A.o. Smith 100109765 Screw-in Element 5500W 240V

Product Description

The A.O. SMITH 100109765 is a low-watt-density, screw-in water heater element designed for residential and light commercial water heating applications. Constructed with Incoloy nickel-alloy sheathing, this element operates at 240 volts and 5500 watts while distributing heat across a larger surface area than standard elements. The lower watt density reduces scale buildup and extends service life in both hard and soft water conditions. A gasket is included with the element, supporting a complete installation without sourcing additional hardware. This part is installed by licensed plumbers and HVAC technicians performing water heater service or element replacement.

This element is suited for residential tank-style water heaters and light commercial units that accept a standard screw-in element configuration. It is a practical choice in installations where water quality or extended service intervals make low-watt-density construction preferable over standard-density alternatives. The nickel-alloy sheath resists corrosion and performs reliably across a wide range of water chemistry conditions.

Key Features

• Incoloy nickel-alloy sheathing for corrosion resistance and long service life
• Low-watt-density design reduces scale accumulation and extends element longevity
• Rated at 5500 watts and 240 volts for standard residential and light commercial service
• Screw-in mounting configuration for straightforward field replacement
• Gasket included for a complete, ready-to-install package

Compatibility

Designed as an OEM-style replacement screw-in element for residential and light commercial tank-style water heaters accepting a standard screw-in element at 240 volts and 5500 watts.

Installation Notes

Installation should be performed by a licensed plumber or qualified service technician. Before servicing, shut off electrical power to the water heater at the breaker and close the cold water supply valve. Drain sufficient water from the tank to expose the element before removal. Follow all applicable local plumbing codes and manufacturer guidelines when torquing the element and reconnecting wiring.
