Free heating fuel but it's illegal - £120 8kw Diesel parking heater review from VEVOR

[@joshuadelisle]

!!PLEASE READ BEFORE COMMENTING!! I've done a follow up video as I understand now that it's impossible to be 8kw as diesel doesn't contain that much energy in the 350ml that I tested. So I've conduct a new experiment to calculate the actual heat output. I've also be testing how much electricity these consume at different Hz and also use the exhaust to boil water. Please let me know if there is anything else you would like to see tested in the future videos. Watch the follow up here: kzbin.info/www/bejne/aqXMhHh9hJujj6s Thank you Cheers J

[@TheManFrayBentos]

You'll probably find it's more like 4 to 5kW - some of them are even smaller. The actual 2kW ones, sold as such, have a lower rate pump. I don't think any of the cheap ones are a genuine 8kW, that's all bullchit.

[@bigduphusaj162]

I fitted these on boats and lorries for years, I'm a boat builder now so still deal with them and if set up correctly they last forever👍 First thing mate you need to swap that exhaust around so its not all exiting facing directly down as you generate extra heat in the underplate and if left on constantly for days the burner will be running maybe 5deg over what it should and using more fuel and the bend you cant have it so water and unburnt diesel stores in it or it will have start-up issues. Route the exhaust slightly downwards all the way from the unit so have it come out and down slightly then where it goes outside put your 90 bend sideways and facing downwards then have the exhaust aimed out at a slight dangle downwards so no water or unburnt fuel can store up anywhere on the pipe. Secondly you should fit the heat hose to the front as it brings the heat away from the burner nozzle and in turn saves fuel as its then burning at a perfect 163-167deg and 14:1 on the fuel. The best modification you can make for performance is to fit rigid type fuel lines like you get on the boats. They do cheap copy kits that the fuel line is nearly rigid and fits into rubber fuel hose and is clamped together. These ensure the fueling is absolutely accurate as there is no flex or expanding action happening when the pump is on its press stroke, the burner itself will be quieter and the fuel pump will last a lot longer with rigid type fuel hose🙏 What never to do > fit filters over the intake. Put too many bends in the exhaust or burner intake. Extend the wiring without doing the maths relating to wire resistance and if possible always use it on a 12v or 24v DC as mains power can sometimes have power cuts or large spikes that flip breakers... if that happens your heater is toast as it shuts down hard with no shut down sequence, this burns the internal pcb and internal wiring. The genuine ones can take about 5-6 hard shut downs before you need to replace certain parts of the electrics. Also do some homework at what height and angle the pump likes to be at as these all in ones are known for bad fuel lines and pumps facing the wrong direction. To quieten the pump down you can get the pink rubber cover thing for it and mount it so it's not touching anything. Never buy the garbage large thin tanks they all leak and the connector is a nightmare to snug up properly. If using a 5 gallon drum be sure to fit the blue lid on your current tank to it as it needs to breathe.

[@user-pf5xq3lq8i]

Good. I saw an off-grid video capture some exhaust heat. He did it by having the exhaust run diagonally down through an oil drum filled with oil, before exiting through the wall. So he created a long lasting oil radiator for nighttime when the heater is switched off the oil drum still retains heat through the night, also he had are reflector on the wall behind the drum to push heat out into the room. You must have the exhaust going downwards always as it cools because liquid could condense and clog if you run an exhaust uphill. A good downhill run and keep the pipe clean.

[@bigduphusaj162]

@@user-pf5xq3lq8i yeah mate the exhaust angle and pump angle affect the proper ones never mind these cheap copies. People dont realise how well these can run and how efficient they can be untill the really dial them in. Its the controllers ability to adapt to its targets like a car ECU that allows even badly fitted ones to run decent enough for a while but the difference in fuel savings and reliability (especially start-ups) from a well plumbed in one from one that's just been kicked into the corner and fuel thrown in it... is night and day. Honestly the 5kw versions that are sold as the 8kw cheapo model you can get the burner running at like 160deg even down low around the 2Hz mark (5kw usually go to 5.5Hz on the pump) with basic fuel line upgrade to rigid and some tweaking in the hidden menu to get the AFR perfect. Straight out of the box if you have a well made one youl be lucky if the burner is at 125deg at lower settings like 2.5Hz so dialling these things in can save you ridiculous amounts of fuel costs. The upper boundary of what any given 5kw unit will do is when the burner can run around 160-167deg as low as 2.6Hz on the pump with an ambient between 20 and 30deg.. and not need plugs every year because you leaned it out too far. That's the absolute sweet spot for any machine.

[@bigduphusaj162]

@@s1dew1nd3r4 see the Doblo van being smaller you don't need the 5kw (sold as a 8kw cheapo version) For instance a large Scania V8 T-cab only has a genuine 2kw and it can turn the cab into an oven if you leave them flat out on highest setting for more than about 15-20mins down to even -15deg outside temp. Truly the truck ones are all overkill they will even dry your eyes and throat out if you leave them on full power for anymore than a half hour. Based on that the 5kw is overkill for your application plus if you decided on the 5kw to run on low settings you'd still need to run it flat out every now and again to clear it through and on the shut down sequence when the fan goes flat out and it activates the heater plug for the final few pumps its going to near blow your windows out as the 5kw turn into a leaf blower on shutdown sequence. < These are my reasons for why you should go 2kw. Whatever you choose the wiring up side I would tap into and wire from a constant 12v circuit so it never hard shuts down by accident (and melts the guts out) if for instance you had it wired to ignition circuits when you turned the key off you would hard shutdown the unit. Wire it direct to a constant 12v but also add a switch so you can cut the power to the unit so it isn't draining your battery with the LCD controller unit being live all the time. See the switch/ circuit breaker you put in get a decent one and wire the maintenance charger wires on the connectors that are on the wire coming from your constant 12v circuit to your master switch/breaker. This ensures the maintenance charger isn't on the wrong circuit and supplying a charge to the unit itself when the switch is off. You need the maintenance charger to be charging on the live battery side of the circuit and not after the switch. You'd be suprised how many people make that mistake and wonder why their C-Tek or Optimate goes ape on them. The fueling I would get a proper sender unit or make as close to the genuine one as you can or simply just use the 5ltr one you get in the 5kw all in one units or a Jerry can with a diaphragm in the cap or a breather. The noise in cars/vans/trucks/boats can be annoying AF with the pump ticking if you have either hard mounted the pump or it's touching anything. If you are going for an all in one then your going to be stripping it to fit it so on the fitment I'd get the pink rubber pump thing that everyone buys to quieten them down and I'd mount that with rubber bungs and make sure to keep the fuel lines near the pump away from the body of the vehicle as they too will transfer the ticking noise. See the exhaust you need to pay attention to which silencer you buy as there is generally 2 types of cheapo ones, one is good one is rubbish, the good ones have welds around them not just folded and tacked, make sure on fitment of silencer the drain hole faces downward as this is another common mistake. Heat wise as long as the exhaust isn't too close to anything fluffy fabric or anywhere junk gathers up and you're good to go. Aim the pipe back into the direction of airflow to prevent blowback when you are driving, you don't want it blowing the burner out via the exhaust. The hottest part of the entire unit will be the first bend you put on the exhaust underneath it. Personally if I wasn't running it all the time I'd just do it off the 5ltr tank for the all in one or an outboard motor Jerry can you know the ones that already have the fuel line feed and a breather on the cap. They work amazing for these heaters I put them in a lot of the fitments I do on boats.

[@bigduphusaj162]

@@s1dew1nd3r4 if you need proper detailed fitment ideas mate it's no problem. The comment I left above is just my first thoughts on the matter but even when I talk about the maintenance charger I'm thinking you're using mains at a campsite or a genny to charge the battery while the van is in situ. If you're not needing it to be a campervan and not running the heater for 24hr+ with the engine off then you're fine as the 2kw barely use any battery power after the initial start up. If you are keeping the single battery setup in the Doblo then you need it to be able to start the car at all times, the heater controller itself is capable of doing a decent job of that so you would go into the hidden menu and set the "low voltage shutdown" to 11.9v so the unit itself shuts down when it reaches 11.6v not the 10.5v or whatever the unit comes set at. You won't get your engine going if it drains the battery to 10.5v With car batteries they only work well as a 'starter motor' battery above 11.6v anything below this they lose their Cranking ability. Hope this helps further.

I'm in the States & use a diesel heater to heat my workshop. I found that it runs on diesel, kerosene, and Type A Jet fuel but I haven't tried biofuel yet. Kerosene is expensive here and diesel is $4.89 a gallon so I go to a nearby small airfield and buy 10 gallons of Type A Jet fuel for only $3.80 a gallon. The only hitch is that the nozzle of an aircraft self-serve pump won't fit into a standard fuel jug opening so I had to buy two 5 gallon wide-mouth fuel jugs which have a large enough opening. A company named U-Jug makes them. In short, burning Type A in these heaters is a lot less expensive than using diesel fuel or kerosene. I haven't bothered to measure it but I think I get a longer burn on a gallon of Type A than I do on diesel fuel.

Their units had both a spark and glow plug for intitial ignition. They ran on gasoline, not diesel. Your high power consumption on startup is from the glow plug.

Couple of suggestions from cold wintery Finland: Calculate the price comparison calculations via the thermal energy of diesel also. 350ml an hour is not 8kW - even at 100% effienciency. More like half of it. Also you have losses (exhaust, which you could utilize. Also consider taking air to burn from outside as now you are drawing cold air into the room for the unit to burn (this depends on your needs to ventilate but especially true if you have a ventilation system with heat re-capturing (heat exchanger between the hot-out and cold-in, like we have in the cold countries). Last thing is to insulate that gap under the sheet metal with some fire proof rock/glass wool. Now you have an unisulated spot there.... Or you could run the exhaust inside a long vent tube in and have your fresh air already preheated.

[@peterbetts8740]

Diesel is easy to work out - it contains 10kWh per litre If he used 350ml in one hour - the machine was producing, *in total*, 3.5kWatts Of which easily half was going out through the exhaust. Just goes to show you don't need much heat energy to warm up a given space - if it's reasonably well-insulated and not draughty. A modest paraffin (kerosene) heater would do instead. No noise. No electrics needed and 100% heat output from similarly energy-dense fuel. Kerosene presently priced at about half the quoted price of red diesel. Small greenhouse heaters can be had for about £30 each Depending on room size (do check this) but in the UK, if the thing is rated at 5kW or less (500ml consumption per hour) you don't need a flue but get a carbon monoxide alarm anyway. Same applies to any fuel, natural gas, butane or propane. And the joy of the greenhouse heater is instant set-up and portability

[@paullangton-rogers2390]

@@peterbetts8740 Are paraffin heaters safe to use in a resident setting? Those used to be popular in the old days before modern central heating didn't they. You hear horror stories about people dying from carbon monoxide poisoning from falling asleep with one of those running in the same room either due to them being defective or no proper ventilation for the fumes..like you said though it comes down to having proper ventilation and a good carbon monoxide alarm detector. I expect modern paraffin heaters with technology built in are a lot safer than the old ones of the 1950's-1970's era. I used to work for a company which designed and manufactured carbon monoxide detection, measurement and alarm devices for industrial use but I didn't have much involvement in that side of their business. We used to sell a lot of them to breweries around the world I remember though!

[@usanineoneone]

​@@peterbetts8740 Agreed. Using mains gas in the UK is nearly 3 times cheaper per Kw/h than using red diesel. Also remember, it doesn't take much energy to heat up air. The problem is, the walls, the floor and all the furniture and items are cold and will slowly absorb heat energy, so as soon as you turn off the heater, the temperature will drop rapidly. The question is, how long does it take to heat up the room and all the items in it. I'm sure it's good for workshops, but not really practical for domestic homes.

[@TheTwistedStone]

Fitted one to my house ! There was an 8" extractor fan in the kitchen I could temporarily remove to fit two 4" pipes through to the inside of the house, the heater itself is mounted on the outside which is under cover from a canopy we have at the back. Have it on setting number 4 but sometimes as low as 2 with the fan speed increased. Powered using a 12v car battery topped up regularly with a small 3 stage charger. It will run on battery for around 7-10 hours but it does use a fair few amps when the glow plug is lit on startup, after that it doesn't pull much at all... Downstairs gets toasty in no time but takes about an hour or so before you can feel the heat upstairs. Came with 10ltr tank and having to use normal diesel but I do get about a week out of it for an average of 5-6 hours a night.... Usually pay £15-£18 to refill every week depending how much is left in the tank. I will do a video if anyone interested....

Got one of these. The tank above the burner is bloody dangerous in my opinion. I had a diesel leak from the hose going from the tank, there was diesel everywhere and a fog of white diesel smoke coming through the air ducts because the leaked diesel had been pulled in to the air inlet. There was also a lot of diesel around the exhaust, dripping on to it and smoking something fierce. I've since put the tank and the pump outside the casing, as well as added a filter. It's now much safer, and I can fill up the tank while the heater is running without worrying about spilling. It manages around 5KW I'd say, and it burns clean and is relatively quiet. With the modifications, I am now quite happy with it.

[@Krb-d8n]

The air intake hose is there to go outside of the building so that the air that you burn is not the heated air from inside causing a draft of cold air to come into the building to replace it. That burner uses a lot of air so in a small shop like yours, the cold air coming in will be quite noticeable. The heater I had came with a wall vent that the exhaust went out of the building though a metal tube that was surrounded by another tube. The exhaust went out the center tube and the air for the burner came into the building through outer tube preheating the combustion air and keeping the wall from getting heated by the exhaust.

[@grabbagool]

if you want to spend even less on heat there are a couple things you can do. 1 you can scavenge more heat from the exhaust before dumping it outside the wall. and 2 you can plumb the intake so it takes air from outside, because as it is since it's intaking air from inside and then exhausting it outside it must necessarily be sucking cold outside air into the workshop through what little gaps there are in the walls.

[@escapetherace1943]

it's true but a workshop is so drafty typically the difference is....negligible unless your space is very air tight. Intake should be outside of course when possible.

[@MetaView7]

cold air burns more efficiently because it has more oxygen.

[@MetaView7]

the exhaust pipe is hot. Really hot. It can go lower down the wall before venting outside. Also, slanting the pipe at an angle will help the ambient air capture more of its heat.

[@Danny01921]

True. But make sure the exhaust fumes aren't sucked back up the air inlet

A coaxial pipe would do the job! The exhaust pre heats the intake to avoid running freezing air in the combustion chamber. And only one hole going outside.

Some of these diesel heaters come with this green, flexible fuel line, which is fine from the tank to the pump, but the pump puts out such a small pressurized pulse that the green line expands and minimizes the quality of the analyzation in the commotion chamber.

I've been using the exact heater for over 4 years now and it has worked flawlessly. I do however use Clear diesel as I found that the diesel fuel with dye in it tends to Coke up the glow plug which will either require cleaning or replacement, which is no big deal. By the way yes it does require a special socket to remove the glow plug which is also readily available at very little cost. I have three of these particular heaters one of which I use in the house which is mounted on a small inexpensive Harbor Freight welding cart. The welding cart holds the battery, the heater and a solar charge controller connected to a small solar panel which makes this a totally self-contained unit. One of the other units I have I use for a small hunting cabin, and the third I use to heat my garage. I highly recommend these to everyone I speak with and they are quite popular as well with my friends that have ice fishing shanties. I don't use mine 24 hours a day or when sleeping but I do use it all day long and with a full tank of fuel it will easily Heat my 700 square foot cabin using only about one tank every 2 days when set on some of the lower settings, " on two or three ". they're absolutely amazing and I highly recommend them to anyone! Just be sure to properly install the exhaust, that's the most critical item, plus I found the hose clamps they come with to be of very poor quality and I highly recommend that you replace the exhaust pipe one for a high quality all stainless heavy duty Marine type hose clamp and you'll have no issues with exhaust smell or exhaust leakage.

You might consider running an inlet air duct from outside. Cold air being pulled into the room from outside through small air gaps due to the negative pressure created by the heater pumping its exhaust to outside can really hurt your heating efficiency. Just make sure your air inlet is far away from any exhaust pipes. Even better, would be to setup a heat exchanger where the intake air is pre-warmed by the heater's exhaust.

For the internal part of the exhaust pipe you may craft a custom heatsink with a 12V-PC-fan to convert even the excess exhaust heat to additional energy. This may make the machine even more efficient. Or you may craft your own pipe and lay it through the room. Does create some custom work but it will make it even cheaper over long distance and more efficient and environmentally friendly. AtL. a bit.

My thoughts on the "filter", its meant to be outside so you don't create a draft and suck cold air into the room like you would if the intake is inside. The plastic mesh is just to stop spiders from going in the air intake and clogging it up with webs.

The intake can also be inside for faster heating by recirculating hot air that is already inside the room instead of sucking cold fresh air from the outside. Every modern car has the recirculating option.

The combustion section is a closed system and doesn't mix with the shop air if the intake is routed outside.

[@realulli]

If you build a setup that will cool the exhaust gas to below 100C, you'll get another boost in efficiency, since you're burning hydrocarbons. Part of the exhaust will be steam. If you make that condense out, you get all the energy from turning water into steam back. Watch out: the other exhaust main component is CO2, which forms a minor acid with water. You'll need stainless steel or ceramic piping for the exhaust, otherwise it will corrode really quickly.

You have to check the different kinds available. Google up some truck shows and start visiting them see what is on the market these days. Every major city has one Salt Lake Anaheim Dallas.

A few suggestions from an aged observer of alternative fuels. Mr Diesels engine was originally designed to run on Peanut oil, that particular point is not entirely relevant but keep it in mind, diesels do not need diesel to run on, regular diesel is just usually cheaper and easier that the legal alternatives. In the past there are plenty of people who have run engines/ cars on waste cooking oil, vegetable oil, waste oil. The best practice for running these engines and prolonging their life was to start and stop them on regular diesel, warm them to working temperature then switch to the alternative fuel. The heat generated from the diesel warm up was used to pre heat the alternative fuel and ensure that it could flow freely in the pipes. The shut down process switched back to regular diesel in order to flush the alternative fuel from the feed pipes and ensure clog free starting. This was mainly to ensure that certain waste cooking oils etc. were at sufficient temperature that they could flow freely and not clog pipes. This would all depend on which alternative fuel you were to elect to use. I have seen plenty of people use these heaters (in the basic unit configuration) to heat mobile homes, live in vans etc. many have had success, a few have had problems and some have changed to alternatives. It would appear to be that you pays you money and takes your chances, some people have come to the conclusion that the basic heater should be changed every year because it is cheap Chinese stuff, others go till it breaks then replace.

This is a great video, and you obviously have the right attitude about helping people improve their situation in these increasingly hard times. I think you did a great job here, and I just wanted to add something that might help someone understand something that could be life saving. because of the trade I worked in (and still do in a less formal capacity due to age and health) I have spent a fair bit of time around many many different versions of this basic design of heater. Edit: as another commenter says further down, CO is actually neutrally buoyant in air, it's CO2 that sinks. Still, all the rest applies, and of course CO2 is toxic and also a product of combustion. All I can say is my exams were many years ago, and it seems I need to double check my terrible memory more often. To the commenter that brought this to my attention, thanks again, mits important that info like this be accurate, and I appreciate the reminder. As a journeyman pipe fitter, gasfitter and plumber, which is the set of trades in Canada which deal with gas fired appliances, I want to offer an EXTREMELY serious warning. Do NOT operate units like this without a carbon monoxide detector, plus a backup carbon monoxide detector installed in the room. I would suggest one near the unit, and above it, which will detect any exhaust gasses escaping the heat exchanger warm enough to rise (carbon monoxide normally sinks, but hot gases rise), place the other one at least a foot below the level at which the mouth and nose of any person in the room would be located. So if its a sleeping room, have the second detector near the floor. A workshop with a pit of any kind should have a third detector down in the pit. If in a room heated by a gas fired appliance you start to feel your eyes burn or develop a headache, shut the heater off and leave the room IMMEDIATLY. Look up the symptoms of carbon monoxide poisoning and understand them, and explain them to those others who use thew room as well. Cheap heat exchangers tend to corrode, and bad welds sometimes crack, either of these will result in the products of combustion entering your breathing air, which is extremely dangerous. Heaters like this are cheap partly because they are less well constructed, so make sure there are no holes or cracks in the heat exchanger when it arrives, and inspect it carefully OFTEN to make sure heat cycling has not created any cracks. Properly used by someone who takes adequate provisions for carbon monoxide detection, understands how to maintain good combustion in the burner, and who inspects for wear and damage is fairly safe, but there is a greater risk using a product like this than from alternatives. I personally would use a heater like this because I am well versed in how they might fail, and how to be safe, but if you are not properly informed, BECOME INFORMED before you install something like this. .ot's of people use them all over the world, a similar system heats my camper, and truckers often use them in their sleeper cabs. it can reach -50 here for weeks, and they work great. Oh and lastly: If you have pets, understand that since they breath so close to the ground, they will die of poisoning before normal detectors that install above the floor may even ring the alarm, so ensure ground level detection of carbon monoxide gas exists if you have a shop cat. The only carbon monoxide fatality I knew personally was a friends very beloved dog, who slept curled up near a heater like this one. It was very sad, my friend had never thought about the possibility that the first person to start breathing CO would be his dog, and had his detectors mounted in places that made sense for people in a workshop, but not a wheezy old bulldog that slept on a cushion in the warmest part of the shop. It might not be just you that you need to protect. Again, GREAT video, great channel in fact, keep up the great work, you have a subscriber in me.

If the line is cut to length accurately, it will stay in place without adhesive. If needed use some contact adhesive to affix the re-purposed fuel line.

I have had one of these since 2017. 6 years later still going strong no complaints whatsoever

[@paulwyand6204]

I think the intake tube filter/muffler is supposed to balance the intake exhaust to help with an efficient burn. I know in boat installs they say to match the length of intake to the exhaust.

[@bigduphusaj162]

I'm exactly that a boat builder and I fitted these for years too. You are correct but the full story is that in boat applications the runs are sometimes huge so you need rigid type fuel lines so there's no expansion in them and you need to know how to programme the hidden settings for fan voltage and AFR so you can then dial the unit in so the burner temp is perfect 167deg with 20deg ambient intake and 14:1 AFR and if its not 20deg at the time you need to do your maths and suit it to your ambient temp to get it running perfect. Typically on boats the fueling needs messed about with the most and it's always adding to the pump frequency so they burn more fuel in general. In a garage or whatever if I had a larger one (the cheap copy 8kw are really a 5kw) you can get away with leaning them out a bit to save fuel as long as you know its likely to go through plugs a wee bit quicker.

what i am most interested in w/ those heaters is if you can scavange the exhaust heat, i thought about running the exhaust trough a longer section of pipe that coils inside a drum filled w/ water, or having the exhaust feed into a large heat exchanger like a normal radiator you would normally have in a house when you have hot water heating would love to see those ideas tested as i sadly lack the tools or space to do such experiments

Mine has four small vents on the front with ample vent pipe to cut and I have pointed the air flow in different directions with one pipe bent round and pointed on the hot exhaust underneath. I have also mounted my unit slightly higher and extended the exhaust giving me more hot pipe inside with the air blowing over it. The only negative is it's noisy on full chat. Good video.

[@bigduphusaj162]

Yeah I used to fit them on Lorries and Boats, im a boat builder now. You can use extended exhausts, burner intakes and exchange intakes and outs but if you introduce too many bends in them you need to go into the fueling and fan settings and modify them so it's burning closer to 14:1 again. It's not difficult to do but if you are fitting the genuine ones on a boat then everything has long runs on it. On boats and just as a mod to get them running really good you need to replace the fuel tubing with the rigid type and run them into proper rubber hoses with clamps just as they leave each connector. They make cheapo copy kits of the boat fuelling hoses and I've been told they work fine. Watch what fuel filter you buy as they are known to disintegrate cheap filters and never lengthen the controller panel wiring without figuring our the wire resistances first as that can cause all sorts of issues. See if you are using nasty biofuels or garbage diesel run them flat out for a few mins before you turn them off as it saves your heater plug and keeps them clean. Using a mains power supply for them will always be a timebomb because if you get any sort of power cut or spike it will instantly turn off without the shutdown cooling sequence and it will burn out the inner PCB and the internal wiring on these cheap ones. The genuine ones can take about 5 or 6 hard shutdowns. Cheers.

[@tejpor]

One thing must not be forgotten when you want to extract heat from the exhaust gas: if it cools down to 100 °C, the water vapor can condense and mix with the carbon dioxide to form carbonic acid. The condensation boiler is also created (the flue gas is cooled to 75-80°C), which is why it is made of acid-resistant material (preferably). If you still want to extract heat and do not want to install another heat exchanger, then the temperature of the flue gas must not go below 120°C under any circumstances.

[@josephm8292]

[@iguanamoat]

Just an important safety note. As it is set up right now, the exhaust is leaking carbon monoxide into your workshop. The metal heater outlet, hose clamped to the metal exhaust, is not creating a good seal. If your heater is not properly tuned (most of these are not, out of the box - ideally, they should be custom-tuned for your specific intake/exhaust setup and elevation) you will probably soon notice soot stains coming out of the gap as evidence of the leak. While the leak probably isn't huge, and these heaters normally don't produce huge amounts of CO, this can still kill you. These heaters can also produce huge amounts of CO if anything goes slightly wrong, for instance a partially blocked intake or exhaust, bad fuel, sooting up from age, the tune being wrong for any one of the heater's power settings, etc. The air intake should also be outside, facing the same direction as the exhaust, to minimize the effect of the wind on burn efficiency, which can cause sooting, leading to CO, etc. etc. I recommend sealing the exhaust connection with the highest temp automotive silicone you can find; I use Permatex 81878 and it has held up well, though I reseal it every couple years as the exhaust temps are right at the limit of what it can handle, and silicone will degrade with heat over time regardless.

[@PonziZombieKiller]

[@gustav901]

Well presented. One thing to note regarding your calculation for "how much more efficient it is than electric" compares direct heating (which I know is popular in Brittan). The latest generation heat pumps have SCOP above 6, meaning every kW in equals 6kW heat out. The upfront investment is of course on different levels, but with pre 2022 prices the heat pump will have lower running costs. Add factors such as interest on loans and it gets kind of messy but it's kind of amazing how efficient latest generation heat pumps have gotten. (For anyone looking up "what heat pump has SCOP>6" there's the Thermia Atlas that I know of)

[@darekmistrz4364]

What is worth noting is that heat pump "steals" heat from one spot to other using some form of agent. Usually it's RA134a and RA134a has a boiling point of -26 degrees. This is important because it means that heat pump cannot "generate" more heat if it's input side is lower than -26 degrees. It's very probable for air operated heat pumps for that to happen, it happens much less often with ground heat pumps. Also the closer to -26 degrees you get, the less efficient heat pump is. Heat pump with SCOP above 6 will not have SCOP above 6 if input is below -20 degrees. Some heat pumps have resistive heater built in as fallback to -26 degrees limitation

[@stompyrobutts]

Hi, thanks for video, here is some things you might think about: - Intake of burner must be taken from outside, as you let out other tube. now you are venting heated air to outside, its not a big deal, but when -20c and want to run quietly... - thermometer is not so good on controller, but you can use to "set" certain temp. - 5.5hz is 5kw heater. 5,8kw units are the same. - you can calculate consumption via pump hertz to get more consum information if needed :) - running on lower setting will have ALOT less consumption of power, you can use your 13.8v ac adaptor (if you use a small lead acid battery in pararell for igniting) Here on finland electricity prices is about the same, abit more. like 30-60cents/kwh in euro total atm, and there will be alot problems of poor people paying bills as we need heat long time, as we are on north.

One very important note. Normally, homes are heated not with resistive heating elements but with heat pumps that use the vapor compression cycle. These typically operate at a coefficient of performance of between 2 and 5. This refers to the energy required to move a quantity of heat between two points. For example, a heat pump operating at a COP of 5 would only require 200 watts to move 1,000 watts of heat from the outside environment to the inside. Heat pumps are also used to cool by operating in reverse. It's important to consider the efficiency of heat pumps when doing this kind of comparison. Still looks like a good product given the outrageous energy costs in Europe.

So you can heat your house with a COP of 3-5 depending on the groundwater temperature and on how much you can cool it down. Also right now the industry is adapting the concept due to the high prices for natural gas. A 20 Megawatt heat pump (7 MW electrical power) is currently beeing build which will use the water of the rhine river as a heat exchange source. So the concept goes a long way with applications for BASF as well since they need a lot of Steam and Natural gas steam reformation got a lot more expensive lately.

The cost of heating this year is sky high. My neighbour usually uses coal to power their boiler, last year it was £400 per ton, this year it is over £800 per ton. We are out in the countryside, so no natural gas. I use LPG for my central heating, the price of which is probably about 20% dearer this year than last year, which is not too bad when you consider just how much other fuels have increased. My workshop is in a big barn, so not really practical to heat it in the winter, but if I had a smaller space I would certainly consider one of these type of heaters, not too bad at all for the price.

[@DellAnderson]

Excellent Vevor heater demo video. Heartily recommend buying separate heater for safety reasons, not the All-in-one, because you can mount the heater sideways (glow plug up) and exhaust directly thru the wall. This eliminates the theoretical risk of CO (Carbon Monoxide) leak from the flex exhaust line, which in these type of kits is not necessarily the best, nor is the clamp fit perfect. Of course, CO can still leak around the orange glow plug silicone cover, but one less thing to worry about.

I just had my identical unit delivered about 2 weeks ago - it's been fantastic so far! I still need to pipe the exhaust outdoors, so I've only been doing short test runs (my shop is 26*62*12ft so my interior air volume... well... it's a lot!). But instead of having my natural gas furnaces going, I suspect this will be HUGELY cheaper to run, especially using my waste oil (my next experiment is to 50/50 it with diesel which is about $2/L here). For my exhaust, I'm going to use a trick we do/did in the generator biz - You drill a hole and shove a ~3" pipe through the wall. Then stick your much smaller exhaust through the large pipe. 3 machine screws 120* apart go through the walls of the larger pipe (drilled and tapped) at each end, so the tips of them just contact (not penetrate) your small pipe. After you're all done, pack the hole around the small pipe with Roxul (or another fire resistant insulation). It's super cheap, and works great.

Duct the air intake past the exhaust hose. So the intake air is warmed up by the exhaust tubing. Then you can lower the exhaust temperature, and also lower the pump speed frequency to save some startup power. Most of the 150W startup power probably goes to the glow plug, which is unnecessary. Once a flame exists, it doesn't need the glow plug anymore, so the device probably could just focus the first ten or twenty seconds warming up the plug at 60w instead, before turning on the fan. Something the company can still fix. (Together with harvesting exhaust tubing temperatures as air intake). They should find a way to pump the fuel using the fuel itself, and prime the machine using gravity only. I'm sure some sort of diesel engine like a sterling engine design, can be used to rotate the fan, which blows air over the intercooler part, as well as provide the interior combustion chamber with air. Aside from the initial startup, which could be done with a mechanical crankarm, I see no reason why a device like this should use any electricity whatsoever.

I too have a number of Vevor products and would have no problem recommending them, generally speaking cheap Chinese junk today has become cheap Chinese products, everyone will tell of a disaster but no one mentions the many happy customers. The lower prices also makes many tools available to the average person which would have been cost prohibitive, can only be good😊.

Dude, just stumbled upon you and you are awesome! I've been looking at these heaters for a couple of years now for my remote cabin and now I think I will pull the trigger. Way more efficient than the propane burners I run at the moment when my wood stove dies out at night. You have another subscriber here!

Thank you so much, do check out the latest video. cheers J

These type heaters were used on Trojan Earth moving equipment 30 years ago . These units are more like a 3 kw unit as they were used to heat the cabs ( which are the size of the drivers seat of your car ) in the winter .

I've got one in my home, and it warms just fine for several years now. It is connected to my own solar system, with 12volt traction battery, so the power supply is also free. To clean you can sometimes use petroleum, that cleans the system. When friends or strangers come, they find it a super idea 😊

[@s1dew1nd3r4]

does it not kill the battery quick time though? i wouldnt have thought it can run on on a 12v battery without killing it fast?

@@s1dew1nd3r4 Mine runs on a 100 amp hour lithium LFP battery box with a built in 6 amp charger. The watts needed to run vary with the heat setting as the pump and fans turn faster with higher heat output. I see 19 watts to 48 watts when I run H2 to H6 heat settings. But the startup and shutdown sequences use a lot more power temporarily as it heats the glow plug for a while. Maybe 130 watts for a minute or 2.

Great video mate. I've installed a few of these heaters on canal boats and my customers are very happy with the results.

Canal boats are the best

I brought one similar to this on eBay for £89 I used it all last winter to heat my un insulated workshop it goes from 5 degrees up to 15 in about an hour and then I put on lower setting to just keep some heat kicking in, sometimes I have it running all day no issues. Exhaust cored through the wall and sealed up with plumbers 1200 degree silicone. I have a digital carbon monoxide meter and it just kicks 3ppm out of the fan on initial start up but it goes in seconds and my monoxide alarm has never gone off! I’m also still alive 🎉🎉

I have a good industrial CO unit (MSA) with the yellow and red beacons calibrated. These things warn at 60 ppm and red at 120 PPM. You are completely safe with anything under 20 PPM CO for any extended period of time. I used something similar to this heater made by a german company back in the day because we were poor when the kids were little and run around 4 to 5 PPM consistently. I worked for the gas detection company so I fixed myself up a used unit for home that was more reliable. I know this CO business well. You are good at 2 3 4 5 PPM for any extended period. You need to be concerned about 60 or more on an immediate basis. 1200 will make you sick... so 120 is very conservative. Blast furnace gas is more than 50% CO.

Space permitting you could run the exhaust through a drum half loaded with rocks and then outside through a larger pipe. This would keep the back pressure to a minimum and the stones would radiate heat for a long time even if the heater is off. Also, I would use a battery with a 5 amp charger rather than using an inverter. That would end up being an automatic battery backup.

[@rontaylor3403]

I'm glad you said that , I was going to suggest that he use some type of heat exchanger to capture all that waste heat from the exhaust.

I have 3 of them and I love the dependability. It's ashame diesel is too high. I need to bring the air intake indoors to see if that will use less fuel. As it is in the winter, I burn a gallon every 24hrs. $4.50 a gallon.

I buy Kerosene in bulk for just £0.60 per litre last time and I got 1000 litres. My house runs on keep anyway so I just siphon some for the workshop. Cheers J
