Abstract
A system for heating conveyors which extend outside a wash tunnel of a carwash utilizes concrete structural slabs with heating apparatus embedded in the slab near a top surface and supported adjacent the conveyor. The heating apparatus can be a hydronic system or an electric heating mat embedded in the slabs which prevents water on the slabs or the conveyor from freezing in low ambient temperature conditions.
