For those that know, these Chinese diesel heater pumps are noisy and there are many people that have tried to make them quieter.
If you're looking for a solution, here is the first one.
So far, so quiet.
Or is it?
You tell me.
Also did some temperature measurements to check the heater fresh air input, exhaust output and hot air output as well as the "package".
Take a look at the results in the video.
Here are the items I used:
2kW heater: amzn.to/3g0kINT
Foam: amzn.to/3AlaJvV
DEI Exhaust wrap: amzn.to/34ZuRb4
Extension pipe heat: amzn.to/3rBpmqX
90 degree: amzn.to/3KyfF4Y
Thermometer gun: amzn.to/3tIl8jS
Extension exhaust: amzn.to/3AhAv3U
Questions, let me know.
Thanks,
Keith

Thank you SO much for your videos! I just got my ambulance on new years day 2022 and am just beginning the conversions into a camper for mostly rustic campground, boondocking trips. Your sharing your experiences, ideas, solutions etc is generous and greatly appreciated by people like my me. Thanks again and have a Blessed day. :)
Hello Christine! Congrats on your new adventure ahead of you! Glad you've found them helpful and provides you with a flight path to plan your odyssey!! You're welcome~
Great stuff very quiet ,just be aware of the base of the heater usually has a seal on the base (red or black ) this was designed so it seals the base of the unit to a floor so no fumes can leak upward into heater area and then into habitation in the event of any exhaust fail or other leaks .
Thanks, dude!
its very hard to explain in words but I built a small plywood box for the pump and suspended the pump with loops of narrow gauge bungee cord so that when you shock the box the pump moves freely suspended in mid air the shock wave made by the pump as it clicks is absorbed by the bungee cord and silences the pump completely two holes drilled in the top of the box over the pump shafts and a looped bungee cord around the pump shaft four loops pulling the pump to the centre of the box so it hangs in mid air seems to work very well indeed, you can still mount the pump easily at 45 degrees. There are also some solutions where others have mounted the pump with zip ties to allow the pump to move as it clicks, the general consensus is to allow the pump to move freely as it clicks thus absorbing the shock wave it produces.
Have any photos?
I did it very simple to ours. Use a car radiator hose. I am into the automotive sector. So i could get one what perfectly fits around the pump. Only the connector part could not fit. Put at the other site whats is free another thick rubber hose into the bigger one so that a lot of the pump is covered with rubber. Big difference according old situation. You can hear it ofcourse but a huge difference than before and at a very comfy level. Think simpel…..
The fuel pump is a solenoid pump. The noise is natural.rubber hose on each end and suspend with clothe strap or rope. Even tie wraps will transfer the noise because they’re hard material.
Has to be soft or vibration will transfer.
Hi Roger. Great suggestions. Wanted to protect the pump. It is encapsulated in foam so it is sort of suspended in air.
not sure if your pump is vertical at least 30 deg but it should be to add life.
Pump may over heat. Need a heat sink. metal mass mold around pump will deaden the pulse and dissipate heat.
Wtf is metal mass mold? R u an american? Why u ppl struggle to speak English properly? Just say a metal box!!
Putting you in for the "Real men of genius" award. I thought that you would use a pool noodle. I would remove the heat guard. You may want the fuel to expand due to the heat to have a longer flow. I love the ambo. I have a type 2 and love it. Best investment I've ever made.
Thanks Scott. My sense is it still can expand and contract within the foam and will monitor it to see how it performs. Yes, these are well built machines!
Get rid of all that plastic and cheap ducting and get semi ridgid dry duct. Home depot has 3" everbuilt semi ridgid duct - it works perfect. It will make 90 degree turns etc and stay in place, wont melt/smell, and is way cheaper and easier for connectors
if that is soft, open-cell polyurethane foam, could it degrade and become sticky over time?
I’m not understanding about the noise complaints about the diesel heaters , I have two of them in my house and they sound like a really quiet dryer , Ian’s I barely hear the clicking of the fuel pump I don’t get it .ones a 8kw and ones a5 kw
The ticking is quiet inside and out. That's not a problem for me... But, I do have a problem. I just put on a muffler and it didn't do a thing. I can hear the exhaust coming out still fairly loudly, and I can hear, what seems to be a fan? It's very loud and a bit of a higher pitch... Inside the camper it's fine. But outside it's very loud and obvious.
Is it your wife?
First of all, nice looking conversion :-). I would be somewhat concerned about the fiberglass exhaust wrap breaking down and getting sucked into the cabin air of your vehicle. It’s hard to see, but the wrap material is constantly shedding fragments of glass.
sorry to say but you shouldnt have the pump horizontalit wears out quicker as its not lubricating properly and will be prone to creating air bubbles in it resulting in an inconsistent flow...look up john mack 47 on here,he is really good on them and explain better.
how long does the diesel last?
Depends upon a host of variables like the outside temp, your desired inside temp. However, there is a hand pump that you can use to pull from the main tank. But that tank will last 3+ days from my experiences.

No worse than a grandfather clock!
