A heating apparatus for heating rigid plastic pipe for the purpose of bending and forming the pipe. The heating apparatus includes an elongate housing that has a bottom wall, a pair of side walls, a first end wall, and a second end wall to define an interior. Each of the end walls has a pipe hole for permitting a user to insert rigid plastic pipe through the interior. An elongate burner member burns combustible gas to produce heat and is mounted to the housing and is positioned in the interior proximate to the bottom wall. A valve assembly regulates a flow of the gas to the burner member. An elongate burner plate disperses the heat generated by the burner member and is positioned above the burner member. A plurality of pipe support members support the pipe above the burner plate while positioned in the interior of the housing. An elongate cover member selectively covers the opening to the interior of the housing.
