The ProAir 65,000 BTU Low Profile Floor Heater is a high-output, heavy-duty auxiliary hydronic cabin heater utilized extensively across commercial shuttle buses, school buses, and paratransit vehicles. Engineered to mount discreetly beneath passenger seats or along the interior floor wall, its compact 7.5-inch height maximizes passenger legroom and aisle clearance without sacrificing heating power. Connecting directly to the vehicle’s engine coolant loop, this unit utilizes a high-efficiency copper/brass heater core paired with dual 12V blower assemblies to push 640 CFM of warm air across the cabin floor. Because heat naturally rises, floor-mounted units are the most effective way to eliminate cold spots and keep up to 30 passengers comfortable during freezing winter routes.
