A.o. Smith 100108290 Screw-in Water Heater Element 240V 4500W

Product Description

The A.O. SMITH 100108290 is a zinc-plated copper screw-in water heater element rated at 240 volts and 4500 watts. Marketed under the Corrogard line, it features a mid-line design engineered for improved durability and a low watt density relative to its physical size. Low watt density reduces surface heat buildup on the element sheath, which helps extend service life in hard-water conditions. The element ships with a gasket included, simplifying the replacement process. It is a direct screw-in style, making it compatible with standard residential and light commercial electric water heater tanks that use threaded element ports.

This element is suited for residential and light commercial electric water heater applications. Plumbers and water heater service technicians install this part during routine element replacement on standard tank-style water heaters. The screw-in design is the most common element configuration found in North American residential storage water heaters, and the 240-volt, 4500-watt rating is among the most frequently specified combinations in that market segment.

Key Features

• Rated at 240 volts and 4500 watts for standard residential electric water heater circuits
• Zinc-plated copper construction provides corrosion protection inside the tank
• Low watt density design reduces sheath surface temperature and helps extend element life
• Screw-in mid-line style fits standard threaded element openings on tank-style water heaters
• Gasket included for a complete, ready-to-install replacement
• Suitable for residential and light commercial use

Compatibility

Designed as an OEM-style screw-in replacement element for residential and light commercial tank-style electric water heaters that accept a threaded mid-line element at 240 volts and 4500 watts.

Installation Notes

A licensed plumber or qualified water heater technician should perform this replacement. Before starting, 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 to remove the old element and install the new one with the supplied gasket seated properly to prevent leaks. Refill the tank completely before restoring power to avoid dry-fire damage to the new element.
