Ao Smith 100108884 Screw-in Water Heater Element 4500W 208V

Product Description

The AO SMITH 100108884 is a 13-inch Corrogard zinc-plated copper screw-in water heater element rated at 4500 watts and 208 volts. Designed for mid-line installation, it operates at a low watt density relative to its size, which reduces scale buildup and extends service life inside the tank. The zinc-plated copper construction provides corrosion protection in a wide range of water conditions. A gasket is included for a complete, ready-to-install replacement. Licensed plumbers and HVAC technicians install this element during routine water heater service or as part of a full element replacement job.

This element is suited for residential and light commercial electric water heater applications. The screw-in mount is a standard configuration found in most tank-style electric water heaters. The low watt density design makes it a practical choice for installations where scale accumulation or hard water conditions are a concern. It is intended for systems operating at 208 volts, a common supply voltage in both residential multi-family buildings and light commercial settings.

Installation Notes

Installation should be performed by a licensed plumber or qualified water heater technician. Before servicing, shut off electrical power at the breaker and close the cold water supply valve to the tank. Drain sufficient water from the tank to expose the element before removal. Follow local plumbing codes and verify the supply voltage matches the element rating prior to energizing the circuit.
