Heating systems are the gypsy's biggest challenge. If not warm, it's not home. If old, it's going to be a lot of peeing at night and that makes bundling up in a bag a bit of a pain. Loved your movie "Overland." I do recall your plastic one and I am in awe of you expedition life style.
Use insulated flexible ducting to retain the heat inside the ducting from your design to your tent . You will use far less oil to last days .

What a great idea to have the second duct for a second tent. I'm stealing this build
I think your idea is going to help a lot of people to extend their camping season.... good on you.
I hope so. It's definitely made my wife more willing to winter camp!
Good info! thanks for the vid. Couple ideas, some mentioned below but Ill repeat:
> combustion air intake, dont take this from outside. Pull it from in the box and remove 2 of your aluminum vents. this will improve combustion efficiency and burn off/vent any fumes accumulating in the box from spilled diesel. Combustion air doesnt mix with the heated air so no worry about fumes entering tent.
>for extra fuel capacity you could get outboard boat motor fuel connectors they make some nice spill proof connectors that you could bulkhead mount to the box then use an outboard fuel tank and hose.
>Combustion efficiency is way better with hot air and warmer fuel, a couple turns of copper line around the cooler part of the exhaust and running the fuel through it first will help in really cold weather. also pickup the combustion air from around the exhaust pipe. this helps reduce soot and carbon buildup from incomplete combustion.
I feel like an idiot. I thought everyone was telling me to pull the fan cold air from inside the box, not the combustion air. Pulling combustion air from inside the box makes SO much sense - no chance of snow or rain getting in, more efficient burn, cold air pulled into the box to cool, and less stress on any filter. Thanks for explaining that to me - I’ll do that!
@@RevereOverland what does it look like inside the box then? I'm building this now per the video but it seems youy may have changed it. Thanks!
'
Awesome idea! It looks like you have enough room for a small 12v battery and charge controller. You could mount a 10 watt solar panel on top and be entirely self contained. Just a thought.
Yes, I think it would be pretty easy to make everything 100% self contained!
It’s important to use the hard plastic fuel line. The fuel pump works on a pulse principle to meter the amount of fuel flow. Any flex in the fuel line will affect the amount, so if a soft fuel line flexes the pulse energy is waisted in expanding the soft line instead of moving the fuel through the line. When using the soft black rubber connector host, the hard plastic fuel line MUST be inserted all the way so the end is touching the adjoining element, such as the fuel filter, fuel tank, heater inlet. The black rubber is only used as a cheep simple method to connect the hard plastic line.
Here in Canada it is called dyed diesel. Farmers and commercial fishermen use it as well as companies that use off-road equipment.
Very informative and complete video. Thank you for taking the time. For the inside of my Excursion where I sleep, I'm currently using a Portable Buddy Heater with an extended hose a large propane tank. Yes! A LOT of condensation and then it freezes on the inside of the windows when the heater automatically shuts off. I'll be doing some sort of mounted Diesel heater solution on the inside and running off the Excursions diesel tank.
Very good set up. Just remember you want the glow plug up. It can be on its side as long as the glow plug is up. Very good video. Also on ebay look up diesel air heater all in one. This is what I use in my enclosed trailer and out in my hobby shop. Have fun, be safe.
My buddy is getting one of the prebuilt setups, so I'll probably do a review on it for next winter!
@@RevereOverland I have 3 of the All In One heaters. 2 are were the fuel tank is above the heater unit and 1 that has the fuel tank to the side of the heater unit. Please check out John McK 47 youtube channel. He's a wealth of knowledge on these diesel air heaters..
He's a great resource, which is why I recommended people go check him out at the end of the video.
Hands down the best video I've seen on building your own self contained diesel heater. Your demonstration was easy to follow. Plus you gave other options. Honestly you should give yourself a well deserved pat on the back. I subscribed because I learned a lot from your video. Well done. Thank you.
I had a 5 and used it for my travel trailer it was 27 foot long. I used it threw the winter. i loved it never had to turn my furnace on and it was about 2.50 a day in desial
Having been a trucker for thirty years, i have been told many times by fuel companies that diesel fuel and furnace fuel are practically identical. The only difference being the addition of a dye to the furnace fuel to indicate that road tax has not been paid on the fuel. Contact local fuel companies and see if you can purchase small quantities of furnace fuel to run your heater. The furnace fuel is much cheaper.
Someone said that some gas stations sell gas free diesel too, but I've not asked for just filling a gallon at a time!
Be careful with heavy heating oil. It may burn dirtier and coke the heater up.
@@RevereOverland I wonder if these heaters would burn Kerosene? Just a thought..
@@wesleymcgonagle3394 I heard of other folks burning cooking oil and waste oil so I would imagine so.
@@wesleymcgonagle3394 th-cam.com/video/qpLhwuy9M9E/w-d-xo.html
Looks good. Great starting point for people to further customize it for themselves.
Thanks. It's definitely easy to customize to your own needs!
Great job on the upgrades.. thank you for listening on the return. It'll dry his tent faster with the return... think of it like your house.. it circulates your air inside. Not from outside.
Actually a return will increase humidity because you're cycling back the air you're humidifying. Bringing in fresh air constantly will help keep it lower. Either way, it's not a problem, because the heat lowers relative humidity enough for it to not be a problem at all!
Another tip for you, seal around the holes that were drilled in the bottom with some rubber washers then if any fuel is spilled it won't leak out the bottom of the box. It really looks much better in the metal box. Good job. Maybe put a small fire extinguisher on the side of the box.
There is one being produced in China that has a casing and built in tank ,also a didital control system .Ive not fired mine up yet but will let you know when I do ,just added extra hosing to get the hot exhaust out my bell tent and air intake outside ,almost finished the shower in a box very happy with the results so far thanks man another good video .
Great upgrade over the prototype. Well done! One suggestion for when you want to split your output duct to heat 2 tents, put an adjustable louver or gate on the end of the shorter hose so that less hot air enters that tent & diverts more heated air through the longer hose. This way you can balance the heat distribution between the 2 tents a bit better. If it's really really cold outside, try wrapping the duct hoses with a wool blanket or some other material that will insulate the hose & have you lose less heat going thru it. But overall, Version 2.0 turned out great. Very impressive!
Yeah the ducts definitely need insulation for use like that - I lost a TON of heat through them. It's not something I planned on doing though. Andres found out I was bringing the heater the night before and insisted I share the warmth!
Thank you for all the info. I like the idea of putting this heater in the boxes, and that box on the top rack. For me I gonna probably do this, but for the box, I m gonna use Milwaukee packout toolbox , I m not sur what model I m gonna use, but all my set up in my double cab and my truck bed I have Milwaukee packout system.
Ya John Probably Knows More About Them Than The Germans ,Chinese or Russians & Ya Watch ALL Of His Videos He is A Expert on Them , Great Video
Such an awesome job!! I'm building one of these and your advice is invaluable. Thank you!!
Thanks for the info. I need the heater to do the same thing for my wife. Great video.
Good work. This series has been quite a labor of love.
Use a remote fuel tank for an outboard engine. You can get them in a variety of volumes. There are many different styles of fuel quick connectors with check balls so they will seal the minute you disconnect the line and only leak about a drop if that. The mercury and OMC are the most common.
I really thought about getting an outboard motor fuel tank. It would be a good alternative, and have plenty of capacity.
Revere Overland it would also make your set up more modular.
Great build! If you didn't want the screws to stick out where the gated vents are on the front, you could turn the screws around with the head on the outside and use a nut on the inside of the box to secure.
loved the build. The only thing that I wouldn't do is connecting the combustion air intake to the outside of the box... I would have only 1 vent (instead of 4) and let combustion air inlet suck the air out of the box. This way when this is mounted on the roof rack less element can interfere with the heater.... Especially when there's rain and snow blowing everywhere.
Good project, if you use it regularly on camping trips with a tent, shelter, or van. I would customize it to be fixed on the back of the car (outside) somehow like some big fifth wheel does. You then add the duct and start up the heater. Fuel could be inside the car or somewhere near it. Hook it all up to your 12v car lead-acid battery (with a 16A fuse) and add a second one in parallel if you actually gonna need it. It uses only a total of 1Ah capacity on startup (with a 6-minute peak of 7-10A) in the first 30 minutes, after that, it uses only 7.5 Watts to maintain the 20 degrees. A standalone 1KWh 12.8v battery unit will get you more than 120 hours of heating with 10 startups-stops. It will need 30 liters of Diesel. You could actually heat your home (or parts of it) for far less than your heating bill is worth.
Could you tell me please how much Ah should have a battery to power it in low to moderate mode for 2 nights? Im too stupid to understand it.
If you find it a bit noisy you could also run a sound deadener inside that metal toolbox then install everything. You won’t hear the fuel pump at all and will really quiet down the fan noise. And also for your fuel tank, talk to a metal worker and get a stainless steel fuel tank made that will utilise your space to maximise how much fuel you can carry.
I believe the intake muffler you eliminated was in fact a water trap like a scupper cover on a boat it is a baffle so the water drains and just air enters. Nice video
Based on the design, it doesn’t appear to have any use other than sound! It’s definitely not a filter.
I really liked the follow up from your previous video, and the revised setup looks great. For the ends of the screws sticking out, you can see if acorn nuts will fit to clean up the look. Another suggestion is foam weather stripping that have an adhesive side. They’re not too expensive, can easily be cut down to size, and are compressible for the lid.
I believe you covered all the safety points but just to make sure have someone in the HVAC building trade go over your build and see if they have any recommendations.
Missing one small thing could lead to problems. You will sleep better knowing that you have done it right!
You can use Red dye diesel for this heater. Additionally you could look into building your own lithium battery with a set of super capacitors for powering your heater.
The vent louvers you used have little screens in them. The box itself is your burner intake filter, and it will also burn off those diesel spillage fumes, and lower the heat build-up in there.
I would consider using your Heater BUddy for about 5-10 mins and then you should be good to go to run it on Low rather than high. Once you heat up the space briefly it should be easy to maintain it
_Nicely, done! Just get the 5Kw that so-called 8Kw are the exact same as the 5Kw. They were just rebranded. Don't spend the extra money on the 8Kw._
Nice build, if you plan to build another insulate your box , it will keep it even quieter and have less rattling , an aluminum box will essentially turn into a speaker especially late at night when you can hear a mouse fart at 50 paces.
I could also put the muffler on, but so far it hasn’t been annoying since the white noise from the fan drowns it out!
As a retired Navy mechanic for submarines, you missed so many opportunities to make that efficient as possible but you are still young and learning. Excellent video though.
"Opportunities" such as...?
lets hear the improvements for v3
Dude that is really cool. You did a great job on improving the first one. It makes me wanna build this. Thank you for sharing.
Thanks! It's an easy build. The only recommendation I would make is make sure it fits on the roof rack in case some diesel leaks - it stinks!
Fantastic build and detailed video. Well done. Like some I nearly died when you did the first build but loved the update. Well done. Make sure to doe a follow up.
The 3kw heater is the 2kw heater with rich fuel pump settings.
For the shorter pipe, could be used a butterfly valve in it
Thanks very much for the discussion of fuel use on these. I think the 3k has the more efficient low setting.
Beautiful build, I just noticed on mine that the rubber chinese fuel hose is cracking and generally falling apart. after two years the plastic fuel line is good but I'll have to replace the rubber stuff. These kits are really cheap now My first one was $400 and my new one was $150cad!
Yeah they’re a great price. I used rubber fuel hose that I had left over from Autozone, so hopefully it’s a little better quality!
If you change fuel tanks you might want to consider using a draw straw instead of pulling fuel from the bottom of the fuel tank. Eliminates chance of leaking and picking up dirt from bottom of the tank.
Try a Motorcycle or lawnmower muffler. Lawnmower mufflers would probably be much cheaper. Personally, I might try 2 mufflers in series to quiet the monster down even more.
On the power-thru wiring, folks might like powercon connectors (used in professional audio systems-made by Neutric).
Instead or mini tiedowns, use footman loops. Cut off the hooks on the straps and fed the sewn loops thru the footman's loop.
You need to build another one for your buddy's tent. That will make your tent and his much warmer.
He needs to build his own! Lol.
here's an idea , get a toggle latch it will also keep the lid from rattling
Well done. Love your work. Though I'm glad these are now available in an All-In-One version. But I don't think they will work for you as they are not designed to be mounted permanently on the roof rack. As far as fuel is concern, why not just get a 5L or 10L jerry can to hold your spare diesel? Rather than re-desining your heater box again to fit a larger fuel tank.
Great video! Thanks for telling both Fahrenheit and Celsius for us using Celsius :) keep up the good work. Much love from Sweden! :)
Only the US uses such a weird measurement for temperature, so I had to!
@@RevereOverland In Europe, it is Celsius, smiles
Thank you so much.
I will be watching you more.
Thanks!
Nicely done! Some good ideas. Thanks for the aluminum translation, I was lost for a moment. lol If you're going to have the air return in Andres' tent you might watch what he eats for dinner that night 😂
Yeah I was pretty concerned about taking air from his tent. On the bright side, whatever goes down the return air will be heated, and sent right back to him!
Like a scene from rocket man lol
all I had that day was taco bell and monster drinks lol
andres vivanco The choices we regret... and Rob’s were the biggest regret. 😂
Very nice build.. but I have to admit I like the original tool box one better.. not as polished. .but so simple.. I have one of these heaters on order and will be building something similar to make a portable heater.
To cut down on heat loss through the hot air delivery tubes perhaps consider using insulated versions or insulate your current one's.
Great show! for a lid gasket, try smearing Vasoline on lip and a nice bead of silicone on lid. then close lid for a few hrs. Cheers.
Silicone would do the job nicely. I was thinking self adhesive weather strip.
Great concept I would only change to a remote fuel tank just to avoid the hassle of it being on the roof. Plus bigger volume to suit the needs of a longer trip.
If you have a rear bumper it might work well for remote fuel. My previous design had it separate, but I prefer it self contained personally. If you do have it separate, make sure you have valves... diesel leaks are nasty!
@@RevereOverland if I go that route itll probably be overly complicated knowing myself. Great video though.
Nice Land Cruiser in that group. 👍
It definitely is! It’ll be in my next video.
Good job. V2.0 turned out great. 👍
I think you would be better of with Dynamat on the inside to dampen the sound.
I would not worry about the heat inside the box when it is ventilated. And Diesel is also more efficient when preheated.
Thanks. The sound from inside the box really isn’t noticeable over the fan white noise, so I’m pretty happy with it. I like the diesel being the box too, since it helps keep it a little warmer!
I have been looking at these heaters for a long time and am trying to come up with something that we can swap between our camper trailer and Coaster, I'm still not sure I am all the way there yet but this has some interesting ideas.
I bet in a years time there will be a bunch more videos and builds with interesting ideas to work from!
Very nice build. I watched the prior versions first and although it was quite fine....this one takes it to a whole new level. The foam strip around the top will not only help quite it ....it will also help keep it dry. Was wondering if you provided any type of drainage in the bottom....just in case. A small 30ah no maintenance battery would be a wise addition as well. It should fit nicely in the box toward the output port....if only for backup purposes. BTW...I subbed.
Excellent video man... thank you for the effort. I am in the middle of my build and am running into fuel issues. I am struggling to find that nylon fuel line which I suspect will cure my issue
Lowe’s sells it!
Revere Overland thanks man.. will look for it
In thinking doing a diesel bunk heater not sure on box I use , I bought a 6 gallon scepter boat gas tank with a quick connect I plan on mounting on rear hitch inside awning that attach to rooftop tent heat rises diesel fuel will burn much cheaper vs propane in planning to sell Mr buddy heater only use bunk heater as far as price Chinese brand much cheaper vs espar brand, I like winter camping vs summer anyway nice set up in still working on the design but check out scepter fuel tank and maybe quick connect on the fuel line that way you can carry bigger fuel tank
I would have farted in the intake tube to the other tent! *carbon monoxide scare!!* lol
Прикольно придумал👍 ёмкость под топливо маловато наверное будет,нужно будет доливать постоянно🤔а так идея зачетная
The design is really great actually for the air in being an unshielded/uninsulated portion. However in the heating duct if you use a rigid line and insulate and shield it you should see better heat output from the device. This would conserve as much of the heat being created to the outlet. Any heat produced from the device is already heating the air entering which is nice as this would reduce consumption of fuel and operate more efficiently. Overall this is a far superior setup to the previous. The most concerning portion however is the loss of heat in between the box and the tent. I'm not sure how you would solve that unless you built a rigid duct and insulated that as well. Would be one more thing to lug around though. I'm rambling.... Its a brilliant idea! Cheers!
Yeah I struggled with the balance between efficiency and portability! Straight, smooth, insulated ducting would be best.
It's better than nothing! It gives you far more opportunity than not going at all because of temperature. All in all great idea and will likely use once I obtain my GFC Camper. Refreshing to get a comment back from a TH-camr. Cheers again!
This is a beautiful build you have done ✅ 👍
I was thinking of making one just for outside my tent when I go tent camping. I did just order a mr heater big buddy on Friday so I’m going to test it out and see how well it works and how safe or unsafe it makes me feel. The thing about those buddy type heaters is they can shut off if you’re in high elevations. I had a dyna glo one do that to me while camping in South Lake Tahoe.
Plenty of people use the Buddy heaters with no issues, but I still had a CO detector and metal baking to sit it in! I'm not sure how the diesel heaters do at high elevations - it's something I'm unlikely to ever test out.
Use a carabiner to hold the latch shut, rad build brotha
Thanks for the video, I'm wanting to put my heater in a box on the tongue of my travel trailer.
That would be a great use!
Excellent video! Been waiting for this one to come out. Excellent presentation! Definitely going to build this come fall for my RTT setup. Thanks for providing the material list it really helps. Take care
Thanks! It's easy to do, and helps keep the whole family comfortable.
You could probly look into the water prof gates like on gray/black water tanks.
There were clues that you have watched John's videos, but you must have missed his explanation of why there can be no 8Kw model. They all use the same .02 pump with max pulse of 5.5, which gives a theoretical 4.4KW. I would consider a shorter taller box, something a 10l tank would fit in. I would draw the inlet air over the hot end of the heater to both cool it and also preheat a little.
Yeah I missed that one! Thanks for the correction.
Hopefully your going to change to a different power plug. 12v socket can become unplugged causing unfortunate problems with the heater not having a proper cool down period.
I would recommend having a designated onboard battery such as a simple 12v9ah AGM in your battery box and then if your going to have the 12v plug into your solar generator, install a blocking diode.
That way, if you accidentally get unplugged from your solar generator, you have a backup battery in the box to keep the heater running (until the voltage drops and the heater does a low voltage shutdown safely).
Additionally, the fuel tank on the hot end side of the heater, not an issue, I linked my heater video in your first one where a thermal monocular was used to show what was getting hot and what was not.
My heater case uses an onboard battery 18ah AGM with 5.5a smart charger than I can plug in my solar generator to charge up the battery (yes I know energy loss from DC to AC back to DC) but I can change out solar generators without ever shutting down my heater.
Additionally. I have done power draw testing. I've had at max wattage for startup, 130w and max at shutdown 100w where the max overall power draw on both a startup and shutdown sequence was only about 18w of power consumed from the battery.
Additionally, running the heater on low after startup draws about 6w and on high upwards of 45w.
All power connections I use are XT60 connectors from the RC world where all plugs sending power are male and all recieving are female which is a common layout among the RC world.
Interesting feedback, thank you.
I was more worried about the hot exhaust than the hot end of the heater, but with the exhaust wrap, and it being secured in place, it’s not an issue. I may add a second tank at the other end, but would have to figure out fuel transfer.
With the battery I would probably do as you suggested if it was in a moving vehicle. The 12v is not a secure connection at all! With it in the tent, laying on its back, it’s unlikely to be a problem though!
@@RevereOverland the 1 time it does come unplugged, you will likely destroy your heater at the minimum.
A simple $20 battery and a couple dollars in extras, easy to wire into your setup, the simple being able to swap solar generators without shutting down would be a huge convenience alone besides the safety should it ever be unplugged accidentally (or the 12v plug blow a fuse).
It's a cheap upgrade which had peace of mind and convenience built in.
Your choice if you want to do it or not but I would not be surprised if at some point down the road, it gets accidentally unplugged and at the very least, destroys the heater or potentially catches fire destroying an expensive build and leaving you without heat.
I think you did a great job ! I have one of these in my Jeep but the tent setup is a cool concept...
Thanks!
Nice video, but if you put a rubber grommets in the hole for the mounting bolt for the fuel pump it will dampen the vibrations.
Yeah there's definitely more I could do to cut down on fuel pump noise. Thankfully you can barely hear it inside this box.
I know this is an older video, and you may already know this, but the 8kw heater is really a 5kw heater in disguise. It doesn't put out any more than 5kw of heat. Great video though ! Thumbs up!
Great video! Very informative series. I've learned a lot so far. Any way you can make a video on maintenance on the heater? Thanks and keep the videos coming.
That’s a good idea. It probably won’t happen until late next fall though - I’m trying to avoid becoming a diesel heater channel!
The build is cool but that music is awesome!
you should pull the air from the tent to the heater inlet instead of heating very cold outside air
Draw burn air in over the exhaust pipe to pre heat it and increase efficiency
You could definitely have it pull air from inside the box (which will be warmer from... everything), but I didn't want to pull from where the fuel is.
Nice job, some fine tuning as you said and you have it made.
If you mounted the fuel tank higher on the side of the box, it would be easier to fill and would allow some flow to the pump from gravity.....
I’d honestly like to put a larger fuel tank in its place instead.
Déjà vu.
Greetings from France 🇫🇷
Inspiring me to build a heater!!! Thanks for the video!!!
A diagram of the final design would be good. Much easier for people to build if they can go by your plan of fitting with measurements.
Do you have room for a second fuel tank of the same size? If so then simply add it along with either a fuel switch or some piping to create a larger fuel store? Perhaps mount the second one slightly higher and at an angle so that it'll drain into the first one?
As for the second air hose, add an insulating sleeve to it. You can buy fiberglass insulation sleeves for air conditioning units at Home Depot type places. That should gain you a few more degrees.
Yes, I believe there is space to stack them. It’s not something I wanted to deal with after I spilled diesel inside my vehicle with just the one tank!
You need 12v computer fan to force cool air in or out of the box to provide cooling.
The heater unit actually cools itself through the air it pulls through the heat exchanger, so the box temperature changes very little.
Great videos on the diesel heater. Im building a trailer for off road use and I may just use one of these instead of white gas or propane. Thanks!
I'm hoping we'll start seeing more of the gasoline and propane models. Right now they're pretty expensive still.
Very nice build. Thanks for sharing.
I bet lining that box with Dynomat would make lots quieter.
Use a agm battery it will run all night and use 20% way beter than lithium and will charge up faster
I'm having difficulty placing your accent: you sound mostly mid-west American with a taste of Ozzy. Love your projects!
Thank you for making this video, been looking for a different option for heating my tent.
Check out my latest video with the Propex
Did you get diesel fuel smell into your tent? Seems it would draw it from aluminium box through into the tent. Slick idea. I would consider a snorkel exhaust mast so you do not suck CO into air intake. Best
Great video!! Your pretty creative.....I'm over here like......I can tie my shoes!! So I got that goin for me! Lol
Lol! I can't take all the credit - a lot of this was from the comments on the last video!
Careful with the diesel heaters. If ran on low for extended periods they will clog up with carbon on the inside. This results in extremely thick half burnt diesel smoke puking out of the hoses. If this occurs in your sleep you may not know it happened....
Nice setup. You could put some acorn nuts on the screws that stick out from the outside of your blast gates to dress it up a bit.
That would look good. I'll keep that in mind for future projects!
9.25A startup/shutdown or 112W - 0.5A or 7w when in tickover
I don't understand why you drilled a hole for the combustion air intake when you invented the enclosure quite adequately. Couldn't you draw air from inside the enclosure?
Yes, and it would be more efficient too. I just didn't think about it!
Put the T closer to the box and it will more evenly distribute the heat
That’s what we did the second night. It helped cut some of the heat loss too!
What about a pelican case or roto-mold cooler. Expensive yes but water tight and probably very quite. Also, look on Amazon for a fuel pump jacket, may help with noise and only $6.
I think a Pelican case would work well too - it all depends on the space you have available! Good call on the fuel pump jacket - if you're mounting in a plastic box it could be a great way to cut the noise from it.
