A.o. Smith 100108440 Screw-in Water Heater Element 3000W 240V

Product Description

The A.O. SMITH 100108440 is a screw-in water heater heating element designed for residential and light commercial electric water heater service. Built with an Incoloy nickel-alloy sheath, it operates at 240 volts and 3000 watts, delivering a low-watt density output that reduces scale buildup and extends service life compared to standard higher-density elements. At 12 inches in length, it fits a wide range of tank configurations. A gasket is included in the package, making replacement straightforward for licensed plumbers and water heater service technicians.

This element is suited for residential and light commercial electric water heater applications where low-watt density performance is specified. Low-watt density elements are commonly selected in hard-water service areas or wherever extended element life and reduced mineral fouling are a priority. The screw-in mounting style is standard across a broad range of electric tank water heaters, and the included gasket eliminates the need for a separate trip to source one before the repair can be completed.

Key Features

• Incoloy nickel-alloy sheath resists corrosion and scale buildup in hard-water environments
• Low-watt density design extends element service life and reduces mineral fouling
• Rated 3000 watts at 240 volts for reliable heating performance
• 12-inch element length fits a wide range of residential and light commercial tank configurations
• Screw-in mounting style for straightforward removal and installation
• Includes gasket — no separate seal sourcing required before installation

Compatibility

Designed as an OEM-style screw-in replacement element for residential and light commercial electric storage water heaters requiring a 240-volt, 3000-watt, 12-inch element with screw-in mounting.

Installation Notes

Installation should be performed by a licensed plumber or qualified water heater service technician in accordance with local plumbing codes. Before service, shut off the electrical supply at the breaker and close the cold-water inlet valve, then drain the tank sufficiently to expose the element port. Use an element wrench for removal and installation — do not use pliers or adjustable wrenches, which can damage the hex fitting. Never energize the element while the tank is empty, as dry-firing will immediately destroy the element.
