ABSTRACT:
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 facilitates connection of electrical conductors (E) to the heater regardless of its location. A base (12) has an opening in which the fitting is received. The base is positioned against the sidewall when the heater is installed. A cover (36) is sized to fit over the base and attaches thereto. The base has an opening (22) therein through which the electrical conductor is routed for connection to an outer end of the heating element. A ring (26) is used to attach the heater to the base. The baseplate captures the one end of the fitting so the base is freely rotatable with respect thereto. Rotation of the base positions the cover so the conduit opening is readily accessible to an installer thereby to facilitate connection of the conduit to the heating element regardless of the heater location.
