If you take the old chrome muffler and add it to the air intake, cut off a short piece of the 1 inch black tube, insert the muffler add the short piece of tube back and then put on the original black plastic filter it will decrease the combustion roar considerably. I have a heater installed in my camper. With just the chrome muffler on the exhaust, I can hear the roar from 35 feet away. When I put a muffler on both the exhaust and air input, I have to get about 15 feet away begore I hear the combustion sound!
I put a rubber molded case on the fuel pump and made sure it was not touching anything. Also the piece you added is known as a accumulator. The green soft fuel line acts as an accumulator by softening the impact of the pump. I have done this with my heaters and the click of the pump is almost inaudible. The soft rubbery case on the pump is a must. Purchased one of the quite pumps and still havent had to use it.
Watching from Australia great video it will help me with my heater, yes it’s hot here in Australia but cold in the early mornings in the bush. Thanks for taking the time to make this video to help other campers well done mate.
Thanks for trouble shooting it! That’s the exact heater I was planning on getting for my overland trailer. The upgrades are almost as much as the entire heater but silence is priceless.
I have this same unit and can say stock, its insanely loud. I would also suggest adding a fuel filter since these vevor units dont come with one installed
Hi there, I have watched a few of your videos. I was curious out of all the CDH’s you’ve tried, which one would you suggest overall. I would assume accessibility of parts to deaden noise would be a necessity.
My go to is the hCalory SS2. While I did need to do some mods on the case to make it serviceable, the form factor is the best of them all and I have had zero issues with it.
Thank you, Sir💕💕💕💕 So is normal dad bad nose of the fuel pump. maybe I change it a day, But for now is ok. I turn it off when I go to my sleeping bag♥♥ I pay that price to buy a good electric blanket.
New sub. Great video, my current interest is these new diesel heaters even though I live in Florida. I get this feeling the powers gonna go out just when when it gets cold. Thank you so much for all this information. You have saved me a load of time.
Cool 6:14 I've never actually seen one of those used. Same as you, I've never seen the one before either. Great video.... Wow. That pump is impressive. I can appreciate all the time and effort that went into making this video 👍 Haha... yes, those original cheap "mufflers" don't' do a lot. They change the pitch and lower the volume a little. I was going to suggest hanging the pump from o-rings or springs... but it seems you have completely solved it without doing that. Have found a lot of the sound is transmitted through the mount ... but again... well done ! Quieting the air / fan would be more of a challenge. Some of that deadening material on the plastic housing may help a little, but I assume most of the noise is the air flowing over the fan itself and the fins on the exchanger. You could spend a lot of time filing and sanding every edge and make a little difference, haha. That being said... That insulated hose probably makes a difference.
My biggest issue was more surprising. I was going to go cold weather camping and was running tests to see what setting I could run the heater at. At 10F, I had to run it on level 8 to get the tent to 50F and maintain it. Any less and the heat loss through the tent walls would drop the temperature almost immediately. I even ran a hose from the tent to the cold side of the heater to try to make the heater more efficient, it just couldn’t keep up with those outside temps.
@@TrailTraveler I experienced a similar thing with the silly test I did recently with my inflatable suit, only I wasn't recirculating at all and I only used a 2kw heater.... and it was -20F ... Not a good situation. At 0F it could keep up no problem, -20 it was rough. This may seem like a stupid question, but Did you have a sealed connection at the air inlet of the heater ? The heater you show is in a case so I picture perhaps a hose to the metal case instead of to the housing of the heater. I'm kinda surprised by yoru results... but with a decent size tent and no insulation I suppose there's a heck of a lot of surface area to lose heat through.
I was using the newer Hcalory heater and the stupid thing is assembled with rivets so, with the time I had, I couldn't drill out all the rivets to make a sleeve inside to get a more sealed system. I was also hoping that letting some of the recirculated air into the case would help keep the diesel from gelling up in the cold. I was thinking that I might be able to tweak some settings and maybe increase the temperature and lower the blower speed. At the end of the day, the lack of insulation in the tent is my weak spot.
@@TrailTraveler They may put something in our diesel here in Calgary, but I didn't have issues with freezing at -40F the past week, so you should be okay. If you can create direct recirculation, I would imagine this makes a huge difference. Sort of like a chain reaction. As the chill comes out of the tent, the air going into the heater will be warmer, meaning the air in the tent gets warmer, and so on. There are plenty of anti gel agents as well as "home remedies" like a few percent acetone, I believe. I want to experimenting with some tent stuff just out of curiosity, but I don't know that I will have time as I have so much on the go.
I'm going to drill out the rivets in the Hcalory case so I can get into it. Then I can seal up the air intake, and do they quieting mods to it. Then I want to figure out how to put it back together with bolts so it is serviceable in the future. Probably will have to use rivnuts.
I did all these modifications but I’m having a problem with mine…. It turns on and runs for about 2 minutes and shuts down I have it connected to a Anker 535 power station
The only power stations I have used that reliably power the diesel heaters from the DC port are Bluetties. I have to use the AC plug on all of the other ones.
I honestly believe some people are just extremely sound sensitive. I have spent several nights in the middle of no where with one below me in my RTT. I find the "sound" from diesels pretty much white noise and sleep like a baby.
Hey Kerry, I just watched your video and I must say that it was really nice and well-made. I was wondering if I could help you edit your highly engaging thumbnails which will help your video to reach to a wider audience .
My comment was deleted. As an experiment i found one inlet silencer was quite noisy so i placed the exhaust silencer on inlet and seemed quieter than the black plastic silencer. Some of them have a roar sound.
My first inlet silencer on van had foam inside, the second i bought was empty. Now third has mesh inside. Mesh one just fitted noisy so put unused exhaust silencer on it.
I saw a video where the guy showed the heater blew out considerably hotter air when the intake was taking in warm air. Why not put a stainless pipe on the intake and then place it side by side touching the exhaust pipe which would warm the intake air ??
A stainless pipe is too bulky for us to take with us everywhere. My simple solution is that I have both hoses next to each other under a moving blanket.
@@TrailTraveler Am i off with using the same flex stainless pipe for intake as used on exhaust and running them side by side touching until the end of the intake where angling it away so as not to melt it? the two pipes coukd be wrapped with aluminum foil or some other heat sinc. Any addituonal heated air going in would benefit as long as the air was clean correct?
@@FountainGuru If you are referring to the intake and exhaust of the diesel motor, this could cause overheating problems. I was referring to the fresh air hoses. I run the hot air hose up to the tent, then another one coming from the tent to the cold side of the heater. The warmer the air going into the heater, the warmer the air coming out will be.
@@TrailTraveler That's funny. Ya when you watch every one say it I guess it got you... I watched a pro golfers channel last night and I really liked his style... He said "Hey if you like what you just watched we are going to be doing a lot more of that on this channel stay tuned." not the like share and subscribe... even typing that it makes my head hurt.
@@youmebornfree For sure. I think it was some crazy hour in the middle of the night and my brain wasn't functioning fully. I may say something like you can find the GPS files on our Patreon, but usually I just say "stay safe out there, we'll see you on the trails"
The company who makes the first silent diesel heater with even more control of fan speed and temperature will take over the diesel heater market those Chinese ones are so loud !
@@TrailTraveler Heh... Yup, it's me ! I've been wondering if this hose would stand up to the temperatures. There are a few cases where it would come in handy. I saw your thumbnail pop up and thought "I should ask this guy" haha.
I don't like to be critical, but since I would like you to continue living I'll take a risk of upsetting someone. Your heater exhaust is blowing into your shop. Maybe you have plenty of air flow, but in case you don't, please be careful of carbon monoxide! The lady that bought my father's house got in her car and warmed it up. Her husband found her later, still sitting there, dead. I don't want that to happen to you!
Thank you for your concern. I did have the garage door open while filming. HOWEVER.....I actually ran the heater as a test, inside the garage (3 car garage), with all the doors shut, for 6 straight hours and monitored it with a carbon monoxide sensor and the levels never went up. Lowered Expecations did the same test in a much smaller garage.
For $90 it should be quieter! I just made sure my pump wasn't touching the sides (that's half the problem) and just wrapped it with insulation and I don't hear it at all.
90 is cheap. That's why it's simple, and a bit noisy. I don't ever remember being able to buy anything like this 20-30 years ago for this kind of money.
