The cover includes heat insulation material covering substantially all of each inside surface of each wall. A hinge pivotally mounts the roof to rear wall and a hinge pivotally mounts each side wall to the rear wall. Bolt fasteners removably attach the front wall between the side walls. A heating element is disposed within the housing. The front wall includes an upper panel and a lower panel mounted together by a hinge in a manner to allow the upper panel to be foldable outwardly and downwardly to position the outside surface of the upper panel against the outside surface of the lower panel.
