How to Build a Rocket Stove with a Built-In Water Heater!!

Nice, another adchannel

A great tip for keeping the copper pipe from kinking is to use regular fine table salt. It can be hard to remove the sand as it compacts. With salt you can flush it out, since it’s water soluble, just connect your garden hose, and turn it up, just a little bit, and kick back and enjoy a beer, while the water works for you 👍🏽

As the water heats up it will naturally move up in the coil. It might be enough to circulate the water without the need for the pump.

Awesome project! Only on suggestion....Connect the the botom conector instead of the top one as inlet of cold water. Will be less likely to have any air trapped and the cooper will be safely coolled by liquid.

Typically you enter cold water at the bottom to not fight natural convection. Cool build. I am starting a build video for a large stainless rocket stove with integrated water jacket. Also I suggest pushing MIG. You will have better results. Cheers

Always heat the copper pipe first with an open flame to soften it . Makes it easier the form around the pipe.

Love the removable heat exchange, that solves a lot of problems.

This is an absolutely awesome idea! An hour is a long time to have to run your pump. You know, if you put a fitting down about 6 inches from the bottom of your Jerry Can and reverse your flow of water, you don't need to use the pump. Cold water from the bottom of the van goes into the lower fitting of the exchanger. As the water heats it rises and goes out the top of the exchanger to the top of the can. The water will flow naturally. The biggest problem with heating water this way is you have to have a way to introduce cold water into the hot, in the shower line to prevent getting scalded. Also need to make sure you have a steam pop off valve on the can. As for your quick connects use an E3F3-B and a E3F3-B pressure washer coupler and nipple set.

I love seeing how DIY projects can solve problems when the SHTF happens. 🤔me thinks you deserve A++.

Love the rocket stove with the adaptation of the water / heat exchanger. Awesome build. Will cone in handy in many ways.

Awesome! I had a very similar idea for a harvested heat water heater living off grid about a decade ago, SO damn satisfying to see the same general idea actually built.

I’ve been waiting for this video since I saw the short. I really enjoy my electronic pump shower can. I commented there how I used the concept but modified to my needs. I thought I might build something similar like a box with the copper coil and handle that I can drop into a fire pit or place on the large camp stove. A little more portable since space is a premium! Heat exchanger box. I will probably add an insulated bag over my can to speed up the heating increase the retention of heat developed. Thanks for all the time you put in to share your ideas and finished product.

Fantastic job Patrick... Thanks for taking us along ! Liked/Subscribed a long time ago ! FJB too !

That's fantastic! Now all ya need to do is scale it up with a bigger stove, tubing and cheap or free water heater with a blown regulator or something to make enough water for a nice, long shower! Or maybe for a hillbilly hot tub!

I'm not sure i would change anything. that's another awesome idea i will have to try in the future!

With a little bit of tinkering for personal customization, you got the perfect off grid prepper device. Great video.

I'm 65 and my dad told me about using sand to bend copper when I was a young boy in the 1960s

My only suggestion comes at the end with the cross brace for cooking pans. Since your longest can is 10" you should use the same simple cross technique on top but having the longer bars reaching further out will allow for a more stable cook top for your pans. Very cool portable unit!

Excellent work dude! I use a circular saw with the Diablo blade you mentioned when working with big sheets of 6061 aluminum works great 👨‍🏭

The basic concept sounds like something I would otherwise like try a build of in a few years, after an operation-use review. ...I will hold off on watching. It's awesome to know that true efficiency (societally) is starting occur.
