I am not affiliated with Vevor. I have recently, Like most purchased their products. I consider them the manufactures, for many products, made for American companies, but overseas. Now they are getting their daily bread. And, its well deserved. This Diesel heater is great. It does what's expected. I do not like the whole "bottom" exhaust by design as I feel it makes it more of a burden to exhaust, especially when dealing with the surrounding heat. Other than that I like that it runs for a while. I probably on high heat used 1 gallons for about 6-8 hours of heat from it. It can put out heat and with good force for a low voltage fan. ( Diesel heat, but the fan runs off the 12v power supply, as does the ignition I believe).
So far the products I have from Vevor, Macerating pumps, this heater, a Refridgerant recovery machine, Refrigerant tanks etc have all been well served. I purchased this unit in November, 5 months ago and no issues.
Thanks Vevor.
