Product Description

The AO SMITH 100299123 is a heating element kit rated at 15 kilowatts and 208 volts, designed for use in electric water heaters operating on single-phase or three-phase power supplies. This kit provides the core resistance heating component responsible for transferring thermal energy to the water supply within the storage tank. It is a direct replacement part intended for installation by licensed plumbers or water heater service technicians working on commercial or residential electric water heater systems. The 15kW output makes this element appropriate for high-demand applications where recovery speed and heating capacity are critical operating requirements.

This heating element kit is suited for electric water heater installations where 208-volt service is present, covering both single-phase and three-phase configurations. High-demand commercial environments such as laundries, restaurants, multi-unit residential buildings, and light industrial facilities commonly require heating elements in this power class. The kit format typically includes the element and associated hardware needed for a complete serviceability replacement, reducing the need for separately sourced components during a repair call.
