Ten months of cold water coming in
Centralia homes need heat from September through June, ten months of the year. That long stretch means the water heater is working against cold ground water most of the year, not just in a short winter. Winter nights averaging 31°F push that incoming water even colder, so the burner or heating element runs longer to bring it up to temperature.
That steady run time is what wears out a thermostat or heating element before its time. And power matters here too. Close to a quarter of Washington households went at least 24 hours without power in 2024. Most water heaters come back on by themselves once power is restored, but a gas unit with a standing pilot will need that pilot relit by hand.

A new water heater would cut about $280 a year off hot water for a typical Washington home.

Repair makes sense when an element, thermostat or gas valve has failed.
Replacement makes sense when the tank itself is leaking.
- Why is my water heater leaking from the bottom?
- The most common cause is the tank itself failing from the inside out. Sediment builds up on the bottom of the tank over the years, and it wears through the lining until the steel underneath rusts and gives way. Once a tank is leaking like this, it needs to be replaced, not repaired, because the damage is inside the steel. A leak can also come from the drain valve or a fitting at the top of the tank, and those can often be fixed without replacing the whole unit, so it is worth having someone check where the water is actually coming from before assuming the worst.
- Why won't the pilot light on my water heater stay lit?
- Usually it is the thermocouple. That is the small sensor that sits in the pilot flame and tells the gas valve it is safe to keep the gas flowing. When it wears out or gets coated in soot, it stops reading the flame correctly and the gas valve shuts off the pilot as a safety measure. It is a cheap part and a common repair. A weak or dirty pilot orifice can cause the same problem, so if a new thermocouple does not fix it, that is the next thing to look at.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. Mineral buildup on the heat exchanger is the most common issue, especially if the unit has never been flushed, and that can be cleared out. Igniter failures, sensor faults, and blocked intake or exhaust vents are also things a contractor can fix without replacing the unit. It is only when the heat exchanger itself has cracked or corroded through that replacement becomes the only option.
