Coolant Heating Solutions

Cold weather makes it tough to get bus engines started. Cold starts mean engine wear, increased maintenance costs and unnecessary idling. This is a challenge that all school bus fleets face, that's why Webasto developed the Scholastic Heater Series, products made specifically for the school bus industry. 

Webasto Scholastic Heaters pre-condition the buses engine helping to reduce fuel costs and down time, due to engine and DPF maintenance commonly attributed to excessive idling.
