Electricity heats more occupied homes in Island County, Washington than any other fuel, at 57.9% (2020-2024 ACS 5-year). A water heater running on electricity puts its load on the heating elements and the thermostat, not on a burner, a gas valve, or a flue. When a contractor opens a failing unit in Island County, sediment on the lower element and a degraded thermostat are the first things they check, because those are the parts the work falls on. The service panel that feeds the unit was sized for an electrically heated home, so a replacement can step up in capacity without the fuel-conversion work a gas swap would require.

Water heaters in Island County housing get replaced and repaired on their own schedules, independent of what the walls around them were built for. Half the homes in Island County, Washington were built in 1991 or earlier (2020-2024 ACS 5-year). A house that old has seen several water heaters come and go, which means a contractor opening a failing unit is working with equipment whose age and condition have nothing to do with the age of the permit on the house. What they find inside determines the repair scope: whether a heating element or thermostat is still a stocked part, whether sediment has shortened what would otherwise be a straightforward fix, and whether the unit itself is worth repairing at all.

The Parts of a Water Heater a Contractor Checks During a Repair

The tank is the piece most homeowners recognize, a large insulated vessel that sits in a utility room, basement, or garage and holds water at a set temperature. When a repair call comes in, the tank itself is one place a contractor looks, checking for corrosion, sediment buildup, or a failing anode rod that sits inside it.

The burner assembly or heating element, depending on whether the unit runs on gas or electricity, sits at the base or within the tank and is the part that does the actual heating. A gas unit also has a thermocouple, a flue, and a gas valve, each of which a contractor checks when the unit fails to heat or shuts off unexpectedly. The pressure relief valve mounts on the side and is a common point of failure when water leaks appear.
