Happybuy 12V 5KW Air Diesel Heater for RV Bus Motorhome Boat Car (Intelligent Voice Broadcast Diesel Air Heater with TG-Version Direct Connection to The car's own Fuel Tank)

I bought this heater for our homebuilt truck camper after having a similar name brand unit in a sailboat. The camper is a small pop up with canvas sides similar to a Four Wheel Camper. The heater blows 150* at the low setting. We camped in temperatures just below freezing and we turned the heater off because it worked so well. The install was pretty straightforward. The tank is sturdy steel and should last a long time. The heater started up and worked just like it should. The whole system survived a week of being driven and bounced around on rough gravel roads and trails. The unit itself if tiny and easy to find space to mount. I'm still curious as to how long it will last, but overall I'm more than happy with it!

I used this for my semi truck I'm an over the road driver so cabin comforts are important. 1 I found this unit easy to install even without receiving any instructions, and it has preformed beyond my expectations I have used it for 2 knights so far and on its highest setting it will run you out the truck I found the 2nd to lowest setting is best. 2 I only wish it came with instructions and a user Guide. 3 It was shipped really fast. Good job to the seller Thanks.

I bought this heater to install in my 5th wheel RV, as an auxiliary heating system to supplement the propane furnace. This heater functions properly, and seems to produce the required amount of heat. If you have researched this type of heater, you already may know that these heaters produce some combustion noise, but this heater dies not appear to produce any more noise than more expensive units. I suspect all of these aftermarket heaters are basically the same. So far, my heater does not smoke on start up or shutdown, and did not produce any combustion soot after running at a reduced load. I am happy with the heater performance and supplied accessories and installation hardware. The heater gets four stars because no instructions are included in the package. If you watch some of the online videos about parking heaters, you can easily determine how to install one if these units, but figuring out the controller functions can be difficult. I finally found a like controller for sale on another site with controller function instructions.

Product came as described. There are no instructions or no manual that came with a package. When asked for instructions, received generic manual that did not match product. When it was installed, I have an error code and nowhere to find description of that code. It will be good product if it will come with paperwork.

Arrived well packaged with no damage and no missing parts. Works perfect and was easy to setup. It's installed in my garage and vented through the outside wall. Will be purchasing another one for my Class C Motorhome when I can scrape together more money. Definitely recommend this heater.

The heater had a small problem that I had to fix but besides that it is a awesome heater! I’m going to buy another from them. I would highly recommend.

Considering the price is a 10th of what would pay for an Espar Airtronic I was thinking maybe it would be lacking in quality but I found the complete opposite as everything was packed super super nice and all the parts were put into quality bags separating them from the rest of the unit in the shipping box. I have not installed the unit yet but I can already tell the exhuast pipe isn't going to be long enough for the location I'm mounting it at to reach the outside of my van. besides that I have yet to test the functionallity but I will come edit my review when I do and add some more info.

Ordered during the holiday season and package delivered quick. The package included all items exactly as the photo shown. I installed it into a portable wood box for hunting camp and it worked as I expected. The starting current draw about 10 amp for short period and then dropped to about 3 when the control at highest speed, which can heat the ambient air of 55dF up to 100+. I let it run over night continuously for about 8-9 hours at low speed mode (2 bar from bottom) with about 0.7amp current draw and consumed about 1.5 liter fuel total. The noise level is pretty mild at lower speed. In general, it worked and the overall quality/workmanship looked "OK" per the price. For me, it will be once a year and 7 days usage, and I am pretty much satisfied for this purchase.
