12V 9kW Diesel Heater ，Extra Large Aluminum Body, High Power Diesel Air Heater LCD Display, Overheat Alarm, Low Noise Parking Heater for RVs,Trucks, Ships

Very stable, best quality from other 3 wich i had before, 9kw have about 20% more heat than oher 8kw . 9kw is heavy than others all

Total garbage. The control box won’t stay on. Turns off 35 seconds after turning it on. Then won’t turn back on. Have to disconnect the power source to reset for the 35 seconds to start again for it to turn right back off again Don’t buy

Had a few issues with the first unit sent. Never fired up. The unit is well built, I'm guessing something occurred in shipping. Second one came, fired right up. Exceptional quality of customer service and the unit is the best I've owned. Heats extremely well, pump is more than adequate for the power output. Fan is huge flow. I'm hearing a 1500 cubic foot space around 200 square feet. I'm sure at 10-15 degrees fahrenheit outside this is more than adequate. Thanks to the company that manufactured this and sells it, I'm a happy camper!!!

Good heat output

There is no instructions nor does it say which is intake ir exhaust without trying to fire u the unit

As a frequent traveler in my RV during colder months, I was blown away by this diesel heater – it's become my go-to for staying warm without hassle. The large aluminum casing feels super durable and handles heat like a champ, making it perfect for long hauls without overheating worries. With its 9KW powerful output, this thing cranks out serious warmth even in sub-zero conditions; I tested it on a recent camping trip in the Rockies when temps hit -30°F, and it heated my entire RV space in under 10 minutes flat. No more shivering while brewing coffee!The 9 adjustable settings are a lifesaver – I can fine-tune it from a gentle background heat during mild evenings to full blast in a blizzard, all while saving fuel. Plus, the remote control feature is genius for real-life convenience: I start it from my truck cab while parked a hundred yards away, and it syncs instantly with the display to show temps and fan speeds. That means I know exactly when it's warmed up before stepping out into the cold.In practical terms, this heater shines in everyday scenarios like overnighting in my semi-truck or weekend RV getaways. It handled high altitudes smoothly during a drive through the mountains, and the auto-cleaning mode kept maintenance easy without any messy cleanups. Highly recommend for truckers, campers, or boat owners who need dependable, no-fuss heating!

This 9000W beast is no joke! Finally found a diesel heater powerful enough to warm my entire Class A RV quickly, even on the coldest Montana mornings. Forget chilly corners – it delivers serious, consistent heat that makes the rig feel like a cozy home. The build quality feels solid, definitely a step up from others I've tried. Perfect for serious winter adventurers needing reliable warmth.

Good solid beefy heater, but you can't control this heater by temperature. It only has 9 heat/fan levels and no thermostat control. It's only practical if you always have the remote in hand. Not practical if want to set the temperature and go about your business, like sleeping. I will have to buy a new motherboard and controller to make it as good as the basic/cheaper diesel heaters. Update... the motherboard went up in smoke already. I installed an after market motherboard and controller and then discovered that one of the magnets in the fan blade was just a piece of steel, I removed a magnet from an old fan and placed it into this units fan. This is for the hall effect sensor to work on normal motherboards. This heater came with a non traditional type motherboard. All fixed now and also replaced noisy fuel pump with a silent one. You need a little know-how to make this heater work properly.

Fan motor quit after a month, no way to contact seller for replacement parts.
