Yes! All Webasto heaters are tested and approved to work reliably up to 1,500m which is sufficient for most European mountains. The Air Top Evo and Dual Top Evo range even work up to 2.200m thanks to the integrated automatic altitude sensor. On request, the Air Top 2000 ST is equipped with an integrated switch for altitude operation of up to 2,200m.
For altitudes above 2,200m it is possible to adjust Webasto heaters. Please contact your local Webasto dealer for further details.
Passing over the mountains while the heater is in operation, is not a problem for any of the Webasto heaters.
