A.o. Smith 100108510 Screw-in Water Heater Element 4500W 480V

Product Description

The A.O. SMITH 100108510 is a high-watt-density screw-in replacement heating element designed for electric water heaters in residential and light commercial applications. Rated at 4500 watts and 480 volts, this element measures 10.75 inches in length and delivers reliable heat transfer for standard tank-style water heater systems. The zinc-plated construction provides corrosion protection for extended service life in direct-contact water environments. A gasket is included, supporting a complete, ready-to-install assembly. Licensed plumbers and water heater service technicians are the primary installers for this type of element.

This element is suited for residential and light commercial electric water heater tanks that use a standard screw-in mounting configuration. The 480-volt rating targets light commercial or higher-voltage residential systems rather than the common 240-volt residential setup, making voltage verification a critical step before installation. It is appropriate for service and replacement work on tank-style electric water heaters where the existing element shares the same wattage, voltage, and physical dimensions.

Key Features

• High-watt-density design for efficient heat transfer in electric water heaters
• Rated 4500 watts at 480 volts for light commercial or higher-voltage residential systems
• 10.75-inch element length for standard screw-in water heater tanks
• Zinc-plated construction resists corrosion in wet, direct-contact environments
• Gasket included for a complete, leak-ready installation
• Screw-in mounting for straightforward removal and replacement

Compatibility

Designed as an OEM-style screw-in replacement element for residential and light commercial electric water heaters requiring a 4500-watt, 480-volt, 10.75-inch high-watt-density element with standard screw-in fitment.

Installation Notes

Installation should be performed by a licensed plumber or qualified water heater technician. Always shut off electrical power at the breaker and close the cold-water supply valve before removing the old element. Drain sufficient water from the tank to expose the element port before removal. Confirm that the tank voltage matches the 480-volt rating of this element before completing the installation, and torque the element according to the water heater manufacturer's service documentation.
