Customer Reviews for Diesel Fuel Heater 12V 5KW For RV Trucks With LCD Switch & 1 Air Outlet

Had a small issue due to damage from shipping ! Seller remedies the situation within 48 hrs ! And e mailed me a copy of instructions! Outstanding ! And the heater works great !

I love my new heater this was great I did not have to spend hundreds of dollars to keep me warm woooo??

Really good product

Just showed up today. Fast shipping. Bought for my semi and will update once installed.

I was surprised by the durability of the casing of the heater. I have been running this for a few months now and no problems with the heater itself. The controller on the other hand leaves a bit to be desired.

Keeps my 36 year old 20' trailer toasty warm when it is in the 20s outside. Wish I had bought one sooner. Will be buying more for my shop and my new travel trailer.Update: I did have to replace the glow plug about a week after install. Outside of that it has been a great heater. It's been in the low 30F at night here all week, and it has had no problems maintaining 70F inside.

This is my second purchase from Happy Buy folks . I absolutely _ove the heater it_ performance and steady second season of use . Its an awesome dry heat which is very important to stop any mold issue , I had with propane heat .I use some Sea Foam Diesel treatment at start of season.I highly recommend these solid built heaters .Only issue I had was the fancy digital thermostat control just could not figure it out. So I bought a simple one with just a dial and off and on lol

Excellent 3kw heater for my van! Works just like all the videos say. Came with more clamps, tie wraps, screws and hose than I needed. I have solar and used a two gallon gas can for fuel. Highly recommend this heater.

Good value for money, helpful when needed too

This is true of all heaters, regardless of price. If the heater was banged around at all on shipping some important part clearances, like the tiny space between the spinning fan and the heater case, might have have changed since it was tested in China. So..before starting the unit, remove the cap on the air inlet fan, and make sure it spins freely with no noise. Use your finger to spin it. If you hear plastic on plastic rubbing, a noise like a spinning plastic fan hitting the plastic housing, you must fix the fan clearance problem, sand paper, shims, adjust fan on shaft, flex the plastic away a few times quickly until it warms and stays, or even use a hair dryer. Just make sure the fan spins silently before turning on.
