description A heater preferably having a plurality of equally spaced heating elements, such as heating lamps, provides a uniform heat radiation pattern for quickly and uniformly heating a large surface area using motor controlled wheels for translating the heater at a constant rate of speed across the surface of a structure in a desired pattern. The heater having a handle for operator manipulation for guiding and turning the heater in the desired pattern. The heater, having a wide lateral distance for radiating a wide uniform radiation pattern is suitable for thermographic application for imaging the heated surface and detecting subsurface defects in the structure, such as composite overwrapped concrete bridge and building structures subject where debonding of the composite/concrete interface is a concern.
