The heater can be attached to a piping system to dry interior walls and/or heat coatings in the piping system. The heater can be attached to a manifold having alternative inlet end and two outlet ends. The manifold ends can have quick connect fittings with similar fittings to be easily mateably attached by rotating fittings with one another. A quick connect/disconnect air pressure regulator with quick connect fitting can be attached to the manifold ends. A quick connect/disconnect plug with similar quick connect fitting can close the manifold ends. ## Claims ### Claim 1 A portable heating apparatus, comprising: a portable heating chamber with a heating element having a single inlet end for directing air into the chamber and a single outlet end for emitting heated air therefrom, the chamber providing one path of air flow between the single inlet end and the single outlet end;
