We Fully Support DIY Installations! Unlike many authorized Webasto distributors, Vanlife Outfitters fully supports DIY installers. Our entire team has been trained to become Webasto certified "experts". Together with our distribution partner, we maintain a wide range products and replacement parts in-stock. If you experience a problem with your Webasto unit within the warranty period, we will work with you to determine the cause of failure and will either attempt to give instruction on how to correct any faulty workmanship or supply a replacement part. If a replacement part is needed we will send you the part immediately from their stock at no charge so that you can get up and running as quickly as possible. Of course, we rely on you to return any faulty parts in order to be reimbursed for the warranty repair.

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.
