Custom Garage Mini Furnace Using a Vevor Diesel Heater 

Check out my follow-up video linked in the description above.

Fuel line should have been far from the exhaust as possible. The exhaust is set up like p-trap and will tend to hold condensate. (Raise your unit and have all the exhaust going down hill), I would also recommend running off a battery with a trickle charger. So in a power outage you can still have the proper cool down. You can put solf foam around the pump to dull the pump sound. The pump should be mounted at the recommended angle. The (opitional) power switch should be located where you don't have to reach over the unit in an emergency if you decide to keep the 110v. I would have mounted the fuel filter vertically under the tank and double check the flow direction. I would have mounted a fuel shutoff valve immediately below the tank. I would have mounted the fuel outlet in a straighter path of the fill lid and avoiding the mounting screw pockets. I would have mounted the fuel tank at the same height +/- but off to the air intake side and not above the heater. I would have drawn combustion air from outside rather the consuming heated air. P.S. the colder air also expands the air volume of the flame making it way more efficient and have cleaner exhaust. Other then that the file cabinet was a good idea.

Innovative and clever👍 I’ve bought 2 of them and I’m using them to heat my small home. Saves me a ton of money not using electric heat

Ingenius!!! Nice video sir!!

I concur with all the construction points raised below. Drill another hole in the siding and take your combustion air from outside. If the thing is not set-up properly, it may soot-up, causing incomplete combustion products to reverse flow out of the inlet. Purchase a Carbon monoxide detector for improved safety, run the pump vertical. Kerosene burns cleaner. Stay safe!

I like the idea of putting it in an enclosure for safety. I think i'll do the same thing when I install one in my garage.

Awesome idea. Thank you for sharing. Some great suggestions. Everyone stay safe, warm, happy and healthy. From Henrico County Virginia 😊

Thank you for the video! I have a differing opinion - put the fuel tank below. If the pump fails open, if you have the fuel above, gravity will dump the fuel into the heater. The pumps are designed to last for quite some time and mitigating a fire hazard is always a good thing. Also note - you should consider adding a battery backup if some sorts so if it stops, it'll at least fail over to safely do cooling during shutdown

I installed similar recently. I extended the exhaust inside running it through some box section filled with sand. The idea was to capture some of the heat from the pipe. Exhaust of course then gets vented outside. Most of these kits seem to come with inferior clips and green pipe which people tend to replace before install. The fuel tank I had is same as yours. If I was doing it again I would have a pick up pipe installed at the top of the tank, less likely to be a leak problem and you could have the intake picking up just above the bottom so that you weren't picking up rubbish that accumulates there. Good tip to use exhaust paste to make a seal. As someone else said, you have your fuel line with hot pipe either side of it. Thanks for the video, instructions are not great with these things so it's good to see other installs.

neat stuff... looking forward to updates and what you have learned. we're all learning!

Thanks your set up is nice great job

I like the J Mount Grinder set up!! Nice work scotty

What i have learned so far on these and some suggestions. Tank does not matter above or below pump. The pump should be mounted on vertical surface at a approx. 45 degree angle to one side or other in proper direction. Recommend upgrading fuel line to nylon fuel line, green fails. That power supply your using is a converter/charger, so you can run the unit off a 12v battery and charge at same time in the event of a power outage. If you shut these down before cool down is complete you can destroy your heater, really must have battery backup or a automatic whole house generator for quick power recovery say in like two minutes. The heater goes into cool down as power is restored. As others have noted exhaust is a trap, must all flow down, exhaust installed like this lead to sooted heat exchanger over time and a real mess. These are simple but they do have some must does when installing.

Nice work

I have two heating my off grid cabin. They don’t put out much heat, so don’t be misled thinking you can heat your house with one (unless its extremely well insulated)

Nicely done.

I DIY installed a mini split heat pump in my shop. More expensive than your setup but no worries about fuel, and provides AC and dehumidification in the summer.

Nice install but for the space and money spent, you could get a good mobile home oil furnace and still run it off diesel and a simple 110v install. I installed one in my 20x40 garage and it heats great. Exhausted straight through the wall, no chimney. My FIL has one of these 12v diesel heaters in his garage and works well but takes some time to warm it up.

This is one of the cleanest installations I've seen. The only things I would change is a battery with a trickle charger instead of an inverter in the event of a power outage and lowering your exhaust to eliminate the loop. The condensation will accumulate in there and you've created sort of a p trap. Realize your concern regarding snow accumulation, but with the heat coming out of the exhaust it shouldn't be a problem. Not trying to be nit picky. You did an amazing install that will probably be just fine.

Happy New Year Scotty & your family, I hope you can keep it on a proper temp in your work spot. Greetings.Hubertus

Very interesting setup, creative use of an old file cabinet. There are some issues that you will likely need to address in the near future however. These fuel pumps need to be installed more vertically, 30 to 90 degrees upright, because they create cavitation bubbles. the bubbles will collect in the horizontally mounted pump, since all the lubrication for the piston is provided by the diesel, the upper half of the piston will wear out quickly. Looks like the fuel filter is mounted backwards? the combustion exhaust should have a continually descending path, because water is a byproduct of combustion and the water from diesel combustion is acidic, so it will corrode through that low point, allowing exhaust gases to escape into your home. You can also realize an efficiency gain by routing the combustion intake outdoors, so you're not consuming the heated air from indoors to support combustion. The green PVC/ vinyl tubing is not well suited for this application, it will become brittle, crack and start leaking fuel. upgrading the fuel line to a 2 mm ID rigid nylon is probably the most common upgrade folks do to to these heaters from China. I would also suggest you take the switch out of the supply circuit to prevent an accidental shutdown. If you have any risk of a power outage, I would replace the power supply with a 12V battery on a trickle charger. Any loss of power to the unit will prevent the required cooling cycle from running, which will typically result in an overheated/melted ECU. Take a look at John McK 47 video library here on RU-vid, he has a great reference library of diesel heater information ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-TGFDFZ6r1dI.html . Best of luck with your unique installation!

Nice setup. It would be best to have a continuous downward slop the entire length of the exhaust, with no U shape in it. That is what I did with my CDH setup. This will prevent any condensation from ever collecting inside the exhaust. If the CDH ever starts to operate funny and might even seem like it is backfiring, remove the exhaust and see if there is any water in the bottom U shape section of your exhaust. (It so happens the other day I watched a video of another youtuber that had this happen with his setup.) All the best, Tony

The biggest mistake I noticed is the loop from the exhaust which will favor the collection of water from the condensate in the exhaust - this means it will malfunction over time

Take a look how built my enclosure but your set is kool

I have w vevor 8kw in my workshop size slightly bigger than a double garage. 2 heaters transform my garage from 3+ to 18+ clcius within 40 minutes

The odds of the fuel pump failing aren't worth having to fill the tank at shoulder height. They typically don't fail if they're burning clean diesel.

Exhaust pipe already has a burnt spot under the bottom of the box. Raise the box up higher.

Great vidro Scotty and a very nice set up. Do you think this would be suitable for the bay windown bus. ???

Nice build! Do you have any issues with the fuel pump not being on the recommended angle?

I like the use of a 2 drawer filing cabinet, I might copy that. Combustion air intake should be mounted externally. I don't see any backup system to run the shutdown sequence should the ac\dc power supply fail or malfunction.

I bought one. I think I’m just gonna drill a hole in the cap and push the fuel line down in the tank.

Also not cutting down your job it’s a cool idea but the exhaust being with the loop on the bottom will hold water ( condensation)

I saw a guy talking about the exhaust and it stuck in my mind. He said a byproduct of that combustion is moisture or water that might collect in the flex pipe and restrict the airflow, causing soot in the heater I haven’t used a diesel heater and maybe I’m wrong but I think I’ll try to make the point where my exhaust vents out a little lower than the connection on the bottom so it can go downhill the whole route.

I installed a Chinese Diesel heater in my 6x12 cargo trailer conversion... I spent all my effort making sure I properly exhausted the unit through my 1 inch insulated wall using a thru-hull stainless outlet as well as using high-temp RTV around my exhaust hose with high quality hose clamps, and thought everything was great.. I now know that I need to also properly setup a thru-hull port for the combustion intake (away from the exhaust). These devices are primitive.. don't trust that the exhaust flow will happen in one direction with 100% certainty... and don't expect your Home Depot CO detector to save you either.. I've smelled the funky smell, and let it go... and it made me pretty sick.. Don't ignore it... do it right. ...also, if you drop the diesel pump frequency, the exhaust-to-intake leak is even worse... Treat the combustion intake just as important as the exhaust itself.

I noticed you have your fuel pump horizontal. The manual shows it is supposed to be mounted 35-45 degrees from vertical.

you don't need a fuel pump if fuel tank is above the heater.

Can anyone say how much it burns in a day? say it's heating a shop 900 sq ft, insulation is pretty.

Question for everyone. Can the control panel be changed to fahrenheit ?????

The pump is suppose to be at an angle. Something like 35% Happy Newyears

YOUR FUEL ILNE IS TOO CLOSE TO THE EXHAUST PIPE THIS GETS REALLY HOT (FIRE HAZARD) !!!!!!

"CRAPPELY"

Car charger? Say no more. I see the problem.

How can you be so smart with everything else, but then totally F up the exhaust? It needs to be either always downwards or even and downwards. You went down, up and then back down... totally negating the entire point.
