Independent heated hose

A method of operating a plural component dispensing system configured to mix a first fluid component and a second fluid component into an activated plural component material, the method comprising:

• transferring, by a controller, electric current from a power source to a first heating circuit of a first heated hose for a first on time period;
• transferring, by the controller, the electric current from the power source to a second heating circuit of a second heated hose for a second on time period;
• and
• alternatingly powering the first heating circuit and the second heating circuit such that the first on time period alternates with the second on time period, such that the first heating circuit is powered while the second heating circuit is depowered.

An electrically heated hose assembly comprising:

• an inner tube, the inner tube defining a flowpath for fluid to flow from a first end of the inner tube to a second end of the inner tube;
• a first heating circuit comprising:
• a first wire extending from the first end of the inner tube to the second end of the inner tube;
• a second wire formed separately from the first wire and electrically connected to the first wire, at the second end of the inner tube, the second wire extending from the second end of the inner tube to the first end of the inner tube;
• and
• a sheath disposed about the inner tube, wherein at least one of the first wire and the second wire is disposed radially between the inner tube and the sheath;
• wherein the first wire extends from a controller to the second end of the inner tube and the second wire extends from the second end of the inner tube to the controller.
