Stationary heating systems are essential in trucks, especially on long-distance and winter routes where drivers need to take rest periods. These systems allow the vehicle interior to be heated without the engine running, reducing fuel consumption and engine wear. Stationary heating systems ensure comfort and warmth inside the truck cab, regardless of the outside temperature. They usually run on diesel fuel and include a small heater that can maintain the temperature safely and efficiently. Regular maintenance is essential to ensure reliable operation and long life.
