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

The Heater works Good. Mine came with an LCD controller that did not light up, the seller responded quickly and replaced the controller in a very short time. Very efficient heater. 40F inlet air discharges at 235F, surprised me to be such a raise in temperature. Just what I was looking for.

Love this little heater..

This little heater is amazing!! Thank you for quick response to replacing original unit that was "overly" challenging. Anyone have problems or need help troubleshooting this unit there are TONS of videos on youtube and facebook is loaded with helpful people. Look up Diesel heater pages. There are three or four of forums on fb. Answers in seconds or minutes~~

GREAT PRODUCT, EASY TO INSTALL,WORKS LIKE A CHAMP........ JEFF L

Great looking, impressed with the product appearance in the box. Webasto heater price three times higher, less features, comes in a box with less cushion prone to damages during shipping. Happybuy heater purchased to replace a Webasto heater dead after 7 years of service.I'm expecting to see it running for at least 3 years.

Finally a TRUE 2kw diesel heater....after receiving several that were not.Received the heater today and after connecting the fuel, electrical connections and exhaust I then primed the heater for about 20 seconds then switched it on.Runs great. Initially I had an air bubble in the fuel line and that caused some surging and a odd humming noise but once removed this heater ran like a champ. Quiet and smooth. Ran it for 3 hours and no problem. Great heater.One thing....it comes with a 12v 18.5-20 fuel pump and after searching for several days I cannot find this pump to order a replacement if and when i need it. Plenty 22ML pumps available but not one 18.5-20

Product preformed as advertised. Works great heating a garage with solar power. Low draw

My husband loves this he uses it in the garage

This product quit working after a couple of days. It provided good warmth. While it was working. I am happy to report that Happybuy did send me a shipping label to return the heater. I would recommend Happybuy.

best heater ever in my bluebird school bus
