Product Description

The AO SMITH 100108283 is a high-watt density screw-in replacement element for residential and light commercial electric water heaters. Rated at 4500 watts and 240 volts, it delivers reliable heating performance in standard tank-style water heater applications. The element measures 11 inches in length and features a zinc-plated construction for corrosion protection. A gasket is included to ensure a proper seal at installation. This element is a direct screw-in style, making it a straightforward replacement for licensed plumbers and HVAC service technicians working on electric water heater systems.

This element is suited for residential and light commercial electric water heater installations where a high-watt density screw-in style element is required. High-watt density elements concentrate heat output at the tip of the element, which helps reduce mineral scale buildup compared to low-watt density designs. Typical installations include standard 40- to 80-gallon tank-style electric water heaters found in homes, apartments, and small commercial buildings.
