part of it.
Stove Chat starts in about 3 hours. Bring your questions for Matt to answer live and hang out with other fellow rocketeers around the globe as they share both their pearls of wisdom and flaming crash landings as well.
Stove Chat #33!!! Starts in just 30 minutes!
No telling what Matt has in mind for today's show.
We might get to see builds from around the world or we might listen while Matt answers your questions from email or asking him live on chat!
No matter what the subject, you will learn something you did not know!
Pop on by there is plenty of room on the heated bench to sit and listen!
Coppicing is a great way to obtain fuel for a RMH. It can be a local and sustainable source of fuel, little to no splitting needed and can be harvested often with only with loppers.
If coppicing is not your thing or don't have access to this type of fuel, large branches (particularly from Douglas Fir or Tamarack) are particularily dense (which is of great fuel value) that are often discarded.
I'm going to try both these methods next year and see how it works out for me.
Today's chat may include a very special upgrade to Matt's tiny cookstove provided by your friendly neighbourhood forum leader that you may want to check out. Hope to see you there.
Stove Chat #34 starts in just 17 minutes! Stop on by and listen in as Matt shares his knowledge with all.
I sent Matt a new Dragon Tech door for his tiny cook stove. He may have gotten it installed this past week.
Pop in and see!
11 am pacific high noon mountain time
For those people who want to incorporate a water heating system to their RMH, this is the episode for you. Some very good tidbits to get you started.
....And for those that think they don't have the proper skills or time to make certain hardware for their heater, no worries, a new business has just opened up called Dragon Technology by our forum leader Thomas Rubino who like Matt, is here to help you out in designing the stove of your dreams.
Matt just installed one of Thomas's doors on his tiny cookstove in his house and just loves it.
Episode 35 starts in a few hours. If you haven't been convinced yet that a RMH is for you, then I strongly suggest you cancel all your appointments and head over to Matt's youtube channel "broaudio" and catch today's chat. I'll be there and hope to see you too.
Did you know that after the core (the place where all the combustion happens), the shape and choice of materials greatly opens up and is often only limited by your imagination?
Like many things, we have set ideas of how they look based on a set model and often think we can't change them.
Matt shows us a few examples where people have used man hole covers, old glass range cooktops, propane tanks and other objects that were never intended to be used in this manner but fit the bill just great.
A stove may look a bit odd or unattractive at first, but its amazing how a lot of it can be prettied up with cob or some kind of a skin that hides all the functioning parts and leaves you with a fully functional and decorative piece of artwork in your home, boat, trailer, yurt...etc.
Another live episode starts in just a few more hours. Come hang out and learn from rocketeers all around the world earning their rocket scientist lab coats under Master builder Matt Walker.
Stove Chat #36! starts in just a few minutes.
Come listen in and see what you can learn today.
Ask questions live from Matt or from other listeners on chat!
I learn something new every week, you can too!
But only if you stop on by and check it out!
Every show is taped so IF your working you can check it out later!
Looking to see you all there!
Still time to email in questions or just wait and ask them live!
I'll be there as Belgian Gulch. Stop on by and say hello to the crew.
Maybe pull up a chair and listen in it's only an hour or so long.
Might be its time to build that RMH you have been dreaming about!
The question came up as to why it has been said not to use metal in a RMH, yet many stove designs have a metal barrel on the top? What's up with that?
This is only true for using it as a material to make the core which is then insulated, but when placed anywhere outside of the core, it often is a great choice as a radiant heat source or as a form to shape a bench or manifold.
Come join the chat starting at 11am PST and see what questions and wisdom Matt has up his sleeve to share with us today.
Hope to see you there!
Ten minutes and counting down.
No matter where you live, surely you can find time to watch as Matt amazes us with his years of knowledge!
If you have to be at work then be sure to watch the video version later! You'll be glad you did!
So Matt's finally been able to get Starlink internet (which I wasn't there last week to experience) but apparently its a much faster connection which would mean less buffering and real time live viewing.
I'm on a satellite internet connection which has often made it choppy so I really look forward to see for myself how much of an improvement it has on the live stream.
Hope to see you there!
Thirty Five minutes and counting down until Stove chat Live!
9 Months Matt has been sharing information and photo's from builds all over the world.
