Testing a $140 Chinese 8KW Diesel Heater #vevor

I have seen these Vevor diesel heaters all over the internet so I just had to get one and test it out. It works much better than I expected and I am dreaming up a few ideas to put it into action on the homestead. What do you think?

We have a few of these, use them for preheating aircraft engines, just stick the hose end into the cowl and let it run.
They slso work great for preheating tractor engines as well in unheated sheds.

I have one in my garage- 20x24 garage and living up here in northern Canada where it gets to -40 it's handy. I can keep the garage above freezing with one. I ended up building an exhaust out of 1" copper that goes up and over the wall and out the eaves. I ended up putting a T right at the end of the flex exhaust hose and short piece of pipe to capture any condensation that may happen. I'm pretty happy with my setup for it. Don't have your exhaust running uphill or it will fill with condensation as I found out and then the thing will smoke out your building really bad.

I bought one 3 years ago and it has been great.

These heaters are awesome! Heated a 35ft 5th wheel trailer all last winter. It ran 24/7 from october 17th until April 25th this year and i used 122 gallons of Red diesel. On the lowest setting on Alpine mode it would use 1qt for 8 hrs brilliant heaters, would highly recommend them. The Vevor unit is the best make that i have found👍

The lock code is for advanced settings it doesn't lock anything else. You can adjust the fuel to air ratio the hertz of the fuel pump. The code is 1688 if you want to see the settings.

It is intended for the air intake to take in outside air. That way you prevent having to draw cold outside air into your heated room. So both the black intake hose and the exhaust go outside so the burning of the diesel and the exhaust it entails basically is in its own outside loop. The internal heat exchanger takes the produced heat and circulates it inside your heated area.
What I have seen some people do to increase the efficiency even further is route the exhaust through an old central heat radiator and then to the outside. That way a lot of the heat of the exhaust is also used.
In all these are primarily used in campers, rv's, boats. But I have also seen them used in houses as an alternative or even main heating source. Your battery setup would work for shorter periods. But I would combine one with a small/medium solar generator, combined with some solar panels. That way it would work even during an extended power outage. Lots of videos on the diesel use and energy use for the pump/display (battery capacity) on youtube to help calculate your needed storage of diesel for the max periods you expect to use one.

I bought one a few years back for my 8x10 greenhouse and it works well during the early spring / late fall nights. I also purchased a length of fuel line and it draws directly from a 5 gallon can. The display brain box isn't the best so keep a spare.

The unit is designed to draw in outside air and heat it to prevent negative pressure that would draw in cold air into your shop from outside.

I ordered one to put in my van so I can sleep in the van when I'm on the road doing gigs. I will likely replace the propane furnace in my 1970s slide in. Furnace still works but draws too much power. I will use that on multi day gigs so I have plumbing, fridge and stove. The production trailer will get one to keep equipment warm on below zero days. And I will likely buy my dad a few for his trucks and his "house" .

Thanks. Lots of uses. You mentioned a sap shak. I did about 900 taps a long time ago but I made about 130 gallons of syrup and a bunch of candy. Hope you do too.

[danrascal]

Thank you for the great video! I was contemplating buying one for emergency use . Looks like not a bad idea to have one.

You can hook it up to the 12v output from a power supply out of an old desktop pc

Nice! This would be just the ticket to heat my goat barn. I will build an outside enclosure for it and duct the heat into the barn. The "barn" is a 12x16 wooden shed with OSB steel covered roof. Should keep the little girls ( dwarf Nigerian) toasty warm! Beats trying to use electric heaters! (Yes, my babies are spoiled 🤣)

[theresad]

Perfect timing on this video! I've been hearing a lot about these heaters and I've been considering one for my camper. Thanks for the up close view of the set up and for testing it for us.

How long does the battery power last before you have to shut the heater off and recharge the battery

[ChristopherSeaDawg]

I bought one and put it on my covered back deck. I ran the hose through a 3” hole I cut in the back door. Works great on heating the entire downstairs. Curious to see how much I save on my gas bill.

[karlmcnamee]

they have been using these in simi trucks for many years as bunk heaters a lot of co. still use these now

[syrgeo]

I have a plan for a large SUV where I want to take the front passenger seat out and cut a hole for the exhaust where the seat sat and route the exhaust out the hole. Obviously sealing up the hole after routing. It would be a nice camper suv.

I’m going to be very curious about the longevity of this type of unit. We truckers have similar units underneath our sleepers, drawing diesel directly from our main fuel tanks.
The units in our trucks cost thousands of dollars, and the only thing reliable about them is that they’re totally unreliable. I’m not sure what the problems with them are, but I’ve always suspected it was an issue with the digital thermostats.
Please keep us updated on yours, Todd. If it holds up, it would be something I’d consider getting for my truck.

wonder how much battery power is used...a fully charged battery..how long would this heater last...?
