What size of batteries and what is your run time? Mind sharing how you converted it!

[@FFLFFS]

@dusty1498 I imagine a small potentiometer would regulate 18v to 12 V Basicly why Vevor says not to put a battery charger on b/c that would be 14.5 volts.

@@FFLFFS Thanks I know guys use 18v drill batteries on 12v kids electric jeeps etc maybe some of those videos will translate over to use with a heater👍

[@sw5334]

@@dusty1498 I run mostly 12.0 amp batteries. At full throttle they last 3-4 hours, turned down I can get 8 hours. Depends how hot and size of room your trying to maintain. I build glass solariums so I use it while working and it does a great job. Making the conversion is a bit harder than just bolting a battery on. I’ve had a lot of people ask how I did it and I would love to do a video on it but I’ve never made a video for KZbin. I think it would be a great second video for Rich to do about the heaters. If he sees this and contacts me I could explain and show photos on what to do.

[@sw5334]

@@dusty1498 A not so quick explanation, I use a 24->12v regulator to cut the voltage down. That’s the easy part. If you’re not familiar how these diesel heaters work here’s a quick explain. When turned on, they do a self check, then heat the glo plug, then inject fuel, it burns, glo plug turns off and the unit keeps running by the little filter looking element igniting the fuel on its own. Very low current draw when it’s running as it’s only turning a fan. When you turn it off, the fuel stops, fan lowers speed, glo plug turns back on and burns off any residual fuel, then it cools off, then it shuts down. This is important to know for the batteries to work. Cause the batteries don’t turn themselves off, if you don’t shut down at the correct time you can damage your batteries by drawing them too low, or not having enough energy in the battery left to do a proper shutdown sequence. Thus sludging up the heater. So what I do is install an electronic unit that watches the battery voltage, when it gets down to a preset voltage it turns the fuel pump off, heater sees a fault code, then the heater goes through the shutdown sequence and protects the battery and heater. It’s easier to set up than this sounds.

[@SuperSecretSquirell]

Those are 100% Eberspaecher knockoffs. The good thing is when something goes wrong, any big rig dealership should be able to get you spare parts. I've rebuilt countless numbers of those things. The first thing to usually go is the gasket around the burn chamber. It cracks and starts pulling in air and causes it to not light off or stay running. Keep a spare glow pin and burn chamber gaskets and you should be able to get it up and running quickly.

[@benjurqunov]

I used to sell Espar. These knockoffs are not the quality of Espar, but at 1/10 the pricetag... Well worth it. I have a few of these China things. In my shed and both campers. Also made a portable complete kit with flex duct, battery cable, etc. I'll leave it sit outside. The air is ducted into a wall tent or whatever.

Have a remote fuel tank outside witha line feeding inside. Using a portable marine fuel tank, your capacity goes way up and you can fill it while it is still running. And keep it outside so if you spill it you aren't smelling diesel the whole winter.

[@Cj032188]

haha this is what I do.. I have a small diesel fuel pump with a line drilled into the cap of the tank. I run the line right into my gas container to fill.

[@outintheboondocks1466]

I've had one for a couple of years now. My house is completely off grid, micro hydro powered and about 1800 sq ft, and it keeps it warm in the spring and fall, but not warm enough when the temps outside are below freezing. (yeah, shouldn't have cheaped out on insulation) I have a 7 gallon external fuel tank, so on the lowest setting I can keep the house frost free for a week. I routed my exhaust into my wood stove and the natural updraft helps pull the air through the unit, at least I think it does...lol As for the recommendation of not using a battery charger, I use a maintainer, some call it a Porsche charger, and it keeps my battery up to snuff. As for the clicking noise, you get used to it! Never have run anything but dyed diesel and after probably 1000 hours of use, it's been trouble free. Great little unit and well worth the cost.

The 8k version MAY have a larger orface in the jet. The circuit may be programmed to inject more fuel per minute. The honest way to comment would be to measure the ounces er hour of fuel consumption and calculate the BTU's per once of fuel.

On an 8 the fin chamber is longer.

[@jhuck8166]

Last winter I tried diesel/oil mixes of various ratios and no matter the mix, the burn chamber would carbon up and I had to chip the stuff out of the burn chamber. The oil was filtered and I started and stopped on straight diesel. After the third time, I decided to stick with off-road diesel. For my exhaust, I mounted a 10’ section of 2” conduit 6” off the wall and used a 90 to exit the building. I used a box fan to blow on the pipe. Works great.

[@loweredexpectations4927]

I have a list of corrections that I think are important to share. I have accumulated hundreds, if not thousands of hours of testing on these heaters, and have over 30 videos showing how bad of an idea trying to burn waste oil is. The 5 and 8kw are almost always the same. Some cycle the pump a little faster and run rich in the highest setting. They don’t like being charged? Meant to be used when not moving? Please explain as this doesn't make sense. Charging while running is fine. Using these heaters while in motion is fine, as long as your set up correctly. The glow plug is for starting only. Fuel doesn’t hit it, it enters an area near it and flashes off on a mesh. This are is for flame initiation and the actual combustion happens in the chamber at a separate "wick" mesh material. (at the end of the fuel inlet) I don’t understand that the confusion is about heat energy. Things that lose heat slowly, can’t heat space quickly… you have x amount of heat and it’s either in the radiator, or in your air space. If you have a material like cast iron, that holds heat for a long time… this is NOT good … unless your goal is to have a hot radiator. I prefer a warm room. An aluminum radiator (or copper) makes way more sense. I grew up with a wood stove and furnace so I realize cast iron was used a lot... not because it heats a space after your fire goes out. The glow plug only needs to be finger tight. It doesn’t hold anything in, other than itself, and it can’t come out. The glow plug “screen” is basically a wick, not a filter. It doesn’t affect running operation at all, only start up. If it gets carbon, it I’ll effect start up only. Fuel is not filtered through this. This is not a diesel engine… it is a glorified candle, that has fuel delivered to the wick on demand. Viscosity of the fuel has almost no effect on these heaters as they use a dosing pump. Other than extreme conditions, one pulse of the pump will deliver .022ml of fluid. If the fuel is so thick the punk can’t cycle, the heater will shut off. The byproducts of blow by are combustible. Oil is made of carbon, so is diesel, and gasoline. The reason used oil doesn’t burn well isn’t because it is used, it’s because it’s oil and isn’t as refined as diesel or kerosene. It’s not the additives… diesel is refined oil. Burning oil leaves behind a what you would have refined out of diesel (for example). Mixing fuels does NOT cause the less volatile fuel to burn. Fuel doesn’t burn. The gasses that flash off burn. If you mix gasoline and diesel, in a heater, the gas will flash off instantly and you will be left with oil… just like in a distilling process. If they are injected in a mist, like in a diesel engine, then perhaps the heat of the gas burning will cause the oil to burn, but these heaters drool fuel onto a wick, they don't inject it. I have hundreds / thousands of hours on a pump that has run pure gas, alcohol, waste oil and even some diesel…. These pumps don’t wear out / fail due to lubrication. They make these units that burn gasoline and use the same pump. Pumps that fail, likely do so because of defects or moisture, causing corrosion. It's not the glow that plug screen that gets clogged with waste oil. It’s the burn chamber mesh. It’s not replaceable on most chambers, and is almost impossible to clean. Used or new veg oil can be used, but more important than filtering, is mixing at least 50/50 with diesel or kerosene. 60 diesel 40 veg oil to be “safe”. The issue is glycerin in the oil. If you remove the glycerin, you have biodiesel. I have personally done it at 60/40 and have an acquaintance who has been burning 50/50 (with a system with two pumps that mixes it) for a few months now, with no issues. The last few weeks running 24/7. 200% more efficient 🤔😤 … if you lost half of your heat out of the exhaust (you’re not) and recovered 100% of your loss… that would be 100% more efficient… no ? Such nonsense. The most you stand to gain by collecting ALL of the exhaust heat is about 1kw. The actual output of these haters is around 4.5 or 5kw (though they claim 8) It's a great idea to scavenge that heat... but I'm not sure wher the 200% number comes from. They are great heaters. They all have ticking pumps. You can easily quiet them or buy quite replacements. Detach the pump from the metal casing, as it amplifies the noise. Hang the pump form an elastic or zip tie... if the heater is stationary, this will work fine. Do NOT run them waste oil or waste oil mix in these …I have tried 80% diesel and gas with only 20% oil, and they still clog up. I have a 30 part video series on how bad of an idea this is. Hearing the oil, mixing it with diesel or gas does not help… heavy oil has ash. That ash will clog the burn chamber.

[@AncientMechanic64]

I have played with these for a few years. My advice...Burn only clean fuel, they will fail fast on used oil no matter how clean you think it is. You can run them for many, many hours on clean diesel. Run them hot before shutdown to keep them burnt clean. I made a heat exchanger from a princess auto surplus tractor muffler. I run a three foot coil of the generic chinese diesel exhaust in three coils down hill into that, with the exhaust going down. I blow an 8 inch fan up over it. Drops exhaust to almost room temperature, and recover a surprising amount of heat. I run it all on an old car battery with an old power supply supply charging it. Fuse it at 20 amps at 12 volts. They only pull 2-3 amps once they finish with the glowplug so a battery can keep my garage warm all day in a power outage

[@wallacegrommet9343]

Burn a gallon of clear kerosene once a year to clean out any carbon on the burner screen. That extends the maintenance interval on screen replacement.

Drill and tap a hole in the far end of the radiator and plug the hole the current exhaust is attached to and the radiator should heat evenly.

[@carwashadamcooper1538]

There should already be a pipe plug on the other end. If not, your idea is excellent. Either way, it needs cross flow for good heat capture and dissipation. I've removed a couple/few tons worth of those from old houses and I've never seen one with the supply and return plumbed into the same end.

[@merlepatterson]

@@carwashadamcooper1538 Yeah, I agree.

[@benjamindyer7348]

I like the radiator idea BUT the exhaust will cool enough that the moisture in the exhaust will condense into liquid water. Water that is condensed as a combustion by product is very acidic, it will rust through the bottom of that radiator in a few months. It's important to not let the exhaust of any combustion cases condense unless it's in a controlled way, in a Stainless steel heat exchanger for example. And has to he drained away in plastic piping

[@thisnthat3530]

@@carwashadamcooper1538 Water flow would be much lower than the exhaust gas flow, giving it time to rise to the top properly. With this setup the hot gasses should be piped in at the top with the outlet at the bottom for the cooled gas to escape, preferably, as you say, from the opposite end.

The 8KW are made, they larger than the 5kw. You can tune the 5kw to burn to about 8kw as you can tune a truly 8kw to burn over 10kw, but elevation plays a big factor and.... More fuel more heat means it can overheat faster and it will!. Also, yes all the parts are replaceable but they cost 1/3 the price of a new unit. The only part that's economically to replace are the bearings in the Fan, the inner ones will start to go after a year or so of tuned continuous use (heat destroys the inner bearing) .

I've even found a few that are UL Listed, for peace of mind, or that "insurance question" Mine is branded as GearBest and the other one is called WiPro. I got one with Bluetooth which is so good addition. These newer models are also more fuel efficient. I'm over 45 hours on low with 1.5 gallons. I've since upgraded my fuel supply to an external 15 gallon fuel caddy that sits under my 5th wheel. I can theoretically get 400 hours of run time 🤯 I don't know yet... Will find out here in a few weeks how long it lasts just running it at night to keep the chill off. Also... If you are really into modding these things, the first place you should be looking is a fully programmable motherboard. Gives you full control over the burn perameters and even has a schedule time on, time off function. There's a guy in Australia that sells those boards.

I think your concept of using the cast iron radiator is awesome however I think your mistake is you need to have your intake high on one side and your exhaust low and at the other side of the radiator. This way the hot exhaust has to run all the way across the radiator and as it cools will drop and exit the low exhaust port. Keep up the excellent work.

[@TheMajictech]

The screen isn’t to filter anything, it gets hotter than hell negating the need for the glow plug to remain on. The plugs only used for a minute or so to get it started then the atomizer screen/ flame front takes it from there.

[@ozarkmartin1174]

Great timing, just bought one a few weeks ago. Pretty fitting my favorite diesel channel reviews them!

[@TechOne7671]

Good video Rich. Take the top bung out of one end of the radiator and feed the exhaust into it then connect the opposite lower end to outside. This will create full Cross flow from top to bottom and side to side giving maximum heat transfer. All the best.

[@Grasshopper.80]

After everything I’ve seen on this platform a bulkhead heater like what’s used in the marine industry is the best. Low or no power consumption. I hope to make my own.

[@NordicDan]

I clicked on this planning to recommend the radiator addition and thinking I was all slick, but it seems you've already thought of that! 😂 Matter of fact your radiator is nearly identical to mine, only mine is slightly taller and has fewer sections. The issue I'm having at this point is where to source appropriate sized fittings and adapters so that I can clamp the exhaust lines to the radiator. Luckily it looks like I can reuse the two plugs that are already in place. One recommendation I would make for the sake of better heat scavenging from the radiator would be to keep the heater connected to the bottom like you have it, but relocate the radiator's outlet to the opposite end on top. This will force the exhaust gas to travel all the way through the radiator, and if you run it for more than a couple hours at a time, it'll get warm enough to prevent condensation and prolong the life of the radiator.

[@hustleeveryday6582]

Wish you'd published this video a few months ago. My brand-new $1500 EBERSPAECHER AM3 D4R has given me a ton of grief and since they redesigned the burner (welding the atomizer screen into place) it REALLY SUCKS TO SERVICE. Replacing the atomizer on these costs over 200USD. BUY CHINESE.

Well that was by far the most useful clip about Diesel Heaters on the KZbin! Thanks for the breakdown!

[@stevenoe6395]

The only difference i have seen on some models is the programming between the 5k and 8k the 8k usually can turn the Hz up more. The muffler that comes with them should have a hole on the bottom for condensation to escape when it cools back to water those things put out a lot of condensation and when it doesn't have any place to escape when it cools down it rusts out the cheap flexible exhaust pipe. I bought a $50 ebay one last year but never got to mess with it because I went into the hospital then it got put in storage planning on playing with it this year I have a couple boiler heater pipes with the aluminum fins I plan to hook up with the exhaust and make it all run down hill well that is once I get the extra time recovery has been a pain I do construction and it's gas been rough lol. Good luck with the heaters I have herd good things about the Bluetooth vevor heaters supposed to be the best cheap ones you can get definitely a lot of stuff out there for upgrades for all of them and I really want to play with the used oil see if I can get that working decent!!!! Good luck!!!!

[@Rockport1911]

Sadly nobody tried turbocharging one of these yet :) But utilizing the exhaust hot air to further heat the space isnt bad, just gotta watch airflow and condensation...

[@hankstar.1]

I used to work on these espar heaters. My old boss had a fleet of around 70 trucks and everyone of them had a espar heater. Pretty much the same exact thing. The plastic was never am issue the metal case gets hot and air moves over it thats how it was designed to make heat. Poor fuel would cake these things up with carbon deposits and then it couldn't hold a consistent flame. Also the igniters like to go out. Or glow plug whatever you want to call it.

Bought a second one for my other small shop or if needed I can double up in the one shop

[@Ocean_breezes]

I love those cast iron heaters. We had those when I was a kid in the 1960s. Didn't think they made them anymore

[@wild_buckwheat]

A by-product of combustion is water. We've all seen the steam and water dripping out of a car's exhaust pipe at idle on a cold day. That water vapour in the exhaust absorbs other by-products of combustion which are very acidic. Exhaust needs to be hot so that the very acidic water vapour stays a vapour and doesn't linger in the exhaust system. If the exhaust is cooled too far then the water vapour condenses and now you have very acidic condensate water in your exhaust system. That acidic condensate will quickly rust out any exhaust system. Your radiator will take a long time to rust out because it is very thick and will see limited use. For every day use I doubt it would last much past 2 years. That's fine if you have a scrapyard full of replacements next door and are willing to spend time replacing it. Just thought it was worth a mention. Your radiator is a very simple idea to capture some heat, but you'll notice the exhaust on literally anything that uses combustion is hot, and acidic condensate quickly rusting everything out is the reason why.

[@TronJockey]

True. I'd consider using stainless steel automotive exhaust pipe. A long enough piece with a few curves should provide sufficient surface area to transfer heat without worrying about the acidic condensation which could be allowed to simply run out of the end.

[@DEBOSSGARAGE]

Thanks for that! A drain on the bottom will solve that issue I'm sure, but it won't see much use. Just once in a while. The main use for the heater will be in the Land Rovers while camping in the winter

[@daszieher]

​@@TronJockeyI'd use a heat exchanger to heat water and run the radiator with water instead of exhaust gases.

[@TronJockey]

@@daszieher - I was trying to extract as much heat as possible as simply and cheaply as possible. The heat exchanger idea is interesting; however you would still have to deal with corrosive exhaust byproducts interacting with the heat exchanger itself. I'm not familiar with all types of heat exchangers so maybe they make a stainless-steel version that could handle a corrosive environment. Might be expensive though. Alternatively, for the more frugal individuals, one could coil a length of copper tube around the exhaust pipe (soldered or brazed to the steel pipe), to act as a conduit for an ethylene or propylene glycol mixture. But all this starts to get complicated (and likely expensive as well).

[@asbjrnkvisle5831]

True. But the time it takes to rust out depends very much on the quality of the fuel you use. Better combustion, less acid water.

[@Pippy1]

Most of them are nowhere near this loud

[@consolehacker54]

I like my 8KW Vevor with a small 4" metal duct setup, my garage is about the worst case scenario for attempting to heat it. It's fairly large, dirt floor (which I did cover with plastic), wood siding with no inside wall (so the wall is basically 1/4" thick wood), no ceiling. I'm working on all of that like some form of insulation and a ceiling to help hold the heat in, but even considering all that it at least brings the temp up ~15 degrees so it goes from literally freezing to tolerable without an entire winter coat on. Should perform much better once I update the garage. When the outside temp is closer to 55 than 25 like fall weather it works great even as is

[@paulen1964]

I have 3 of these diesel burners from vevor and none of them produce 8kW. All of them are around 5kW and I think it all boils down to the fact that they send these out with too small a pump. I also got this confirmed indirectly from Vevor. They send with a 22ml pump and you need a 40-65ml pump to get these up to 8kW. diesel has around 10-11kW per liter and when you burn around 0.5 liters per hour it can never be 8kW.

[@minionkevin6623]

Well you definitely answered my #1 question with these heaters. Will it run on "other fluids/mixturs". 🤘Thanks man!!!

[@Inwetrust-qy2ly]

Wrap some insulation or k wool around the fuel pump to quiet it drastically.

[@TheGalifrey]

The outside fan can never fail while the heater is running as the same shaft runs the heater core fan. If one stops the heater will flame out.

[@triton199]

ive got a nearly identical heater rated 5-8kw branded Hcalory, works pretty well. my garage is old and basically uninsulated other than some 4mil plastic stapled to the walls and tarps hung up to wall off the back 2/3rds from the side with the garage door. manages to keep the warm side about 62-64 degrees even when outside temps are down in the 20s, hovers upper 30s low 40s other side of the tarps because of heat loss thru the uninsulated metal door and air gaps around it. get at least 8 hours a gallon even running full blast the whole time. love the heatsink idea, might implement that if i can turn up an old cast iron radiator cheap enough, better than blowing all that potential heat outside

[@rtz549]

If you don't open the door very often; run painters tape around it to seal it. Or some foam weather stripping from Home Depot.

[@ridgwalkerg]

Thanks , that was a good quality video. Its rediculous the cost of used semi truck heaters, a good heat exchanger, and my desel truck would be so happy, my fuel tank is behind my seat, also. Your right about thinning any mixture, and the exhaust coking up also. Id insulate the exhaust outside to prevent it from coking/caking on

[@BrodieBr0]

Dang that's a nice trick using that old cast iron raidiator! I got one laying around and didn't even think of using it. 👍

[@Trains-With-Shane]

Good to find that these things are pretty serviceable. Might not be a bad idea to stock up on a few gaskets, screens, maybe a glow plug and a fuel pump to have spares on hand. That is unless the cost of another complete unit is less than a small supply of service parts, lol.

[@cortlundtowell5252]

I use my vevor heater while camping. I just mix in my old oil from my Jeep (0w-20) into a jerry can with about 2 gal or less. the oil is light enough that I'm not too concerned with it tearing up the heater pump. the deisel is in there to help with ignition only. If it's below 38ish outside, it takes forever to get straight 0w-20 to ignite.

[@LostDeadSoul]

What I guess you and most others are not doing is cleaning your waste oil before burning it in your "clean burn furnace". I acquired diesel and gas mix from an automotive shop across the street to our automotive shop. Also got oil from multiple other places so I had a lot. I put 700 liters of thick oil in a 1000 liter tank. Thinned the oil with diesel/gas mix until the viscosity was good to run a centrifugal oil filter. Then I ran the centrifuge for 8 hours. The combustion chamber and heatexchanger only had about 0.3mm of ash in it after half a year. That compared to having to shovel ash out of the combustion chamber and exchanger every half a year. About half of the year we ran the heater using up to 1000 liters a month. I'm not there any more, hence the "we ran". But I'm guessing that might also help that chinese burner last alot longer with regards to the ash.

[@landrover325]

The glow plug turns off after a bit. And it relies on the glowing screen to sustain combustion. The fuel just drips into the port, the pump is a metering device. No squirting, no injecting. Just a few steps past a lantern.

[@VMac822]

That’s exactly how I have believed it functions. The glow plug definitely runs only for a short period of time. Otherwise it would kill the battery. I’ve been able to run mine for a dozen plus hours on a very small ATV battery.

[@crankshaft007]

thanks for video, just FYI, they do not make any units with quieter pump. James in the UK makes a completely different pump that is silent, great upgrade. You mentioned something about this unit being legal and covered under house insurance ?? I seriously recommend you do some research before saying such comments.. MANY of these Chinese companies do not have REAL CSA certification. They just print they all on the back, but if you do look up the certification its fake. Haven't watched the channel for a while but I would highly recommend adding at the start if you purchased the item with your own money or sent for free. Forgot to mention as well its not recommended to add restrictions to the exhaust system. The small internal fan is not made to push exhaust thru a huge heat exchanger.

[@briananderson1781]

Have you tried centrifugal filters? I bought a used tractor truck which I converted to a straight flat dump farm truck, this truck came with a centrifugal filter added on when it was new and it does seem to work. I clean the centrifuge each time I change oil and it has a coating of carbon like deposits.

From there I have a second 12v pump that pumps into a 5 gallon fuel can that I fill halfway with diesel from the transfer tank in my truck. Been going strong on the 50/50 filtered used oil and red diesel for 2 years now on my 5Kw vever heater

[@Lagittaja]

The used radiator is a good idea. However your specific type of radiator maybe not the best. I think that's a steam radiator? I would try to find a radiator that has connections at the top and bottom. In my apartment the water filled radiators have the inlet on top and outlet on the bottom. For running diesel heater exhaust through, you would obviously reverse the flow direction with that type of radiator. When it eventually clogs up, just replace it.

[@Lagittaja]

Although obviously a vintage steam radiator will flow more easily due to the larger internal diameters. I would try and find one with inlet and outlet on opposite sides on the bottom, those should exist based on a quick search. Or find one that has extra ports on the top, I don't know what their purpose is, probably for cleaning? That would be best, you'd be able to choose the best flow path for your situation. Maybe these types can be cleaned and prolong their useful life before the other passages clog up.

[@wobblysauce]

It works, just it is a lot of mass to heat from cool, but once at temp it will do well.

[@zachary3777]

​@@wobblysaucethe exhaust gas isn't flowing through the whole rad. It's basically staying in the first chamber. With steam, the temperature difference creates a large pressure differential that draws steam into cold spots in the radiator, where it condenses.

[@Lagittaja]

@@wobblysauce Well, I did say "maybe not the best". Sure, it will work. The radiator he used might have an internal baffle to prevent the hot exhaust from immediately flowing towards the exit. But the thermal camera did show that only the closest chamber to the inlet/outlet started warming up significantly faster at the top than the rest. Sure, the whole thing will eventually warm up from conduction but if the exhaust was forced to flow from one end to the other, the whole thing would heat up faster and overall extract more heat from the exhaust before exiting the radiator.

[@haydenc2742]

Yeah...pump in the hot gas on the top fitting, exhaust on the bottom, plug one of the holes out...would definitely heat it much better, all that cast iron would take a long time to heat...but would also hold a TON of heat...even a cheap fan blowing across it would increase the heat output as well

[@Jam3s2001]

I run one of these on "processed" vegetable oil, or biodiesel-ish. Mix some lye with some methanol (heet) and then add to filtered, spent veggie oil, mix it up real good, remove the soap from the oil and then run it in the heater. Burns really clean, starts/stops every time.

[@schraubnix1583]

It is a good idea to bring the heater up to operating temperature first and only then switch to the preheated oil diesel mix. However, you should switch back to diesel before you switch off the heating and let the heating continue to run at the highest level so that the soot can burn off. If you don't do this, the heating will sooner or later fail because it is dirty. Greets from Essen ( Germany , Ruhrarea )

You are the millionth person to point out the nonsense with the oil radiator. The exhaust cools down too much and after a short time the diesel heater becomes sooty. If that were possible, the Chinese would also be introducing exhaust heaters. Think about it.

The Arktronic pumps are far quieter, maybe spring for a high dollar german fuel pump and just replace the china one. I have had a Arktronic in my camper for 3 years in Alaska and that little diesel heater will run you out of the camper on high in about 5 minutes if your not careful. I plumbed mine to run off a rotopax on the outside wall with QD fuel line disconect so its easy to fill up. A lady I know who runs a remote roadhouse 80 miles off the road system uses one of the vevors to heat her battery building off the solar and generator. She said 1 of them for the battery building used a 50 gallon drum of Jet A last winter for the whole winter in there. Which thats not half bad for fuel economy.

Yes ypu can use an old radiator as an heat exchanger, but don't forget about condensation. The burning of oil produces h2o, co2 mainly and ash as the byproduct. Ash is because of the impureties.
