How To Make A Cobb Rocket Stove Water Heater

This cobb rocket stove has a secret...it makes hot water. By adding a 3/8 inch copper coil to this mud-based rocket stove, I am able to circulate water using a thermal siphon to heat a bucket of water. Part 2 of the video will be the creation of an outdoor shower. The 5 gallon bucket got pretty fast...hotter than a shower would need to be. In this video I make the stove with a mixture of sand, clay and straw.

Great project! I also really appreciated not having background music with everything. It had a good balance.

[@GreenShortzDIY]

Thanks for the feedback. I throw an audio track in when I need to. If my high-speed video goes over 1000%, the audio drops out of the render. So, I cover those spots with music. Plus, some sections just feel like they need a jam. :-) Thanks for watching.

@@GreenShortzDIY I do agree with Worthless Professor on this, I'd rather hear ambient sounds than a soundtrack. I realize many(not you) think they are making hollywood blockbusters rather than sharing the knowledge they have gained over a lifetime of experience. Which often comes with many failures and some great successes. Rather than the music some feel compelled to add I personally would rather hear the"oh sh** i screwed that up and i need to redo all this part" I'm a hands on guy who learns from others mistakes as well, at least when they share them. Not sure why people feel compelled to remove the not quite perfect projects. I've never started a youtube channel even though I've been making projects since i was a youngster, and that would be about 50 years ago (smiling face inserted here) keep up your great work, i enjoy it greatly. thanks again, halfnuts.

[@henrymestdagh6692]

You should stretch out the coil slightly and mount it inside a wire tube so the clay is not in contact with the copper tube. If there’s a slight space between the coils it should be more effective. You can even incorporate it in the side walls of the fire pit as well the lower it is the better. You should make a damper to slow down the burn. It burns too fast so you use more fuel. That would also be good for a home made hot tub in the yard. In summer I do all my cooking on one make of recycled bricks.

[@GreenShortzDIY]

Thanks for the damper tip. I need to learn about methods in that a little more, but I understand the concept. I do another coil in a bigger rocket stove, that is open inside the riser. Works better. I’m impressed that you do all your cooking on an rocket stove! Awesome!

[@edwilderness]

Another possibility is to wrap the copper tubing loosely around a short piece of PVC pipe of the desired diameter for the coil like 6 inch perhaps. This should keep it from kinking at all, although I've never tried it.

[@ghz24]

A damper is contrary to the operation of a rocket stove.

[@zachariahpoltergeist4516]

Sped-up construction noises is my new favorite sound!

[@siuolsretlaw8166]

To prevent kinks in your copper pipe you could try bending it around a piece of schedule 40 pvc or other pipe in the size that you want the coil to be. The trick is to keep the copper pipe close to the pipe used for the shaping and bend it a little at a time. It makes a perfect uniform coil without kinks if done right.

[@seamorebutts1594]

You can also fill the soft copper with water, then freeze it. To prevent kinkage.

Could always claim a technicality. The water heater gets hot while in operation, hence, it's a hot water heater. Either way I'm like you Aaron. I call it a water heater no matter what the water temperature is before it runs through the heater.

Or use a steel ‘spring’ that fits over the copper pipe. We used to sell one designed for this purpose at a plumbing supply I worked at. It’s coils are too tight to be a spring but it creates a bendable but circular pressure evenly over the copper. Quicker and easier than filling a length of copper. Move it along the pipe as you make each bend

If you built a hot water heater you would need a supply of hot water to feed your water heater to then get HOTTER water and that wouldn't make sense and it would be redundant 😁. You understand that and very few others can grasp that idea. Not sure what that says about the mental capacity of the rest of the world 😁.

That was cool. Always super satisfying managing to build one of those devices that heat water with only super durable stuff. Now what I want to know is how this model compares in core temperature, gas emissions, and volume of BTUs transferred to water, to a model made with the same cob and the same heating chamber core surface area, but which has the coil in the place where you would put the barrel on this rocket stove : on the way out of the hot fumes, but not in the heat riser itself. Because in the rocket stoves DVD they say that the second is better. Hey I'm building one right now!! Maybe out of stainless steel if the shop say they can weld it for me at a reasonable price. It's just to hold the ceramic boards in place, it's not the actual rocket stove.

[@rhiantaylor3446]

Thank you for the video, i'm facinated by rocket and similar wood-burning stoves. I am particularly attracted to the heat efficiency and low-pollution achievable which I understand comes from having a very high temperature extended chimney above the fire to complete the burn. Having a pipe for water heating is attractive but being so close to the inside of the chimney, I think this must negate the high temp chimney objective. I presume this why we often see a cover over the chimney, forcing the exhaust back down and exhausting at the base. The area between the chimney and the cover is the area where heat could be harvested with the coil to heat water, without risking the "hot chimney" principle. Any thoughts - have you tried this sort of design ?

[@GreenShortzDIY]

Rhian Taylor Hi Rhian. I think what you are talking about is called a rocket mass heater. It’s related to a rocket stove, but usually has a taller chimney and a barrel or some over the top to provide complete combustion while forcing the warm exhaust through a “mass” to absorb the heat and radiate into a living space. The complete combustion relies partly on a very hot riser. It’s sort of the nozzle of the rocket. I do want to eventually make one of these, but I’m still in the learning phase. Paul Wheaton is a guru on the subject. You might enjoy some of his videos. Thanks for watching.

[@monicareid8858]

Really neat design! This could be incorporated with a shower house, a hot tub, an outdoor cookstove, or add to a spa-like environment Once this is finalized, I’d use copper pipes or pecs designed for heat for the hose. Also, wouldn’t it be better for the heated water to got the bottom of the bucket (instead to the top) and the cold water to come from the top? As hot water enters the bottom of the bucket, the heat would rise, causing a convection current so the entire water mass increased gently, instead of downward in layers. The cold water, being heavier, would lend to cycling faster from the top, as well. Once the cob dries and bakes, this will become much tighter and more efficient The way you have it now lends to maintaining temperature layering and would be harder to draw from with a spigot, as the first water you draw will be the coldest. Nice prototype experiment! Excellent explanation I like your long-fiber use of cob!

Great project. The only thing you needed to do was change up the hosing.

We did this in alternative energy in college with a solar panel.

If you can do anything with fired clay (not sure if you've got a kiln anywhere your setup), it might be neat to try making interlocking sleeved cylinders. Shouldn't be too different than making pottery around some forms. Then after firing those, you could stack those sleeves to be used as a chimney liner for something like this. Perhaps adding one or two feet to the height, since those would help support the surrounding clay/cob from deforming too much.

[@GreenShortzDIY]
