The water in your exhaust is probably not from a leak in the line, but from condensing water of the exhaust fumes. Burning hydrocarbons creates CO2 and H20. Cooling the exhaust in the bucket condenses the water vapours from the exhaust.

PS The viscosity of Diesel is 35 Redwood, Kerosene is 28, but the waste oil is likely to be c. 200 or so. If you added a tiny 5W 12v bulb to preheat the waste oil thereby lowering its viscosity, you most likely would eliminate the unburnt fuel (smoke) withiut having to add the Kerosene to your waste oil.

I love the content on this channel!!!! I bought one of these heaters a few years ago and still haven't unboxed it. Believe it or not... I was a Captain in the U.S. Army back in the mid 2000's and I was burning used vegetable oil in my 2500 Dodge Diesel truck!! I would gather the used veg oil from the dining facilities on post and take it home and strain it through a window screen into a 30 gallon trash can. Then I had two pumps that would pull the oil from the bottom of the trash can at the petcock. The pumps would run the oil through two different size micron filters two get the particulate down to 5 micron. Then straight into the fuel tank on the truck. Before the oil leaving the trash can I had to include 10% gasoline, 1 qt of diesel clean, and about an once of a special additive that I bought from a dealer here on youtube. It worked pretty well but you had to leave 1/3 tank of diesel in the truck or you would clog up your fuel filters on the engine. Anyway, it worked until diesel prices dropped after Hurricane Katrina. What I found interesting was that during this time Diesel prices were near $5.00 a gallon but I would fill up on Kerosene at the pump, when I could find it, for about $1.67 a gallon. Kerosene is actually what is considered #1 diesel, a cleaner version of diesel.

Used cooking oil is easy to clean. You need an inverted barrel with the bottom cut off. Fit a water heating element in the (new) bottom side so it runs parallel to the bottom of the barrel. Fit a petcock into the bottom to drain the water. The screw cap will allow crud to be washed out. Fit another petcock 25% up from the bottom. Fill the barrel with water to below the upper petcock and top up with used cooking oil. Now heat the water and boil it for an hour. The steam will literally wash the oil. You can drain the (now clean) oil via the side petcock. Drain the dirty water via the bottom petcock and barrel bung. The small amount of trapped oils stays in the barrel and gets added to the next boil wash. A commercial kitchen water boiler will do the same job for smaller batches.

Idea: your waste heat exhaust could be modified by using a partially water filled rain gutter deep enough to encompass the exhaust tube but the tube needs to run downhill to allow any condensation accumulating a place to drain and run outside. In the US, that usually means 0.25 inches per foot drop. Next idea: use copper water pipe so you can braze or solder the fittings for a leak free path. The inside of the copper is smooth so accumulating dirty condensation is minimal and it leaves quickly. The biggest downside I see is keeping the water filled gutter from freezing if your climate gets that cool.

I like the way you used the exhaust run inside to maximize efficiency. I will probably do the same but put a slight downward slope on the exhaust pipe to allow any condensate to run out. I may even duct a small 12V fan behind the pipe to get a bit of a forced air effect off the exhaust pipe. I plan to use a battery with solar to run the system regardless how cheap using a power supply appears to be, I like the idea of the system being 100% off grid in the event of a power failure. I have a lot to do in preparation for my 9M x 12M pole barn before this system would provide any real benefit. Insulation is my first step and I will probably require two for these units on opposing walls. Thank you for taking the time to make this video. Very informative.

Great job, I taught bio-diesel at the local college, and drove coast to coast across the United States, Labor Day weekend (5 Days) in 2002 in A 2002 VW Beetle with 600 Miles at the start making 3036 miles west to east astoria oregon to Ocean city MD and of course back. I did similar experimenting and refining. Using a SS mesh filter, then two diesel filters I would ultra filter the waste oil from a chip (potato - thin slice). The last filter in the chain was a water block because I would store it and the oil is hydroscopic so when it cools down ( like when the temperature in the room cools at night) it actually draws moisture out of the air (oregon Pacific Northwest) it would settle on the bottom. I still have the car more than 240,000 Miles still run biodiesel ( available at the pump called B15) I have two other Vw’s with diesel engines 2006, 2014 and a gmc 6.5 Lt Turbo diesel 4x4 truck. Your doing it nearly exactly the same and never had any problems and change my car/truck fuel filters per mfg schedule, I would open the filter car fuel filters never found anything big or a lot ( no rust no contaminates) I had a lot of people tell me all kinds of things but never had any issues. When freezing temps expected just increased the diesel ratio to 50/50 then when it warmed back I would go. I maintain all the vehicles still on original glow plugs and injectors and high pressure pumps. But its likely how I drive, i am on the original clutch and the brake pads on the front were changed just because they were 18 years old, there was still more than half the available wear left. Enjoy the adventure. Mike

I had the same problem running mine on vegetable oil - I was using fresh sunflower oil rather than waste oil, and the exhaust was spitting out unburned fuel and a lot of smoke. It also stopped working after a few days, since there was so much soot deposits in the exhaust pipe that it partially blocked up. I solved the problem by mixing the vegetable oil about 50:50 with white spirit (I had a cheap supply of that), which thins it out nicely. When it comes to filtering your waste vegetable oil, I would recommend doing it in stages: Pass it through a wire mesh first (an old kitchen sieve would do the trick), which would take out any large-ish chunks of old batter or chip fragments. Then through a finer mesh, such as "OOO" grade steel wool. Finally through a paper or fabric filter, either coffee filters or a couple of layers of old tea towel. The first two stages should be fairly quick, and the bits they take out should mean the final stage doesn't clog up so much, so that should be quicker too. Another filtering tip: If you are going to mix your waste vegetable oil with some kerosene or diesel (or white spirit) anyway, you might as well mix this in before filtering it. This does mean a greater volume going through the filter of course, but the lower viscosity should speed up the filtering, so on balance it could well be faster overall.

@@steverpcbThat might be ok for a diesel engine because they inject the fuel into pre-heated compressed air, burning the metered spray of fuel all in one go. Diesel air heaters burn fuel with a continuous flame in air at ambient pressure, so are quite different. Both the viscosity and boiling point have to be low enough for the fuel spray to adequately vaporise, in order for complete combustion. Otherwise you get a lot of soot production which blocks up the exhaust outlet, and in the worst case you get ignition failure and unburned fuel spraying out of the exhaust. Also, the issue with diesel cars and vegetable oils isn't so much the engine itself - the first diesel engines to be designed actually burned peanut oil, and were only later on used with petroleum oils. The vegetable oil causes problems for the rubber gaskets in the fuel system, causing them to swell or even disintegrate. If you go through the fuel lines and injectors, replacing any rubber gaskets with viton (perfluoroelastomer) gaskets, it should be able to burn neat vegetable oil of any type without any problems at all.

Thanks. Great Video and testing. I burn Waste Veggie in my car and boat engines after letting it settle for a few weeks. Then I filter it through 5 micron bag filters. These bag filters are about 10 dollars in Canada. They are about 17 mm in diameter and 600 mm long. The oil goest through them pretty quickly. I just do it by gravity and a barrel of oil takes about an hour. I wash them with soap and hot water after every couple barrels. If the oil is particularly dirty from the restaurant or has a lot of bits in it, I put a a 400 mesh filter 'bag' inside the 5 micron filter bag and wash that as necessary. Works great, but you do have to let the oil settle for a few weeks first or it will plug up the filter bags pretty quickly - depending on how heavily used the oil is from the restaurant.

Excellent video!! Spent many years experimenting with WVO (Waste Vegetable Oil) for fueling diesel engines. I see a lot of parallels with this. For a diesel engine we achieved clean and efficient combustion by preheating the input oil to about 160F (71C). At this temperature the WVO thins out to a viscosity very close to diesel and atomizes much better. We did this by using waste heat from the engine with a fluid-to-fluid heat exchanger - engine coolant one side and WVO input line on the other. We also used a startup and shut down phase on regular fuel just like you already are and would only switchover to WVO once the engine was warmed up with the 160F preheat temp reached. You don't have engine coolant to use for preheat in your case, but you do have the exhaust heat. We experimented with that and found it to be too harsh / hot to use directly in a heat exchanger with the oil - it would polymerize and plug up after a while. But since you plan to already make a hot water heater with the exhaust, you could very easily use your hot water output as an input to preheat your oil input to the burner! This video is re-sparking my interest and I may have to add some similar experiments to my channel!

The effects were impressive, as it halved the time it took to heat the bungalow. In addition, the heaters remote temp sensor reduced the heaters pump speed as the room got warmer. The heater was mounted outside.

Hi Geoff. Living in Spain myself I’m very much interested in your experience with this heater for your bungalow. I like your idea of rerouting the hot air output back into the air intake but not certain if you Jean the hit air output (in full or in part) or the exhaust line. Can you please explain? We live in a bungalow which I insulated very well but our heating is still with inverters running partially on EV panels, partially on the grid (Iberdrola). I would like to use this air to air heating for the days / hours without sunshine… so in winter and at night. Can you indicate the efficiency of the heater in your bungalow and if possible, can we get in touch? We live on the Costa Blanca. Thanks. Marc

Ideally, your exhaust would be roughly the same temperature as the air temperature in space you're heating. You could put a pipe around your exhaust and blow room air through the gap created in the direction against the flow of the exhaust. Counterflow heat exchangers can achieve the optimum of ambient temperature exhaust temperature.

How about a coaxial heat exchanger? Run the exhaust tube inside a larger metal tube, which is used as the air intake (or at least part of it). This would mean that the incoming air is preheated which should improve efficiency. It could also be used to bring fresh air in from outside which would give the building a slight positive pressure.

I see someone purposely building one to fit into a fireplace for homes built prior to 1980’s . I bought one for my Macgregor M and use in the shop . I ended up running an exhaust pipe through the wall then up a down pipe from my gutter to get the exhaust up to roof height of my house so not to suck it back into the garage or annoy my neighbors. My point is these are amazingly cheap to run so trying to extract every btu seems like rubbing two pennies together. Clean burning equals efficiency so if you try to burn shit it will plug up and not burn clean or just fail completely.Your exhaust pipe is the most important bit for keeping it clean burning and Avoiding CARBON MONOXIDE! These heaters come with a small silencer. It is not air/exhaust tight at all and does act as a condensation trap which is good but never inside where you are breathing the same air. So if you buy one of these you must have a carbon monoxide detector. I love mine but also got a small electrical heater that burns 50 to 70 amps @ 12 volts with a tiny fan to maintain a nice temperature after heating with the diesel . Ok cheers and prayers for peace on earth !

I think you should not use paper element filters for diesel or kerosene unless specifically designed for it. Normally fine wire screens are used for diesel if you check at your auto parts dealer. The common cheap small paper element filters are for Petrol. Apparently the paper element eventually goes “soggy” in diesel and deteriorates. As it does so, it can pass along the fuel line and cause clogging/damage further on which can be difficult and expensive to fix in a Diesel engine.

@leifhietala807411 ай бұрын
The long horizontal run of the exhaust is excellent! The draft blower generates sufficient mass flow to carry along any condensed water to the exit and spit it out the end, outside the building. For maximum efficiency, double or even triple it. You might need to install a larger diameter exhaust pipe to keep the static flow resistance from becoming too much. Another length or two of exhaust pipe, below the first one, doubles or triples your heat exchange area to harvest more heat out of the exhaust. Make sure the exhaust duct is always sloped downward - it doesn't need to be much - will keep the water that condenses out of the exhaust gases flowing toward the exit.

If he adds more pipe below the existing exhaust, then he will have to cut a new larger hole in the wall. Add the additional exhaust above and then redirect the first cm's coming out of the burner to the top of the new manifold, the exhaust is so hot there that no condensation is taking place at that point, only further down the manifold where it starts to cool down. And yes, all sloped downwards and where it starts getting hand hot, go to a smooth pipe for better air and moisture flow. Keep the muffler and exhaust outside also facing downwards

If I'm not mistaken the manual says to keep the exhaust pipe to a maximum of 1 meter length. I believe it says this because any longer and the exhaust becomes a restriction leading to rich burn mixtures. If I were using a long exhaust like in the video I think I would use a much larger diameter pipe eg have the stock exhaust for a short a distance as possible and then step up to say a 3inch pipe. Run that 3 inch pipe indoors for as long a distance as possible and then vent outside. In addition to afrs staying correct, the exhaust gas will be slowed down massively (without causing a restriction) giving the exhaust gases more time to lose their heat inside the room.

I had the pump turned up to the highest setting and it put out an impressive amount of heat burning red diesel but there was an distinct smell of hot or burning plastic... I never found evidence of any melted of burnt plastic but I turned the pump down and the smell diminished greatly. Yesterday I drained the oil from my diesel van engine so I will be mixing that used oil in with the diesel fuel at what I judge to be about 25% initially... aiming for 50% eventually. My unit is outside. Only the battery, the control, and the heat tube is inside. You could put a small 12v PC type fan on your exhaust pipe to push that heat out into the room.

This runs the full length of the greenhouse and as it exits it is still too hot to put your hand on it without getting burned, however it runs much cleaner. The point being the soot build up you experienced may be due to exhaust restriction rather than the fuel. It might be worth experimenting with say a length of scaffold tubing it's easy enough to fabricate a connection with the gear you have.

For a heat exchanger run the exhaust through a pipe filled with sand. (1kg sand heated to 40c will take @ 5.5 hrs to drop down to 20c.)

10/10 for a great video I run mine in our heating oil and, like you recommended, use a small 12v good condition deep cycle 22 ahc battery with a trickle charge. The battery has the umff to get it all started, the trickle charger keeps it all going and recharges the battery back up.

Another thing I did during the fall here was to service it. Lots of films on YT showing that. I also bought "everything" I'd need to maintain, repair or replace. Like a spare glow plug and 2 tools pump, the gaskets, and of course a bag of the atomisers that I replace. That way IF something goes wrong in winter or during servicing, I can deal with it directly. I learned a lot if stuff about heating through this project.

Hi Joshua, first of all, congrats for your videos, I'm a big fan of your metal working videos and experiments. Regarding this topic, I would recommend you to get an EGR cooler (from a diesel car, to cool the exhaust before reentering to the combustion chamber) that way you will get a propper made gas to water heat exchanger. Thanks for your effort!

Waste veg oil apparently soots these up quicker, but you can strip it down and clean, and buy the mesh injector in packs of ten. To recycle the used cooking oil quicker there's a video whereby they put gelatine powder or something like that and it drags all the burned impure waste to the bottom of container and then filter. Supposed to be the quickest way to do it.

Ummmm, Josh, energy is measured in Joules (1 Watt second, although more frequently Kilojoules) or BTU (1055 joules), both of which can be converted by scaling them into kilowatt-hours. Kilowatts are a measure of power, not energy. So a heater that runs at a power output of 8 kilowatts will produce 8 kilowatt-hours of heat in 1 hour. 8 kilowatt-hours is 28800 kilojoules, or about 27300 BTU

My Good Man...I just found your vids today...love the reports on the oil burners ! I have a comment...it is about burning kerosene as opposed to diesel. I have read / heard that kerosene does not have the lubrication properties of diesel. This may be why you noticed a quieter sound decibel difference when switching from starting with kero, then switching to veg-oil. I have also read / heard that using kerosene will shorten the life of the pump because of lack of lubrication....because the pump is a piston...metal on metal piston. Just an observation. Absolutely love this stuff !!!

Thank you so much. Kerosene is designed specifically for heating. I'm making another video just now on the same heater as a kind of 12 month review. If the pump does fail they are only £15 to. Replace. I buy kerosene at £0.60 per litre so as you can imagine I'm saving a lot of money even if I have to buy a new pump every year. Cheers J

Good video- 1-historically you were correct in stating that a kWh of electricity costs a certain price and that they directly correspond. However this is no longer true with the new tariffs available. Its now possible at certain times to import electricity at night for 7.5 p per kWh or Zero p per kwh and or even get paid to import it! if you have a battery , you can even store electricity at these rates. 2 - how much have you allowed in the cost calculations for fuel etc used in picking up the waste oil? 3 Thermally one is better off bringing in cold air from the outside as cold air has more oxygen molecules per unit volume due to its higher density, rather than burning already heated air internally and then exhausting that already heated air. Really enjoyed the video - thank you

I enjoyed this video a lot, quite inspiring. I plan to augment the exhaust heat recovery design further with a DIY heat exchanger and combine this with an air source heat pump. To maximise heat recovery and efficiency, I will split my exhaust into 2 using 3/4" BSP 3 way cast iron female tee (3/4" bsp measures 1" inside), then slip a dozen copper coated scourers around outside of each tube, encase the whole thing in a metal duct and use a separate air input to be heated by the exhaust and feed the warmed air into an air source heat pump. The heated air will enter the cold side of the heat pump and wont be used for the clean air input, [for safety] just to ensure any exhaust gas leakage does not enter indoors. Running the oil heater on minimum Hz, I hope to be able to a) recover the most heat possible from the oil heater and b) be run the heat pump in a temperature range [in winter] where it works most effectively. Hopefully will produce a lot of heat at minimum £/KWh ;)

you should try running the exhaust through a normal water radiator. With the inlet in the top and exhaust out the bottom, so moisture can drain out with the exhaust.

Just a comment on units. The scientific unit of energy is the Joule (J). Power is the rate at which energy is produced or provided, that is Joules per second; 1 Joule per second we call a Watt (W). A kilowatt (kW) is 1000 Watts. Note Watts and kilowatts are units of power, not energy. Power x Time = Energy. So the commonly used unit of energy (apart from the Joule) is the kilowatt hour (kWh). Electrical energy is sold in kilowatt hours, not kilowatts!

Great stuff! Worth watching (&subscribing)... Saved my frying oil(for making oliebollen) and wanted it to mix it in with regular diesel and also the latter to be replaced by kerosene. When running your diesel car on veg oil, it was advised to just mix a little methanol in it as the viscosity is lower which could create starting problems. I would just run with 'blended' fuels. It looks we are going back to the old times, making our own fuel to stay independent! It was also the reason as why mr Diesel invented the diesel engine (only rich people could afford patrol cars). The whole reason why governments want to get us electric, to take our liberties. Anyway, great upload, looking forward to your next one!

Wrapping a coil of copper and then insulation around the exhaust would be far safer. Work on that hot water rises to avoid pumping it if you can, also get a pressure vessel that u can pressurise with the compressor to force the oil through to filter it. Perhaps modify a beer keg or an old compressor tank etc. also does your backyard smell like a chippy now? Lol
