Replacement Thermostat for 6E769 and 6E770

The Rheem SP8260 is a single-throw electric thermostat designed as a direct replacement for water heaters using part numbers 6E769 and 6E770. It fits plumbing drain components and carries the Rheem brand for OEM compatibility. Installers use it to restore factory temperature control on supported residential electric units.

Sustained Temperature Regulation

Under continuous operation the thermostat cycles the heating element to maintain water temperature between 90 and 150 degrees Fahrenheit. The single-throw mechanism opens and closes reliably during repeated heating cycles without drift. This behaviour keeps the tank within the set range during prolonged daily draw patterns.

Compatibility and Temperature Limits

The control range is fixed at a minimum of 90 degrees and a maximum of 150 degrees Fahrenheit, so systems requiring lower or higher set-points cannot use this part. It cross-references Grainger numbers 1PZ87 and 3WA66 through 3WA78 for identification. Buyers needing a different temperature span or a double-throw switch must select another model.
