You see we in Australia don't have any problems with the ticking noise a Chinese diesel heater pump make, it just sounds like the rythmic ticking of the electric fence units we use to keep the Salt Water Crocodiles away at night, and generally it sends us off to the land of Nodd in minutes.
@@13yearsaprepperr.jtilbury.51 My tinitus is louder than the pump, also if the cicadas are out making a gowdawful racket, you certainly dont need a heater.
greggy weggy, I'm reminded that Captain Hook is quite alarmed at the ticking sounds of a particular croc, and would not find any rest in such a fence. Poor devil.
I thank GOD I dont have to contend with the huge water lizards like ya do. I used a ticking electric fence to keep the coyotes out of a goat pen. Stay safe .
"Just ignore the smoke". I fng love this guy. Ive had one of these heaters for 5 years and I got tons of help from your videos. These heaters are improving a lot of people's quality of life and you're contributing to that. With all the b.s. out there...this is quality genuine non bias family friendly programing. Nicely done
I had one of the first prototypes of this silent diesel pump installed by the inventor himself and it's still working coming into the second winter of use.
Awesome vid on an awesome product. I bought one of the prototypes a few months back as James was just getting started, a complete gentleman to deal with. I run my 5kW workshop heaters on kerosene so between us we were able to prove his new pump internals stood up to both fuels and changing viscosities with temperature. Must have run at least 100 litres by the end of my testing so a thorough test IMHO - and a quiet one to boot ! Thanks for all the vids David, you've been a massive help to me in my workshop diesel hearter shenanigans.
Ok do you know the flash point of kero is considerably lower than diesel. 65 deg celcius. Diesel way over 100. For safety sake I'd stick with diesel. Good luck.
After a year with this pump it’s amazing no noise at all on the 2nd gen pump James does I still chat with him by email when setting new heaters up He’s a great guy the after sales he does are brilliant top man I have my pump in the garage of the motorhome so basically under the bed direct below the pillow lol no noise or ticking I only hear the heater on start up I can leave the heater on all night with temp settings to come on when temps drop I invested in a ignite challenger controller too so I can turn the heater on when I’m out brilliant
I saw one video where the guy screwed a cup hook into the wood above, then suspended the fuel pump using a tie wrap ( or some people call it a zip tie ) from the cup hook. The tie wrap went through the bracket mounting hole in the fuel pump. After that it was completely quiet. It was amazing!
From what i have ascertained from watching videos is that the pump needs to be at a particular angle to operate properly, if that's true or not, I have no idea.
My dog comes over and wags his tail at the start of your vids haha. Fascinating bits you find to talk about. I am very interested in someone's comment who suggested a simple PVC vacuum tube to muffle pump. Sounded silly at first but his idea was actually pretty good and worth more thinking for this problem.
@@DavidMcLuckie The idea is to place the original solenoid type pump into a short section of PVC pipe (say 50mm diameter) with a stop end on each end. Gland or seal the fuel lines in and out each end, do the same with the power cable. Drill another hole and fit a schrader valve (old valve stem from a wheel should do). Seal the whole thing up. Fit a vacuum pump to the valve and suck all the air out. Now you shouldn't be able to hear anything other than possibly noise transferred via the fuel lines. It should work well I expect. You might need some low density foam to help keep the pump centred away from the pipe walls. I thought overheating might be an issue but perhaps the fuel flow might be sufficient to cool it.
@@fionnut Good description. The comment that gave me the idea implied a fairly simple vacuum pump and described how he could hear the noise lessen as the pump slowly kicked in. It would only be a partial vacuum so I dont think heat dissipation would be a problem.
@@fionnut lol. bicycle valve will not hold a vacume as it is a one way valve that keeps air in and not out of the tire. so you must install the valve bacwards to make it work.. i would rather fill the pipe with insulating wool and be done with it.
@@vihreelinja4743 It's possible to use the type of valves used in air conditioning systems instead, these will definitely hold a vacuum and are still cheap. Insulation won't dampen the sound to nearly the same extent.
received my pump off james installed to day the new model is totally different to the one in the video must say they are a brilliant piece of kit totally worth the money
@@DavidMcLuckie very true i had to pump from the garage at the back of my motorhome to under the seating area which is just over 7mtr in length the pump took less than 1 minute to get the diesel to the heater was well impressed
Adding a mass to the standard pump is the best way to absorb and disperse the noise. I've tried a lot of different materials foam etc, and the heavier silicon sealant was the winner !
I will have one but give the poor chap time to catch up on the influx of orders lol. .....I can just see some chinese firm copying it but just don't buy them...this guy obviously talented and I'm willing to pay for that price, I hope others follow my suit.
One day I will have a camper van or a shack in the woods and when I do this will be the pump I will use with my Chinese diesel heater, I run a heater in my wee workshop and when I start it up that clicking pump pesters me and I could well imagine what it would be like if you was trying to get to sleep 🙉 that silent pump is a work of art and I bet the man making them is inundated with with orders , I do hope the man does very well out of this ingenious invention.
For myself and I suspect many others, it's a big job or not feasible to get this pump above their fuel tanks as most have their heaters, pumps and tanks close to their van floor. Very impressed with the quietness. Hopefully syphoning can be over come. 👍
@@DavidMcLuckie Thing is, I have everything under my sink. Heater bottom back, tank above (10lt) and the fuel pump bottom front as you stand at the sink. Area about 400x400mm. 🙄😳🙃
Hello I will eventually move my fuel tank below the pump and heater. For now, I’ve put a small 12v solenoid valve in the fuel line. It opens when heater is running. Like David I hadn’t read instructions so awoke next morning to quite a large pool of diesel on the road. As I burned off the excess in the heater the smoke was unbelievable for about 5 mins. Neighbours thought van was burning. Anyway great pump. No regrets,
Bought one last week and waiting to arrive. My normal pump is suspended underneath and is reasonably inaudible inside. I want it to be silent outside as well though. For those complaining about the price - it's a bespoke product handmade. It's not going to be as cheap as a Chinese factory made product like the diesel heaters, which are a bargain we can all agree. Compare to an eberspacher/webasto pump and suddenly it becomes cheap.
Just saw this on the foresty forest channel. He couldn't fit and test it as the ambient temperature was too high. He wants to see how it performs in -30c
Nice, although this seems a bit overkill to me. I found the best way to mount the pump is have it suspended by the fuel lines an inch back from the pump on either side so the pump itself is floating. That way the hose itself acts to isolate vibrations from the pump (works especially well with soft silicone hose). My pump is barely audible when properly isolated, it's the surface the pump is attached to acting like a speaker cone and amplifying the noise which is normally the issue.
Depending on how this pump housing is used the design is great or bad. I think. By that I mean that I think it is a very bad idea to have electronics underneath something that can leak on it. I would be more happy when the electronics would be above the pump and even have a devider screen in between in case something would spray out of the pump in case of a failure. And a small drain hole in the bottom so you would see the leak before it would destroy the electronics after filling the box.
I live with one 4 feet away and the ticking is actually kinda nice and comforting... though mine hangs on a couple of cable ties within a modified toolbox on the front deck so its like a quiet clock you have to actually try and hear.
I'm intending to build an insulated box outside my shed (workshop) to house all the Gubbins except the controller and the hot air outlet tubing so hopefully there will be little or no noise. Also removing the necessity to bring diesel into the shed. 👍 😎
Have you considered using noise/sound meters when you measure the volume of pumps or exhausts? At a pinch you could use one of the many apps available. That way you can do objective rather than subjective test which are way more valuable.
I doubt it, think how far whale noises travel, etc. water doesn't absorb sound much. You would probably have to make it submerging yourself too, not all pumps are insulated.
$37 oil pump a $5 arduino nano and a $5 FET driver if you want to build it yourself, don't know I like the idea of a re-manufactured pump I can't buy when the guy dies or gets bored
But the siphon happens with the flow of fuel. It'll siphon the entire fuel tank through the heater if you let it. A one way valve would not prevent this.
I think I need a spring loaded valve but with a very light spring pressure. Low enough not to impede the pumping of fuel but high enough to stop a siphon flow.
I’m guessing the lack of orange overalls means it’s the “other season” in Scotland (the season of midge rather than the season of pishing it down 😂😂😂) I married a Scot, so have some knowledge of such things - I’ve been there during both seasons 🤭 Amazing bit of kit; a beautiful example of “shed engineering” from James, for the same price as one of those “super quiet” pumps that isn’t.
Make a hole in the bottom. If diesel comes leaking out that housing, then you know something is wrong. Now it could probably fill up with diesel before you notice.
Interesting to hear / see the difference between the Webasto and China silencers. Just like that order on Webasto and the big one. In your case where it is so close to the ground and stationary. I think it would be interesting to see / hear the difference if you made a frame around the mufflers and filled it with sand. It will limit the sound output to only be the output itself and thus no resonance from the dampers. Best comparison for us watching, your test. Would be that you cut the video together so that each cut is the different combinations, without gaps. Then the difference will be easy to compare. Continue the good work. Thanks A Dane in Sweden.
What's wrong with the people selling this type of stuff, that they can't be bothered to setup a quick shopify store to automate everything? I can't imagine how many sales they lose by complicating the process through email.
I installed one in a VW Crafter camper and you could only hear the sound of air leaving the vents on full power. But some people only have the option of installing the fuel pump inside.
When General Motors car manufacturer came out with the 1988 Oldsmobile diesel engine for their cars they used a 350 gas engine and converted it to diesel. To get it to start faster on cold days they put in 6-volt glow plugs instead of the usual 12 volts glow plugs. I wonder if you could do the same and reduce the startup time and less amp draw saving on battery-operated power supplies like the Jaberwaky I think it's called.
I wonder about long term durability. Pull chord ICE motors have this type of mechanism (diaphragm run by vacuum) but they eventually age/give out. Not that your typical impeller type pump is immortal or anything.
I had the second prototype of this silent pump fitted by the inventor himself and it's still working going into its second winter after a summer's rest. Absolutely silent.
its a basic fish tank pump with custom guts and a PLC. Diaphragm pumps are lift only thats why in the us we call them lift pumps the one thing over looked by most is the electronic pulse pump is a fuel injector and a fuel pump all rolled into one thats why it so loud if you could replace it with just a injector or a high frequency pintle valve and a normal vane pump it would be allot quieter but improper installation would pose a fire risk im running an 8kw in a 26' class a my tank is 2' above my heater pump is on center with burn chamber with a 30* pitch hard line go's from tank to pump then from pump 6" sag under heater at night outside -25f. running on high 5mhz with a shell temp of 350f on low 1.5mhz with a shell temp of 170f roughly 1 gal. a night give or take
Great video and smart built. Did you test it with the afterburner as well? And if yes, does it keep full functionality (like measuring the amount of fuel used)?
What is that sensor type thing fitted to the front of your heater? (Drilled and presumably tapped into the main heat exchanger casting? Is that your burn temperature sensor?
@@DavidMcLuckie fit aswitch to the pump, start on diesel with the pump, then open veg oil line, turn off pump. Restart diesel pump and turn off veg dripper line for shutting down cycle, ready for reignition. My next theory is turning down the glow plug voltage to see how low it can go before failing. Same with fuel feed.
Absolutely - it's the vibe of the thing for sure. I used to supervise welders wearing similar garb and used to stir them up and say they looked like convicts all workin down there while I paced back and forth above on a catwalk above hehe. "Water here boss" they would call... the good ol days.
I wrapped mine in external pipe lagging and suspended with cable ties and I can't hear anything. But if it burns my camper down, this will be the 2nd thing I buy after a new camper. Lol
Nice review of a nice pump. Does it make a different with the silent pump what fuel you use? I’ve been using main,y kero and an odd bit of diesel here and there..
With the pump being so quiet it didn't occur to me that anyone would still want to mount it outside. I'm not sure of the IP rating of the enclosure, that would be one for James.
I know you've been asked a thousand times but is there a "better" Chinese diesel heater to buy. I've just seen they are £71.99 now on fleabay. Love the vids and as a long term boiling bag wearer I understand why you've ditched the Orange apparel. Summer mode
The Lavaner heater seems to be a better made unit. Better quality of parts and plastics. But it is more expensive, but still not Webasto or Eberspacher prices though.
I just had a brain wave. Would this deliever enough fuel for the 16kw hydronic heater ? That way I could buy one as a back up that would fit both my 16kw heater and the 5kw air heater.
Speaking of pumps... anyone know if the chinese heater pumps are less effecient/less percise compared to an actual OEM webasto/eberspacher pump(?) Reason I ask, I'm curious to know if a chinese heater would benefit (a/k/a see increased btu and/or fuel efficiency) if an OEM pump were swapped into a chinese heater(?)
Well I guess since it syphons I wouldn’t be able to use this particular pump. My tank is on the roof of my vehicle, heater is inside and current pumps inline with the heater…
Only if there's a vacuum breaker on top of the loop. Have you never siphoned petrol from somebody else's car? But you'd have to close the vacuum breaker for the pump to operate
