Webasto Air Top 2000 STC Diesel Heater Kit - With Rheostat Controller

It’s easy to understand why the Webasto Air Top 2000 STC Diesel Heater Kit is one of the most popular 6800 BTU heaters among van lifers. First off, it’s an economical air heater, producing an hour of heating for only 0.28 liters of diesel. And it’s the ideal heating solution for traveling and camping. Certified for internal use and compact in size, it can be easily transformed into a Webasto bunk heater using the ducting routing that is included in the kit. Actually, it can be used to heat up to two areas. This air heater is so small and compact that you’ll find yourself to be able to mount it in even the smallest of spaces, such as underneath the passenger side seat.

This Webasto diesel heater gives you multiple mounting options - you can install it internally or externally, if you wish. It’s also perfect for most vehicle types and can even be used for marine applications (with additional Marine Kit). And this air heater comes with an integrated temperature sensor to give you better and more efficient temperature control. It’s also great for van lifers who like traveling at high altitudes, as the Webasto Air Top 2000 STC Diesel Heater Kit can operate at altitudes of up to 5000 feet (1500 meters), and with the integration of a rheostat, it can function at even higher altitudes.

In fact, you’ll find everything you need in this simple to install kit. And you need never worry about maintenance or parts. Webasto is a renowned German brand, with repair shops across the globe.
