Silent Pump for Diesel Heaters - test / review

[@randallleroy210]

"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

[@metricstormtrooper]

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.

[@guitstikkustoms4448]

Your video was my first intro to the silent pump, thank you.

[@carpenterfamily6198]

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!

"I saw one video" ... can you provide a link to the video(?)

[@purdypart]

​@@__WJK__ i think it's Mel's big van small world Channel

[@MHLivestreams]

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.

[@1knightinbangkok946]

Yeah. Just watched that video and not completely silent. Maybe 60% silent...

[@Riscyrich]

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.

[@Simon_Rafferty]

That's a good innovation! I find the ticking kind of reassuring, knowing the heater is still working! Then again, maybe I'll drop James a line!

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 !

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

[@Brndjsiue]

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.

[@jumanjimedia6324]

Where did you buy it

[@MIck-M]

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]

PVC vacuum tube? You have piqued my interest.

[@fionnut]

@@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.

[@MIck-M]

@@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.

[@vihreelinja4743]

@@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.

[@fionnut]

@@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.

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]

You just need to make sure there isn't enough height difference to start a siphon. Taking the fuel supply from a stand pipe into the tank also helps.

[@craster_van_kippers]

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,

[@dockerandy]

install a relay controlled tap in the fuel line.

[@1allan2]

I potted my standard pump in silicone (neutral cure, roof/gutter) within a electrical junction box and we can't hear it at night anymore !

[@jaybee258jb]

Hmmm. Now you got me thinking. That's an easy one to try. Thank you.

[@duncansampson8120]

yeah ive ordered a silent pump off James he as fitted a anti syphon so you can fit the pump higher or lower than the diesel tank

[@Islandwaterjet]

How about installing the pump inside the tank submerged ? Would this muffle the pulsing ?

[@MHLivestreams]

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.

[@brycestewart3181]

If that was a check valve it would not be siphoning ?? If it is a filter, it would be good to know in case it got plugged. Maybe it is an exspanion tank to help dampen the flow. Thx for sharing

[@ericbrockhus2518]

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.

[@banffscotland1]

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.

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.

$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

[@renstillmann]

Yeah I agree. But the time you put into it building it yourself is probably not worth it.

[@DEADB33F]

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.

[@Gary-ee3kq]

What size tubing did you buy?

Hey David, could the white filter looking component be an anti siphon valve?

[@capman911]

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.

Sad to tell you, you've probably been mis-sold a heater. There are only two heater sizes and they are physically different.

[@DavidMcLuckie]

Yes and no. It doesn't 'need' to go outside. But the reason to take outside air is so that you are not burning the air in the space you are heating. As you then are drawing in more cold air from outside to replace the air you've used to burn and re-heating it.

Are they only for 12v? Can they be used for 24v?

[@DavidMcLuckie]

It's possible James could make you a 24V version.

It's good to see something that is not made in China. Although the Chinese kids do have to work, to support there families😇
