How to tune a Chinese diesel heater with no tools 2kW & 5kW

[@mobiusx8117]

Thanks for the helpful video! It seems that to keep the combustion chamber as clean as possible, you would want to have combustion on the lean side and also maximize your combustion chamber temperature. So, it seems that you want to lower the fuel pump speed (which you have done) to lean-out combustion, but also *lower* the fan speed to increase the temperature of the combustion chamber. Where is the flaw in my logic? I guess the fan controls more than the external (cooling) air, that runs over the exterior of the combustion unit to provide room heat, the fan must also provide the combustion chamber air as well?

[@FuckignRuby]

if I recall, these are NA, but feel free to correct me anyone that has one of these

[@fredfred2363]

Choke the combustion air input when at max fuelling like a regular oil boiler, to get the lowest volume of combustion product. That increases volumetric efficiency, increases heat exchanger temps while still keeping a lean burn👍🏻 Think of it the other way too... throwing in too much air simply blows all the hot gas straight out of the exhaust. You want to reduce exhaust gas temps to near condensing levels, while still maintaing a lean burn.

[@Vortecks]

@Mobius X You are 100% correct! I'm pinning your comment, it explains the video in words 😉

I was going to use a server power supply wot you think tony ???

[@yodab.at1746]

@@idaveuk any power supply that can provide 12-13 amps at 12v will work. It only pulls 10+ amps while the glow plug is on, after that the consumption drops to around 2 amps.

[@micg]

I've been getting endless e-08's and e-10's for 3 months since getting one of these last fall -- all indicators pointed to too much fuel, but all the internet experts suggested too much air in my fuel lines, bad wires etc. Working on these changed nothing. Last night I used your setting as a starting point, 3.8 hz and 5000 rpm for the high setting, and without any other change it just started up instantly! Thank you!

[@djgrazzy]

Do you have your pump on an angle 15⁰-35⁰? I just purchased a second hand campervan and suspected that was my issue and found my pump installed perfectly horizontal.

[@oojimmyflip]

Thats odd because the ecu inside the heater has a pre-programmed start up sequence, it is the same start up sequence for all of them and it is not adjustable so whatever setting you set for running in the special settings menu it will not affect the fan speed on start up whatever you do, just the running speed after start up, so your tinkering must have paid off initially maybe you cleared some air from the fuel lines? or cleaned out the atomiser hole next to the glow plug ?, something you did right, or maybe you just have a tempermental heater, I had one that didnt like starting, so I cut the length of the air intake hose in half straightened it and put an old piece of stocking on the end as a filter medium with an elastic band, it starts first time every time now. when you run one straight out of the box they will start up and run fine without any hoses or exhaust pipes attached and I thinkn thats how they test them in the factory. Then we go and stick a carboard hose on the air intake and restrict the airflow with a plastic silencer, probably slightly crushing the cardboard tube in the process or bending it more than once so that it struggles to get air to the combustion chamber.

[@micg]

@@oojimmyflip when I had it on default settings, it would start up the first time after install, then just smoke and pop like crazy on every subsequent attempt, over and over and over. Took everything apart, cleaned out the build-up (it wasn't burning the diesel fully), reassembled.. same thing. Double-checked literally everything, pump angle etc. was all fine. It was only once I re-did the settings as outlined here, found the sweet spot, haven't had an issue again. Didn't even have to disassemble and clean, just got going once the settings were fixed after many failed ignitions and a few flame outs on the default. Last night was the first time I had it on since May, still using the modded settings from last feb, and it fired up right away. I infer the startup sequence uses the 'low' and 'high' settings as its starting and ending point, gradually moving through the curve between these, if you think of it like a graph. Pretty sure its not just one default startup with static fan/fuel settings. If you think of the stoichiometry of the reaction here, diesel combustion needs diesel, oxygen, and heat. When the reaction isn't working right, its one of these three things that are off, can't be anything else -- in my case it was lacking sufficient oxygen for complete combustion of the given fuel amount. I think the issue is pump capacity. These kits all come with different pumps, ranging between 16-22ml per 1000 pumps. The default setting is maybe correct for one of these pump sizes, not the others. I can't remember which size I have, I think 22ml ie one of the larger ones hence me needing to get more oxygen in there per pump frequency.

[@bigduphusaj162]

​@@oojimmyflipThats wrong mate. I install these on boats im a boat builder. Lots of the smaller boats we do fefurbs on the customer wants the cheap chinese ones. The start up sequence will change with the max and min rpm settings because the algorythim reduces the speed in which the fan ramps up just as it turns the plug off. For example the ones sold as 5-8kw are known for if you set the fan speed at 2500 & 5000 they have a habit of blowing out right as the plug turns off and the fan ramps up to max during start. The ramp up is too fast and the chamber usually gets blown out around the 56deg mark then you get a shutdown followed by an automatic second attempt, which sometimes gets it going. By lowering the max fan speed to 4400-4600 regardless of the fueling frequency you will automatically reduce the ramping up speed and the heater will no longer blow out at 55ish deg when the plug goes out. You can clearly hear the difference it makes and if you have anything monitoring your battery then you can see it the figure on the fan rpm ramp up spike is lower on startup. This goes for the black, blue red and newer black controller the one that has the voice speaker and connectivity. This is also the case with both aftermarket controllers ive used and the algorithms in the expensive aftermarket one (you know the one?) its automatic start up sequence is basically 4800 normal temp start up, below 0 deg intake it goes to 4600 max and on second attempt onwards the controller sets the startup speed to 5000 for the 5-8kw copy heaters. I hope you accept this as the truth because ive had to sort a load of them for the same issue especially after plug changes some dont like set to 5000 on startup because of the ramp up being so steep. cheers.

[@bigduphusaj162]

​​@@micgyou are right sort of. These heaters especially the 5-8kw sold models the start up sequence algorythim will vary based on the max-min fan speed rpm, mostly the high speed setting. During the start up sequence the distinct ramp up in fan speed that coincides with the heater plug going out (around 55deg) is because the heater thinks the chamber is lit enough to run on its own. If you set the top RPM speed to 5000 and your heater runs fine then cool but if you are suffering blow outs on start up then reducing the max fan speed to 4600-4800rpm the rate in which the fan ramps up at slows so the chamber doesnt get blown out. Some of them you cannot get them going on 5000rpm setting after a plug renewal and a clean, they need backed off to 4600 to 4800 for a good 50hr before they can be sped up again. Despite what people think about these they run best with a small amount of carbon built up especially around the inner chamber where the gauze is around the turbulance plate at the bottom of the atomiser. When you clean them fully or use them from new for the first time this is why they dont burn right for about 50hr. They dont like too much carbon build up but nor do they like none. Webasto and Eberspacher know this btw thats why they have a cleaning setting now on the boats and lorries. The cleaning setting purposely gives it a rich wet burn cycle for 8 mins then roasts the thing for 3 mins then roasts it again for one minute then shuts off and restarts then sits exacly half way for 5 mins on the next start up. Hope this helps Edit: I forgot to point out on this reply that when you put the heater in a "cleaning" cycle on the newer models in lorries and boats it automatically runs the high speed fan at a heavily reduced rpm as it takes into account that you might be doing the clean cycle because it has a choppy start up. Interestingly what it does is turn the plug out at the usual temp in the start up cycle but there is a delay from them about 20 seconds before it soft ramps the fan RPM up to max.

[@darrien28]

Oh My Goodness! I have been hunting for MONTHS about how to stop my one of these, from fouling. I'm no mechanic, but I suspected there was a relationship between the hertz and the fan speed that was causing my issue. This is the first resource that I've found that showed a logical, simple, approach to sort the tuning...that anyone could do with a spare half hour or so. So - THANK YOU VERY MUCH! :D :D :D :D

[@gordonmitchell729]

I have watched your video and followed along for my heater. With the minimum fan from 1,500 to 2.500 and the maximum at 5,000 rpm, I adjusted my low hz to 1.2 and the high hz down from 5,5 to 3.6 when I got the 2 red bars back. All appears to be okay, so I will see how it goes for a while. Many thanks for doing this video.

From what I've read, I'd be careful running the fan at 5k. 4500 is as high as I have mine set

@@CharredSteak good advice thank you. I have reduced the speed and it’s working better.

Thanks Cliff, I'm glad I could be of help. Properly tuned, these will run for a couple of years before the motor needs replacing when the brushes wear out. When I say a couple of years, I run mine probably 16 hours a day from the end of November to the end of March which is over 3,800 hours. I'll cover the installation in the next video and the servicing in the one after that.

Thanks Tony, loving mine, will definitely have a play with its settings now. Intrigued with your fuel pump upgrade, I have mine hanging on some string which has dulled down the harsh clicking 100%

[@oojimmyflip]

built a box around my pump with 6mm plywood with a hole top and bottom for the fuel lines and wiring to go through, then I used 4 cup hooks to hang the box on 6mm bungee chord attached to 4 more cup hooks on the roof of the wall mounting box, cannot hear the pump clicking inside the wall box mounted to my outside wall of my house or indoors. my hearing is so sharp I can hear a pin drop outside at night. I have to sleep with earplugs in and I still wake up if I hear a noise outside through the earplugs. The pump is silent.

[@julias-shed]

That’s pretty good explanation of how to tune it. My 5kw is on a max of 3.3 at the moment as my fan speed is 4600 max I didn’t think they liked 5000 but it sounds like yours has lasted okay so might push it higher. I’ve had terrible carbon in mine but its getting better now the mixture is leaner. Thanks for the video.

[@Vortecks]

They will all go to 5000rpm but different manufacturers have different default values that get them all running in the test room. Different altitudes and air conditions need different air/fuel mixtures so the manufacturer of yours might have been at a different altitude or in a vacuum 😁 My suggestion is, strip it down and clean it. I will be doing a video on it, it's not hard.

[@julias-shed]

@@Vortecks I have just cleaned it. As I said it's getting better as the mixture is leaned out. It did start off as an 8kw with the usual over the top settings so it's taken a while to get it to a decent setup. I wish I'd seen your video a year ago it would have saved a lot of stress 😀

[@Dirt-Diggler]

@@julias-shed that's another issue with Chinese knock offs, they lie ! There is not or ever has been an 8 KW 😏 these are copies of the eber 2KW and 5KW heaters, the Chinese fall into the group who think more fuel equals more heat, 8KW is just a 5KW run at a higher pump dose rate and "sometimes" a higher fan speed, this either soots up or the fan bearings go, usually because the brush end bearing gets full of brush dust due to the motor overspending and prematurely wearing out the brushes 👍

[@Vortecks]

@@Dirt-Diggler Some mainboards & LCDs allow a fan speed of 5500 RPM with an increased pump speed. I might be wrong, but I think these are the ones marketed as the 8kW version. Last year, I tested a 5kW which goes to 5500 RPM and it will just about hold combustion at 5500 RPM and 5.3hz. The only trouble is, some of the combustion happens outside the flame tube and goes directly into the exhaust and the exhaust was hitting 280C. It 'might' be the equivalent of 8kW in total but there's probably 3kW which is directly pumped into the exhaust. Very dangerous.

[@bigduphusaj162]

they dont like 5000 none of them do. The 5000 is only for a badly made machine. The startup sequence rpm ramp speed on 5000 runs them to lean full stop. From the 55deg mark when the plug extinguishes and it ramps up the fan speed to max because it thinks its lit, you are merely running lean as the air in the AFR spikes massively. This has been proven by countless people with proper measuring devices. The 5000 setting automatically sets the start up algorythim to ramp the the fan up quicker than it does on any other setting so its not just the max rpm effected. Anyone whos heater can run on 5000 no problem still wants to back it off a bit as it saves the plugs. i can get boats doing 3-5yr on these cheap copies and 5-7yr on the original plug on the genuine ones and i diall the smoke and smell out of them within minutes.

[@rusty911s2]

I've just installed one of these and will tune as you suggest, thank you. Mine's in a large workshop so space not massive issue so my next step is to try playing with exhaust heat exchanging. I appreciate that whatever I do can't create any more back-pressure than the supplied exhaust tubing, but my thought / hope is that extracting heat from the exhaust will drop pressure if anything (it's effectively a charge intercooler) whilst enabling the harvest of some waste exhaust heat.

[@Vortecks]

Yes, using the exhaust as a heat exchanger is something I want to improve although I think I've got as much as I can out of it. I'm using 32mm (I think) copper tubing which I had to silver solder together. As long as you tune the heater again after you've connected it, you'll be fine. Mine inevitably does produce a small amount of back pressure but it's been running for over 12 months like that and zero build-up.

[@rusty911s2]

@@Vortecks Interesting, have you got that on a YT Vid? Would love to see what you've done. I've got a few ideas but annoyingly only thought about doing something after the heater was installed, so although I have options, they're not unlimited.

So glad to have found this video. I have been wondering about fine tuning these units. I use one to keep my bedroom nice and warm but I have noticed it really goes through a lot of fuel on high and this video has shown me that I can really reduce my consumption and get the same heat and even better air flow in the room.

[@wrxs1781]

After running my heater all winter on factory setting, I get great results, make sure the exhaust is in a downward slant, this is where the carbon or soot buildup starts. And the most important thing is "leave it alone so you don't burn your house down"

I'm glad to see that someone was able to make good use of theses heaters and taken the time to tune it as I've seen several of them fail (Julian Illiet had one fail)

It does take some thinking about but they're just an engine that relies on air and fuel. Being an ex car mechanic helped understand where it was going wrong. I've wanted to shout at Julian when I saw the smoke coming from his, I get zero smoke on startup or shutdown.

[@Dirt-Diggler]

At last someone who understands AFR ! Appart from davidmcluckie and john mck 47 your the only YTer who even starts to understand it, soo many 5min experts out there 🙄 The original webasto and ebers didn't allow owners to sod about with pump speed and fan speed, they were set at the factory to give heat with a low ex emissions, something the Chinese dont really care about all that much. 90% of issues i fix are sooting up because owners fiddle with the settings or the base settings are way off, the older blue controller would let you set dose rate up to 8Htz with a max fan speed of 5500 rpm, some would only allow 5.6htz at the same rpm so no wonder they get messed up and sooty 🙄 after a clean out i reset the controller and tell owners to use the temp settings and stop messing with the dose rate 😏 or buy a decent make, webasto and eber obv, mikuni are ok, autotherm/plannar or the lavana pro series 👍 Really enjoyed that vid chap 👍 looking forward to a few more on the subject from ya 😎

[@Vortecks]

Yeah, I noticed that there are a lot of people who just want to jump on the bandwagon to get a video published, it was pissing me off that there's not much info on how to use them properly so I decided to start the series. There are a lot of bad tips on how to use them and very little in the way of safety. I wish I could find the video where someone said to go into the settings, max everything out and it runs much hotter 😒 I've got every controller & mainboard there is out there now, I kept buying them from China. I was considering buying the afterburner buy it seemed like a lot of money for loads of features I wouldn't use so....... I built my own. If you go to 8:14 you can see the TX part of it on the right but I'll cover that in another video 😉

@@Vortecks I've gone the total opposite from the afterburner in that all i have is an on off switch with remote activation and a normal 2 wire stat in the van but my own build is a rather old mikuni i saved and refurbished from a narrow boat who changed it for a cheap Chinese unit cos it was £15 cheaper than servicing the heater he already owned 🙄 his loss my gain 😎 i got paid to change in the new unit and got to keep the old one, i removed a webasto from my van and use that for back up heat in winter at home 👍

[@FuttBuckerByMutt]

What I’ve noticed with the heater is the intake “filter” is tiny. As a gear head and diesel mechanic I’d imagine that filter may be restricting the air which could cause excessive soot or carbon build up. I modified mine and it appears to run significantly better at its highest temperature setting

[@lookinin123]

I love the tinkering and tweaking of this heater. I wonder if you were able to get the dose rate so low because you're closer to sea level. I'm over a 1000' ASL and I can't go any lower than 4.5 Ghz. Of course, the incoming air temperature might have an effect on the heat exchanger, too. Thanks for taking the time to post this. 👍

[@Vortecks]

Yes, there are a lot of factors which mean you have a high pump rate - barometric air pressure, air temperature, the location of your pump in relation to the heater (some people have it 3-4ft below) blocked fuel filter, water/condensation in the fuel or very high humidity. FYI I'm 500' ASL where I am. Obviously, very cold temperatures makes diesel freeze or at least 'gum up' if the tank is outside.

[@bigduphusaj162]

dont go too low AFR as they go through plugs. Regardless of fan speed if you dont run enough fuel through them they burn plugs up and the mesh doesn't last long. If its running ideal AFR wise you will be able to run the heater at a lower normal main menu Hz setting as it will be kicking out more heat for each normal heat Hz setting so you need to undertand that leaning out AFR doeant always equate to less fuel used per heat unit kicked out.

[@alibro7512]

Its great that there is even a function in the controls to adjust the unit for best results. Great info, thanks. Subbed. I live in Australia, and my retail natural gas costs AUD $20 per kw/hr of heat. Diesel is AUD $2.00 per liter and makes 12 kw/hr of heat........there is no comparison.

[@mathewemy]

Might want to look at your math. MJ in Vic is 3.52c and supply charge .83c per day. Diesel is around $2 so .0352 X 38 is $1.33. QLD at .06 is $2.28 but who needs much heating up there.

[@wazza33racer]

@@mathewemy I did the math........converted the joules into watts etc. The thing that bumps it up a lot, is the supply charge. For a typical residential user with relatively low volume of gas, the fixed supply charge really ups the overall cost per kw/hr of heat. There are no options to avoid that supply charge other than to have the service disconnected. Furthermore, as natural gas is gobbled up by the expanding number of gas turbines being used to supplement renewables during night time and especially wind droughts.....the price is only going to go up, and up and up. Gas turbines are horribly inefficient at replacing natural gas as a heat source in heating applications........they need to burn 3 times as much to provide the same heat energy............but since they are paying a tiny fraction of the price, they dont care about the waste of energy.

With very careful planning, it's very quiet in comparison. There are 4 sources of noise: The inlet, exhaust, heat outlet and the fan motor. I'll go through all of them when I can get my head around explaining it.

i bought one recently and the ability to tune simply isn't in the controller, apparently there was a shortage of the above type controller, mine has a spanner icon instead of the cog wheel icon... not sure if that is the difference but probably be best to avoid the spanner version... i imagine the ore expensive heaters will still have this ability...

@@timkelly5602 I changed all my ecus and controllers to the Blue controllers with the led remote controls they are easy to use and give you readings of the core temperature and voltage on the remote fobs screen. they have a range of about 30 feet and use less complicated and cheaper tripple A batteries which last about a year. The blue controller has a matching Blue motherboard/ecu for the Heater and it is identifiyable by the silver Bi-metalic strip that crosses the blue coloured circuit board from one side to the other.

[@bigduphusaj162]

they can be made very economical especially running two or muliples at a lower setting like in boats. Im a boat builder ive done hundreads of the genuine ones and maybe 30 to 40 chinese copies. I like the guy in the vid but i dont think his figures are correct and i think his heater has burned its mesh on the inside of the burner out to the point it runs at settings it shouldnt. Absolutely NO way is any fully working 5 or 8kw branded copy heater running at AFR menu 1.2hz and 2500rpm. You will instantly hit sub 110deg on any fully functioning heater even at 1.6hz if you go over about 2000rpm on the slow fan speed setting. You do need to up the stock 1500rpm speed by about 200rpm to get it running good if you extend ducting and exhausts to the limit but to gave a heater run at 2000rpm and 1.2Hz means its mesh is gone and atomiser is cheap junk. Ive no idea how hes got it to stay above 100deg burner temp at 2500 low 1.2.

[@tommyp1124]

I run mine on 0.8Hz and 1500RPM. It shows only 1 red bar or no red bar at all when it's below 0*C but never had any issue with carbon buildup. However running at around 3Hz or above without adjusting max Hz did indeed extinguished the heater and made impossible to reignite. Fortunately I was able to make it run again by blowing some air with industrial vacuum cleaner thru exhaust pipe and them pull the air when the heater was trying to ignite.

Why don't you try running it on Paraffin Tony...?..Back in 1962, they were all the rage.. Paraffin is a purified form of Diesel. Way cleaner. Esso Blue anyone?...I can remember Pink Paraffin also....Just a wick and mesh burner. No blowers or fans, just gravity fed paraffin...😳😳😮😮😏😏🇬🇧

Could even be worth trying different fuels anyway to see what's the cleanest and most efficient between waste oil, kerosene, parafin, diesel, JET-A1 and so on... or if a blend of fuels / fuel oils is better....

[@EnglishTurbines]

@@DigBipper188 I can tell you the answer. Kerosine (Paraffin) has the highest calorific value of all of them. This is why it's used in Gas Turbine engines...Jet Petrol or Jet A1is very refined Kerosine with the sodium removed. Plain Paraffin is the obvious fuel for this heater...It may be a bit more expensive than Diesel though...🤔😳😳🇬🇧

@@EnglishTurbines Many years ago we used straight diesel to fuel 8 Rolls Royce Avons running through English Electric power turbines to EE hydrogen cooled alternators with SSS clutches to enable synchronous compensation.

if you mix kerosene into your diesel, it will burn cleaner and clean out. also if you do one tank with some heat or high octane additive. that will also help clean out and burn a bit hotter. Also when tuning, other things to keep in mind is elevation and outside temp... I was in -20 the other day and it wont keep up if the fan keeps it too cold.

[@stevecarlisle3323]

I run 5 CDH heaters, and all heaters have run very well, producing lots of heat at all settings. Any setting under 3 will produce sooting, and eventual failure to ignite. Looking at your burn chamber, I would guess it has been run at the lower end of the fuel setting.

[@rossallen738]

Mine had been running great for quite awhile. Then we got some extreme temperatures and I think the gummed up diesel clogged some things. I cleaned everything out the best way I knew how. Finally got it to start again. It ran for a few days. Woke up this morning to a chilly home. Noticed the diesel heater had stopped working again. I pulled it all apart, cleaned it up and it fired up immediately. Thought all was well, but then I noticed the combustion chamber temperature was steadily dropping 2 Celsius (from 176 ish) every 10 minutes. I finally turned it off at 138 C and took it apart again. It has just as much soot as it did over the few days that it has been running since I cleaned it last. Prior to that one temperature drop, it had been running near mint. No carbon buildup to be seen.... I'm currently lost as to what is wrong. I have no idea why it's suddenly plaguing me with issues now...

[@bigduphusaj162]

Hi mate i apreciate you doing a vid as im looking for one i can send about to show whats going on. However, you make far too many mistakes for anyone to take this as gospel. Firstly i agree if you are running extra exhaust sections and longer ducting then it will especially need the low speed side of things. However coming down from an ideal contoller AFR setting menu from 1.6 to 1.2Hz on the fueling alone is dodgy nevermind running the fans at 2500 to keep the thing in the 130 deg burner temp zone. Thats a junk machine if you can get they settings to run. Other issue is your recommendations for max rpm max HZ and general confusion. As a boat builder thats done hundreads of these now and at least 30 or so chinese copies the basics are this. A 5kw is the same as the 8kw burner, pcb & plug wise. The ones sold as 5kw didnt quite make the grade as the 8kw that would run on the controller set to 5.5 and 4800-5000rpm. The 5kw copy ones were the identical heater only they couldnt get them started or running good at 5.5hz and 4800-5000rpm so they got binned in the 5kw bin. Now the tricky bit is it could just be the quality of the plug installed from new or on a plug change that would mean your heater sold as a 8kw that ran no sweat at 5.5 would barely run at 4.5-5hz just because of a plug change. Now if your plug & atomiser on the refit is lesser quality they will need to be set at the settings you described in the this vid. The very settings that would signify poor quality plug and atomiser mesh. The further you need to deviate from 5.5hz and 4800rpm on the 5&8kw burner models then the poorer the plug and poorer made your machine is. Even with a long exhaust and intake run 2500rpm at even the higher 1.6hz stock setting would signify you have mesh issues and the burner is toast. You should not be able to run anything on these bigger bodied 5&8kw heaters at 2500rpm on the low setting, that should instantly cool and have the burner down at 100deg barely one red bar. Theres something off with your figures or your heater mate so for that reason i dont think this vid is trustworthy at all for a begginer eapecially. These are easy to tune you made it sound hard. If you can get the low hz and rpm to 1.5-1.7hz and have the fan low set to 1500-1700 then you are dialled and expect 120-130deg burner temps. Do that then set the high speed so the burner temp will reach a minimum of 165deg with the Hz set between 4.4 and 5.8max and 4600-5000 rpm. Anything outside these ranges WILL affect plug life and carbon build up and bearings. Cheers.

I have a 5kw version and I haven't had issues with it sooting up or smoking. The mixture is about right. After last season there was little build up and it wasn't black more grey. My fuel tank is about 4ft below the unit and it makes me wonder if the height you draw the fuel affects fueling. I already know that if your tank is above the pump it does flood through. Or maybe I was just lucky.

[@Vortecks]

Yes, having the pump lower down reduces fuel delivery. If you put the pump any higher, you'll probably find that it starts choking it. I think you were lucky with the placement of everything, so don't change a thing 😁

[@dr_jaymz]

@@Vortecks I screwed it to the wall so it isn't going anywhere - but I think its the fuel head height that matters. The other thing that can affect it is any changes to the inlet and exhaust circuit. So for example, adding a different silencer or changing the pipe length may reduce the air mass and make it over rich. But also as the combustion chamber soot's up it may also cause it to over fuel and I bet that will be a positive feedback of doom. As they have no mixture control they probably should be set up to be quite lean. I saw someone using a lambda probe to get 15:1 at which point it smokes - I think it should be closer to 20:1, I think that 15:1 only really applies to fixed volume combustion like a cylinder than a flame in a tube where you will have an excess of oxygen.

[@dr_jaymz]

@@Vortecks What I could do is get one of those pumps and pump the fuel 1ft uphill and then 6ft uphill and measure the fuel delivered in 10 mins say.

Also 5kw heater, Ive read before 3.6-3.8 hz is most efficient in other videos, i also tested it out it saves fuel and theres a very slight black smoke i see out of chimney when u got it at 5-5.5hz. I just almost got mad now from fuel pump noises. Theres also a very good method of tuning when u buy some cheap chinese co meter and if you put it at high you see like 10k ppm and at low 1000 ppm and when its arround 3.6 hz you get 400 ppm...

Great video. Excellent advice about the settings. Give or take a few factors, those are good presents. I find that mine requires a little adjusting throughout the heating season. Cow tipping high winds and barometric pressure and every now and again the fuel isn't what it should be. Mine is running 24/7 until spring. Every 30 hrs I'll turn it all the way up for 20-30 minutes and then back to whatever setting is comfortable. Make it a habit to continually remind the sheeple about safety and good old fashion common sense. Otherwise, we all know what happened to other great products that got into the hands of the clueless. Thank you for sharing .

[@Vortecks]

Yes, barometric pressure is the possible cause of 90% of the sooting. The manufacturers set a default value which makes them run in their location but that setting doesn't work for most people.

Now works a charm and havn't needed to clean it since, even running at low speeds all day.

Wondering if the temperature sensor is the main or only sensor I would need to move or “fool” to achieve this unit essentially regulating a fire that’s not contained in the unit. I know this is crazy talk but I’ve pondered it a while and I’m a bit of a fabricator. Any thoughts on possible error codes or problems I would come across that would shut the unit down. Thanks

[@davidfaulkner6008]

found how to reset the PIN....see reply in my original question having played with the settings (5kW heater) I found that, at 4500 RPM the heat gain across the heater is as follows...at 5Hz it is 47 deg C (7 in, 54 out), at 6Hz it is 66 deg C (7 in, 73 out), at 7Hz it is 75 deg C (7 in, 82 out)....I stopped at this point for fear of overheating anything 🤔 Below 4.5 it drops one bar on the display as per the original video.....but increasing that to, say 4.6 although returning the bar on the display and then increasing a further 0.2 as per the video seems to make a dramatic difference to the outlet air temp. which increases as more fuel is added......kind of as expected but up to what point ? so, how does one determine the optimum setting for heat gain across the heater?... presumably - and I dont have a CO meter - the CO will increase as the amount of fuel increases although even at 7Hz there was no visible smoke and no noticeable smell I should add that I am running it on normal domestic heating oil (kerosene)

I recently got a 2kW that would flame out after 10 minutes and never got out of the yellow heat bars. The fan upper setting was 4500 and the pump 4.6Hz. It wouldn't stay burning until I had upped the pump to 6.4Hz which seems quite high for the kW rating. But anything less and it won't keep at 2 red bars. I haven't yet upped the bottom end settings but it appears that the chamber temperature should stay in the red bars? or is it normal to reduce speed and drop down to the yellow? I suppose there must be a minimum temperature to sustain the flame. Before I sorted it out the vendor sent a replacement which wouldn't ignite at all and was factory set at 3.4 Hz and 4250 upper pump and fan speeds. Maybe the 2 kW is a less efficient burner that actually needs more fuel? Anyway, thanks very much for posting this it was very helpful in getting one of the units to run.
