Get replacement water heater elements from Grainger to help keep electric water heaters in good repair. Elements are copper sheathed and zinc plated to help minimize galvanization that can limit their service life. High-watt density elements can be effective in areas with normal water hardness and minimal mineral content. Use low-watt density elements in moderately hard water. In areas with extremely hard water and high sulfur and lime content, choose nickel-based alloy sheath water heater elements. Find them all at Grainger!
