Ao Smith 100108618 Copper Heating Element 4500W 240V

Product Description

The AO SMITH 100108618 is a copper heating element designed for electric water heater service. Rated at 4500 watts and 240 volts, this element transfers heat directly to the water inside the tank through resistive heating. At 8.125 inches in length, it fits the standard lower or upper element port found on residential electric water heater tanks. Plumbers and water heater service technicians install this element as a direct replacement when an existing element has failed due to scale buildup, burnout, or sediment damage. The copper construction provides reliable thermal conductivity for consistent water heating performance.

This element is suited for residential electric storage water heaters requiring a 240-volt, 4500-watt replacement element. It is appropriate for tanks where the existing element measures 8.125 inches in length and matches the K-style element configuration. Service work typically involves draining the tank fully or using an element changing tool that minimizes water loss before swapping the element.

Installation Notes

A licensed plumber or qualified water heater technician should perform element replacement. Before beginning, shut off the electrical supply at the breaker and close the cold water inlet valve to the tank. Drain the tank fully or use an element swap tool to reduce water loss, and use an element wrench to remove and install the element to avoid thread damage. Follow all applicable local plumbing codes during service.
