Webasto Air Top 2000 Install

After doing an inspection and some minor repairs on the original Eberspacher heating unit I decided to err on the side of caution and installed a new 2KW Webasto 12V gasoline Air Top 2000 in its place. I already had a 60A step-down converter installed for the EZ PS, so I pulled from that for the heater (if you don't already have a 12V converter for accessories, then a small inline unit will get the job done inexpensively). The heater is plumbed directly to the main tank, because EFI, but if you're carbureted then a T off of the main fuel line will function as the original Eberspacher setup did. Both the fuel pump harness and the heater control harness have enough length to mount literally anywhere in a Pinz. The 3saurus mount adapts the Webasto (should also fit Espar and Chi heaters) to the original K ducting, which allows the Webasto to function perfectly as a bunk heater in my setup. The pics below should tell the rest of the story. Loving it! :D

Whether you go with an Espar, Webasto or Chinese unit, I highly recommend reviewing and following the install, setup and operation tips in this article.

By the way, if you search eBay for "Webasto Air Top 2000" you should find a number of Russian sellers selling in the $600-$700 range with a "Best Offer" option. A $500-$550 offer should get you one of these heaters. It did for me. If you can find one, a 24V petrol Chinese heater is going to cost you the same.

The Webastos out of Russia seem to be new surplus as they ship without manuals, installation instructions, etc. However, I had great communication with the seller and got a sweet deal.

That looks great! Can you post more about where and how you mounted the controller?

My hardtop is new fabrication by Andre at Fat Fabrications due to some "unpleasantness"... Anyway, the new top has additional framing and reinforcements. The top has paneling in the interior upper corners that runs the length of each side in order to conceal electrical, etc. I mounted the heater controller on this panel in the rear section of the vehicle so it could be easily accessed from our sleeping area. Specifically, I ran the harness from the heater, under the lip of the cab wall using the wire retention clips (as did the original heater electrical), to the passenger side, up the wall and behind the aforementioned paneling.

The harness provided with the heater is long enough to fit the controller literally anywhere inside the truck.

I am resurrecting an old thread here to see how the Webasto heater is doing. Yes, life and procrastination has bitten me as the price on these have skyrocketed but i may still get one. I have read about some problems with sooting in the petrol model that have caused malfunction and/or high maintenance. Any issues after a year? Still recommend? Thanks!
