Air Heaters

Webasto air heaters are a great way to heat your cabin without needing to operate your vehicle engine, reducing vehicle idle emissions and minimizing engine wear. By tapping into the vehicle fuel tank, there is no need to worry about filling and monitoring an additional fuel source. Simply set the thermostat to the desired temperature and the heater will quietly and rapidly heat the interior cabin space. All Webasto air heaters come standard with a 2 year/2,000 hour warranty and industry leading technical support.

*Please note* There are a few versions of Webasto heaters being sold at reduced prices online. These vendors are typically selling European or Russian versions which have different required specifications and use different components which can only be sourced from its respective region. Here, we sell and work on the North American model.
