Abstract
Devices, apparatus, systems and methods of using a portable heater that does not use a separate compressor or blower or vacuum. 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.
