My only complaint is the exhaust tube is not long enough so would be nice if they offered more options.
Burns diesel
Burns oil/diesel
Burns used oil/diesel mix
Now this is a must have if you have a diesel vehicle.
I installed it into the cab of my Volvo truck.
Fitts right under the passenger seat.
Blows the hot air right where its needed.
I have the bump installed outside, so there is no noise.
Installation may need a little cutting and drilling.....
Very happy with it.
I own 5 Vevor diesel heaters, 2 in use, 3 for back up. They ALL work great, and the prices can't be beat. Heat my Garage and Basement easily, and cheaply. I haven't had a problem yet.
Initial I had trouble keeping it running. I found it needs a dedicated 12 (battery) source
Run great. It's in my shop now but, my pan is to heat my covered van.
It works great. It won't heat up a big room but it will take the chill out the air. If you were to let it run constantly it probably would keep it warm once the concrete floor warmed up. Keep it in a smaller room it works great.
