I hope this video was helpful and here are some key feedback comments so far: They may not allow delivery of kerosene without an 'approved' tank. Reversing the direction of the air blower mod may give better results to improve efficiency. The heater was held at customs because of poor instructions which could cause someone to use it dangerously. The heater itself is fine. I'm looking forward to hearing your other thoughts on the subject and any ideas for future videos. Here are some links but there is also more in the description.

Here's another idea for (supplimental) heating: did you know that composting is exothermic--i.e. produces heat? Up to 70C at times. It occurred to me that if you buried a car radiator (or two or three) in a compost pile--mostly wood waste, as that takes the longest to break down, but any proper ratio of 'greens' to 'browns' would do--and pumped water through it to a second radiator set up with a fan in your shop, that would offset at least some of the fuel you would need to burn. If you look up 'Jean Pain compost heating', you'll find a *LOT* of info on what it is all about, including how to harvest the methane that composting produces as yet another energy source. Cheers!

26:40 you can't talk about temperature in %, because the temperature scale is a relative scale, 0C is actually 273.15K. do the math again in K and you get another % value. or do it in F and get another %. so just never talk about % when you talk temperatures. its not applicable so its wrong. you should talk temperature difference instead in degrees.

When you run the exhaust through a radiator to super-cool it and pull more heat out of it the condensed liquid it produces has a very high probability of becoming acidic, so you may want to keep an eye on the radiator you've added for rusting out faster than expected.
@iplugnplay3366 4 місяці тому
Indeed, it is easier to heat a medium from low to high, to gradually heat it up, if you start at the hot side it heats up fast but then can't heat anymore because the air is already hotter than the exhaust. Also the flow needs to be higher than the flow of the exhaust, it would be fun to see the flows on that.

Just thought that I would mention the exhaust angle, if anybody is looking at harvesting the heat from it. Whether using water, air, sand or whatever medium to extract the heat from the exhaust (which is a great idea)….. the water vapour within the exhaust gases will always condense inside the exhaust pipe. Therefore, it’s best to keep the exhaust pipe at a continuous downward angle, so that the water can escape….. outside, ideally. Also, maybe have a look for a smooth pipe oppose to the ribbed one that comes as standard. If you used some stainless plumbing pipe and fittings….. it will last forever!! Thanks for the videos, Joshua. Always engaging, interesting, and love the humour 🤪.
@joshuadelisle 4 місяці тому

@cannaroe1213 4 місяці тому
In corrugated exhaust pipe at any angle there are always pockets for water to collect. It is constantly evaporating/vaporizing as more is condensing, in a process that turns gas to liquid to vapour in the exhaust. Even once shutdown, the pipe being 80°C will speed up evaporation of all of the carbonic acid, eventually. Its deliberately a large surface area/volume ratio. If you use a smooth pipe you do maximize the output of carbonic acid, but to paraphrase Dr Ian Malcolm "we were so busy asking whether or not we could, we forgot to ask ourselves if we should"
@dangeary2134 4 місяці тому
I wouldn’t let that water get outside, it’s going to be contaminated. Make the exhaust, going down, and if you do use the barrel for hot water, have the pipe continue downward, then up and out. At the bottom of the dip, put a tee pointed down to a small tank, with the opening of the pipe near the bottom. Put a float valve into the tank, and place it so there is always a few centimeters of water in the tank. That will keep exhaust from escaping through the tank. The float should activate a small pump that would go to the sewer when it gets full enough. The wastewater treatment plant can handle that stuff a whole lot better than your lawn or anywhere else that stuff would run, such as a stream or river. If you want to extract more heat into the water in your tank, put a finned pipe inside the tank for better heat extraction. BYW, put a vent on your heat tube close to the burner end, and turn the fan around to blow the air in, rather than pulling it out. It’ll make for better heat coming out of the heat tube, and it won’t be warming the exhaust pipe on its way out. It’s rather like the way modern furnaces work, by getting the most heat out of whatever you are pulling heat from.

A massive safety aspect you missed on the Hicalory heater. The power adapter mains lead may not have a fuse, but it does have a plug where the Earth pin is - wrongly - sheathed. Chinese factories do get confused about the function of the Earth in a mains plug. The Earth pin should be the first pin to make contact and the last to disconnect: hence it being the longest pin. That way you are protected for the longest time. Similarly, the Earth wire inside the plug should have the longest length of 'slack' wire so that if the wires work loose, the Earth will still be connected - and the user protected - even if Live and Neutral wires break free. It's the Earth pin that pushes the safety shutters aside in the mains socket, so that the Earth pin connects first and disconnects last to the Earth contacts immediately inside the socket. Whereas the Live and Neutral contacts are recessed deeper inside. With the Earth pin sheathed, the Earth will be insulated as the Earth pin cannot touch the socket's Earth contacts - the device will not be Earthed... Perhaps you might like to notify H M Customs and the retailer about the seriousness of that anomaly.

It isn't that they should make it plastic, it's having the isolation on a metal Earth pin in the first place. This device is metal cased and therefore needs an Eatth. The problem is that they are confused why there is shielding there in the first place.

I'm off-grid here in Finland. I provide my own power: in summer this is easy, solar. In winter, heating is done with wood - with a very efficient wood gasification boiler. Power in winter is generated with a diesel generator running on biodiesel I make in summer from waste vegetable oil. Using wood is very common here, especially in the countryside. It's the cheapest fuel for this, and readily available everywhere. I produce mine (cut and split with electrical tools when I have excess solar power) from my own forest, turning a tree farm into a diverse forest.

You should have that little fan blowing in instead of sucking out. When trying to exchange heat in that way, it's best to have the two medias (exhaust gas, and cooling air) going opposite directions. Also, not sure if you have already or not, but make sure your long run of exhaust has a slope out so the moisture condensing will run out instead of staying in there.
@Styrola 4 місяці тому
And blowing the air instead of sucking it will create turbulent flow instead of linear which should be more effective.

@josholin31 4 місяці тому
Carbon monoxide floats in air while carbon dioxide sinks. Idk if sloping it in either direction is safe... but then again, it is forced air. if I had to choose though, I'd slope it downwards from the source. Then carbon dioxide would be the main gas to worry about coming back in (especially after turning it off.) And at least that gas is detectable even without assistance. - but then we'd have to make sure there is always a fan cooling the exhaust. The slope would make heat rise towards the heater.

That fan is a very good way of extracting heat from that pipe. The only thing I can think of to get just a little more heat from that pipe is with heat exchange fins around the pipe to have a higher surface-to-air ratio. Just make sure that the fins run with the air flow and not parallel. You might need an extra fan doing that to get the needed airflow.
@dead2thewind 4 місяці тому
If you didn't already; counter flowing the fluid over the exhaust allows for more efficient extraction. Allow the colder side of the exhaust to warm the air and have the air flow over hotter and hotter sections of the exhaust, so the temperature difference is high across the box section.

If you want to extract even more energy out of this system, try putting insulation between the exhaust pipe and the wall. Since the wall goes to the outside, it is going to be cooler and will essentially be a heat sink. By insulating it you have more trapped thermal energy to siphon off which will increase your efficiency specifically on the draw of the exhaust.
@akulkis 4 місяці тому
Insulate the wall, not the exhaust pipe. Better solution is to add enough pipe onto the exhaust pipe to create a heat exchanger so as to extract as much heat as possible (i.e. exhaust reaches close to room temperature) BEFORE it goes into the wall. Or in other words, run the exhaust pipe into a radiator, which then has a pipe on the outlet going to the wall and then outside.

Hi, you can increase the efficiency of the ducted fan solution by reversing the flow of the fan. I.e. push colder air in at the point furthest away from the heater. This keeps a more constant temperature differential between the air and the exhaust pipe temperature and thus better heat exchange.
@ColinWoodpeckerUK 4 місяці тому
Yes, I thought the same. (Just edited this because I reread what I'd written and realised I was previously talking gibberish!) But, It's called the principle of contra flow. When you want two fluids to exchange the most heat in the most efficient way, put the cold inlet of secondary fluid (could be liquid or gas) into the heat exchanger at the cold end of the primary fluid. That way the cooler primary can still give up heat to the colder secondary) The computer fan wouldn't enjoy being so close to the 200•C end of the Exhaust pipe either, so reversing the polarity of the fan and blowing air in rather than moving it to the other end of your shroud and sucking the air out will reverse the flow like you say. That's the way forward... 🤔

great work! If your priority is immediate heat over lingering heat, all you need is a longer exhaust pipe to the point where the outflow is room temperature. For varying situations, you could have the end bit in sections with valves for multiple exhaust lengths to switch between. Insulating your walls and crevices will do more than sealing in exhaust heat with sand on water, I'd guestimate.

Oh, what is the outlet arrangement? If you haven't made another opening, make one at the end close to the burner. Make it quite small, so there is a positive pressure in the duct. It probably won't make a practical difference, but it might reduce the chance of exhaust leaks into your shed, because the pressure gradient will be slightly harder to overcome than just going out the silencer... With a computer fan the difference probably isn't enough to have a big impact though. But meh. Why not.

Another variation on the forced air through the shroud technique would be to make the shroud slightly larger than the diameter of the exhaust pipe and use the fan to PUSH the air through. This would increase the velocity of the air around the pipe and therefore give a larger temp differential, and spare the fan from the hottest air. I'm definitely getting one of these systems when I buy my house.
@wouterke9871 4 місяці тому
Larger temperature differential means higher efficiency where the transfer of heated air occurs.
@BirgitWallmuller 4 місяці тому
I had the same idea pushing the air should be the better option. But my main reasoning is different - it is the heat differential. If you push the air(or suck out on the heater side), then the colder ambient air meets the already cooled exhaust pipe there and while it travels to the heater side it warms up on an increasingly hot exhaust pipe. That means on an sufficiently long exhaust pipe the exhaust gas temperature can reach almost ambient temperature inside. A greater airflow or increased surface area on the exhaust pipe would improve too (or reach that result earlier). Probably taking the idea from the output pipe - a pipe to take in the air close from the floor, which should be cooler should be an improvement too,

Just a note on efficiency. If you try to recover too much heat from the exhaust you will drop the temperature below the dew point of the fuel. This will cause a build up of soot like deposits in the exhaust. In time this build up will reduce the ability of the unit to clear the exhaust resulting in poor combustion within the burner and a serious reduction in efficiency. So, to be efficient and safe check the dew point temperature of the fuel you use and allow an extra 10% margin and this figure should be the temperature of the flue gas leaving the exhaust pipe. Your system will then be operating at 100% design efficiency.
@kevingossage5304 4 місяці тому
I haven’t read all the comments but the most effective way to recover heat from airflow (exhaust) is for the outside to be finned like an air cooled motor.

Sand battery benefits come from the ability to be heated up to hundreds of degrees of C without building up pressure or boiling. High temperature difference from the source to the storage -> high heat flow -> effective heat transfer from high temperature storage.

Just a side note. The sand battery would help maintain a longer heating period which should require less time overall to reach a better working temp on the next startup. Also the sand looked wet ! Dry sand is better which would be achieved with longer run times as the continued heat slowly removes all the moisture. The test should have really been over a couple of weeks and used sand that had been sieved / graded. As for using a radiator (yes that again LOL) The same thing but using a closed loop and small 12 volt pump to circulate the water. Water head should be taken into account based on the head flow of any pump. As an avid "upcycler" myself I use the exhaust from the house ran through a 6 inch sewer pipe just 2 foot under the ground across to my garage. Currently don't filter that air as there are enough air leaks to remove almost all the harmful effects to an acceptable level. Here in Canada I often see as low as minus 40 on some days in winter which had made the garage unusable. Now I have enough heat to be able to use it most days for a period of time. It also helps prevent such as latex paints from going off due to extreme cold. Yes I need to improve it so this vid gave me some more ideas.

As a suggestion, you could replace the exhaust pipe with a finned tube radiator. Due to the increased surface area you will extract much more heat. Also put the exhaust at an angle to make sure that any water can drip out and doesn't collect in the pipe when extracting the heat. BTW, I like the idea with the fan, but how about replacing it with a 230-volt fan? They are more powerful and, considering the losses in the power supply, probably more efficient than a 12-volt one.

DC Fans are much more efficient for same air flow, can run off battery in the event of a power failure and are highly controllable compared to most AC or shaded pole fans. You don't need super powerful fans, you need fans that can provide the airflow. There is a difference between airflow and "powerful". An 80% efficient power supply, which is well and truly within possibility even for cheap chineseum, will still be more efficient than a shaded pole AC fan.

But if everyone had wood burners then the wood you collect for free would be very scarce and you would find the Dheads deforesting our own woods just to burn, it would be like the good old smog days. I live near north wales and lots of people have log fires. I agree the smell is nice. But if you took your air meter to a town I will bet that the air quality is rubbish. We all need to breathe clean-ish air. The thing now with mass burning of wood is that they employ the same principles that the catalytic converters use in cars. They harness the gasses into a chamber and further gets cleaned before it gets exhausted into the air. Homes however don't do this it goes straight into the air. Nuclear is they way to go and even fission. As an Engineer myself, I have thought over the years about heating conservation. The answer is the Sun. Everything gets heated via infrared , We need to find a way of making materials like cladding,roof tiles, tarmac etc that can harness it, then we need to turn that heat into potential or even chemical energy and then further harness this into a super conductor or battery and store it. Every house should have a battery a bit like water harvesting. The world is filled with untapped energy, the waves, the wind and the sun. It's all about thinking outside the box. Imagine a new road coating that could harness the light, the world is full of them and guess what? They all point upwards. Roof tiles that do the same thing.

Don't forget usually in coldet temperatures the humidity is also lower. I'm not talking about the rain seasons like late spring or early fall. Just saying pretty much winter. The heat travels to colder areas. As the water evaporates if it is inside the heat will be there plus maybe needed humidity.

@Splatpope 4 місяці тому
that's probably why they mentioned pumping steam through the sand, I would guess that the water/steam stays somewhat pressurized in a closed loop, negating the problems of evaporation (it can be condensed at some other point and the latent heat recuperated through a heat exchanged or something, heat pump style)

I like a few of the ideas that have popped up in the comments. Particularly reversing the fan. I would be wary of making a more efficient radiator unless you have a way of stopping deposits from forming inside the exhaust section when the temperature is lowered too far. Also, I see that a sand battery would be good in an area where you need continued heating when the heater is off e.g. sleeping areas. So you can turn off the engine to sleep in the quiet, while retaining the continued heating ability of the sand. An air or liquid radiator is ideal when you need to use an area, and then leave e.g. a workspace, like a converted garage. As much of the heat as possible is used to heat the air while you are there. Then when you leave the area, there is no residual heat stored in the sand that would be wasted while you are not there.

Try adding larger bore lengths of pipe to the exhaust, only growing in size as you go a long the length. This will slow down the exhaust gas and give it more surface area to transfer the heat better. You can also use clean edged stuff to make the flow more laminar and help exhaust condensation flow out. I was hoping you were going to turn the oil drum into a sand battery. Ya big tease... Definitely looking forward to a video on used cooking oil filtering as I'm doing that myself. Used coffee grounds and coffee filters are my current secret sauce (along with sand).

The one issue with this is that you GREATLY reduce the amount of exhaust gasses that come into contact with the side walls of the exhaust gas exponentially as you make the pipe wider. That actually reduced the amount of thermal transfer you get.

Sand battery on the hot air output (not the exhaust) is a shout, just a case of working out what bore to make the coil through the sand to avoid excess back pressure.
@RushCampAndPrep 4 місяці тому
@@Jonathan_Doe_ a sand battery on the output side would completely negate the point of him using a decent heater. He mentioned in the video that he has a wood heater, but he uses the diesel heater to heat up his shop quickly and have it warm when he gets out there . There . If you added a thermal battery to the outlet side that would increase the amount of time that it takes to heat up the shop in the morning.

Completely agree about using wood burners, I've lived in boats, benders & on the road in various motors, always had a burner. However, you do need to be near a wood, getting enough wood for a day takes a lot of time & energy. Most folk however buy the stuff, & it ain't cheap, about £100+ for a "ton" bag. There are ways top get cheap wood, again, it takes time. Thanks for this video & all your time & effort.

@jackykoning 4 місяці тому
One thing that sadly might be wrong here is the direction of your fan. You moved the air from hot to cold which could result in the cold side getting hotter and the hot side getting colder. You want a gradual increase in temperature so move the colder air over the colder area and gradually increase it by moving to a hotter and hotter area. This greatly increases efficiency. In chemistry you always have the cold water at the bottom of the condenser and the water flows from bottom to top where the hot product comes from the top to the bottom. My teacher hammered that in. That said its air... air isn't the best way to remove or add heat. You need a massive amount of surface area. For example my radiator at home I have 7 2000 rpm 14CM fans running full speed when the temperature rises above 25 celcius. It takes 15 minutes for it to cool down the water below 25c when its just sitting there so after I turned off the knob. That is really inefficient and I am in need of a better solution. Perhaps just reducing the flow rate.

try having the air cooling in a counter flow configuration. you should extract more heat that way. all of the most efficient heat exchange systems use counter flow in one way or another edit: seems im not the only person to suggest this 😅

@zerumsum1640 4 місяці тому
@@joshuadelisle Here's the reason behind counterflow being more effective: When heating or cooling something, the transfer of heat depends on the temperature difference. The more heat in the heat source, the quicker it will flow to what is being heated. think of it like a trough with a dam in the middle. the dam is the ambient temperature, and the water level being held back is the heat source temperature. the higher the water is above the top of the dam, the more water can flow. by having the exhaust going one way and having the exhaust cooling (heat exchanger air, whatever ya wanna call it) going backwards relevant to that, you're putting the coldest exchanger air at the coldest part of the heat source. This increases the temperature difference between the two so you'll pull more heat out of the cold end. since the temperature gradient of the exhaust pipe gets hotter the closer you get to the heat source, you may be decreasing the gradient at the hot end a little, but you more than make up for it by increasing the difference at the cold end. another thing that can help this is by piping the intake end of the heat exchanger so it pulls air from near the floor rather than 1/3 up the wall. air by the floor will be the coldest after all. In fact, you may even be able to get away without the fan if you did so as the warmer air will rise and pull colder air in so long as you have enough of a height difference between the in and out (less noisy, no need to power it, etc.). other things that can help this: using a high temp thermal glue to couple some strips of sheet metal to the exhaust tube, wrapping the exhaust tube with a bunch of wire with 2-3 inch ends sticking off it can have a similar effect. surface area is key to improving heat transfer as the air has to contact the hot bit to pull heat out. One more thing i just thought of is to try coiling the exhaust tube so that you essentially make a coil spring shape out of it with a few inches between the coils. I don't know if this would improve efficiency, but it could allow you to fit the same (or more) exhaust tube in a heat exhanger half the length.
@ppokorny99 4 місяці тому
Given the condensation problems with the exhaust, I think coils would trap condensate. But a slight decline in the run of the exhaust would likely be good for both issues. Make the outlet lower than the heater so the condensate runs downhill and the air in the tunnel will naturally flow uphill.
@joshuadelisle 4 місяці тому
@@zerumsum1640 excellent information. Thank you. Cheers J
@zerumsum1640 4 місяці тому
@@ppokorny99 Rotate it 90 degrees so the outlet is on the bottom and the inlet on the top for the exhaust tube. Hell, in a vertical configuration it'll pull its own draft so you won't need a fan. so long as the hot end of the exhaust is the top you've probably got the best way to set this up. Depending on how crafty you want to be with it, i can see an exhaust line coiled up in a piece of round air duct with a cap on both ends. have the coil offset from the walls, and a few tubes running the length of it inside the middle of the coil. fill the deadspace with sand or water and you have a heat battery. I think the main flaw of the sand test in this video is that the whole thing is so long. you're not concentrating the heat in the sand, you're just using the sand as a mid stage between the room and the pipe. by packing it all into a smaller space, and swapping to a vertical setup, it'll allow the system to create a draft to more effectively dump that heat back into the room when the heater itself isn't running. After all, in the end we're trying to keep the heat in the room. Heat batteries improve efficiency by keeping the heat around and releasing it over time, leading to the heater needing to be run less. I bet with the right setup reclaiming the exhaust heat like this would probably improve the overall system efficiency by quite a bit.
