Hot Water Rocket Stove K Type Part 2

[@thelazycat_]

So your heater has a capacity of 20.902kJ/h. 5.58kJ/s, 1,55Wh. I think you have a decent heater. There are some possibilities to increase the efficiency, but good job!

[@gabiold]

Might be some international discrepancy in the fractional/thousand separators, but your first and last number is not right. The total enery was 20 MJ, -> 5.56 kJ/s = 5.56 kW. 1 kWh = 3.6 MJ

[@thelazycat_]

@@gabiold yes, depends on the numbers and significance you use. When I calculate it with the Cp of 4.186 KJ/Kg.K., you get 20.093 KJ > 20 MJ. 5.58 KJ/s is correct. When you use 20 MJ, you indeed get 5.56 KJ/s. The Wh is indeed wrong, don't know why the additional /3.6 came from. It's always good that someone does the calculations over. Good job

[@gabiold]

@@thelazycat_ I am not complaining by that 0.02 kW difference (I used 4.2 kJ/kg*K), but the wrong magnitude. You seem to have used dot as a fractional separator (as it should be in English) and if that's true, then it is not 20.093 kJ, but it is 20093 kJ which is 20.093 MJ (I just rounded to 20 MJ, but again, I am not hung up the precision). The other value in the original post 1.55Wh, which is not true, nor the unit of measure is right because if you want to express power then it is just Watts. Watthours is an energy measurement. 1 Joule = 1 Ws (Watt*second) 3600 J = 1 Wh 3600000 J = 1 kWh This last one from where that 3.6 comes from, if the units are MJ and kWh then 3.6 MJ = 1 kWh This is also why 5.58 kJ/s = 5.58 kW, because Joule is Ws, thus kJ/s = kWs/s = kW Easy to calculate that 3.6 conversion factor any time you want, but useful to remember as the burning heat of most fuels, woods, whatever are usually given in MJ/unit, we pay the electricity by kWh, so easier to compare prices, heating times and such in human-friendlier units.

[@gueacil7131]

Sometimes i got bored on project video without naration or without detail explanation of what, why or how.

[@hyselwatchandclockrepair1874]

I appreciate the running narration of what you are doing and thinking out loud because it gives me better understanding of why you do certain things the way you do plus it helps keep the focus of what you are doing much better. Please don’t change your approach to recording what you are doing and why you are doing it. Your videography is superb and your down-to-earth approach is extremely helpful especially with your narration. Thanks so very much for sharing your thoughts and your skills.

[@DrLove911]

My 7 year old niece Emily died Oct 9th . She loved Pepa pig. I'm glad that was in this video. Made me think about things a little different. Great water heater.

[@LittleAussieRockets]

Life is so precious, thanks for sharing

[@leighharvey9150]

Not getting to enjoy your pie is about the most relatable thing ever

[@jessebarclift8533]

You want your water tank higher than your stove and you want to draw the water from the bottom of the tank and the return line slightly above center mass. That's how hot water heaters create thermal layers the bottom is always the coldest with the hot being on the top layers (heat rises) hook it up like that and I think you'll have the best rocket water heater I've seen yet. 👌🏼

[@loucinci3922]

Its nice to share with your little ones. Enjoy them while you can. They grow up so fast. Made me smile thinking about my two (18 & 16 now).

[@GreenShortzDIY]

Meat pie breaks in every video. :-) Enjoying the rocket stove builds. Not surprised that you are a pro sheet metal fabricator, because your precision on the metal work is impeccable. Glad your KZbin proceeds were able to fund your folder, what an amazing tool and great time saver...a good investment for sure. And for your cardboard cut out method to get the odd shape figured out, a proper "good on ya."

Amazing. Love the way you talk and work and thanks for sharing 💗

[@ianmoore525]

When u had that problem towards the end, I thought it was the same mistake I made plumbing up an old crown *5 semi combustion stove to my old 30gal hot water system. Had the top pipe too close to the top on water heater, it used to bubble and boil when it was cranking. Still worked for years. Prob nowhere near as hot as ur rocket stove. Great vid 👍🏻

[@GuitarAveragePlayer]

I enjoy seeing your family in the video. Your girls are adorable.

[@thomasbrooch8697]

Plumber here and you're right it was heating faster than thermal siphon could move the heat out of the exchanger, so it was flashing to steam. If you start making those things just make the next one with larger pipes if it is supposed to be for off grid were you have no power supply, also in the past when they used thermal siphon in this manner, they would use a insulated tank and hang your rocket stove or burner right on the tank, the shorter the runs the better siphon works. If off grid isn't a mandate than use a pump and consider piping cold to the top of the exchanger forcing the water to go down against the heat it will give you some efficiency gain. I'm from New England and I wish I knew a metal worker/ welder with your skills, nice build! Hope you get the bugs worked out with your new heater.

[@mrf5347]

Awesome craftsmanship! The kids remind me of my 3 daughters! God has blessed you greatly, may you cherish your family to a great old age!

[@Pats-Shed]

The thermo-siphon only works if there's a steady rise from the top of the stove outlet to the hot water tank, otherwise it'll vapour lock at the top of the stove . A cheap source of 12vdc pumps is a Toyota Prius inverter coolant pump, low current and submersible if you seal the electrical connections. This stove is turning out very nice , keep up the good work.

[@RangieNZ]

Yes, the big 'downwards loop' after it comes out of the top heater port is the problem. Just use a straight length of hose, preferably on an uphill gradient, going towards the barrel. That may also mean, you need to lift the barrel slightly (- say on a pallet), to get the rising gradient on the pipe.

[@blueboi5000]

This should be sold in a shop. Great work.

[@sarcasmo57]

Reminds me of the old folders we had back at school. Perfect for sheet metal origami. Love your work dude.

[@spankitout]

They are called a brake, but dont ask me why.

[@southern0949]

Hot water always rises. So the top outlet pipe from the top of the heat exchanger needs to constantly rise to the top of the storage tank (even in your heat exchanger have a sloping annulus ring to a rising outlet pipe. Have no pockets where steam can be trapped). Similarly, the cold water feed pipe at the bottom of the storage tank should also rise to the inlet of the heat exchanger (this water will eventually get hot too!). These inlet and outlet pipes should be lagged with insulation as well. Also hot water expands so the heat exchanger outlet pipe needs to be a larger diameter than the cold water feed into the bottom of the heat exchanger (experiment with 20mm cold in and 25mm hot out say. You also want to keep friction loss down to aid thermosiphon). If the flue is too hot make the heat exchanger jacket longer and take out more heat. Your heat exchange jacket design is the right approach compared to say copper pipe wound around the flue or in a water tank as this too easily creates steam and danger of pressure buildup. Excellent build by the way and great helpers!

[@emjay8387]

Love your metalwork! Brilliant! Regarding the thermosiphon, they will always vapour-lock if the water boils at any point in the tube. Forgive me if i over-explain, but the liquid water will expand as it heats and start to form bubbles of water vapour. If those bubbles can’t get to the outlet as small bubbles, they join together into a large bubble that takes up the whole diameter of the tube and the thermosiphon (or any siphon) will be interrupted. This will then compound because the water will stop flowing, be exposed to more heat, and boil even more. Boiling can be avoided by increasing flow rate. This could be by having a tube with a large enough diameter that bubbles can always get to the outlet before they block the tube, or by pumping water through faster (but then you need power). You will avoid boiling longer (i think) if you pump the coldest water through, that is if you pump from the bottom of your tank. Boiling can also be avoided by reducing the water’s exposure to heat; either have a smaller burn chamber or have fewer windings of your copper tube. Any thermosiphon system will need a bit of fiddling to maximise performance. Top quality build though! And thanks for the great video!

[@johnswimcat]

Superb metalwork and I really like that you didn't chuck the chicken off your lathe to part off. I have a Bosch metal cutting jigsaw which I have to say is pretty good. I'm amazed that you can use a grinder with such accuracy. Cutting a circle or ellipse with a flat disc, wow!

[@rowanbrecknell4021]

I rebuilt my Solar Hart in 2009 hot water system. The tin trays were cheap. The most expensive part was I put marine perspex on to cover the trays. Knowing now all I would do is make tin tops. I would go all stainless steel for the heat traps. Copper vacume tubes would be the go as well to cut down on water flow and joins.

[@harryendawypknightly7291]

Spot on nice to watch a professional job by an obviously a good craftsman

[@trevorcochran2173]

love watching the build. It has given me some great ideas! In the comments I have not seen anything about your heat extraction position and I believe that is your biggest inefficiency (that and the fact that 95% of your heat is lost up the chimney. Would it not be significantly more efficient to not extract the heat from your burn chamber? Every degree you lower the burn chamber is another level of tar you cannot crack which leads to waste and smoke and ash. The reason people add insulation around the burn chamber is to jack the temperature up to 1800-2000 °F where wood will fully burn, not to increase the heat transfer to the water (though I guess it has that as a modest secondary benefit). You can then use the extremely hot exhaust gasses in a downdraft configuration to shed heat into your working fluid. Of course, that will also burn your stainless, so you'd need a refractory liner. Also, I think Perlite is the perfect insulator for what you are doing. Cheap and light and where rockwool burns at 900 (and the binders well before) perlite can hit your 1800 and keep right on ticking.

[@paulinebayly1024]

[@tonyurquhart8278]

Hi Little Aussie Rockets, I just discovered this channel. Love your work. I also saw the hot water boiler you built last Dec. I built a similar thing some years ago. Ver 1 was about 1993 based on a water boiler or "Donkey" which we used as Cadets when at high school. I have been helping out at a school camp for 20 years where they use fires to cook. I take my water boiler so that all the campers, seasoned & rookies can get some hot water. I used a copper tank which originally went over the fire. Then around 2004 added a "Heating Coil". I used 4 turns of 1/2" copper tube bent to about a 250mm diameter (so about 3m of pipe in the fire). I plumbed the bottom of the coil into the bottom of the tank & the top (hot supply) line went into the tank about 1/2 way up the tank. The coil simply sat in the fire & you could cook on it too. The tank was closed except for the "Overflow" spout which is where you got the water out, plus it had a large funnel on top with an internal pipe that made the cold water spill to the bottom inside. the tank was full to overflowing. The coil heated & circulated the water & when you wanted water you poured in the amount required of cold water into the funnel & the same amount of hot came out the overflow. Still use it ti this day. I am happy to send you a photo if you are interested.

[@notsoniceduck]

I love that you use just a few tools and you sure are an artist with a grinder. :)

[@murmur3966]

You could add in a one way inline check valve to force the thermal siphoning to flow in the proper direction and stop it from turning to steam. Then it will get the lower cooler water feeding into the heater through the valve. Great stuff keep up the awesome content.

[@keithsyers5833]

Sorry me again I've just had a look through 200 comments and air nibbler was mentioned a couple of times a cheap one around £30 $Australia 40 ish. One comment has a 20mm bore pipe to middle of tank so the hot water rises and cold water out from bottom a couple said tank above boiler and straight pipes. A couple of questions does it get really cold. Do you want hot water all the time if you want use the system indoors to run your central heating with a high flow pump and indirect water heating. You've got it so right. You're an artist thank you for teaching me something I hope I have helped you

[@iant5909]

CRITICAL: The supply line from the heat box to the storage resevoir needs to be POSITIVE angle, upward slope all the way. Heat (incl. heat in water) only travel UP hill. Any down or negative slope in the line will cause AIR LOCK. Even if just 1 degree it will work, but MUST be 1 degree POSITIVE. Any down or dip in pipe ( as I saw in video will fail). CRITICAL: A plumber experienced in connecting wood stove to HWS did my fire box years ago. He said this is the most common fail that amateurs make. Supply line must be all uphill.

[@stevenboughner7255]

Great Build! I've never seen anybody basically free hand cut a hole with a grinder. That is one of the reasons I subscribed to you channel.

[@LittleAussieRockets]

I cut toilet flange holes with a rip saw the same way lol , i guess im not the only one cutting round holes with a strait cut saw lol ...

[@edkleindienst]

It's amazing what you can do with a grinder!!

[@freezerlunik]

You have to have the heat source below the water tank *height-wise* for the heat siphoning to work well. That was your main issue, other than not taking care of the kinks in the hose. Amazing fabrication and rocket stove heater, though. Tip of the hat to you, sir!

[@HK-fu2oe]

[@AutoHoax]

As a plumber when I was working at mechanical shops I always envied that tin benders , fabricators and pipe fotter welders got to work with so many different machines and tools that we didn't get to work with. A carpenter or auto mechanic never interested me much but to be able to take a roll of metal and make the ducts or other projects they would take in when the normal work slowed down was impressive. As a full weld metal shop they could basically do almost any type of metal work. They had ever type of welder , roller, break, guillotine, gantry fabricator tables. The mathematics of building a eccentric or concentric off set out of any material or thickness of metal is an admirable skill set. All rhe new technology is cool and interesting but the job description that is being replaced gives one a melancholy feeling. To know that so many of our kids and grandkids won't have the experience of a har days work because that type of work has been offshored or a machine can do it much more efficiently and cost effective.

[@LittleAussieRockets]

Funnily enough the grinder is my goto tool for pretty much any job i do, 4 inch 1mm discs cut through anything and when i need , a diamond wheel, great on wood metal plastic anything you need cut a angle grinder.... Its good to see you use different tools for stainless and ferrous metals so many people over here in spain dont have ac lue and when i order a bit for a boat it rusts after a couple of weeks as they have contaminated it with a steel cleaning belt or polish wheel and once its rusted its almost impossible to get it off.

[@eby6114]

[@JayPlaehn]

Thank you for sharing your learning curve and experiments very clever Living off grid for 15 years now I have built two in line on demand wood fire hot water heaters - I have spent so many hours thinking how best to easily and most inexpensively improve my last experiment - my first 50 foot 3/8 copper tube inside an old wood stove oven retrofitted to run the flame over the fire box then through the 5 inch shelf with copper coil to standard 6 inch chimney works great but 1) slow tub fill 2) tub does burn out after a few years of use here and there not daily but a lot - my second all steel double long 5 gallon propane tank inside a craftsman air compressor tank making a full water jacket works great faster but the water is not chrystal clear as with copper tub (or a stainless) it is better now just fine me on season three as it fully rusts in but the hole point of off grid spring water outdoor tub is “Chrystal Clear Water” especially if I have female company - I also took a conventional 5 foot cast iron tub with square lip on top and built a fiberglassed double 2x4 extender top that I silicone sealed to the tub making it much deeper with head rest and foot extender shelf - at 6 foot 5 I can fully float and soak for hours in the rain or snow or clear nights - when cold it takes a lot more wood to keep it hot - for me the key is an open in line flow system where the control valve is on the inlet for heat control of flow and safety as the system is always open and can not build pressure

[@thomasgreene5750]

A few suggestions you might wish to consider that might help you get the system to naturally circulate and the water inside your barrel to mix naturally. 1. For a thermal siphon to work stably, the cold reservoir (your barrel of water) must be at an elevation above the hot reservoir (the heater inside your stove). Try raising the bottom of the barrel a few feet above the elevation of the hot-water outlet connection on your stove. 2. To naturally mix the water inside the barrel during heating, try connecting the hot-water outlet hose from the stove to the center of the bottom of the (raised) water barrel, with the flow into the barrel directed upwards. Make sure that the hose continuously slopes upward from the stove to the barrel (no dips). The closer the hose is to vertical, the better the circulation. 3. Try placing a sheet-metal cylinder inside the barrel with a radial clearance of 4 to 6 inches to the side of the barrel. The cylinder should extend from the bottom of the barrel upwards to about 1 foot below the water level. The cylinder forces the hot water returning from the stove to travel a long distance through the barrel before it can reach the connection supplying cool water to the stove, giving it time to better mix with the water in the barrel along the way. 4. Continue to have the connection supplying water to the stove connected to the side of the barrel, but try moving its elevation down from its current mid-barrel elevation to an elevation about 4 to 6 inches above the bottom. This should provide the coolest water to the stove and increase the driving head for the thermal siphon. Assure that the supply hose slopes continuously downward from the barrel to the stove's cool-water inlet connection (no dips). The closer the hose is to vertical, the better the circulation should be.

[@masterdebater8757]

Correct elevating the reservoir will work, but also adding a brass swing check in the cold water inlet side of the boiler will also stunt the thermal expansion and allow the thermosyphon to happen undisturbed.

[@checkedoutchris]

I know I'm late to the party. Great video though! Love the little family time vignettes. 😀 Also, good job on the work. I'm a proponent of making my own improvised tools and enjoy watching folks who aren't afraid of building their own stuff if needed. Please keep up the good work!

[@keithsyers5833]

I love the stuff you are doing the hot water thermal cycling try putting the tanks 3 foot above the rocket heater and insulate the pipes maybe wider pipes the pressure of the water will stop the water from boiling and carry more heat through the pipes I'd love to see it working well . My uncle had a back boiler in his coal fire the water tank was 4 meters above the fire and boy the water was very hot

[@craigsymington5401]

Mate, if I didn't know better I'd say that you could do this for a living. You inspire me. I have followed you from the beginning and enjoy all aspects, no mind the talking. Not too much for me, usually I talk too much. I'm gonna have a workshop next to the house again as I've moved out to the city and will be building rocket space heaters and so on again. I'm a full calendar year in Auckland. It's been tough but it's all starting to make sense and feel like home😆 Accents are not so noticeable anymore, so you sound more "normal"😉. Boss got us a multi machine. Next gas, then tig torch. Can't wait to "play". Loads of scrap cylinders, drums (and scrap yard near) and pallets to turn into things...

[@roncook8409]

Great craftsmanship. You don't see that much anymore, these days. I really enjoyed watching this. My favorite was the use of the grinder, as if it were a jigsaw (nicely done). That 'flange' is called an escutcheon plate. in the U.S.A., well, in the 'Plumbing Trade' anyway.

[@natsirim499]

Great to have the C/H water ports coming from One Side of the unit. Fantastic.

[@atomicsmith]

Awesome craftsmanship on the stove! Try running the hot outlet more directly to the upper barrel inlet (take out that sag in the hose). The way you had it configured created a heat trap where the cooler water settled in the sag and prevented warmer water moving through easily. This is similar to a bell stove effect if you're familiar with that. Water was lingering too long in your heat jacket and boiling. I would also avoid using those right angle connectors if possible, the thermosiphon effect is fairly weak and the shorter the distance and fewer bends the better...

[@alexalvarez2495]

Usually, to avoid thermal shock, you might want to flow water downwards... Anyway, your design and accomplishment seems outstanding to me... congratulations!

[@K4K96]

Brilliant craftmanship.

[@ElderlyIron]

Like Grampa used to say. There's more than one way to skin a cat, but no matter how you do it, the cat ain't gonna like it! You're building a rocket water heater, you have a chicken on your lathe, you eat meat pies and your wife brings you kefir. You know now that I'm gonna HAVE to subscribe! By the way, you can daisy chain 3 of those 4 foot LED "florescent" lights for probably the same cost as the high bay light. Just a little something to put in the back of your mind, wild land fire shelters utilize aluminum because it reflects 98% of radiant heat. I have aircraft aluminum sheets about my wood stove on the walls. Works a treat! Anya Ha Sayo!

Love ya videos, keep em coming! The upper outlet pipe had a dip in it, it has to constantly rise or it wont thermal siphon. Been watching many rocket stove videos lately looking to design one to heat water on my camper trailer (Don't want to use non renewable Gas, using induction cooker, solar etc) and have watched most of yours and this one, well its almost perfect mate. Quite well designed and some great skills showed off in the build process (Not to mention the great memories you are making with your family, makes for a great story for us viewers).

The chickens probably make for tasty meals :-) In order to keep that heating unit producing heat it needs a steady source of wood, good for a bath, or cooking, but you'll need to shower fast because I've gone through a lot of wood with the rocket stoves I've built, and it didn't take long to burn thick wood.

Just found your channel and I love you craftsmanship, but more than that is your beautiful family, had a hard time with the accent since I am from South Louisiana. I subscribed to your channel can't wait for next videos.

You are obviously a metal artist! I really, truly need one of these in my life (off grid, homestead, mama to 5 kids). Is there a chance you would make one for me? I would happily pay for your time and effort!

Decent build, good on ya. Thermo-siphon would likely work with correct setup... basically hot cold tank needs to be higher than the stove.
