Fill the system with glycol. Then you won’t need to bleed it out each time. You will need a couple of isolation valves on either side of the disconnects so you can transport without losing much of the glycol. Awesome project, very impressive!

[@Linuxhax]

Propylene Glycol.

[@DBuss-om8sh]

That's what I was thinking too. But can glycol can be heaten up that much? Is it the same than Prestone?

[@odw32]

You could make some kind of a "cupholder" hole in the top of the ammobox, so you can partially submerge a food-safe aluminum bottle/canteen. 70-80c is certainly hot enough to heat some water "bain marie" style for warm drinks or reheating soup.

[@johnsellers2999]

Ok good idea you have there. I would also have a propane back up heater because you never know when that copper is going to break. And I'm betting it's gonna break on the coldest night ever. To not have a back-up in very remote and cold place can be a real serious problem. Wish I was young enough to play like that. My mind is for it but my body might not be strong enough anymore. But very cool heating system I must say

[@ShaneZettelmier]

There are lots of ways you can deal with the pressure, almost every house hot water heater deals with it. You can buy a pressure tank which is about the size of a soccer ball and it’s got kind of a bladder inside so when your pressure builds up it gives room for expansion and then as it cools it keeps a Tanks and all that from collapsing. The way to get around your valves with the rubber seals is to plumb it. Basically make a permanent radiator inside the camper and you can have a second water tank outside or an insulated tank outside and you can sweat or brace everything together so you don’t have to worry about seals. You can get hot water rated valves and put them outside, you could even put them in an area where you can pile of snow on them but outside they were cool a lot better. You can do things like insulate your pipes running over to the fire, you could have a smaller fire or build a specific stove to heat it like a little rocket stove or build A small wood stove with a flu and tight ventilation system to keep your wood-burning slow and not as hot all night. Another thought is you could do a fire pit and have wood set above it on the shelf and after a few hours you could just yank on the cable and dump that wood in the fire pit to keep it going longer. You could also have an external tank that you could mount on the exterior wall and insulate some and you could have that work like a boiler and put a small car radiator or something inside, maybe even a small motorcycle radiator. I like the idea of just using wood and mechanical devices and not needing electric but you could wire your snowmobile and or a small generator to charge a battery and you could heat the water in the tank with a diesel glow plug, you’d be surprised how much it will heat it and that way you could put it on a timer or even a thermostat and the car battery should run that for several hours. I’ve seen people make a water heater with a 55 gallon drum and heat 55 gallons with two small glow plugs within an hour or less. It would probably heat your ammo box in 10 minutes end it wouldn’t take much to put a thermostat on their aunt be able to control your temperature very well and make it last a long time. Since you’re pulling it with a snowmobile you could run wires off of the alternator through the trailer hitch and charge your battery that way and not need a solar panel or a generator and you would always have a battery back up for your snowmobile as well. You could even mount a couple of batteries on the snowmobile and use that to power the heater and lights in the camper. I love these projects, it will be fun to play with overtime and make improvements on. Now you’re gonna have to work on an air conditioner. ;)

Here is a thought: thermo floor heating run tubing on the wood floor and insulate the floor Like in a house. The floor will heat the camper and your backside while you sleep

[@Beltloop29]

I was just thinking the same thing. Rarely reply to these things but thought I should on this. Copper lines running back and forth either under the floor above the insulation or could be the wall. May be able to control the flow with another valve on outside or just inside with partially closing it to help control the temp. Also use some insulation on the pipes outside to help keep them from bursting. Maybe get a few fire bricks to set up just under the pot on the fire and possibly put some cobb around it to help further keep the heat.

[@Beltloop29]

Could still be used in combination with your ammo can.

[@alexanderheling2057]

Now, that is a tiny home!

[@pixelbasedlifeforms]

The design can be improved IMO. You can attach a small woodstove to the one of the outside walls with the pipes already in it. Pipes could connect to the radiator on the other side of the same wall, inside the cabin. This way the pipes could be super short preventing the heat loss. It could make it much easier to use as well. You wouldn’t need to set anything up. All you would need to do would be to put the wood inside and start the fire.

[@letrainavapeur]

Take all those kinks out of the flexible pipe, shorten the copper pipes and insulate all pipes. To control the temps just put less wood on the fire. Need to remove the valve from the vent line or one day it's going to be left shut.

[@Talkingworms]

My thoughts exactly. There are too many ways to build up pressure in the hot line and effectively creating a pipe bomb. An inline pressure release directly following the copper pipe would be my first safety add. Also, this is extremely overkill for a space that seems to be less than 50 cubic feet. Just insulate, then heat a pot of water and pour it into the ammo can.

[@letrainavapeur]

@@Talkingworms The traditional way, at least in power stations is to fit a pressure relief valve to any pressure generator without any means of disabling that pressure relief i.e. valves. I would also be quite wary of that pressure relief valve operating in a water filled line since it would emit very hot water.

[@Talkingworms]

@@letrainavapeur A very good point. Honestly, I keep going back to "just heat the can of water, put a little insulation in the walls, and drag the can inside as a considerably massive thermal sink." Or even safer- skip the water and go directly to sand.

[@letrainavapeur]

@@Talkingworms How about using some thermal bricks as used in electric storage radiators and just heat them in a custom frame on the fire, easier to handle and transport.

[@Talkingworms]

@@letrainavapeur Perfect.

[@smpb238]

way cool . if i may add a thought ,it almost looks like you need to build a rocket stove kind of thing on the front of your sled so you can keep that system installed all the time. then run some coolant instead of water so it can get cold.

[@rveurope]

Thought the same, a little boat oven with a metalbacking would heat the camper as well when you have 2 metalsheet backing you get a convection inside and you can cook on the out side..make a little flap over the stove and its all weather proof

[@Imnotyourdoormat]

Xtra-kool, the cons you mentioned can be refined, still a great prototype...i was thinking anti freeze, clear fuel-type filter, a few anti-freeze tester balls to monitor flow, pressure cooker popoff or mr. beer machine valve instead of the vent. maybe a quick mount on the shed itself for usability and unclunkyness. i can think of 100 more im sure you can too...outstanding job kutgw.

To set up a camp for a number of days you could add some anti-freeze to the water so there is not as much risk of the lines freezing.

[@GordLamb]

I'd weld copper pipes directly to the radiator inside, permanently mounted, to faucets outside the camper, with self-sealing quick disconnects. Replace the pot and coil with another ammo box that sits near or over the fire. Fill the whole system with antifreeze, and just hang the exterior ammo can on the side of the camper when not in use. Should be able to just grab it off the wall, and set it next to / on top of the fire and be good to go! Could also put a radiator / heat sink on the outside of the camper with a mechanical bypass thermostat; if the antifreeze exceeds a certain temperature it's rerouted through the heatsink to cool it off and regulate the temperature.

[@wannabeagamer1204]

As someone watching this from America, thanks for the temp conversions lol. Also, that is an amazing idea. I think it’s practical for camping, would be good for a pop up camper if it had a fan behind it.

[@Lee-qp6gf]

Add a couple of magnetic thermometers to the side of the tank. You could tell what it's doing. Good luck, Lee

[@dlsdyer9071]

As far as adjusting the heat, you could use a vent arm like we have in our greenhouse that automatically opens when a certain temp is reached and closes when it cools.

[@TheOutsiderCabin]

Interesting idea!

[@romeorozeta4998]

Or perhaps something similar to what an automobile uses on the water line.

[@allamerican6094]

We have those arms on our greenhouse also.they work very well.can adjust them to desired temp.i think we got them from Johnny's greenhouse supply

[@monkeysuncle2816]

Or a secondary water line, with isolating valves, to shunt the unwanted heated water outside to cool it off.

[@josiahstevenson]

If you rotate your coil bucket 90 degrees so it's on its side, you'll get a lot of convection flow in the line - probably enough to switch the inlet and outlet and still have the water circulating a lot faster.

[@bearrivermama6414]

Great job. I enjoyed watching your ingenuity come to life! I'm sitting next to my fireplace watching with the temperature outside at -49* so my appreciation for the heat you created is at a heightened level! 😂

[@BrianBriCurInTheOC]

The correct definition of Water Hammer - Hydraulic shock (colloquial: water hammer; fluid hammer) is a pressure surge or wave caused when a fluid, usually a liquid but sometimes also a gas, in motion is forced to stop or change direction suddenly; a momentum change. This phenomenon commonly occurs when a valve closes suddenly at an end of a pipeline system, and a pressure wave propagates in the pipe.

[@paulsojourner7551]

You could also run copper tubing in a zig-zag pattern in the floor or one wall of your snowmobile camper with screw on connections on the outside of the camper. Connect one copper line from the heated water line so that the hot water travels through the camper before exiting and going to the tank. This way you don't have to store the hot tank of water inside your limited space camper and you get radiant heat. Could also add a faucet line from the hot tank and one from a cold tank to a dual valve and have temp controlled shower outside.

[@heywhyerd]

You can insulate the copper piping for better results and more residual heat except if the lines are allowed to freeze up at any point which would cause longer system start up time. You can also install a heating element in the ammo can hooked to a solar panel on the roof to deep cycle 🔋 battery for daytime use.

NIce design. You can regulate the temperature with a standard plumbing thermo bypass valve, which will open at a preset temp (usually 38 C) of you can dial in various temps. Also, a pressure relief valve should be added in case you have a steam surge. Ive built engine exhaust water heaters for diving.

[@wessmith7408]

I discovered your channel yesterday and I love it. Knowing this is 4 years old, I’m an old heating expert. Adding something to the water to keep down the boiling point is how a boiler works. Next, find a long hot water baseboard heater. It would need to be mounted inside the camper at an angle on the wall. This will make the inlet higher than the outlet so nature and gravity do all the work. These are small and light weight. This would distribute the heat more evenly. You could mount say a 2 1/2 gallon container on the wall just head of the baseboard heater. This would be your water supply, much like your ammo container but smaller. This should eliminate the need for so much water. This is a thought and I am quite sure it would work very well. I also thought you may want to remove the outer cover of the baseboard heater and just use the coil inside. If it isn’t too bulky, leaving the cover on would make it more efficient. Leaving the cover on will also eliminate the boiling problem. Either way, this would work quite well. In your area, I am sure there are many hot water heating systems in use. I’m in love with your channel and all that you are doing. If interested, I’m almost 3/4 of a century in age.

[@sacredcymatics9550]

Closed circuit loop for transportation, fill with propylene glycol. Locking ball valves on the tank and use braided lines with locking ball valves so your lines maintain glycol. Having an open vent like that automatically bleeds the air properly from the loop and you've vented it at the systems highest point which is correct. Ultimately what you've done can remain an intact or disassembled fully portable heat source that does not require filling or draining with every use. Simply apply the few suggestions I've offered and see for yourself. Excellent video thanks for sharing.

The Outsider, Tip, if you add Heat Sink Finns to the side of your Ammo tank it would give off heat more evenly and better, Also you could add a second one way valve and make a inner loop that you can turn a valve and send half the water back to the pot bypassing the ammo box. That would let you regulate the heat.

[@jameshelton8095]

Thank you for sharing. Cool updates. Couple of thoughts- 1. add some pieces of stone (soapstone or granite countertop scraps) or ceramic tiles to the outside of the water can to increase"battery" size. 2. Once you are happy with placement, consider replumbing so that the valves are outside and solder pipes directly to water can so that should the seal fail, the water will go outside, not on your stuff. Shouldnt be to much an issue having the valves outside since you have to go out when you shut it down anyway. 3. Add one of those fans for wood stoves since they operate from heat and not electricity. Better equalize the heat inside. 4. You could use a metal tripod and some chain to allow you to alter the height of the fire bucket to allow some control of heat. 5. Not doubt you already considered that you can add an additional coil to the inside of the water tank to allow you to make drinkable hot water, plumb it to a metal pot on the outside of the water can and you are good to go. Would also let you increase humidity inside during dry winter. Could be fun to experiment with. Could also just put a pot on top of the water can (grin). Take care

[@kennynoble1223]

Thanks for the ideas! A couple of those ideas will help me build and use my own heater. I'm about to make myself a primarily recyclable-based home made paperboard chunk/waste wood chip/sometimes charcoal fueled window mounted space heater similar to this, but smaller. I think I might use a modified kettle grill (not a camp fire), a modified old and scratched up pressure cooker as the boiler, copper tubing as the coil and sand inside the pot like what you did there, and mine already has a sort of check valve so I can pressurize it for more efficiency. The space heater's window unit will probably be on the ground floor. It'd probably be a modified box fan with insulation around the edges and on the back of it. The back would be sealed with plywood or whatever's handy, 12 short hose sections would be put through holes in the fan box behind the blades, and routed to draw air from several inches beside the front of the fan. There will be a copper coil fastened to front of the fan with coat hanger wire. Hotter water will go through copper tubing from the top of the pressure cooker, through the top of the grill through the sheet metal window mounting bracket and insulation. It'll go into the top end of the larger diameter fan-front coil via coupler. The colder water will go from the bottom of the front-fan coil through another coupler, through the side of the grill's lid, and through the side of the pressure cooker. All points where pressure could escape will be sealed with gasket sealant from the inside (where the pressure's trying to escape), and all heat sensitive parts of the build (like the parts of the tubing that'd be attached to the fan box or near the window) will be wound with exhaust wrap. In the Summer I can use the grill for cooking and the window unit + a modified cooler or mini fridge for keeping soda cool and replacing my conventional AC on days that are just a little too hot for fans. Next year, I can make another space heater with 3 Fresnel lens boiler, blue or black dyed sand, and used frying oil to the system to track the sun and provide solar heat at another window. I'm doing this not because I think a small space heater or 2 will replace conventional gas heating, but because there's always a 10-15 degrees F. difference between my neighbor's place and my place in this duplex, their side is that much more efficient than mine, and the furnace is working too hard to keep me warm in Winter, too. I want to supplement the furnace without raising the utility bills much like I'm doing right now with a conventional forced fan space heater. It's up to the landlord if they want to insulate my place better or not, but it's up to me to decide how to keep warm until I get out of debt and get a new place, I est. about 5 years from now. In the meantime, I'm on a tight budget. There's also a building code, here for permanent builds/alterations to a property. I also don't want to either upset the landlord or do them any favors. When I leave I'm taking my heating/AC system with me, so I can continue to save money on heating and AC. Those are the reasons why I want to build a cheap and portable heat/AC system piece by piece. I'm in Iowa, so we have about equal need for both, depending on the time of year. Migrating for the seasons would be more expensive, though...

Awesome. What about 1. Some anti-freeze in the water 2. Permanently fitting the ammo crate in the camper with quick release valves on the exterior walls (Just for a quick set up)

[@Valkaneer]

Yep, that's what I was thinking anti-freeze I think would work well, basically like a car heater.

[@Bluetoothedshark]

Build a mini log burner from a fire extinguisher, wall mount it, run it on kindling, chimney out the top, you could even build a back boiler from a gas canister or something and have hot water...

[@Rokomarn]

lol but that would actually be efficient and convenient.

[@barefootralph8467]

I know you discounted the use of cast iron radiators but have you thought of using a car or truck radiator, they already have an inlet, an outlet, a relief valve, and It disperses heat well. In floor or in wall piping might help too if you are still looking for improvement options. Congrats on the great job so far.

[@jeffweber8244]

BareFoot Ralph Yes, perhaps a radiator from a “crotch rocket” inline-six motorcycle would be about the right size and weight for the task

[@Baer1990]

Might be an idea to make a 2 sided coupling through the wall with 2 caps then you can vent the pressure (or prevent a vacuum) even when you packed the coil away without having the top tap open leaving moist air out, and the top vent of the cabin closed as well

[@tangoindiamike9189]

Suggestion. Build a small enclosed insulated box on the end of your camper to house the ammo can heater, with a little space around it. Install a small solar powered fan and thermostat with some type of flap vent into the camper. A small computer fan would work. The thermostat will require minimal power, and the fan only needs to be strong enough to blow some of the warm air gently into your cabin space through the flap vent. Think about how the vent cover for a clothes dryer works. When warm air is blown against it, the flaps open and allows the warm air to pass through. When the dryer stops, the flaps close. So when the temperature in your cabin reaches the set temp on the thermostat, it turns on or off the fan and the flaps open or close. You could probably get by with the small 6v or 12v battery typically used in deer feeders. It would add another component or two to your kit, but it could all be permanently installed on the cabin, except for the coil and pot, and the exterior water lines. Get the light flexible solar panels that are used on sail boats. It may weigh a pound. Adding a permanent, insulated compartment for your heater will add some weight to the cabin, but it will reduce weight and occupied space on your snowmobile, and will also reduce your set up time. With the can already inside a compartment, and strapped in, you could install hook ups directly through the compartment walls. With a hinged lid on top of the compartment, you can easily add water or snow to your can. Then just hook up your hoses from your wall connections to your pot, and you're all set,...except for the fire, but you'll always have to do that step. If your battery, thermostat, or fan ever fails, you still have the option to move the can inside the cabin. You are welcome, and as a footnote, you may not need a solar panel and battery if you can figure out a way to use energy from the heat to power the thermostat and fan, but voltage would have to be regulated, perhaps through a small solar charge controller,...but then, you would need to be sure you don't exceed the input limitations on the charge controller. Ok, I went out there a ways. Just stick to a flexible 100 watt solar panel and a small battery. I recommend the 12 volt, 7 amp hour battery for deer feeders. If it turns out to not be enough to run the thermostat and fan through the night, get a second battery and wire the two together in parallel to maintain 12 volts while doubling your amp hours. The ammo can, connections, solar panel(s), charge controller, and batteries, can all be pre-installed and ready to connect the lines to the pot. Harbor Freight has a cheap solar charge controller to prevent overcharge of your batteries. Just my two cents. Good luck! Edit to add: Here is how you wire it. Solar panel to charge controller, charge controller to battery, battery to thermostat and battery to fan. Keep in mind, when making these connections, you actually wire up everything before connecting the solar panel to the charge controller. Do that last. I just listed it in that sequence for visual references. You can install fuses and shut off switches if you like, but probably not needed for such minimal power draw.

You are so amazing! Lots of thought involved. I'm sure it feels awesome to have your plans prove right!

[@jamespatterson1433]

Cold air coming up the hole in the floor is only happing because hot air is going up and out the holes in the gables. Its a good thing, I wouldn't totally plug it.

[@rufusTfirefly67]

If your seals end up being a weak point due to the heat, you could potentially replace them with silicone seals which would be more heat resistant.

[@dt9094]

I like your thinking. Great job

[@twohats8462]

Made a still/water heater/oven/grill...worked great

[@forresta65]

When your spending a weekend at the cabin when it is enclosed you can use it so you can stay over night.

[@shredct3118]

Thank you for taking the time to explain what you have done. I'm going to try this for my small shop . I'll share my results with you on IG.👍🔥🔥 Thanks again my friend.

[@bradleyschneider3871]

Yea that would work for your shop u might want to put 2 or 3 water tanks around the shop to have even heat.just saying

[@comucall]

Ingenious, Great video.

[@emelen123jamesula2]

Nice system, very good for a cabin

[@ZombieBitesAgain]

Nice job my fellow Canadian can't wait to see how the cabin will turn out once you get it done 😀

[@hueypilot1950]

Great prototype, 2nd generation (sand in lobster pot), I see many applications and variations. My next tweak might be a rocket stove or wood stove to improve efficiency and all night warmth. I have thought up similar systems but I don't have the talent and money to make them happen, especially the talent. As good as buddy heaters are, some form of external fire and heat transfer to the inside would be better for lots of campers. and would pump less moisture and products of combustion into the camper.

[@MrJahanzebharoon]

Man i was thinking about this idea from last 2 days and I'm very pleased to see that you implemented it in a very easy and practical manner.

[@heatherwatson8273]

When cooking on a fire like that I use tongs to pull a few pieces of wood away from the fire to cool down the temperature, just like you add more wood to increase the heat. You also have snow which you can use to put out half of the fire, not all of the fire just half.
