Off Grid Water Heater - Hot Water with DIY Firestove

NOTE: do not build this without a preassure valve! If preassure builds up this can be super dangerous! Get a valve!

Nice! but please, add a safety relief valve at the end of the copper tubbing. I don't believe the pressure could make a pipe explode, but it could make the unions start sprinkling hot water.

[@laurakampf]

Yes, you are right. I am going to do that ASAP! ❤️

[@DIYPD]

I was ready to write the same. Other than that...once again Laura awesome project!!! 😀

[@jamesinc87]

It's not necessary here as the hot water isn't isolated from mains. A normal hot water tank has a valve to prevent water expanding back into the mains supply, but this setup doesn't have that, so pressure will always equalise with mains

[@maxximumb]

@@jamesinc87 The release valve is more to let the pressure out if the water is left to boil in the copper radiator.

[@jamesinc87]

@@maxximumb I understand, but think about it - without a check valve, that pressure won't build. The water will expand and flow backwards into the mains water supply. It might be a good idea if Laura adds a check valve to ensure the hot water never flows backwards into the mains *and* adds a relief valve. It might also be a good idea if she expects the pipes to ever freeze (I'm Australian so that's not really a problem I've ever had to think about)

Welding on the hinge and then cutting the door was brilliant. Keeping that in my back pocket.

That was brilliant! Was thinking a mixing valve would solve the temperature problem. A prv would also be a good idea as an added level of safety. Loved the video. You're very clever. I clicked the subscribe button as I can't wait to see what other clever projects you come up with next!

[@davy1458]

Hinge welded on before cutting the door= bright....not putting a handle and latch on said door= not so much!.....hopefully she installed one at a later point...along with a pressure relief valve on the water system......all in all a good design....the only thing I would have done differently was he decision to cut the top off for loading fire wood in through the top.....thats going to leak smoke and heat which reduces its efficiency and leaks smoke! Granted it looks to be an outdoor water heater wood stove.....me personally I'd have made it a water heater/hom or shop heater in one! I might cut the top off and weld a flat top cover with some stiffening ribs or gussets on the bottom of the flat top lid so that it doesn't warp excessively or make buckling noises and so I could cook off the top of it in a cooking pan..then I would surround the top with band of steel to provide a confinement ring for setting the original concave top back on the new flat top that I welded on in its place....id also put an access door in the side of the concave top so that when I wasn't using the flat top surface for cooking, I could place the concave top back on top of the new flat top and load small pieces wood into it to make my own grill charcoal....why would I do all this.....because I just love to over engineer stuff that's why! I'd probably even weld an e-vac pipe 180 degrees from the exhaust intake pipe and weld it in at an angle with a butter fly valve in it so that I could see if it was possible to draw exhaust smoke out more efficiently and use the butter fly valve to try and finely adjust the scavenging/ draw effect to maximize exhaust flow and the intensity of how hot the fire burns.....might work.....might not.....may have alot of fun trying different locations and other things in an attempt to make it work right......i like achieving success on my first try....but what I really like is all the stuff I learn from my failures.....my first stove will look like a hot mess of patches and cutting/welding repairs......but my second stove will be a masterpiece due to all I learned from trial and error on the first attempt.....by then I'll know what works and what doesn't, and what's practical and what isn't.....and most importantly where to stop over engineering ideas into it so that I'm able to stop at the point of sensible perfection.

[@davy1458]

Unlike my ability to stop writing at the point where it would have been a sensible amount of dialogue.

[@S3145]

You might want to put a prv (pressure release valve) on that. You could also add in a parallel path for some of the water to bypass the heater. Then use an anti-scald valve/cartridge like in a standard shower valve.

[@lornebruce8200]

If you use soft copper tubing and wrap it around the stove in an upward helical you will operate much more efficiently. Also you can use an old water heater tank to store your hot water in for days. When you run out just make a fire on again. Be sure to plum your up tube of storage tank to the upper end of your heat coil and the bottom to bottom. This allows for the system to work with no power or pump to heat the water. Only need to pump when showering from the reservoir tank.

[@digimaks]

Don't forget, she has garden hose going there- in which case when steam builds up, its pressure gets compensated by stretching walls of garden hose. It sure can pop tho.

[@pieterjlouw]

The Gardena fittings will slip off the hose long before the pressure gets dangerous enough for your over-dramatic "steam explosion / big bomb". If this happens often enough the inconvenience will probably demand upgrades to the pressure handling (else, if it ain't broken, don't fix it!). I like the mixer idea, but then again, it's a rustic outdoor shower and as long as you stand clear for the initial hot water coming out, you can control the heat of the shower by adjusting the flow rate at the tap where the hose on the input side plugs in to.

[@ducomaritiem7160]

I stopped at 7:18 to ask you the following question: Why not buy a coil of soft 15mm copper pipe, coil it up until it fits INSIDE the stove, make two holes to lead the pipe ends outside, and Voilá, no soldering and a very high efficiency factor... Copper can easily resist the fire temperature inside the stove. Ok, your outside copper pipes look more interesting tough.

[@Gunbudder]

I had the same thought. This is a fairly innefeciant design, but it is esthetically pleasing. Also she wont be able to touch or move the unit while in operation. You could go on forever making this type of heater more and more efficient, but you get diminishing returns pretty quickly. I would add a blanket, but that's about it

[@BenRyherd]

My thought as well, because screw having to make that many connections. She also needs a "T" off the spigot so she can have a cold line and use a standard shower mixing valve. Then she can control the temperature live rather than having to build up or partially douse the heating fire.

[@maxximumb]

Glad it wasn't just me that thought that.

[@herbertsumadchat9006]

Same as my Idea, just use a soft copper pipe and coil it. If you want, you can even put it inside your stove just watch the temperature. The design you made will trap steam at the top, if this happens it will boil off all the water in the copper pipe. You can also just make an insulated tank (at least 2" of insulation) and connect the input and output of the copper tube there and let thermosiphon do the work

[@dandeangeli9860]

If she puts in in the tank, it's going to get all gunked up from the resins and stuff she burns. Also she has taken advantage of the height of the stove. And: it looks freaking cool. Which begs the question: Are we making things for the outcome or for the making in and of itself and if yes, the cooler the thing looks (especially on video) then maybe the ultimate efficiency is secondary? Just a thought.

[@mightress]

Pressure release valve asap. Pressure in the pipes will rise fast. For temp controll use a thermostat tap like for indoor showers and mix with cold water for constant temperature of the water.

Yes - because there will be recognition of wood consumption (insulation = smaller fire) and the water may remain warmer for that little bit longer. The other issue is freezing water in pipes in winter..

[@satxsatxsatx]

Having tried to heat my house with a coal stove (MANY years ago), fuel is a huge pain in the ass. So an objective is reduce the need for fuel In your case, as you have guessed, smaller fire (less fuel). To minimize fuel, esp in those frigid German winters, heat conducted into the tubing would significantly be lost. I suggest, before next winter, than you figure out how to wrap the entire tank in insulation. I would wrap in hardware cloth or chicken wire first to allow hot to be trapped air around the pipes. Then wrap with, eg, fiberglass insulation Good work, creative and entertaining.

[@HeavyboxesDIYMaster]

Actually you could use a thermostatic valve. Combine the cold through a bypass pipe and the hot through the pipe you already installed. Then you'll have exact constant temperature always.

[@BrianSantero]

I was wondering this. Is this how typical showers work as well?

[@HeavyboxesDIYMaster]

@@BrianSantero ... Yes, public showers or faucets use thermostatic valves to guarantee no one will get burned from hot water. I don't know the reaction time for these valves to compensate but The hot water coming from her fire, should change temperature slowly as she uses the hot water up.

So it doesn't matter how hot the water gets you can always just add more cold water. It makes the system a bit more complex but I think it would be a lot more convenient. Great video btw!

Happy Sunday - cheers, Laura :) You may well need a PRV as your heat input doesn't exactly have super fine control .... fun build, nevertheless

looks good! I was wondering if coiling the copper pipes around the tank would be a less of a hassle? fewer joints to worry about. fantastic project though! keep it up...

Excellent! A solar time delay switch(valve) can be placed at cold water inlet and cycled every few seconds, when water reaches desired temp.mixed in one tank with cold water to achieve desired shower water temp, or run straight onto body. Blessings!

Wow, what you did is incredible. In the future I build it, it will be useful for my "downshifting". I don't know if you know this movement too.

Great creativity, and talent to think about how to create something for off the grid , there are many ways to do a water heater , and you made one ...

Again with the Fallout aesthetic... I like it a lot! Loved how you hinged that access door, so simple and so brilliant. Out of curiosity, is it common to have existing graywater plumbing in Germany? It's pretty rare in the US. Usually there's just a single drain system, and a single clean water supply for everything from drinking to lawn sprinklers to flushing toilets. We're wasteful that way.

Very cleverly done. I've seen a few variations of the rocket water heater, this one is fab. 👏🏽👏🏽

The heat could start to weaken the solder joints. Just a thought you might want to coil the copper around the tank. You should get the same results with less expense and effort and you shouldn't have joint problems. Yes, the pressure valve suggestion is a good idea. Never the less you rock.

Honestly such a cool build! Great use of resources.

Someone probably already mentioned this, but the boiling water at the beginning was the water that sat in the pipes while you built the fire. If you run the water a little while the fire is building, it doesn't sit in the pipes soaking up the heat. Ganz toll!
