Camco 2922 Screw-in Water Heater Element 4500W 240V

Product Description

The CAMCO 2922 is a screw-in, foldback-style electric water heater element rated at 4500 watts at 240 volts and 3500 watts at 208 volts. Constructed from Incoloy with nickel and chromium composition, this element is engineered for residential electric water heaters where lime and mineral scale accumulation is a recurring service problem. The ultra-low watt density design spreads heat across a larger surface area, reducing scale adhesion and extending service life compared to standard-density elements. One gasket is included. Plumbers and water heater service technicians install this element as a direct replacement in screw-in port tanks.

This element is suited for residential electric water heaters with a minimum tank diameter of 14 inches. The Lime-Life designation identifies it for use in hard-water environments where calcium and mineral deposits typically shorten standard element life. The foldback form factor allows installation in tanks where a straight or U-shaped element would not clear the tank walls. It is sold in bulk packaging with 25 units per standard carton, making it a practical stocking item for service shops and supply houses.

Key Features

• Ultra-low watt density reduces scale buildup and extends element life in hard-water conditions
• Incoloy construction with nickel and chromium resists corrosion and heat fatigue
• Foldback design fits tanks where straight elements cannot be installed
• Rated 4500W at 240V and 3500W at 208V for dual-voltage compatibility
• Withstands dry firing, providing a margin of protection during accidental no-water startup
• Includes one gasket for a complete installation

Compatibility

Designed as a screw-in replacement element for residential electric water heaters with a minimum tank diameter of 14 inches. Identified as a Lime-Life series component suitable for hard-water service applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified water heater technician. Disconnect electrical power at the breaker and shut off the cold-water supply before removing the old element. Use an element wrench sized for the hex fitting to avoid damaging the port threads. Verify the new gasket seats properly against the tank flange before torquing and confirm the tank is fully refilled with water before restoring power to prevent dry-fire damage.
