Electricity heats more occupied homes in Mohave County, Arizona than any other fuel, at 58.0% (2020-2024 ACS 5-year). An electric water heater has no burner, no flue, and no combustion air to account for, so when one fails in Mohave County a contractor's attention goes straight to the heating elements and the thermostats that control them. Sediment buildup accelerates element failure by forcing them to work harder against an insulating layer at the bottom of the tank. A contractor pulls the lower element first because it burns out before the upper one does, and what they find there tells them whether the fix is a single part or whether the tank's age has spread the damage further.
Water heaters in housing stock this old run on parts whose supply chain has narrowed since they were manufactured. Half the homes in Mohave County, Arizona were built in 1995 or earlier (2020-2024 ACS 5-year). When a contractor opens a unit and identifies the failed component, the next question is whether that part is still made in a matching specification or whether a substitute requires additional work to fit. That answer shapes the repair scope more than the fault itself does.
The Parts of a Water Heater a Contractor Checks During a Repair
The tank itself is the piece a homeowner sees first, usually standing in a utility closet, garage, or basement. It holds and heats the water. When repairs are needed, the tank's condition and what surrounds it tell a contractor a great deal about where the problem started.
The burner assembly or heating element sits inside or beneath the tank depending on whether the unit runs on gas or electricity, and the thermostat rides alongside it to control temperature. The pressure relief valve mounts on the side of the tank and releases if pressure builds too high. The anode rod runs down through the top of the tank and slows corrosion from the inside.

Extreme weather puts real stress on water heaters, pushing them through temperature swings and demand spikes that wear components faster than ordinary use does. How often that happens in Mohave County shapes how hard local units work and what kinds of repairs come up most.
