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

TLDR: I’m happy with this 2KW heater, but I wish VEVOR hadn’t locked down the fuel pump and fan speed settings. I upgraded to a quieter pump. I like the Auto on/off feature that turns off the heater. Installed this 2KW heater in my small A-frame camper, and it was a much better fit than the 5KW heater I previously tried. I chose to upgrade to the “green” fuel pump which is much quieter. (The heater noise drowns out the slight tick from the green pump.) overall, I’m happy with my purchase, but there are a few issues. The altitude mode appears to work. I am typically camped at or above 9,000 ft. While the heater appears to adjust to a leaner mixture, I think the default settings are too rich. VEVOR has apparently disabled the advanced fuel and fan speed settings in the current Bluetooth controller. I like the new start/stop feature of the Smart mode that can fully cycle off the heater like a home thermostat. Using this mode appears to keep the temperature +/- 2C of the set point. (+/-3.6F) which may be two wide of a temperature range for some, but works well in my use. This mode is only available using the Bluetooth app. While the temperature mode can be set to Celcius or Fahrenheit, the controller appears to internally use Celcius.

Good product good price as described

Bluetooth holder ikke forbindelsen. Jeg skal parre den på ny vær gang.

gekauft 10/2025 Terrasse beheizt. Gute Leistung.

Looking forward to putting it together, though we are coming into warmer weather now, so it won't be used till it gets colder. Cheers.

Bought it for working in my garage in winter. Great heat production.

This is the second purchased Their purpose will be to take the chill from an outbuilding this coming winter. The first one I purchased was a Vertical, this one is a split... Reasoning for the split is that I would like a larger oil tank than the built in on in the vertical/horizontal units. With a remote mounted tank, you can add another, or larger tank much easier. Manual is printed too small, and could use some editing to north American english

Have purchased 2 of this model diesel heater. First heater lasted 2 full heating seasons without needing any servicing (1000's of hours); only replaced SS screen and glow plug once. Second heater was replacement for 1st at 4 year, died after only 100 hours of operation; Motor is seized / dead. Diesel Heater is used as backup heating approximately 6 months for Pump / Battery Shed (NE USA, when below 32 deg F). Replaced defective heater with an 'All in One' from another manufacturer.

I took a customized approach and installed this in the tongue box of my “square drop” camper. I did not use the supplied green fuel or the supplied fuel tank. I bought a stand pipe kit and a standard 1 gallon gas can instead. The heater does work well, but because I bought the Bluetooth version, the controller is locked down and I can’t get into the customizing mode. Take your time do some research and don’t be afraid of upgrading components.
