Truck & Bus

A school bus in 1942 that needed to stay warm over night was where HOTSTART began. The simple need to warm a bus without idling was the foundation for the engine heating products we sell today.

On-highway trucks and buses can reduce costly idling with the use of a simple threaded in-block immersion heater and thermocord. "Plugging in" during the night rather than idling reduces harmful emissions while keeping the engine ready to start when needed.

HOTSTART in-block heaters and thermocords are a cost-effective way to cut idling for trucks and buses operating during winter weather. Large fleet operations can see significant fuel cost savings when they heat their engines rather than idle. With the world relying on trucks to keep commerce moving, using HOTSTART engine heaters in cold weather helps maximize the bottom line.
