Protects engine and saves fuel. The compact Thermo Top C water heater pre-heats the engine to the starting temperature. This considerably reduces the load on the engine caused by a cold start and thus increases the life span and operational readiness of the engine. Additionally, the parking heater Thermo Top C protects the environment, as avoiding engine idle run times reduces fuel consumption as well as CO2-emission. Ice and mist-free windows ensure safety right from the start thanks to a clear view.
