Customer Reviews for VEVOR 5KW Diesel Air Heater Muffler 12V 5000W Diesel Parking Heater 2 Duct Diesel Heater Double Vent with Knob Switch for RV Car Bus Motorhome Boats

This has been one of the worst purchasing experiences I’ve ever had. I ordered a unit (Order #241122009778025172XX) that arrived late and didn’t work at all. The product was defective out of the box, and despite spending an entire day troubleshooting, it would not turn on. When I reached out to customer support, they kept going back and forth with unnecessary instructions, refusing to process a simple return or refund. Frustrated, I placed a new order (Order #241129009778180835XX) on Friday, expecting it to arrive on Sunday as promised. It’s now four days later, and the order hasn’t even been shipped! What’s the point of paying more for expedited service if the seller can’t deliver on their promises? This whole ordeal has been a massive inconvenience, delaying my plans and leaving me without the product I needed. The lack of accountability, delayed shipping, and refusal to address the issue properly is completely unacceptable. If you’re considering buying from this seller, save yourself the headache and go elsewhere. They clearly don’t care about their customers or fulfilling their obligations. I won’t be buying from them again Unless this situation is fully resolved—including processing a refund for the faulty unit, expediting my new order, and providing proper compensation for this mess—I will not change this review. This seller has completely failed to deliver on both their products and customer service. Save yourself the headache and shop elsewhere.

This company is almost impossible to deal with. They sent the first heater, and it stopped working and wouldn’t turn on after only 3 weeks use. There is no phone number to talk to anyone, and the chat service is horrible. It must be AI chat because it kept asking the same questions. So now I have a heater I paid almost $200 that stopped working after only 3 weeks. The 2nd heater failed to get sent to the correct address twice!! And again nobody to talk to . I cannot recommend this company to anybody, and I will never do business with vevor again.

Need better user manual. Set up no problem but how to use the display to set the clock and other settings are not clear

I had Great hopes for this unit. For the first 6 hours they were met. No unusual or unexpected troubles. However, after turning it off and leaving it for 20 hours, the unit would not restart. The LCD screen would not power on and the unit was dead. Vevor did not have a exact replacement in stock to exchange. Had to downgrade to a model without Bluetooth. Still awaiting arrival. What I can say about the Bluetooth is it's rather poor designed app. It doesn't have many features in the ones it does takes up more than a full screen so you're constantly scrolling.

Works great , heats up fast , controls could be a little easier . Have to really figure out how to set temp so it comes on and off on its own

Easy as could be. Pour in the fuel and press the on button. Would have liked a longer exhaust system, but most people aren't running it across a shop floor. Overall, great product and good price.

Heater arrived dead on arrival - will not power on regardless of power supply or battery (all 12v and 15-20amps). Support won't process a return without proof, but all I can show is that it doesn't power on.

Bought the diesel heater filled it up hooked it up to a 12volt battery turned it on and heard a poof and that’s it it won’t do anything? What can I check ?

Great heater. I've installed it in my van. It's performed well from 150 ft. to 7,659 ft. The altitude indicator is fairly accurate, with in 100ft.

Won't start on a 10amp outlet needs 15amp so a120ac adapter to 12 v dc does the trick works fine straight off a12v auto battery so if you want to run it on house current get the adapter
