Customer Reviews for 12V 8KW Diesel Air Heater for RV Motorhome Trailer Trucks Boats 8kW + LCD Switch

It’s a cheap heater and easy to set up for the price, however, when the temperature drops below 20°F, this thing really really really struggles to start and instead leaks because the fuel pump delivers too much diesel when the unit is trying to heat up.

Can't review a product never got took over 3 weeks n 50 plus emails to get a refund just a heads up dont buy from Vevor cust serv is shit

Ordered another one. Hope it shows. Be nice to have before this huge snowstorm coming in.

I bought it because it was advertised as 8 kW, but in reality it delivers only about 3.5 kW. This was confirmed by Vevor themselves, who admitted the 8 kW claim is mainly a marketing label. Unfortunately, 3.5 kW is not sufficient to heat the space I intended. Here is their response Dear customer, Thank you for being so patient. Kindly note at 0.36 L/h fuel consumption and ~9.8 kWh/L, the heater can only receive about 3.5 kW of chemical energy. With realistic efficiency (80–90%), the actual heat output is ~2.8–3.2 kW, not 8 kW. The advertised “8 kW” for this type of diesel air heater is not a measured thermal output. It is a nominal/marketing rating or size class, often referring to a theoretical maximum or product category rather than real delivered heat. In practice, many low-cost “8 kW” diesel heaters deliver around 3–4 kW of usable heat, which aligns with your energy-balance calculation. Detailed efficiency or standardized test documentation explaining the 8 kW claim is typically not provided for these products. If you have any more questions, please don't hesitate to contact us.

I bought five of these same heaters they are all malfunctioning with the same part vevor has lowered their price I'm pretty sure they know what's going on they're making it almost impossible for me to contact them they haven't contact me back yet I think it's a scam shame on you vivor

Do not buy these heaters I bought five of them they're all doing the same exact thing it's the control board it throws off three or four different codes after running it for a few days they have lowered the price on this I'm sure they know it's going on and I have tried to get into their returns and they will not contact me or let me contact them this is a scam I'm pretty sure shame on you vevor.

Nu sunt mulțumit de căldură pe care o face Sufla un aer călduț care nu va încălzi niciodată

SAV totalement inexistant qui vous fait tourner en rond pour ne pas avoir a gérer la situation

Being a fool I bought this and didn’t test it right away and waited till camping trip. the fuel tank inside was cracked and began leaking directly into the heating unit. The fuel saturated into the heating unit and the fan pushed it through the tube suffocated us mid sleep and I kept thinking it must be gassing off as a new product. Missed the return window and had to throw away. It looks so nice but I wouldn’t buy again.
