'Chinese' Diesel Heater

[StreetSleeper]

Cards on the table: really happy with the heater and the LED display I find very helpful. Coupling it into the original heating ducting was amazing, the difference is literally night and day. Down side: outside you can hear the exhaust, couldn't tell you how far away as the van is parked between two houses and now to the pump: as we turned the heating down the noise of the pump became more noticeable. At the temperature that we found most comfortable at you could definitely hear the sound of the pump, I can only describe it as the sound of a dripping tap......not loud and wouldn't affect conversation or listening to the television but it is there. I tried cutting three of the tie wraps off and though it made some difference the tapping was still there so I replaced one of the tie wraps and the pump is hanging at the right angle but a lot looser this time. I cannot see me eliminating this problem other than insulating the pump. If it was resonating through the body it would be more of a thump than a click but that can wait. My next job will be to tidy up the van and get it ready for when we can go away.

Sorry I was teasing about the cable ties. But seriously the fuel pipe can carry a lot of noise. I wonder if using longer lengths of soft rubber fuel pipe would help? The pump itself would be better held in something soft.

Did you try putting the fuel pump lines in and out with a 90 degree bend? That is meant to make a difference (I have done that from the start, but still hear it. maybe it would be louder on mine if I hadn't done that?)

I hate ticking clocks and the pump is like a ticking clock. But .... I've got used to it I have the same ticking with the tacho and that has become white noise in my head now.
So guess what I am saying is just live with it for a while and see if it "mentally" if not physically disappears?

Mine is like a ticking clock but it doesn’t bother me.

Rae it works fine connected to the original bigger hot air ducting then? If so I will definitely look at changing mine to the bigger ducting.

I would like to take this opportunity to thank everyone for their feedback; good, bad or indifferent it has all been vital to the completion of my Chinese diesel heater installation.

Yes I had a feeling you were taking the p155 but I wasn't biting
I have already tried insulating the pipe where the P clips hold it to the body, perhaps I should have used more but the pipe between the two chassis rails is not touching the body.

Hello David,
No I didn't, I felt sure suspending the pump would cure all these problems; unfortunately, I was wrong (nothing new there then). I have just gone on to eBay and bought an insulation pump cover so this will be my next course of action.

Hello Nabs,
Well actually I cheated a little bit. If you have a look at the pictures you will see what I did.

I cut the original tee piece and slotted it inside the Chinese tee piece, held it in place with some mastic and connected it up to my original pipe work: it seems to work fine.

Never used Kerosene and not sure where I could get it, maybe a place near to me in Mytholmroyd, but would need to check.
Seems to be only 28p per litre !!

All filling stations have it on pump here or in 20ltr drums called 28 sec heating oil.

Where ? Scotland ?
And interesting, will have to do a bit of research

Ah, I see
Thanks @Edina

28p a litre would be an amazing price. I paid around 50-60p/litre when I filled my tank in March (decided as a precaution in case deliveries became a problem as didn't know how the Coronavirus effects would go), which was of course before oil prices plummeted.

This has been an absolutely brilliant thread, which I should find helpful when I get to the point of firing my heater for the first time. Can't see it happening till at least August as my build continues at pace.....snails pace!

Be interested in how this pans out as I would also like to reduce the clicking noise if I could

 

[Nabsim]

This just shows how noise affects people differently. I think my compressor frudge is quiet but some post they are too noisy, my DT4 did sound like a jet engine close up before I fitted I take and exhaust silencers but it didn’t bother me and anyone close never complained so I don’t know. I say my genny is quiet But someone else may disagree. I am deaf on certain frequencies (too much loud music an head banging and noise at work) and so is Caz so it probably helps

When I fitted my pump I cable tied it to the plastic diesel tank and I thought I had done a great job eliminating the ticking sound , but as the tank got emptier the ticking got louder until it was thuding , so that idea soon got binned and now it is fixed onto a piece of solid rubber but if you listen hard enough you can still hear it , I cured that by turning the radio up

Just had another read through this topic and I have decided to un-install my heater and order a turret. It just looks so right, that the expense of a turret and hole saw has to be worth it, so many thanks to Rae for his fine article with photo's.

On further investigation my Eberspacher is using the original heat ducting just not all of it. The reason I thought it wasn’t (apart from not all vents active) is because I have some much larger pipe under the bed and second set of larger outlets. Turns out these were from the heat exchanger on calorifier feed lines and not diesel heater.

I'm sure I've got a hole saw and arbour you can borrow if you like... (ill check later)
It's in Manchester but happy to send it via Hermes if it helps.
