A.o. Smith 100108803 Screw-in Water Heater Element 4500W

Product Description

The A.O. SMITH 100108803 is a mid-line screw-in flange specialty heating element designed for electric water heaters. Operating at 240 volts and 4500 watts, this element threads into the heater tank at the mid-body port, where it handles the primary heating load in standard residential and light-commercial storage-tank water heaters. At 12.1875 inches in length, the element reaches the appropriate depth within the tank to deliver consistent heat transfer. Installation is performed by licensed plumbers or qualified water heater service technicians during element replacement or initial unit commissioning.

This element is suited for electric storage-tank water heater applications requiring a screw-in flange mount at the mid-line position. The 1.375-inch screw-in flange interface is a widely used configuration in residential electric water heaters. It is appropriate for applications where the original element has failed due to scale buildup, burnout, or physical damage, and a direct-specification replacement is required to restore full heating capacity.

Key Features

• 4500-watt output at 240 volts for standard residential heating demand
• Screw-in flange design with 1.375-inch thread for secure tank seal
• Mid-line mounting position for effective tank-volume coverage
• 12.1875-inch element length sized for typical residential tank depth
• Specialty element classification for targeted replacement applications

Compatibility

Designed as an OEM-style screw-in replacement element for electric storage-tank water heaters requiring a mid-line 1.375-inch flange mount rated at 240 volts and 4500 watts.

Installation Notes

Installation should be performed by a licensed plumber or qualified water heater technician in accordance with local plumbing codes and the manufacturer service documentation. Always disconnect electrical power at the breaker and shut off the cold-water supply before removing the old element. The tank must be fully drained before the element is unthreaded to prevent water discharge. Use an element wrench to seat the replacement element to a proper seal without overtightening the flange threads.
