The desires of a travel enthusiast who values independence, autonomy and freedom are accompanied by the following amenities: a comfortably warmed interior, an extended relaxing hot shower and the availability of hot water for washing up. The Webasto Dual Top ST presents itself as an integrated heating system that heats both air and water, providing cozy warmth and continuous hot water in all seasons. This extremely efficient system has been specifically designed for external mounting to provide additional storage space and increase personal comfort inside. On campsites with electricity, the variants of the Dual Top ST system can optionally be operated with electrical energy - either as a supplement to conventional use or even completely independently by power supply.
