"I'm not at all concerned with the technology..."
Third case: You try to support your argument with technical performance data, but your fellow decision-makers have concerns for completely different reasons. For example: "My car gets warm anyway when I drive it, why should I burn extra fuel in the parking heater? That's not good for the environment!"
In this case, facts help. The fuel consumption of a consumption-optimized parking heater from Webasto is only about 0.3l for half an hour of warm-up time. A preheated engine avoids cold starts and thus prevents wear. In addition, the driver experiences a significant gain in comfort and safety.
Another argument for fellow decision-makers who are not convinced by the technical features is the improved driving safety. Statistically, most accidents in winter occur in the first 15 minutes after driving. The reasons for this are limited visibility and extended reaction times at low temperatures. The parking heater from Webasto offers more safety and more comfort on cold, wet days and in winter.
Clear windshields are an important safety feature that is achieved through parking heaters.
