- Carbon Monoxide is a silent KILLER. Please take note of what and where you have the exhaust pipe routed.
I'm sorry to say what some have done with car exhaust but im trying to make my point clear.
Be careful folks.

Another important note is to make sure you use high temp silicone or some similar item around any flanges.
The heater shown here is different to the one I have. My own chinese heater produces very little corbon monoxide . Even woth a cabon monoxide meter directly on the end of the exaust pipe only a very small reading was observed , nothing anywhere near danger levels . And yes it was a tried and trusted meter. The gas ring on my gas cooker had a higher reading.
Just buy a carbon monoxide detector for any installation of these and you will be just fine.
Why not just keep the hotter part of the exhaust inside to capture the heat first and have the cooler portion going thru the wall?
You MUST have a monoxide alarm with these heaters, it is possible for them to leak internally into the heated air, it is also possible to tune your fuel air mix until they produce very very little monoxide even from the exhaust.. the danger is if something changes a gasket or seal fails this can shift the mixture back to producing monoxide which can then vent into the room Also the reason "some" brands were banned from import is due to very poor installation instructions with zero warnings.
The truth is that these heaters produce very little carbon monoxide . less in fact than a domestic gas cooker.
@@daviddavis6231 they do, but only when tuned correctly and everything is running correctly, move your mixture off a bit , have a gasket or seal fail or anything else that shifts the mixture, and they will spew monoxide, prime example is when the fuel pumps start to wear out and deliver less , this causes a lean burn and Co will go sky high. another is if the glowplug seal fails, this shifts the mixture while also allowing exhaust gas to leak into the room air flow.
@@robb1chan9 If you really believe what you are saying ,is fine by me. The fact is that there are virtualy millions of these heaters in use all over the world . If they are as dangerouse as you suppose ,there is no way they would be made available to the public. Do you know of any fatalities from these heaters , I do not know of one single confirmed case . You may think that I do not understand about the dangers of carbon monoxide , that assumtion would be very far from the truth . I am a time served heating engineer trained at the Brooklyn colledge in Birmingham.With a big emphasiss on the dangers of carbon monoxide . There is a tremendous ammount of scare mongering on the internet , The scare mongering about Chinese diesel heaters is no exeption.
@@daviddavis6231 Any qualified heating engineer that advises people not to have a Monoxide alarm near a combustion based heater is an absolute idiot , you are clearly not qualified at all
@@daviddavis6231 A Qualified heating enginner that doesnt recommend having a C0 Alarm near a combustion based heater where people may be sleeping? LOL would any genuinely qualified heating engineers like to comment on this? its not a case of believing I already use a high grade Co meter to tune my CDH's so i am absolutely aware of how much and how litte monoxide they can produce. a Co alarm costs 20 bucks, it's hardly a deal breaker
You have your heater in a shed as do I. I think if I were doing it again I might have everything in a secure box outside and just have the hot air coming into the work space. That would get rid of a lot of the risk of dealing with exhaust gasses and diesel spills etc. Some of the installs on here look pretty iffy and I, like yourself, am trying to cut any of the downside to a minimum. I'll probably snap another up since they're so cheap. Great heaters.
The only thing you say I agree with is don't run the exhaust inside your building
Theyve been running these safely inside truck cabs for ages. Not sure what youre talking about here.
this is a half truth, many are also in use in boats too. But those would be Eberspächer not chinese clones, the Eberspächer is made to a much stricter standard and has built in protection. they are fully certified and complaint with EU H.S rules.
, I'd like to use one of these , for an off the grid cabin , but supplying the power to it , is my concern.
Have you ever seen how the exhaust from the dieselburner is made on a lorry, on a lorry the exhaust from the dieselburner ends just under the cabin thats enough. there is so litttle carbon monoxide that if you just vent the exhaust out in the free it wil no longer be dangerous. because the very little amount of fuel you are burning over a long time.
Nice to hear comments from someone who knows what they are talking about.
There are still loads on eBay and Amazon. I know customs stopped the importation of Vevor ones owing to certification and or safety concerns but not every make.
I could be wrong but I just did a search.
It's a 1920s or 30s patented design, used everywhere.
They only banned the Vevor as it was gaining traction as popular low cost heating.
Pay your bills to the big guys, or else.
I read through all the UK government ban notices of the Vevor Diesel Heaters. The reason for the ban is the inadequacy of the installation documentations, not that the heaters are intrinsically unsafe. There were no test results or data saying that the heaters are unsafe. The complaint was that the manufacturer had not adequately told the customer how to install the heater safely. Hence not all heater manufacturer's product are banned, only those with inadequate instructions.
I've been thinking about getting one of these...... They're similar to the Eberspacher cabin heater that we had on our air cooled SAME Saturno tractor. It ran on the same fuel as the tractor and was ridiculously efficient. Lorry drivers used to have the same heaters to keep their sleeper cabs nice and toasty in winter time.
Would I be incorrect in thinking that they run from a 12v/24v DC supply? Or are they mains powered?
I'm just thinking, I could use one to heat my cabin/workshop - assuming I'll be able to get back to hobby activities in the new year.
12v 15a i think
My one can run on either 12 or 24v. Not 100% sure how, but there is a setting on my controller where you can change it. (CZcams videos also show how to do it)
Its well worth buying. Just ensure exhaust pipe is going outside!
How long tank last
Having it on the floor doesn't guarantee desending flow of the exhaust you must raise it.
The only seal provided in the heater to isolate the combustion air and the breathing air is the rubber gasket on bottom of the mounting flange. Any installation that do not seal on the gasket is potentially dangerous. You can accomplish this seal in a caravan easily. I saw people using this heater to heat home by sealing on the corrugated hot and intake breathing air. It is impossible to seal over corrugations and is potentially lethal. The plastic body of the heater is certainly not air tight and should not be placed in an environment where diesel fume or combustion product exist.
This is not correct. The gasses are separated by a fiber gasket around the flange of the burn chamber and heat exchanger. The rubber gasket at the bottom of the heater is just to keep the flow of air going over the exchanger and out the outlet, instead of escaping out the bottom, around the mounting flange.
The body of the heater is not air tight, but it is also normally under positive pressure when in operation. The only way this is not true is if you restrict the inlet side more than the outlet side. Having the heater in an area with fumes would absolutely be stupid though, as all it would take is a hose falling off to cause a deadly situation.
The fibre gaskets in the heater are the seal between breathing air and burning air no doubt. They are there by design and seal perfectly when correctly manufactured. Any breakage of these fibre gasket is a manufacturing quality issue. The rubber gasket on the other hand seals the aluminium body from the connections of burning air and the fuel inlet when the heater is installed by user. Not using this rubber gasket to isolate the breathing air from the burning air circuits is an installation mistake as opposed to manufacturer quality issues. Just imagine the installation of the heater inside a caravan. you drill a hole or holes on the floor and mount the heater sandwiching the rubber gasket. All the burning air inlet, outlet and fuel inlets are outside the caravan while the breathing air is drawn from inside the caravan and the hot breathing air delivered inside the caravan, The air tightness of the walls of the caravan separates the breathing air from the burning air circuits. This is the principal of design and installation of these heater. As such the use of the rubber gasket for isolation must be complied with.@@loweredexpectations4927
@@cfcyayaya I’m not sure if someone told you this, or if you just hypothesized it yourself, but if what you are saying is true, all of these heaters should be recalled, because I have never seen a single rubber seal that actually seals. I have never seen one that even comes close to sealing on the plastic housing. They never match up. There is also nothing to push the rubber against the plastic.
Pressure goes from high to low. Hopefully we can agree on that. If you run no gasket and loose bolts on the burn chamber flange the air pressure is equal on both sides and the exhaust is the low pressure area. If you don't understand what I mean, the air from the fan goes into the centre of the burn chamber, yes ? Around the outside of that is the flange for the chamber. The pressure on the inlet of the chamber is exactly the same as the pressure around the gasket that you think might leak. If there is any pressure differential at all, it is created by the geometry of the chamber and exchanger.
I tell you what I will do. I'm currently running a test and making a video debunking the need / benefit of quality fuel lines ... when I'm done that, I will remove the gasket and run the bolts loose, creating a leak on purpose. If it actually leaks, it will likely be leaking fresh air out the exhaust ... but we will see. I have a CO meter and air quality tester.
I understand how it may seem like you are right... this stuff is sort of confusing, but the pressure comes from the fan and pushes equally on both sides of the chamber gasket.
The rubber gasket does not seal on the plastic housing. It seals between the Aluminium flange and the wall of the caravan. The external surface of the Aluminium housing is in the breathing air space while the totally sealed internal surfaces contain the combustion air space. The plastic housing has no seal and is not necessary to be air tight since it is inside the breathing air space. Neither are there seals between the hot air duct and the plastic casing for the same reason. As soon as you put the plastic housing in an environment where CO abound, you are mixing the breathing air with the combustion product. The fibre gaskets should seal from factory. CO alarms are used to guard against the failure mode of cracked fibre gaskets. If you examine the design of the heater carefully, these will become obvious. One does not need to be told.
@@cfcyayaya For sure...the rubber is a good seal between the mounting surface and the heater body. If your heater is mounted in your breathing space, this will stop vehicle and heater gasses from passing through this mounting area. This is not what your original comment was though.
"The only seal provided in the heater to isolate the combustion air and the breathing air is the rubber gasket on bottom of the mounting flange." This is what you said. That is not correct and it threw me off. What you are now saying doesn't seem to align with what you were saying before.
"As soon as you put the plastic housing in an environment where CO abound, you are mixing the breathing air with the combustion product." This is not true. If the plastic body has a positive pressure inside, then fumes will not get in. If your inlet ducting was more restrictive than the outlet (likely not the case) then it would pull outside air in... this is how pressure works.
There are two fibre gaskets. If the chamber gasket leaks, and somehow combustion gasses get in the fan area, they still have to get past a second fibre gasket, or the glow plug seal before they are in the breathing air. If we refuse to acknowledge the laws of physics, that this air will take the least path of resistance and move form a high pressure area to low pressure area, then this could happen.
I have examined the design of these heaters in great detail. I have modified and even built my own burn chamber. I have conducted endless experiments, pushing my heater to failure literally hundreds of times. I'm happy to be proven wrong. I invite you to explain path and process for combustion gasses to get into the breathing air. "if the gaskets leak" is not an explanation, as leaking only occurs when there is a pressure differential.
Uh no, mate. 😅
I would never run one of these indoors. Too many chances for leaks.
More likely the all in one's might get banned. The one's in the red boxes.
Can be installed on it's side on the wall so all exhaust is outside.
Do you think they could be trying to ban them because it is an altetnative to paying uk gas/electric companies with a monopoly on energy prices?
Or ban them out the goodness of their heart, caring about their civilians?
Place your bets.
If you're not smart enough to understand combustion engines you shouldn't be using one. But Darwins law will take care of it
For this reason everyone should have one.
If you survive, you get to live with like minded people !
What a BS
?
Explain yourself, fool.... Feel free to share a link to a video where you did better .... we are waiting.
You sir are grossly misinformed
