Reliability

Velit air heater uses only high-quality and validated components to provide outstanding reliability. For example, it uses a Japanese glow plug with at least three times the lifespan compared to cheap ones. The controller is weather sealed to prevent water damage. 

High-Elevation Performance

With the built-in barometer, the Velit air heater has the industry's highest elevation rating (16000ft) so you will have warm air wherever you go. The barometer inside the controller senses the air pressure and adjusts the air-fuel mix ratio accordingly to provide better high-elevation performance and reduce carbon build-up.

Efficiency

The Velit air heater features a proprietary combustion chamber design that increases combustion efficiency. The exhaust temperature is 30% less than that of a cheap heater, meaning more heat is dissipated to the interior.

Quiet Operation

The blower fan is dynamically balanced and the pump frequency is three times lower due to higher volume per pump (65mL vs 22mL), resulting in a much quieter operation. It is so quiet that you will not even notice it so you can have a good night's sleep without being annoyed by the ticking sound of the fuel pump.

FAQs

Can I install an RV air conditioner myself?

While it is possible to install an RV air conditioner yourself, it is recommended that you hire a professional to ensure that it is installed correctly and safely.

Can I use my RV air conditioner while driving?

Yes, you can use your RV air conditioner while driving, but it is recommended that you only use it on generator power and not on battery power to avoid draining the battery.

What size RV air conditioner do I need?

The size of the RV air conditioner you need depends on the size of your RV and the climate in which you will be using it. A general rule of thumb is to have one 13,500 BTU air conditioner for every 350 square feet of living space.

Can I run my RV air conditioner on solar power?

Yes, it is possible to run an RV air conditioner on solar power, but it requires a large solar panel system and battery bank. It is also important to note that running an air conditioner on solar power may drain the battery quickly.

How often should I clean my RV air conditioner filters?

RV air conditioner filters should be cleaned or replaced at least once a month during heavy use to maintain proper airflow and performance.

Works as Advertised—Better than Webasto

We replaced a WebastoAT2000 with the VeLit heater. Because of the heat at lower elevations, the initial run was at 9,000 feet. In short, the VeLit works better—and quieter—at 9,000 feet than the Webasto did at sea level. We look forward to warmth at even higher altitudes. This heater is a game-changer.

Everything I was looking for

This heater checked all the boxes when I was researching. Installing a parking heater is a massive job for the DIY person and having installed a CDH in another van, I was convinced that it is well worth buying a heater with self adjusting altitude control and a real thermostat. I installed this unit and appreciated the small upgrades over the cheap CDHs like nicer tubing, clamps, and how the pump control wires don't need to be cut. I installed an espar stand pipe into the fuel tank (petrol) to avoid any issues at altitude. The included stand pipe seemed ok, but was a little rusty. It's worth the extra $30 for piece of mind.

The unit fired up second try, I did prime the line with vacuum. It runs quiet and the controller is very intuitive. I tested the CO content and it was below 14 ppm throughout the run. I'm stoked to leave that thing at home! No more getting out of the van in the cold to make sure I changed the settings correctly! I haven't run at altitude yet, but I'll try to update this review in a couple months when I try it! Overall, so worth the money. Super glad someone went through the effort to make an upgraded unit! Honestly the price for the espar or other name brand units with altitude adjust is insane and from my research they aren't much more reliable than a cheap Chinese unit.

Does the job great, a couple minor nitpicks

If you have a gas RV or other vehicle in need of an air heater, this is a definite recommendation as I can actually feel confident that I won't be replacing a cheaper diesel version every year, while still having the ability to only use one type of combustion fuel in my setup. More details and why I didn't give 5 stars (would have given 4.5) below.

Bought a pair of these to replace the propane furnaces in my vintage gas RV. Installed the first one about a month and a half after delivery, just in time to keep this drafty behemoth in the 60s Fahrenheit while it's barely in the teens outside. There are only a couple things that I think could be better, listed below:
-Fuel pump had some difficulty keeping gas fed at first, possibly due to my fuel line routing, could have a better setup for clearing the lines of bubbles
-Thermostat/control module plug is a bit too wide for a convenient install, could be set up more like the fuel pump wires with the connectors not in the plug body yet or using a smaller plug
-Since the heater can't be installed with the combustion intake/exhaust on the side, I had to put a new hole in the RV instead of reusing the factory furnace vents
-The 12V supply wires have the fuse almost at the battery end, meaning I had to splice the fuse back in after cutting off the excess length. Possible solution to have the 12V wiring harness be separated into a shorter section on the heater side with a longer section that can be plugged in with the ring terminals to reduce the required wire splicing

Great for the price

Finished installing yesterday. Heater works great and controller is basic but gets the job done. Only things I would like to see improved are actual rubber cable instead of taped wires for the harness and a silencer should be included. If it continues to work well it will be a solid deal at this price
