ABSTRACT:
A pipe heating apparatus for heating pvc pipe to facilitate bending. The pipe heating apparatus includes a housing having a lower portion and an upper portion, and at least one aperture extending through a wall of the housing. The lower portion includes a bottom wall for resting upon a horizontal support surface, and a lower perimeter wall extending upwardly from the bottom wall. Similarly, the upper portion includes an top wall and a upper perimeter wall extending downwardly from the top wall. The lower perimeter wall and the upper perimeter wall both have the same form and size. The upper portion may be positioned to rest upon the lower portion. Thus, an edge of the upper perimeter wall abuts an edge of the lower perimeter wall. The housing defines an interior space for receiving a portion of a pvc pipe.
