Thanks for watching guys! Don’t forget to subscribe! All parts are linked in the description!
The flex pipe you have listed as a stainless steel rigid is there any other exhaust that is more workable ? Thanks for your time
Followed your video step by step and built mine identically. Thanks for all the details, it worked out great! Kept me warm in the snow when the rest of my buddies were cold
From UK, NICE JOB! Great detail and almost a tutorial for those new to CDH set up. I also admire your honesty at the end, informing ppl of existing similar devices such as the Hcalory. They are currently £140 ish in UK. But due to season they will reduce in time. Good project and irrespective of the Existence of already built systems you've given alternative kit to improve on them for owners. Well done in my view.
Well, I looked at the hcallory and it did not appear weatherproof to me so, I emailed and asked them and they said no, they are not. I have a vevor all in one i set outside my van and i have to cover it in case it rains. I want to transfer the heater to a case like in the video, then mount on the side of my van so i do not have to store it inside, and it will be fine in the rain. That will be a project for warmer weather.
Thanks for detailing your build. I went with a German Eberspacher heater sniped off ebay because I wanted a quality furnace unit. Now I am gathering info on how I will put the components together to complete the build.
Very nice build and love the time you spend explaining what your doing. I'm building a heater for my cargo trailer and placing the heater in a 20 gallon craftsman storage tub. The tub will sit on the trailer tongue and I'll port the outlet tube through a marine deck port I'll mount on the front of the trailer. I'm also using a 3 gallon marine (boat) fuel cell as my fuel tank. I chose to use the hard nylon fuel line because it will not collapse like the green line will over time. Only suggestion I would make for your build is if your fuel supply barb starts to leak use a siphon tube (straw) on the top of your new tank. Very easy to install and no leaks. I'll be interested to see how the unit fresh air inlet works being inside of the box. in theory it should work no outside contamination but heat generated inside the box could pose an issue.I also love the quick connects your using for the outlet air duct very slick, wished I would have known about them before my build. Keep us posted how everything works out and again really nice build!!
Thank you sir! Your build sounds like it will be awesome!
@@Adv4x4 Take the advice Alan offers on the hard nylon fuel tubing. Kits with a new fuel filter and a long length of hard white nylon fuel tube are available on ebay and probably Amazon too. The nylon tube is far more robust than that green PVC stuff you have and will not kink under any circumstances.
As always, very clean and professional project execution. Not a device that I am needing, but interesting none the less. Thanks John.
Thank you as always Mike!
You cannot enclose any exhaust pipe inside a container. You absolutely require vent holes in the case to vent heat from the exhaust. The wrap does NOT prevent heat buildup. It only helps prevent excessive temps that may melt plastic.
There are plenty of horror stories online of people failing to do this properly and burning down their rigs.
One way to guarantee it won't overheat is to eliminate the blower intake hose that isolates the heater to take air from outside only. Just cut the intake case hole and ditch the connector hose and the unit will pull any warm air out of the interior of the case and actually help with efficiency. If you are worried about bugs or critters getting inside just use a piece of stainless window screen in place of the dryer vent hose.
I'd like to understand better what you're talking about here. Can you explain more? I'm building on these now. Thanks
@@backwatersandbackroads There is no benefit to a sealed case. The case must have venting toward the top to allow heat to escape. There is no benefit to keeping heat inside the case. That exhaust pipe inside the case will build up heat inside and if you don't have vent holes in the case you risk fires like others have experienced. The case interior requires air flow. Diesel heaters are not designed to be enclosed inside a case. But it's ok as long as the heat can escape that the exhaust pipe produces.
@@jaysunkreuze1466 I've wondered this same thing, why is a hot exhaust pipe in the case? I've seen another video where the heater is isntalled right against the case. A cut out in the case is made to vent the exhaust right away, without pipes in the plastic case. I'd assume that be a better design?
Here is the design: czcams.com/video/JGvNHUNkhtk/video.html
This is a great video I'm using a old Makita drill box roughly the same ... Hoping will use the same idea in the workshop and simply have it so it can be then adapted to the camper if required
I bought a pre-built one two years ago for $200 and it has worked well but the case and fuel tank and such are starting to break and there’s some design flaws in it that I don’t like so I’m hoping to pull it apart and build it into a better case like this. Really appreciate the video.
At least you already have some parts to build with! Goodluck!
FYI you can prime the pump on this by holding the up and down arrows at the same time. Better than turning it on and off a bunch to start. I guess there’s different button combinations depending on the style of screen you have but I have this exact screen and it was up and down to prime.
I've seen a lot of these types of videos and this is easily the best. Thanks!
Allowing it to auto shut down allows the fan to keep spinning Ning so it pushes cooler air through system and let the ceramics cool better. Just cutting power leaves in burnt diesel in the system and can cause damage to the internals with heat not being able to escape.
This video is identical to hundreds of others. Exact copy of others.
Nobody has done the way I put one together.
I used the exact same Harbor Freight 4800 case. Mine is fully waterproof with no hose and wires tethered outside the box.
Inside the box has the heater, 20ah battery, voltage monitor, cooling fan, AC to DC charger.
I had to move the fuel pump and the filter in its own small case outside the 4800 case to make room for the battery.
It actually keeps the fuel away from the heater. The inside stays very clean without the worries of fuel spill.
5 liter tank is mounted next to the 4800 case with quick disconnect.
The case can be removed quickly for travel. No worries of spilling diesel.
Ok... Show us then. And btw, plenty of other people have put a battery inside the case though often criticized for it.
@@th33ph
I have not seen one single video showing someone putting the battery into the case with the heater. As far as I know, I'm the only person who placed a battery into the case. It's very convenient. 😉
You show us.😂😂 post a video for everyone to watch. 😉
Wow man. Awesome job with this. Im a DIYer so I’m going to build mine. I think yours will be much more reliable bc of the attention to detail of each component. Subbed 👍
Thanks man! It’s worked great so far as some people have mentioned I’d consider adding another vent to the box which I plan to do before I put it back in service this winter
FYI the silicone coupler you linked leads to a 2.5-2” coupler
Best video on diesel heaters! I'll be copying this design this summer in prep for next winter! Let us know if that fuel outlet in the tank starts leaking at all.
Appreciate you watching man! Will do! So far so good. I think it may be one of those things where the oring lasts a year or 2 then gets dry rotted but we will see 👌🏼
Great Video EXCEPT, the supplied smaller clear tube that comes with most 2kw diesel heaters is known to perform better than these kits that ship with the larger diameter tube. Word to the wise :)
Consider a vent in the box for the air intake. The box is waterproof, so if the heater is stalling out, think about where the air intake is getting fresh air.
Note: there's a way to prime it without turning it on. It depends on the remote but holding the two buttons together starts the process
Check your link for the quick disconnect coupler.
Thanks for the video! Great work as usual!
Thanks for the heads up!!
Great vid! Going to do this myself but realized after receiving that your link for 3" silicone coupler goes to an undersized 2.5/2 adapter
I have an All-In-One unit that I use in my canopy but I might gut it to make something like this. Thanks for the detailed video!
No problem dude!!
Don’t know if somebody mentioned it already, but you can vacuum prime the fuel up to the pump if you wanted to with a little hand vacuum pump.
I am building mine almost exactly as you have, except i ordered a silent diaphragm pump from Olde England
Awesome!
With the way you mounted the fuel tank nipple you could have put it on the side of the tank that is toward the lid of your box and drilled a hole in the lid making a cleaner exterior install.
Fyi, if you're using the 2kw kit, the heaters outlet and fresh air inlet is 2.5" not 3"
Love the vid and the channel! Couple quick questions I had:
- Are you concerned with the combustion intake creating negative pressure inside of the box? I’d imagine over time it would draw in a bunch of dust into the box, and put a lot of strain on the unit to overcome the pressure difference.
- Is there any good reason not to run the large intake from a duct that you’d also run to a tent/camper? It seems like it would be a lot more efficient to recycle the partially heated air as opposed to heating cold air from outside.
Thanks man! It very well could draw in dust but I can’t say I’m overly concerned as it isn’t going to be in a dusty environment while when in operation!
Also after seeing the performance of it without intaking the pre heated air from the tent/camper I truly don’t feel the need to ad an extra hose to pull in air from the sleeping quarters.
In short, it puts out some great heat! It’s sufficiently heating my single car garage so a tent/camper should be no issues even on a very low setting 👌🏼
@@Adv4x4 very slick. When you talk about heating your garage are you worried about the exhaust byproducts and CO buildup? or do you keep the garage door open? Also with the air intake inside the box is there a vent in the sidewall to allow for air movement? Not sure if I missed that part.. I think I'd want my air intake as far away as possible from the the exhaust that is reliant on sealing compound that might fail and cause cross contamination. CO is odorless and can be deadly.
@metamorph20 yeah I'm gonna have a battery powered carbon monoxide detector when I finish mine
your fuel filter is on back-to-front your filter will get clogged-up the fuel should flow around the outside of the mesh, not up through the center of the mesh,
your welcome 👍
Exactly
I'd contact Vevor to see if this heater is design specifically for diesel or if it was designed for Kerosene. The Espar heaters used in semi truck sleepers is actually designed towards the use of Kerosene. It's really odd but modern diesel blends just mess up the heaters. So in the future if your heater ever has issues staying lit I'd run some Kerosene thru it to get it cleaned out.
Thanks for the info! I’ll have to look into it
The air inlet for combustion should be outside your case. Poor combustion especially with those plastic air inlet ones supplied that it comes with. I am using a plastic and wire tea strainer as a combustion inlet cover it was a similar size so I half-inched it from the wife's kitchen cupboard. It is enough to stop bugs of dirt going in but increases the air going into the burn chamber. The heater burns far better. Noticed that there is now something similar sold on eBay. The next heater I buy will have the same put on it.
Excellent build. I'm sure you've learned this by now, but that is combustion intake and is not connected in any way to your hot air out.
The link for the exhaust pipe is the stock pipe… I bought one similar to yours but it was a 22mm… the only other option is 24mm… is that the size you bought?
Filter is wrong side should be opposite. This green soft hose isnt the best. Consider switching to hard line.
Run a flexible tube from the camper to the heater inlet. A lot quicker to heat up camper because you're not heating outside freezing temps. Just like the recycle air option on your cars AC/heat.
Could definitely improve efficiency! If I’m being honest though the air it already outputs is pretty incredibly hot as is!
doing this would make the inside of the tent very humid. Thats why when you turn on the heat in cars, it turns off recirculation so it heats up the cold dry air and sends it into the car/tent.
@@chuproductions1290 it will also reduce oxygen in the air since no fresh air is coming in
You’ve got the fuel filter the wrong way. The narrow end is the collector and then fuel should then be drawn through the thicker collar to the pump. It’ll work but its sub-optimal.
Wow, great design and build. Thanks for sharing the process.
Glad it could be helpful Brett! Thanks!
Great video
Clean work and very descriptive instructions
isn't your fuel filter on backwards? Great video
Yep
Yes
Nice job, John! Always love watching someone who's really good at their craft. Keep it up!
Appreciate you man!! Thanks for checking it out!
As far as fuel line goes, most upgrade to good quality fuel hose because the cheap Chinese fuel line works at first, but being Chinese they use cheap materials to make it. What happens is as the fuel line ages, it becomes brittle and will eventually fail. If you have trouble getting the clear line over the fuel nipple, just warm it up slightly and it'll slip on easy. Overall a good build and well thought out. One thing, I would change is running the air intake to the combustion chamber to the outside, combustion likes cold dense air to efficiently burn. One tip I would use when shutting the unit down, it is recommended to turn it up to high mode for 10 minutes after running on the lower mode to raise the heat up in the combustion chamber to burn off any soot etc. Then put it in the shut down mode. Just my opinion.
Thanks for the tips! There has been a lot of good input in the comments. I read them all 👌🏼
2023 diy means I opened a case myself and put things into it all by myself
I wonder what would work better for your set up, a diesel heater or a mattress sized heating pad. Having the flexibility to be all electric maybe attractive but also having an alternative fuel source if the weather is shit is nice too. I doubt an electric heating pad would warm up your camper as fast or as hot but who knows.
Great video, I didn't know people were diying these.
I saw an opportunity to use it to help heat my garage as well which is why I went this route! But I agree a heated blanket would probably do exceptionally well itself in the camper 👌🏼
This video is great and I had an easy time following the process except for one thing that i cant figure out. Connecting The exhaust hose to the exhaust outlet. I ordered the parts from the list and had to cut the exhaust hose to fit. Once I do that, since they're both 1" I can't fit the wavey part of the hose over the outlet. I even got a 22mm outlet (vs. The 1") and can't do it. What am I doing wrong?
If you use an outboard motor primer bulb to draw the fuel though the pump it will speed up the process 😉👍
Great idea! Thanks
A pleasure mate
All the best from scotland 😉👍
How are the quick couplings working after repeated use?
Great video! I think you mentioned storing the the 3" flexible hose inside the box. It looks pretty full so I'm curious if the hose does fit.
Thanks! Yes it fits!
Fantastic video. Appreciate all the work and enhancements you put into it. We just bought a Lavaner 2kw Pro heater and will install it in a case for our Hiker Trailer.
Thank you.
This is cool video of DIY. I am motivated to build one, I may bother you with some questions 😂
Goodluck with your build man!
Hello! I am following this build with a 2kw instead. I am at the cutting the exhaust pipe part, mine does not fit like a glove when cutting it afterwards and even cutting a slit just to get it on. No success after this, I can still use the pipe for the exterior. I found another video mentioning using the brand pipe because when you cut it and inner diameter is still the same.
This is the best instructional video I've seen on all of CZcams for this DIY build. Thank you for the video and the links.
I am attempting a version of this next week (still waiting on a few parts to arrive) and plan to use some of your ideas.
Did you ever post a follow-up on if the intake needed to be moved outside the box? Did you notice any fume or heat smells leaving it inside?
Thanks man! I ran it a bunch with the lid open after assembly to burn off any smells and haven’t noticed any since then. Honestly anytime I can have the lid open while it runs I go that route just to dissipate heat better.
A small computer fan as some have mentioned would go a long way in mitigating heat.
@Adv4x4 that's solid feedback. Thank you, Sir!
Absolutely! Thanks for watching!
I just finished my build tonight and tested it. Ran fine until I closed it up then it started smoking like crazy and fogging the neighborhood out. Punched a 1” hole in the side grabbed what was left of the intake pipe and routed it to outside of the case and it runs fine now. Definitely needed more fresh air in my case.
STEP BY STEP.........exhaust melted my apache box!
I just finished my build out and love it. But I can’t get the thing to run off my ecoflow battery like yours. Have you ever heard of anyone having issues with this?? It will run off the jump-start battery I have with no problem.
There's a prime mode
So how to you run it into the vehicle
Do you know what cables you would need to extend the remote wiring?
I had issue with the DC output required at startup, my portable power station, same as what you have eco flow river 2, keeps tripping at the start up, did you figure out a solution around that? I tried running it from my car first to get it to warm up and then switch over to the power station which works but it's a hassle.
Nice job...thank you.
Appreciate it!
I mounted a computer fan inside the force clean air into the filter
My buddy did that to his build as well!
You out the wrong exhaust hose on there amigo. Bad links make for bad experiences.
Yep it’s wrong! Once you cut it you can’t attach it to the diesel heater. 😪
I was just wondering if you still had your micro trailer? If you do are you happy with the overall material design and how is it holding up?
Why didn't you just wad all the wires and hoses into the case like everyone else??? LOLOL Great job, very neat and tidy!!!
Hahah thanks Charlie!!
I'm following along with a build of my own and after cutting the exhaust tube (for the combustion exhaust, not the hot air), it won't fit over either fitting (the pass-thru or the heater). I ordered the same exhaust pipe you have listed and it didn't work! Anyone run into something similar?
Same problems he linked the wrong exhaust tubing.
great design, especially the air outlet.
to bad I can't find a simular pipe plug. if I order the same plug in the Dutch Amazon it will cost me 40 Dollar :S
Thank you! That’s unfortunate about the plug!
Any advice please??? Following your set up - love it - but having difficulty attaching dryer hose to the aluminum connector. Can’t get the hose on - seems too small.
Thank you.
Kate
The pump is installed in the horizontal plane. But is the pump not suppose to be installed in the vertical plane?
I installed it as suggested!
Good video ,but i cant find the link for the 3d printed parts ? I hope they can be purchased from someone . Thanks
That hose is smelling real strong while running the heater. Idk why people can't smell it🙄
Which hose? The one which provides the hot air into the vehicle? What hose are you using?
I'll be surprised if it doesn't flame out due to the combustion intake being inside an unvented box.
There is gap for it to vent around the outlet flange. More wouldn’t hurt though.
Thinking about going this route vs a tent stove. Which would you recommend? If I don’t have a battery bank can I use a deep cell battery? I’ll need it for 3 nights
Can you mount and run the heater on it's side with the glow plug up? I.e. exhause would be ejected on side of case instead of the bottom?
Good video, what is the size of the fuel hose? and where can I get it?
awesome
Does the heater in the box need to breath? Or are vent holes required? Is it for the potential conndensation to escape?
Is the whole point of building this unit to prevent the need to drill holes for inlet/exhaust? I'm putting one of these in my van build and dreading the drilling of those 2 holes in the van floor. If the purpose of building this is to prevent that, this is exactly what I'm gonna do!
Yes I think people like the portability! Plus it’s easy to service if need be. Or can be used in a garage or even a house if the power is out
What gauge wire does the chinese heater controller require? Like to run it about 10-15 feet.
Did you get 2 pin for the power supply & 3 pin for controller?
Diesel filter is the wrong way around
Can you update the link for heater?
Great video. Will definitely do the same for my self built teardrop camper. I just have a question. How about the vent on the fuel tank? Did you need one? Or do you just loosen the cap a bit?
The cap has one built in!
Good job documenting build. I went with 9 liter tank. I don't like refilling often.
Did you get any fumes using inside-case intake? I expect this would be noticed when you're heading the tent.
None that I can smell! I made sure my exhaust was sealed up tight in the box with some puddy. Some people say the gasket behind the bracket melts some and creates a smell too. I ran it for probably 6 hours at home with the lid open let the heat wrap fumes burn off etc.
Hi I have also built one of these but I’m having trouble with pipes and fittings on the hot side producing smelly fumes and we actually get headaches, I have tested for any gases like carbon monoxide etc but it’s actually a plastic smell so my question is how is yours - die the silicone and or pipe produce and smell
I let mine run for quite some time with the lid open to burn off any initial fumes! I’ve also heard that the gasket that comes with the heater may produce a smell
Champion vid! Quite nice tips! Liked and subscribed-
Questions: Is the large air intake for the engine (2-3") simply to cool the combustion chamber? (I'm not referring to the small air intake for combustion air). In 'normal' interior setups the large air intake would be getting air from inside, however 'if' the sole purpose is to keep the combustion chamber cool I see an advantage with 'outside' cold air. I was wondering if you were getting enough 'combustion air' from inside the case without routing to outside air? Ta, mate- all the best to ya, Jack
Hey man! Thanks for watching! It seems to be doing well it draws in are from around that silicone coupler sticking thru the Side of the box. So issues as of yet! If so I’ll add more vents 👍🏼
Just curious there a reason so have part of the exhaust (1 foot or so) on the case before exhausting it out? Would it be better to mount the heaters exhaust right against the case, and have it leave right away?
You could absolutely do that!
Does box have good fresh air vent for heater inlet?
If you leave inlet pipe inside box, you need remember good airflow for the heater or it might interfere combustion.
There is airflow around the heat outlet hole that seems to be plenty so far! If not I will add another vent.
No one ever talks about how much power they need to operate.
How much battery for a days ice fishing at -40?!
If I remember correctly I cover power consumption at the end of this video! Also battery life is subjective ambient temperature as well.
For a honda civic would you recommnd the 2KW or 5KW heater? Or they basically the same? Perhaps more fuel usage on a 5KW? I'm in canada, so it gets cold, -15 celcius, want to do some winter camping.
I have no experience with them besides this one unit but the larger one will have to work less to keep you warm!
Quick question. Looking at heating a 16' diameter canvas bell tent in Northern NM elk hunting. Is the 5k going to be enough or should I spend $10 more on the 8k? Future use might be a roof top tent and then 8 is overkill. Thanks Awesome build!
Thanks man! I’ve used it to help break the chill in my garage so I think it will sufficiently help keep a canvas tent nice! But I also don’t think the bigger one will hurt either
Do you have a link for that 3 inch aluminum coupler set with that silicone tube?
I’ve been looking for that as well
I’m really thinking of building one like yours, but I’d love to know how it has been operating? Have you done anything else to it? Any thoughts of what you could have done better or different?
If you are into building stuff it’s a fun project! Truthfully I know a lot of people who have great luck with the premade ones on Amazon. So if you are into saving time & money that’s a solid route as well.
@Adv4x4 Yes I do like building stuff. I agree it would be cheaper buying one, but I know myself I will not be happy without spending more money modifying it. Thanks for replying.
Man soldering those quick connects sucks.And I was a jeweler years ago! Nice concept though.Needs a 90 pin.
d you have a link for the collarred bolts you used?
I do not I got them at the hardware store!
Is this build waterproof?
I wouldn’t consider it totally water proof
Can it be ran without attaching the exhaust hose to the exhaust pipe socket? Or does that exhaust hose need to be hooked up? Also, mine came with an actual muffler, did you use that down the road at all?
Yes it can be ran without the pipe! It did come with the muffler. Admittedly I haven’t tried it yet. Isn’t very loud without it!
isn't the case airtight? what about the air intake?
There is a gap around the outlet pipe that lets in air! Been running fine like that so far
Update, any melting issues? looks like you are using better fittings but I had an issue w/ it being super HOT in the case after hours and days of use
How did you resolve that? Im about to build one. Exhaust fan?
@@RT-qz5ci Sorry so late... So i did not with the case. Since I have a truck, I opted to weld a steel cage vs a boxed method.
My fittings had melted (maybe cheap amazon fittings) I would do more research on that. I dont the fan would assist the heat output fitting.
I really think you just need a better fitting. The heater blows VERY VERY hot air.
The Amazon link for you 3” silicone coupler is actually for a 2.5”-2” reducing coupler….
Do you have the link for the 3” one?
Did you ever find that link it to a 3in coupler? If you did please pass it on to me. Thank you!
I need 3.5 inch
diy diesel heater? " diy diesel heater case" "diy diesel heater enclosure"...... next time i expect pc fans baked bean tins and a glow plug from a landrover !!!
Hahaha I like your style!
By all accounts, that green hose isn’t great.
Apparently it’s prone to splitting from various posts I’ve read, so something to keep an eye on
Thanks for the heads up man! I’ll keep an eye on it and replace as needed.
Are you having any condisation issues with the heater being on it's side. Also, how many hours of run time can you get on one tank of fuel, Thanks
disregard the condensation, question, I seen it being built on it's side, thought it was the way you was installing it.
Not sure on hours run time but I’m willing to bet that tank will do 2 8 hour nights depending on how high you have it on 👍🏼
Another question I would like to ask, is the diesel heater unit capable of maintaining one temperature inside, can the unit turn off and on by itself to maintain the set room. If so please let me know how. Does the unit continuously run and you have to physically turn it off in order to not get the room overheated. Do you have any suggestions, thanks again in advance
The little monitor sees what the ambient temp is and runs unit accordingly 👍🏼
Why buy it if nothing it came withfits
