Cowlitz County winters push your water heater hard
Homes here need heat from September through June, ten months a year, and that means cold ground water coming into the tank most of the year. Winter nights average 33°F from December through February, and the colder that incoming water is, the longer the burner or element has to run to bring it up to temperature. That extra runtime wears on the heating element in an electric unit or the burner assembly in a gas one.
The county has seen six winter storms and five damaging wind events over the past ten years, and statewide, close to a quarter of households lost power for a full day or more in 2024. Most electric water heaters start back up on their own once power returns. A gas water heater with a standing pilot keeps running through the outage itself. But if a storm damages a vent or cuts gas to the house, that is when a homeowner notices, no hot water at the tap when it is needed most.

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, where sediment builds up over the years and corrodes through the steel. Once a tank starts leaking this way, it cannot be sealed or repaired, only replaced. Water at the bottom can also come from a loose drain valve or a fitting above the tank dripping down, so it's worth checking those before assuming the tank is done. A contractor can tell you which one you're dealing with.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and is no longer sensing that the pilot is lit, so the gas valve shuts it off. A weak pilot flame, a draft in the area, or a dirty pilot orifice can cause the same thing. This is a common repair on older gas water heaters and doesn't usually mean the tank is failing. A contractor can test the thermocouple and replace it if that's the cause.
- Can a tankless water heater be repaired?
- Yes, most problems on a tankless water heater are repairable. The igniter, the flow sensor, and the heat exchanger can all be tested and replaced individually rather than swapping the whole unit. Mineral buildup inside the heat exchanger is a common issue and can often be flushed out. A contractor can diagnose which part is causing the problem.
