Customer Reviews for VEVOR 3KW Diesel Air Heater 12V Diesel Parking Heater Muffler Diesel Heater with Knob Switch for RV Bus Car Motorhome Boats

I found this very easy to install. I am an aircraft electrician by trade. If you are not handy, then you might have a tough time on install. I put this heater in my 18 ft cargo trailer and powered it with the \"Ecoflow River 2\". Pretty sure any 12v deep cycle battery would power it no problem for days. Once it's started, it uses very very little 12v DC. It puts out a lot of heat. We camped 2.5 days. High of 40°f low 28°f used 2 gallons of diesel on lowest setting. Kept wife and 1 year old baby warm the whole time. The hardware is very cheap but for the price of this thing, I was very happy with it. Tip: never remove 12v power while it's running. When you press the power button, there is a shutdown cycle that must happen. When your battery dies or you disconnect the heater without proper shutdown cycle, it will flood/ foul and won't work the next time without needing disassemble.

Very happy with it no issues at this time. It gets hot.

Works great for keeping a garage warmer in Michigan Winters. I'm not saying it's hitting my garage to 70-80 but it definitely keeps it not freezing in there even on the lowest setting. The garage is 2 and 1/2 car non-insulated a very efficient heater

Perfect for a garage heater. Easy to install. We were able to combed or to a plug-in instead of battery power.

This is a great little unit. I bought it to use in my home shop small square footage and also I could put it into my sprinter van or small Schooley bus. This thing was priced very well and operates magnificently, and does exactly what it is stated in the description when you buy this Look forward to using this in the future. On my road trips across the country and I plan to buy a couple more.

Works perfect

Wow these work really great. Plumbed this into a winter cabin duct work. Figured be good addon heat, but it works so well I use it for the main heat. Got another one just for the garage. Shipping was fast and this product as most I have got from Vevor pretty well packaged.

2 of the 4 were damaged. But that isn't their fault. Good little heater. Produces alot of hot hot heat. Wish it was in Fahrenheit but it's what ever.

heating un-insulated 2 car garage/@500 sq ft,/46 sq m. . first use over night, 37 F/ 2.75C outside , chest height 64 F/17.6 C inside, appears to consuming 5/8's of inch of fuel per hour / 10 l tank. noise level acceptable in a garage, though i would not want to be standing near it all day. i am planning on creating a sound barrier for the fuel pump. assembly was pretty straight forward, the most difficult was the slipping the fuel line over the nipples, until the final connection of the device slipped on very easy and the supplied clamp was way to loose/had to use a different clamp. no instructions on how to to assembly the fuel tank nipple into the tank.

I just hooked mine up today so far I have no problems and for a diesel heater it is quiet
