Rotatable heater housing

A housing (10) for use with an electrical heater (H) mounted on the sidewall (S) of a container (C) for heating a fluid (L) in the container. A heating element (R) is installed in a fitting (F), and the housing (10) facilitates connection of electrical conductors (E) to the heater (H) regardless of its location. A base (12) has an opening in which the fitting is received. The base (12) is positioned against the sidewall when the heater (H) is installed. A cover (36) is sized to fit over the base (12) and attaches thereto. The base (12) has an opening (22) therein through which the electrical conductors (E) are routed for connection to an outer end of the heating element (R). A ring (26) is used to attach the heater (H) to the base (12). The base (12) captures the one end of the fitting (F) so the base (12) is freely rotatable with respect thereto. Rotation of the base (12) positions the cover (36) so the conductor opening (22) is readily accessible to an installer thereby to facilitate connection of the conductors (E) to the heating element (R) regardless of the heater location.
