Your videos are appreciated, Robert. You are giving people multiple options to partially or even completely meet their energy needs in key areas. What they do with those options are completely up to them. What the idea seems to be, if I understand what Robert is attempting, is for people to improve and refine the devices and freely share their findings/efforts so beneficial devices that work can be replicated and put to use by others. In this way, research and development can be shared by many and should result in useful, beneficial devices built from easily sourced parts that are affordable and require minimal skills for end users to assemble. Bickering and excuses suggesting things can't be done are a part of human nature and understandable, but are usually not helpful toward achieving the end goal. Well thought out contributions/suggestions and hands-on work are what is needed to move toward the end goal, IMHO. Toward that end, if ongoing funding based on results (partial funds released upon each step forward) could be set up for people doing the hands-on work to cover materials, the process would probably move forward a lot quicker. Perhaps something like crowd-funded grants to people who actually put in the time and effort to build these devices. The whole concept seems to be to reduce reliance on our current systems and corporations and literally put the power in the hands of We The People. At any rate, that's how I see it.

Next, step in heating efficiency.👇 Using indoor air to fire it and venting the exhaust, pulls COLD air from outside through cracks in walls around doors, windows and whatnot into the home adding to cold drafts. The next step in efficency is to make a fresh air intake using outside air. And one can preheat the fresh air intake by running it through a portion of the exhaust. That way you loose less heat and your house is less drafty with less cold outside air being drawn around windows doors and cracks.

All sections bolt together in about 5 minutes with standard exhaust fittings. On the inside tubing, weld on lengths of flatbar fins for increased surface area.

Flue is to control draft/air flow through your fire and exhaust gases. It would do you zero good above the roofline it need to be at the top of the combustion chamber, bottom of the flue pipe/chimney pipe.

In a sealed room, the occupants could be in competition against the stove to get oxygen. In a ventilated room, the cold air from outside will travel across the area, in my house, I choosed to canalise the air from outside directly into the burn chamber, the intake is thermaly insulated to avoid condensation.

Cracking fun what you are doing with rocket stoves and all the other heating projects! check out the rocket stove setup in Earthship homes, cobb structures etc. with the correct set up the exhaust gasses cool quickly in the outer chamber where the burn pipe IS insulated from the outer chamber and the outer chamber radiates enough heat to cool the gasses just enough, causing the exhaust to push itself through long horizontal pipes embedded in earth benches and requiring little to no traditional draft of a vertical chimney These designs have a little more detail and are great for permanent installations using the mass of the bench as a heat battery!

Yes, a manifold would work really well with this design. I also think a secondary mass(ie...sand ect.) for the exhaust to heat with a ceramic or terracotta side facing in toward the room to heat would be a nice add on. Nice build Rob! Baffle it too much though and it will start to get really noisy as in loud popping noises as it sucks air in. With this build probably not so much though. Great and interesting video Rob!

I had seen the last example Stove you showed in the video before. It's a little more complex in the fire box design as it creates a3 stage burn by allowing the pellets to begin burning on one level and as they get smaller, they fall through a grate to the second level, then again into the ash box. This is supposed to allow for continuous burning for days or months on end. Perhaps a similar feature added to your stove would be a nice feature. You might also consider a second feed box on the side for pellet feeder. This would give you multiple fuel capability.

I'm wondering if you use thin fire bricks (like in a regular heater) to glue to the outside of the box and hopefully absorb as much heat from the gas exhaust before being extracted out the flue. Would that rating maximum heat to radiate to the room?

One design I made was similar too Robs classical initial build but I welded 6 X 100 mm tube to the 100 mm upright . One on each side . Only spot weld every 100 mm along . This creates conductive passive air flow for the room . The burn chamber went up 1.5 m and back down and out . It created a lot of heat and it was open plan living . Certainly wasn't a set and forget relaxing fire though . The burn rate was every ten minute with dry hardwood but man did that thing get hot . I ended up putting it out in the shed as it was not a practical design for in the house . A bigger fire area for larger pieces would be better for that like a arm size peice .

Insulation isn’t necessary i’ve been burning a2 inch round rocket stove with pellets and it’s only steel it will reach About eight or 900° at its maximum and I’ve never had to replace anything on it I believe that’s because it’s allowed to cool down quicker with no insulationAnd with no insulation it still gets hot enough to burn 100% clean

The Vortex Stove explored in Video # 1730 is perfect for supporting flame in a confined space and greatly reducing impingement. And the 3 curved plates circling the flame is the very best example to archive this that I have seen. And combined with the second jacket as illustrated in Video 1741 provides a location for a copper water coil to be in the flue stream without being introduced to direct flame. This would work well just like the outdoor furnace so common in Canada. The water would be circulated into the home and through a water coil in existing ductwork for example. Now what I haven't seen yet is the introduction of a proper WASTE OIL burner at the base complete with an auto float system that maintains a constant level in the pot and does not use the more common fuel drip system which is subject to temperature, supply tank level, and potential clogging. Your thoughts?

Thanks to your channel I am thinking of a big rocket stove enveloped with a 2 ton'ish sand battery with a water heat exchanger plumbed into my underfloor heating. In Scotland we are using £3-£5 per day on heating only, our worst was £7.30 in 24 hours. If it wasn't for my O.A.P parents and Mum being disabled I would turn the bloody heating off. And we are not even in the depths or winter yet. All very, very frightening.

The timing of this video is great for me since I'm getting ready to build a Rocket Mass Heater for my itty-bitty mobile home. RSM gave me a thought (again): Would a car radiator in-line with the exhaust be piratical? I've three small aluminum ones I think I could place at the farther ends of the exhaust (or maybe a 20' side run to the bedroom). Optionally, I have access to the old steel radiators for higher heat tolerance. Or perhaps a closed-loop water filled piping system may be more practical?

That's awesome... great video :)

Insanely efficient, not the easiest or neatest of options, and not nearly as cheap leftover shopping bags. PERSONALLY i would pick aircrete for the following reasons: 1: Fireproof, 2: can have flame retardant(s) added into it, 3: will not rot, 4: finds gaps that even plastic can not find, 5: has some structural value, 6: can have refractory components added to it, 7: can have waterproofing ingredients added to it, and 8: helps make a home slightly more earthquake and tornado resistant because it bonds to all of the properly prepped surfaces and makes the entire structure 'unitized' as a form of crude 'composite'. The only things you need to do to ensure a good pour of aircrete before you pour is to 1, 'adhesion wash' all the areas you wish to bond it to. This can be done most easily with a low pressure spray wand with a swiveling head, inserted from the top or the bottom of any vertical wall, and from any end/side of a horizontal plane such as a floor. This adhesion material is also home made, and contains a mixture of the water soluble 'water glass' with some ultra fine cement powder in a light but self suspending slurry, and 2, follow this by plugging any holes where the aircrete can leak out of when you do to pour it. You may want to let the holes alone a few days before you put in the aircrete though, just to be sure that the preparative coating has time to harden up. This material will partially soak into any porous surface it sticks to [which means it won't stick to very well to romex or PVC, but that might end up being a good thing, as you never know when you may need to service those] and act like a primer, to ensure that the aircrete then has an ideal surface to bond firmly to. Once it hardens, it will greatly increase the total strength and rigidity of the structure. THIS guy, is like THE KING of aircrete!!! I have NEVER EVER seen ANYBODY do as much with aircrete on the face of the earth!

The horizontal part of the stove needs to be longer, because the smoke will stay in the flame longer, giving more smoke the chance to burn, causing more heat, and the riser needs to be round with the incoming fire, heat, and any smoke to enter off center which causes a swirl, so instead of everything just rising up, any remaining smoke has more time to burn, allowing for more heat.

What size stove pipe are you running for your chimney out with this unit?

Another way is to use heat exchangers on each end. Pipe the heat into the house with copper or aluminum tubing. Fire outside, radiator inside. Oil or water might work.

I'm curious how it will perform with Anthracite? Maybe some slight modifications by adding a "grid" and ash pan.

How about a simple device that runs on Browns gas? (a gas which can be easily/cheaply produced) I reckon you would come up with a great device. A heater would be great.

I've built a pellet basket for mine, worst issue is overheating and flash burning the pellets...any ideas for a efficient heat sink? Should the fins be 90°, 45° down, or 45° up?

Put a ratchet on the gear so the mass drags the gear along, but you can pull the other end of the chain to raise the mass without reversing the gear. Then connect the gear to another one driving the auger with an appropriate gear ratio and you're all set.

So Robert a question about rocket stoves , is can it be made to work in a similar way to the vevor diesel heater that you featured in one of your video's in a similar way to what you've done on this video by fitting old motorbike cylinder's onto the manifold, then boxing them in & then fitting a fan to the box to blow air across the hot cylinder's to then vent out into the room for heating??? (Ps: also can the wasted heat from the exhaust on these diesal air heaters be captured using a similar principal to what I'm talking about here? ( Just seems such a waste of good heat from the exhaust to the outside!) Loving your videos by the way! Many thanks for the good entertaining way in which you do them! From Johnny bird up in chilly North Yorkshire!🥶🥶🍻😂🤣

Used outside, I wonder if one could use an offset-fan-driven exhaust to push the exhaust, now mixed with fresh air (or just air heated by a shrouded flue) through a duct into one of the vents in the wall of one's house to heat the air under the floor, hypocaust-style, if one has an older property. It need only keep the chill away.

you certainly could do something along those lines

Does the flue have to be vertical? If it could be horizontal, many possibilities would be presented.

Does the chamber fill with creosote?

Cast the whole thing inside a block of refractory cement and you get a thermal storage heater..

I wonder if a bunch of screws or thick nails welded into the box half in half out would make much of a difference with the extra surface area?

I doubt it - not for the work involved but you could try it if you like

Could incorporating a catalytic converter somehow in the mix be beneficial Mr. Smith?🤔 One of your recent videos showing the heat retained in a catalytic converter was fascinating!🤓 Oh and just out of curiosity 😼do some people there in the UK call it a 🚙Cadillac Converter?😛

If a rocket stove is well insulated and burning at the correct temperature, there should be basically nothing left to catalyze.

I guess you could and I have never heard that

I wonder if there was a hot water jacket welded to the back of the internal flu would it create a downward draught due to temp Differance thus increasing the air flow through the appliance

I don't know - interesting question though

I really enjoy your videos, even if some of them, such as this rocket stove and its indoor adaptor, are way beyond my skillsets. I am hoping to have a go at your Homemade Heater, the one in 1702, but I've hit a snag. It's this 100% carbon felt you use for the wick, I just can't find this stuff anywhere. I did find a 98% carbon felt, but you emphasise in the video, to make sure its 100%. I even sent your shop a message, asking if any of the material you sell was what I'm looking for; none of your listings that I can see mentions anything about 100% carbon felt. Unfortunately, I received no answer to my query, maybe you overlooked it, so I'm asking here the same question, is there any material on your website that is 100% carbon felt, by another name. I do hope you'll help me with this, Jack Frost has already been peering through the windows a few nights, and this heater could help keep him from moving in as a lodger. 😂 Thanks mate.

lol - awesome

Could be even more efficient if you hooked up a duct drawing outside air into the intake ? That way, the warm inside air isn't used for combustion and isn't sucked out of the room. Just thinking ...

When I transition at the bottom of the bell and it will exit to the side, I try to have 400% of the cross sectional area of the riser/flue area. Allows for good flow.

Since they burn so hot & steel degrades, can you build a rocket heater with fire brick (like in kilns) to make it last longer? That would be an interesting comparison.

Fire brick wouldn't allow much heat to dissipate into the room, would it? What would be the point of having an indoor fire if nearly every joule of heat is exhausted out the chimney?

If you are using it as a mass heater (long-term, daily), then you would need to build out of something lasting....like cobb, firebrick, etc. If just using for camping (short term, intermittent) then metal seems fine.

Thank you ,you make it look so simple but it ain't.

oh - yes it is mate

I remember your ethos several months ago about upcyclling materials from domestic appliances etc ,why do we need draught when we have devices that can drive a dc fan with a compact hearth and the gaseous products feed into a heat exchanger made from drums appliance cabinets ,I'm sure you have materials to prevent oxidation ,and devise a simple feed mechanism, all you need is something to shred up the wood and feed it from a hopper into a crucible fed with air from underneath, just simplify a commercial pellet burner ,gas bottle will suffice for main burner, hope I got you thinking ?

it's really easy to pick up mate especially these days - those welders can be piked up for a few bucks!

Smartest thing you could do I put a heat sink, like you would find on a circuit board only made of steel, above the rocket stove and use a fan to move that heat off the heat sink into the surrounding area. Your welcome.

How do you cut a 100mm circular hole in sheet steel?

Basically, a Franklin adaptation to the rocket.

Saw a video of a really cool burner cant find out how to link the video but here is the title to search. "Gas are no longer necessary! MULTI-FUEL BURNER from pipe for heating.

I want to make a version of this with a water jacket for an outdoor hottub

I would use no insulation, I would cover the chamber in clay and stones for structure to accumulate the heat and emit the heat over a longer time.

Some non-insulating firebrick, on the front and sides of the box would store heat that would be radiated out even after the actual fire burns out.
