Description
We encourage you to watch our detailed Webasto heater installation and tips & tricks video.
If you're tempted to purchase your Webasto heater at a ridiculously low price from other online retailers, you should be aware that these are often European origin kits that are not compatible with all the North American parts and do not include some important parts. We have an extensive blog post about this here.

For your safety we recommend that you install a carbon monoxide detector in your van anytime you have any fuel burning appliance like a Webasto heater or propane cooktop. They are widely available. We sell this combination CO2 and propane detector.
About the Fan
Webasto heaters have a variable speed fan that runs continuously when the heater is on. It runs very slowly when not heating and ramps up speed when heating. If you have a SmarTemp digital controller you can use a "fan only" mode.

High Altitude Information
This Air Top 2000 STC is Webasto's smallest heater which is a great form factor for a camper van and is generally plenty powerful to keep you warm (2 kilowatt heating capacity). However, the small burner on these heaters is susceptible to excessive carbon build up - particularly the gasoline models. Diesel fuel is more forgiving in this context. Webasto has designed this heater to work optimally up to 4,900 feet altitude. If you're going to be spending a lot of time at higher elevations you should consider using the larger Air Top EVO 40 heater (4 kilowatt heating capacity) which is physically larger and therefore has a larger burner chamber which enables it to be used up to 7,200 effectively without the risk of carbon buildup issues and has "automatic" altitude adjustment capability. It's worth noting that Espar does not sell at 2 kilowatt heater - they're smallest gasoline heater is the B4 which is a 4 kilowatt heater that is similar to the Webasto EVO 40. So, while the Air Top 2000 STC will work at higher altitudes for shorter periods of time but Webasto does not recommend it and, if you do, you should run the heater at "full load" (turned up all the way) when you return to lower altitudes for at least a few hours in order to try to clean out the burner chamber. By the way, the EVO 40 uses the exact same mounting plate and "bolt pattern" for installation. So, if the larger form factor fits into your installation location you can put an EVO 40 into the same place as an Air Top 2000 STC.
New: Professionally, High Altitude Adjusted Webasto Heaters
Starting in October 2022, we began selling professionally pre-adjusted Air Top 2000 STC heaters that configured for up to 6,400 feet in elevation. Please check out this post for more information and links to those products.
Want to learn more? We recorded a one hour video interview with a Webasto tech that has a lot of great information you can watch the full video or use this link to jump to the part of the video where we discuss using an Air Top 2000 STC at altitude. There is also a lot of information on the correct way to perform an altitude adjustment on an Air Top 2000 STC heater in this blog post.
Installation Guide
Other Parts You Might Need For Your Installation
We also sell a variety of helpful installation parts including ducting to mounting plates. If you plan on having more than one vent/louver from your heater's hot air outlet, you may want some "T" or "Y" fittings or ducting. This PDF file illustrates all the parts available from Webasto for this purpose which we can special order for you and you can check out our ducting/vent configuration tool.
