Electric Water Heater Installation and Repair

Installing or repairing an electric water heater can improve home comfort and energy efficiency, but it also involves electrical work and plumbing. This guide lays out practical steps, common issues, and safety reminders to help you decide when to DIY and when to call a licensed pro.

Why choose electric water heaters The vast majority of homes use electric resistance heaters or heat pump water heaters, valued for reliability and ease of installation compared with gas units. Electric models require a dedicated circuit, proper wiring, and correct venting practices where applicable.

Before you begin Determine the unit type, capacity (in gallons), and energy factor. Check local codes and the water heater’s manual for wiring diagrams, breaker sizing, and installation clearances. Gather tools: adjustable wrench, pipe wrench, Teflon tape, pipe cutter, voltage tester, pipe insulation, and a bucket for leaks.
