ABSTRACT:
A heating system includes fluid ducts at the surface of a road and heating fluid for deicing the road surface when circulated through the ducts. A pump device for circulating the heating fluid through the fluid ducts to deice the road surface comprises a fluid pump housed beneath the surface of the road and coupled to the fluid ducts. The fluid pump has a piston and an actuator plate coupled to the piston. The actuator is pivotally mounted at the surface of the road in a manner whereby the weight of a vehicle passing over the actuator plate operates the pump device to circulate the heating fluid through the fluid ducts.
