The Webasto Air Top 2000 STC has been the best-selling air heater in the market for years. The unique combination of power, efficiency, customization, and affordability put the Air Top 2000 STC in the air heater hall of fame.

Before the release of the Espar Airtronic S3 B2L in 2022, the Air Top 2000 STC was the only 2KW gasoline heater for vans on the market. It still remains a community favorite, over a decade after it's original release.


The Air Top 2000 STC provides a 6,800BTU heat output, enough for most vans and campers.

The heater's compact dimensions make it ideal for installing under the passenger seat.

Wide availability of spare parts and install guides make the Air Top 2000 easy to maintain.

Fuel efficient, affordable, and long-lasting makes this Webasto gasoline heater a worthy investment.

Save on maintenance, fuel, storage, and campground fees thanks to an efficient and lightweight design

The GoSun Camp 365 off-grid trailer unfolds in under 10 minutes into a 100 sq.ft. spacious camper.

A built-in water purifying system and power station to store solar energy let you stay on the road for longer.

This off-grid camper includes all the household appliances for comfortable living on the road.


11 years after the initial launch, the Air Top 2000 STC is still flying off the shelves. Over it's lifetime, this Webasto gas heater has built a true cult following.

Reliable, fuel-efficient, powerful, and affordable, the Air Top 2000 seems flawless. And once it's yours, the internet will help you fit it to any build. While the wide availability of aftermarket parts means that you'll never have to wait long if something breaks.

Guides ranging from regular installations to altitude modifications give you complete freedom to customize as you see fit. Keep in mind though, that some internal modifications may void the warranty.


The Webasto Air Top 2000 uses as little as 0.03 gal/h to keep your cabin warm. You can run it all night long, and not worry about the heater draining your fuel tank.

It's 3,000-hour lifespan can be extended with proper maintenance and regular cleaning. Most spare parts can be replaced, which means that the Air Top 2000 can literally last you for years.

Additionally, you can easily transform the Webasto gas heater into a bunk heater with just a few hot air ducting accessories.


The original Webasto gasoline heater comes with an integrated thermostat for temperature control. But for extra comfort, the Air Top 2000 is also compatible a Rheostat, Multi-controller, ThermoConnect, ThermoCall, and UniControl.

Finally, if you want to scale mountains you can do so with the Air Top 2000. The factory altitude limit is 5,000ft (1,500m), but this can be manually adjusted to reach even higher peaks (do so at your own discretion).


You have everything you need to get started in the Air Top 2000 STC kit, including a controller of your choice. We include all the necessary brackets, clips, screws, air ducting, and more, so you don't have to worry about it.

If you would like something added to your kit, you always reach out to our highly-trained support team. They will gladly advise you on anything you may need for your specific conversion, and help you make the right choice.


Compact dimensions ensure an easy installation anywhere in your cabin.

Integrated temperature sensor for improved temperature control.

The Webasto Air Top 2000 operates reliably at altitudes up to 5,000 feet.

Highly customizable with a wide range of controllers and parts from previous generations.

Innovative design and super efficient solar-powered appliances.

Durable and lightweight all-aluminum frame is immune to mold or rust.

A complete electricity system, powered entirely by solar panels.

100 square feet of customizable open space to fit all your needs.

    Webasto Air Top 2000 STC

    Posted by Zach F on 12th Sep 2021

    Heater works very well. No regrets from this purchase. Installation was a little rough with no directions. Had to try and piece it together from youtube videos of others doing it.

    Works amazingly!

    Posted by Troy on 13th Apr 2021

    With all the youtube videos available the install was extremely easy!

    What would be an amazing option is a auxiliary fuel option, like the RAM Promaster, so we can buy the parts from Heatso instead of the hardware store.

    Besides that from shopping, to purchasing, to receiving, to install it all worked great!

    Works well. Was a relatively easy install (directions aren't good there are some pretty good guides on youtube and the web). Arrived quickly and works as advertised.
