Webasto Heating systems are priced on the site NOT INCLUSIVE OF INSTALLATION. Installation is additional cost based on our installation territory. Webasto Heaters warranty is only valid after having gone through an official commission procedure (It is included with our installation or available at $500 within our service territory for self installations). This commissioning involves a physical verification of the installation as well as a diagnostic tool scan for proper sensor and installation protocols. We then record the serial number as commissioned with Webasto for warranty confirmation.
