Abstract: A modular heater assembly includes resistive heaters disposed along sections of a fluid conduit system, insulation members around the resistive heaters, and at least one insulation block around a fitting. The fitting is configured to join at least two adjacent sections of the fluid conduit system and defines an exterior geometric profile. The insulation block includes a central recess extending axially in a direction of one of the at least two adjacent sections and defining an internal geometric profile substantially matching the external geometric profile of the fitting, and a peripheral aperture. The peripheral aperture is open to the central recess, defines an internal geometric profile substantially matching an external geometric profile of another of the at least two adjacent sections, extends through a sidewall of the insulation block, and is axially aligned with the another of the at least two adjacent sections.
