Ao Smith 100108954 Screw-in Water Heater Element 2500W 120V

Product Description

The AO SMITH 100108954 is a Corrogard zinc-plated copper screw-in water heater element rated at 2500 watts and 120 volts, measuring 8.125 inches in length. Designed for residential and light commercial water heaters, this mid-line element features a low watt density construction that reduces scaling and extends service life compared to higher-density alternatives. The zinc-plated copper construction provides corrosion protection suited to a range of water conditions. A gasket is included for a complete installation without sourcing additional sealing hardware. Licensed plumbers and HVAC service technicians are the primary installers.

This element is intended for residential and light commercial electric water heater applications where a screw-in style element is required. The 120-volt, 2500-watt rating makes it appropriate for smaller-capacity storage tanks or single-element configurations operating on standard household voltage. Its mid-line watt density is a practical choice for installations where water quality or tank longevity are considerations.

Installation Notes

Installation should be performed by a licensed plumber or qualified service technician.
