[@warriorandzena]

Like @LowAmbitions I too am installing an "8kw" in my attic or actually void area, where the ducted aircon is and letting the fan sucking the hot air and blow it around the house. This is in Brisbane Australia, and I think it's possible to keep some rooms warm like 22 degrees, mind you the outdoor temp in winter goes to only -1 or -2 and day temp between 18 and 25. The area will be around 114 m2. I'm planning on using a bigger diameter aluminium pipe 2.5 meter long encapsulated in a bigger shorter open ended pipe, enclosed near the heater, but with a flex pipe attached, joining into the aircon ducting. I've done some preliminary testing without using the exhaust heat, and I got 22 deg with outside around 8 deg. What I don't know is I need to have the diesel tank outside on the ground, which mean the pump needs to pump close to 3 meter vertical and 2.5 meter horizontal. Any comment is very welcome......

Sorry I missed your comment. This sounds very interesting. Not something I could depend on here in Canada, but very cool.

[@johncollinsgrove1750]

Directions in my heater basically showed that the corner with the glow plug needs to be up. But your notice of vent hole location is a good catch. Also for the high end wabstos there install directions also show the corner with glow plug needs to be upward. Facing up could possibly cause an issue tho. If it were to flame out or not completely buring fuel it could leak fuel through the main air inlet at the back of the burn tube and leak into the housing.

[@loweredexpectations4927]

Yeah, with the heater sitting upright (exhaust and inlet down) the fuel path is down at a slight angle. Ideally, you want a direct downward path between where the fuel comes in, and the main burn area. As long as there is some down slope from the fuel inlet to the burn area, there shouldn't be a problem. However, if you were to install the heater so that the fuel has to go uphill to get into the burn area, this is a problem.... this would mean that it needs to fill the glow plug area before running into the burn area. Not good.

[@thegrimreaper7777]

I agree, glow plug at the top, no matter which way you choose to orient it, that way, if your pump fails and allows fuel to drain into the heater unimpeded, any unburnt fuel pools at the dead end of the outer casing, then fills the gap (and the centre burn tube) until it reaches the level of the exhaust port, at which point it can escape down the exhaust. The other way up, unburnt fuel can escape through the air hole and into the motor area, which may not be ideal. Remember some people have these mounted inside dwellings and vehicles, All 'should' have the exhaust routed outside, so having fuel drain via the exhaust rather than into the shell of the heater is the preferred option.

[@loweredexpectations4927]

@@thegrimreaper7777 I do agree with this, but if your pump fails and you have more than a litre of fuel, your heater is going to overfill and it will still dump out.... man, that would be a nightmare ! haha.

You sound like you understand this well enough to tell me if my idea is crazy or not :) Heating an RV, 35’ long. I want to have a chamber of coolant that is pumped through a couple different heat exchangers (aka radiators) in various parts of the vehicle. Thinking of modifying a standard diesel heater to heat liquid instead of air. Either having the heater partially submerged in the coolant tank, or making a container that fits around part of it. I’d also have a water-water heat exchanger for heating hot water, and an electric heater in the tank, and have the tank connected to the engine’s coolant loop. The biggest benefit of this complex arrangement is that I could have much more control over the temperature of air heating different parts of the RV, rather than blowing very hot air for a bit, then nothing. Not sure if this is a crazy idea. Just curious about your off the cuff thoughts. :)

[@loweredexpectations4927]

I don't know that it is crazy, but I think it's unnecessary. You can purchase these units that are already set up to heat water. You can't get them from Vevor, but they are available on many websites. They cost a little more, but I believe they are well worth it. Other than that, I think it is a great idea. You may need a larger than expected pump to circulate the water, or a dedicated pump for each room / exchanger.

[@gf2e]

@@loweredexpectations4927 Thanks for the suggestions and reminder. I will look around more thoroughly. When I checked a year ago or so, I saw one or two water ones, but they were ~3x the price and had very few but mostly poor reviews. I will search again, because it would be much simpler. I’m still trying to figure out how best to bring the system up / figure out what I need. One of the two propane furnaces is still totally reliable, one is a bit flakey. I might add some temperature probes and try using a single radiator and see how much heat it puts out. Or, maybe just try using it at home. Except that my house has much better insulation than the RV so I don’t know if that would be helpful.

I did an actual video on it a few days ago, but it made a cameo in this video, haha.

[@thefirstmissinglink]

Been trying to find out energy consumption on the 12 volt end. Am off grid at a ranch in the mountains and am calculating what kind of solar/wind setup I will need. On the used motor oil, probably keeping the glow plug on to elevate the temperature to vaporize the oil since it is not under pressure being atomized. Maybe a lower setting for the glow plug after the start up so it doesn't burn out too fast. I would call this a passive system since the fuel is not under pressure. That's why it's so hard to use the oil.

[@loweredexpectations4927]

Once the these heaters are up and running, they pull between 30 and 50 watts, depending on heat setting. The fan pulls the majority of that power. When they are firing up and shutting down, the wattage goes up around 120 watts for about 2 minutes on start up and one minute or less, on shut down. The main two main issues with motor oil are 1. As you say, not enough heat to flash of properly, and the plug on would take care of that. However 2 is that heavy oils will always leave some crud behind. The glow plug area would become plugged up very quickly if the plug was kept on. The main cause of failure when burning motor oil is the build up inside of the main burn area leading to restriction of airflow.... Then things spiral out of control really quickly.

[@werner.x]

@thefirstmissinglink: As you are on a ranch, you don't really need a mobile heater solution. An oven should do. If you'd weld yourself a dedicated waste oil oven with a real chimney, you can get away with a small fan of 5 watt or less, depending on oven size and oil feed. Best would be a normal oil flow regulator instead of drip feed, but the ones suited for thick waste oil may be out of production. There once were sites explaining the modifications to a normal light oil oil regulator, but i didn't check, if they are still there. If nothing else works, drip feed always do, but the (highly recommended) safety feature N/C solenoid valve will be another battery drain. I think, you'll get plenty of building ideas if you look for "blue flame waste oil heater". Basically you have to build a normal oil fired oven, but with removable bottom plate (daily cleaning) and an electric fan. I haven't tried that, but you might get blue flame even without a fan - if the chimney works good and the oven is designed right.

[@thefirstmissinglink]

@@werner.x I should have given a better explanation, I am modifying my motorhome for off-grid use. I want to use the diesel heater but I needed to know the power consumption on the 12 volt side of things.

@@loweredexpectations4927 yeah that'll make sense with it being so dirty. I guess the only way to clean it up would be to do the same thing they do with biodiesel. I'll be eager to see what you come up with.

[@loweredexpectations4927]

@@werner.x This is true. If I were somewhere outside of the city, I would certainly be building something a little more substantial than what I currently have. I like the challenge of keeping it in a self contained package and being able to buy off the shelf parts, but there are other ways to keep warm. A good designed burner could run without any power in a emergency situation and then use a a few watts for combustion air and a few watts for circulation for everyday use. I highly suspect that a high efficiency wood stove with a few mods would burn very clean and not require any forced combustion air.

[@Moonlightshadow-lq4fr]

The problem using waste oil or even brand new oil is the stuff that is in it. Somehow they put metals in the stuff like magnesium zinc etc and that stuff simply don't like to vaporize, even with extreme heat there is always a certain amount of residue left after a decent burn which is why it makes it difficult to re-light after a run down. I don't think that cog looking thing is helping the burn with oil, sure it will with diesel but it is gagging for blocking up with oil. If the fuel were allowed to get to the tube and burn in there it should be much better, but again it will need very frequent cleaning and have to be run red hot to minimise any build up. It would be nice if the head unit could be pulled off instead of bolting on sort of a bayonet fitting so it could be removed with ease and quickly and a quick scrape of tube should sort it for the next burn. I am eagerly looking forward to your design and David's and I am sure you will get decent results as you tinker around but it is all amazing to me. :)

[@loweredexpectations4927]

For sure. I have a video last year where I burnt brand new oil to put an end to the argument that my oil was "too dirty" ... I did 30 videos on this topic last year with 4 months of testing. Heavy oil and additives are a problem, and always will be, so the only solution is to deal with the build up. I will be releasing a video soon talking about my actual plan for this mod, and what I expect... I do expect that it will have to be cleaned frequently.

Not all of the chambers are built the same, but from all of them that I have seen, you will likely end up with some diesel leaking out if you place the heater with the exhaust pointing up. There is a small flame initiation hole where the glow plug is installed, and the fuel will pool around the plug until it runs out the hole.

for alternative fuels... please before you get all fancy try 1. ) stainless steel screen/mesh of various opening sizes around the part of tube with slots. Length of this roll of screen mesh enough to protrude well into the burn chamber. idea being to add additional hot surfaces to atomize the oil via contact with additional hot screen mesh in both primary and secondary combustion areas. Might need diesel start to get added material good and hot. 2.) Little more complex (expermenting wise) would be experementing withing different type mesh/ and wicking gauze density (aka- differenttypes SS wool) in place of what is spot welded in there.

[@loweredexpectations4927]

I have some stainless mesh sent to me by a viewer, and used it in a few previous tests, last year, but of course, not in this configuration. The idea of this additional chamber is basically 3 things. 1. To have a spot after the main chamber that is very hot before adding any alternative fuels, so they flash off immediately 2. space for junk to build up without harming performance and a part that can be easily removed and cleaned out when it does get dirty. Mesh and wicks may add some benefit, but what I have found is that anything like that will collect all of the crud from waste oils, (ash / coke) and become useless pretty quickly... but that doesn't mean that I won't try it, haha.

Your "bolt on" waste oil upgrade part is a great idea! Sounds like a nice little side business in the making if it works! I'm very interested in this as I'm sure many others are as well! I think I heard you mention there is no heat output difference between a 5 kW and 2 kW heater? Does the 5 kW use more fuel? If it does then it must produce more heat, so I'm confused (I'm sure I have some understandings wrong)!

[@loweredexpectations4927]

I will be releasing a video talking about this in a little more detail... the goal for this set up is to be a maintenance extender. It may be a total fail, but my hope is, it will work engou to collect data on how much crud builds up based on oil volume consumed. I have some ideas on a self cleaning unit, but that will take considerable work, and I need to know how much crud before attempting to make something to clear it.

[@AtimatikArmy]

@loweredexpectations4927 Maybe it is not truly realistic to run 100 percent waste oil, but fifty percent might be more viable and that would still be a huge win.

[@loweredexpectations4927]

@@AtimatikArmy In the end, this seems to be a percentage game.... Meaning a litre of oil leaves behind (i'm making up the thumbers) 10 grams of ash. It takes about 2 hours to burn a litre.... SO, if you dilute it 50/50, you burn 2 litres of fuel before consuming 1 litre of oil, essentially doubling your run time.... however, you have still only burned 1 litre of oil... Make sense ? I have talked with boiler techs as well as waste oil burner techs and they do have some interesting thoughts about keeping the temp high at the oil flashpoint location, but not too high further down the line. The ash that does not burn will melt if hot enough, and when it does, it is more likely to build up, rather than flow out the exhaust I'm not sure if this is based on research or assumption, but I have heard it from a few different people.

@loweredexpectations4927 So it doesn't burn off the carbon like a hotter spark plug will burn off the carbon so it doesn't foul?

[@loweredexpectations4927]

@@AtimatikArmy Yes and no. Carbon will burn off pretty easily with a little heat and enough oxygen. What is left behind from heavy oils is not carbon, but other non burnable minerals. When you refine oil and turn it into diesel or kerosene, you remove these substances. Ultra low sulphur diesel is an example of this. Even regular diesel or airplane fuel still has quite a bit of sulphur, and this either builds up, or ends up being pumped into the air... So, in some cases they process the fuel further to remove more sulphur.

Awesome video! I have a diesel heater from Vevor too wrecked one trying to burn motor oil, bought a second one to just burn diesel and the other one I use for tests. It is essential for me to find an alternative source to warm my house. Electric, propane, or petroleum are just not affordable anymore. Red diesel is doable but on max it wont heat the caravan to a good temperature when it gets cold outside like 0 Celsius and below, from the Netherlands by the way. I checked al those videos on WMO and my verdict is it cannot be done with the actual setup of these heaters. I hope you can get some more insights in if we can adapt them that it will burn WMO maybe with some cleaning? Appreciate you and your videos hoping for more!!

[@werner.x]

There is something wrong with your heater setup. My caravan has 8m inside lengt with 1,95m roof height, 2,4 width inside, Insulation only 30mm (it's from 1982) - and the 5Kw heater keeps it quite cozy at lowest setting this winter in Lower Saxony - not far from you and almost sea level, the recently minus 8 °C required half power. Full power only required, when heating a completely frozen caravan. But with that low fuel consumption at lowest setting (1,2Hz) there's no need to let it cool down, if you're just away for the day. As the evening get's cooler and i'm just sitting, watching YT, i raise to 2 Hz and maybe 3Hz, when it's colder than minus 2° So - where does your heat go? My guess ist an open skylight. Open skylights draw ice cold air inside and your bottom area get's cold - no matter how much the heater is putting out.

[@loweredexpectations4927]

Thanks for your comment. I agree with Werner, if you are recirculating air, a 5kw heater should be able to keep a decent size caravan pretty warm. I used one to heat my 24x26 foot garage last year, and while it has better insulation, it also has 9 foot ceilings and a lot of air space... it was fine at -20C I suspect this mod, if it works at all, will extend time between cleaning, but will of course need cleaning.

I used to work for a junkyard that had a waste oil heater and that thing was huge and clogged up weekly… and it had three filters before the oil even got to the heater part. I don’t have much confidence in either of you being able to make waste oil work in one of these. Stick with diesel, it’s going to be cheaper in the long term, waste oil is close to being illegal to burn, I’m pretty confident that it already is in the UK… which is ironic considering they burn it to get rid of what’s left after they recycle it.

One more option about the direction of the mounting. Would it not maybe be better to have a slight angle pointing downwards about 30 degrees with the burn chamber pointing downward at an angle so the oil has to drip down the chamber and it wont clog up? I saw horizontal vertical on the side etc. but not at slight angles?

[@loweredexpectations4927]

Are you talking about in a stock burn chamber, or a modified design ? In the OEM chamber, there is a baffle before the burn tube. The fuel / oil will pool behind this baffle if angled, and if it builds up it will drip off the centre of the baffle ... I can't say for sure. This could help.

Great video and explanation. I have one question regarding the orientation of the heat. Since the fuel flows unrestricted into the burn chamber, when the heater is powered down, would fuel in the metal or plastic line seep or wick into the burn chamber if this line entered from directly above or at an elevation great than where it enters the burn chamber? I hope my question makes sense. Thanks again,

[@loweredexpectations4927]

I think I understand, and the answer is no... Just like when you place a straw into a glass of water and place your thumb over the end, if you lift the straw out of the water, the water will stay in the straw until your thumb is removed... in this case, the fuel pump is your thumb. The only way you will get a substantial amount of fuel flowing, after the pump stops, is if the pump fails, or of the fuel line breaks or is disconnected at the pump. Hope this makes sense.

Meaning, if you have a heater that is already running borderline high elevation, with a little inlet restriction and then you restrict the exhaust, that could be trouble.

The 8Kw heater probably only is "8Kw ready". I have seen larger oil pumps offered. The one we always get is the standard 22ml model. But then - i can ramp this 22ml pump from 1,2Hz to 5 Hz with my heaters and controllers in stock setting. If you let it buzz with 10 Hz and this doesn't overheat the magnet, fan speed ramped up accordingly, this 8Kw maybe get real even with the small pump.

The one that I ordered claims that it consumes .7L/h , so I will have to see if it has a larger fuel pump or just runs at higher hz... likely a larger pump. It should arrive next week. When it does, I'm going to pull it all apart before I fire it up... try to document the whole thing.

Where do you get your burn chambers from? Do you know the purpose of the internal mesh? I have a burn chamber cut apart kind of like yours and found replacment mesh for it on aliexpress but yours seem to work without it. is it for holding heat or kind of wicking?

[@loweredexpectations4927]

I have purchase one chamber from WIsh .. I believe, and the others from aliexpress. The mesh is basically the same as a wick. It spread the fuel out over a larger area instead of just pooling in one spot. This larger surface area exposes it to more air and helps it burn cleaner. Diesel flashes off very quickly at higher temperatures, so you may only notice issues during start up, before the chamber reaches temperature. If you have cut your chamber apart, you want to make sure that it is sealed up well. I use stainless steel rings and a hose clamp... If you do not do this, the diesel can drip out of the chamber before burning and burn in the exchanger or while going out the exhaust. This makes a lot more carbon monoxide and is less efficient.

I didn't mention it in the video, but if you look at the inspection camera view, in the end of the burn tube you can kinda see a few fingers in the slotted are that are larger (wider) ... The incoming combustion air is actually partly shielded so that it doesn't blow directly back into the glow plug hole.

I would think that the waste oil would have to be diluted with diesel to help stop the contamination of the burn chamber. Waste oil is full of stuff that likes to stick to everything. Your video was very educational as I have just picked up a 5 kw Vevor diesel heater to experiment with home heating.

[@Moonlightshadow-lq4fr]

Absolutely it needs to be diluted. I use 10% kerosene to my waste dirty oil, put it through a kitchen sieve to filter, I don't suffer with blockages in fuel pipe even inside the burn chamber which delighted me no end :) But it needs to be cleaned out every day really. It will burn again next day without cleaning but doesn't like it after a few hours. But that's my thing it's not a diesel heater, just what I found out over a few years the problems using oil.

[@loweredexpectations4927]

Thanks for the comment. I have a 30 part video series where I tried burning waste motor oil with all sorts of different fuels, diesel, alcohol, gasoline, varsol, DPF cleaner etc. In the end, WMO is heavy oil and will always leave ash behind. When you refine heavy oil and get diesel or kerosene, you remove the crud that would have been left behind, that is why they burn so clean Waste veg oil has glycerine, and that is what causes the problems with it. The only real solution is to make a heater that is easy to maintain, has more space for build up (before causing problems) or create something that is mechanically self cleaning. I would suggest to keep diesel, kerosene or light fuels in your heater... I twill work really great if you do that, haha.

[@loweredexpectations4927]

Thanks for your comment / input. I see you have some waste oil burner videos. I will give them a watch if I ever find the time. The issue with these little heaters is that they have very little volume, and any change to the geometry of the chamber can cause things to go way out of whack. A waste oil furnace / burner has a lot of advantages over the burn chambers on these things. I have tried diluting up to 70% diesel 20% waste oil and 10% gasoline, and my heater would run for less than 24H before issues.

[@Moonlightshadow-lq4fr]

I wonder if the exhaust isn't big enough for waste oil, because it has more mass and more energy than kerosene so it produces more gas?

Maybe I should ask this question to my doctor. 😅 An engineer measured the 8kW to be outputting only 4kW. Can't wait your test. Wouldn't a rocket stove of some sort is the most efficient way to burn waste oil? It wouldn't need any electricity. If you use or modify a diesel heater to burn waste oil, you still have to open it up and clean the carbon sooth built up daily?! If the flame initiation hole is very critical, I'm afraid I won't be able to mount it upside down, fan blowing downwards position because I plan to dip the heat exchanger in water in my water heating project. That's for later. I have a few questions for you regarding my air heater project with exhaust heat recovery. The exhaust outlet ID is 3/4" or ~19mm and OD is ~24.5mm and the ID of the exhaust pipe is 1" or ~24.5-25mm. If I install a 3/4" straight bulkhead fitting somewhere down the exhaust pipe to transition from inside of a heavy duty plastic bucket of water to outside, do you think it will "significantly" restrict the exhaust flow or should I use a 1" ID fitting? Then it will make it a bit more complicated, I mean I will have to use a 32mm-25mm silicone reducers as the OD of 1" bulkhead fitting will be 32mm. Any suggestion is very much appreciated. My last question is if I dip the stainless exhaust permanently in water, will it get rust, if so, after what period according to your experience? Thank you very much in advance for your answers. Have a nice weekend.

[@loweredexpectations4927]

Haha... yeah.. I looked at the plug afterwards and there was some sort of anomaly right where it broke... The plut itself is ceramic, and the metal threaded part has a crimp or 🤷‍♂️ something right in that spot. I wish you hadn't asked me about the ear canal, lol... of course I had to check... it's not pretty in there. To answer your question, this is not the idea tool for that job. I can see just enough to make me want to see more. Yes, I suspect most 8kw heaters only put out about 4.3kw based on fuel consumption. The heater that I got is actually a bigger unit, from what I understand. A rocket stove could work, but I believe the battle is this... Air flow is dependent on losing heat out the chimney. They are powered by convection current, so the amount of air coming in, is related to the amount of heat rising out of the chimney. If you dissipate the heat efficiently (don't lose it out the chimney) then your combustion air flow decreases and you are left with a dirty burn. This is why forced air is used on almost everything. However, if you aren't paying for the fuel, and you are willing to throw a lot of it away, then it could work with the right design. Fan blowing downwards shouldn't be affected by the placement of the initiation hole. I have not had success with running this way as the heater will flutter and flame out HOWEVER this may be because I wasn't using a chamber wick, as it had been removed. I have done a tiny bit of testing with my pipe, and I can say that 3 feet of extra pipe (about 5 feet in total) causes the CO levels to increase a little.... This leads be to believe that it will become a problem pretty quickly. 1" should be safe. The stainless exhaust won't runst, from what I can tell... If you keep it from getting to hot, it appears that it will last a long time... if you get it red hot repeatedly (like I have with mine) it will crack if bent or flexed... Ask how I know, haha.

You want a fight in the comments?!? I assume aboot the video...but I don't have a fight on that, you are much more educated than I on that. So how aboot this.... Wisconsin maple syrup is better than anything from Quebec. 🤪

[@Nordic_Mechanic]

Now that does it ! You have a mortal ennemi now ! Your lamp post syrup is no match to the fine Quebecois true white north syrup!

[@loweredexpectations4927]

Haha.. Thanks for the fight ! You're talking pure nonsense. "Wisconsin" more like "You Wishconsin" 🤣 I heard they buy Quebec maple syrup and cut it 50/50 with Ant Jamamias.

[@loweredexpectations4927]

Lol.... Wishconsin thinking that creosote is maple syrup !

[@ryanzanow8221]

@loweredexpectations4927 first off, STOP giving away the Wisconsin syrup secret!! How DARE you!😅

[@ryanzanow8221]

@loweredexpectations4927 secondly, it is not the creosote maple syrup you're thinking aboot, it's the creosote smoked venison that everyone is aboot around here, ya der hey! That said, we have yet to make a stove specifically dedicated to utilizing waste smoke from our heat source...that just seems WAY too Canadian for us down here, dontch ya know!

[@mnp3713]

i would pay 500euro for a heater that burn waste oil as easy as diesel.

[@loweredexpectations4927]

I think my mod is a long way from that.... "waste oil as easy as diesel" may be possible, but what I'm aiming at first is an extended cleaning interval mod. I do have a few ideas for making something that is .... self cleaning, we will call it, but that is a ways off.

[@gbear1005]

A hundred dollar one can do it easily. 40 percent very well filtered waste or veggie oil..50 percent new diesel /heating oil/kerosene/jet A, and 10 percent petrol. Run at least 1/2 to full throttle. Switch to straight diesel if you can't run at least 1/2 power and during any startup / shut down

​@@gbear1005 fake news

[@loweredexpectations4927]

​@@gbear1005 Please make a video showing this happening. There are lots of videos of people doing this and failing, so we would all like to know how your setup is different from all of those that have failed. I am curious to know where the glycerine goes that seems to cause everyone else problems. In biodiesel, this is "cracked" out using alcohol and lye and then the glycerine is removed before burning. I thought perhaps the gasoline might have an effect, but separating the glycerine, but unless it was drained out, that would be even worse. Running at full throttle causes the primary burn chamber temperatures to drop substantially lower than at half. The only part of the heater that is hotter at full throttle, is the exchanger.

[@mnp3713]

like i say it will not burn easy only 40% and a lot of work. i can burn around 60-80l pure before it clogg up and shut off. i would just like one that burn 100% wvo with no problems@@gbear1005

[@asbestomolesto]

My comment is not showin and IDK why. This is a test

[@loweredexpectations4927]

KZbin has this habit of blocking or deleting a lot of comments recently. If you say anything that has a word that could be ... well... if I try to explain it they will probably delete this comment... but yes, they are going WAY too far. They used to offer settings so that, if you wanted to, you could block or filter certain speech, and I always had it turned off.... now it appears that they have decided to just block things themselves.

the venturi effect?

[@loweredexpectations4927]

Not totally sure what you are referring to, but the venturi effect requires some pretty specific geometry. You are the second person to say this so maybe I'm missing something, haha The air form the combustion fan blows outward towards the circumference of the chamber, onto the mesh, so is not idea for the venturi effect.
