Webasto Bunk Heaters for Semi Trucks

Webasto bunk heaters are built for heavy-duty use, but regular maintenance helps ensure reliable performance in extreme conditions. Annual service or inspection is recommended to check components like glow plugs, burner chambers, gaskets, and fans so the heater continues to run efficiently and avoids unexpected downtime.

A Webasto heater warms the cab, bunk, or engine without running the main engine, which significantly reduces idle time. Less idling means lower fuel consumption and fewer cold starts, improving DPF performance and reducing particulate matter buildup that leads to frequent servicing.

It depends on how you use your truck. A Webasto coolant heater, like the Thermo Top C, pre-heats the engine for easier cold-weather starts and reduced engine wear. An air heater, such as the Air Top 2000 ST, is ideal for keeping the bunk and cab warm while resting without idling the engine. Many drivers choose based on whether engine protection or cabin comfort is the top priority.

Webasto heaters use a very small amount of fuel compared to idling the engine. Coolant heaters typically consume around one gallon of fuel per 10 hours, while air heaters use even less. This efficiency adds up to meaningful fuel savings over long periods on the road.

Yes. Webasto heaters are engineered to perform in extreme cold and heat. They deliver consistent, controlled heating that helps maintain ideal engine operating temperatures in winter while supporting reliable travel year-round, even in harsh environments.

Professional installation is strongly recommended. Certified technicians ensure the heater is installed correctly, operates safely, and delivers maximum performance. Proper installation also helps prevent premature wear and ensures the system functions as intended throughout the winter season.
