This element is suited for residential storage-tank water heater applications. It is designed as a universal replacement for flange-style elements found across a wide range of residential water heater brands.

The 240-volt, 3000-watt rating fits the most common residential single-element and dual-element configurations.

Installation should be performed by a licensed plumber or qualified service technician. Before beginning work, shut off power to the water heater at the breaker panel and close the cold water supply valve to the tank.
