Lochinvar ER152 ASME Heat Exchanger w/Header (100147468)

The Lochinvar ER152 ASME heat exchanger with header is a major replacement heat-transfer assembly for a compatible ER152 heating system. It is not a small external fitting or complete replacement heater.

How This Component Fits the System

Pool and spa service parts play an important role in keeping an installed system maintainable. Selecting the right replacement can restore intended operation without discarding equipment that is otherwise in good condition. The most reliable approach is to identify the component by its actual function, compare it with the removed part, and use the manufacturer’s equipment diagram when different versions are available.

Confirm the exact boiler/heater model, heat exchanger revision, header connections, and applicable ASME specifications with the manufacturer before ordering or installation.

Replacement and Maintenance Considerations

A well-planned repair includes inspecting the condition of the neighboring assembly before reinstalling the replacement. Look for worn mating surfaces, loose retainers, damaged connections, corrosion, or other conditions relevant to the component being serviced. Recommission the system using the manufacturer procedure rather than assuming that installing a new part alone resolves the original operating problem.

For this particular listing, the ordering reference is 100147468. The identifying description is Lochinvar ER152 ASME Heat Exchanger w/Header (100147468). Matching the original unit and the manufacturer parts illustration is particularly important where closely related models have different mounting or electrical requirements.
