Corvallis water heaters work most of the year
Your water heater is doing something all winter, October through June, with cold ground water coming in and nights averaging 35°F. That is a long stretch for a tank to keep recovering, and the parts that manage the heat, the thermostat and the heating element or burner, are working most months of the year.
Power is the other piece. Twenty percent of Oregon households went at least a day without power in 2024. A gas water heater with a standing pilot will keep making hot water through an outage like that. One with electric ignition or an electric tank will not come back on until the power does, and most start up again on their own once it is restored.

A new water heater would cut about $390 a year off hot water for a typical Oregon 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?
- Most of the time it means the tank itself has rusted through and is failing. Sediment builds up on the bottom of the tank over the years, and it traps moisture against the steel until it corrodes. A leaking tank can't be patched or sealed, it needs to be replaced. It's worth checking first that the water isn't coming from a loose drain valve or a fitting above the tank, since those can be repaired. A contractor can tell you which one you're dealing with.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that sits in the pilot flame and tells the gas valve it's safe to keep the gas flowing. Once it wears out it can't hold that signal, so the valve shuts the gas off and the pilot goes out. A dirty pilot orifice or a draft in the area can also blow the flame out or keep it from reading right. A standing pilot doesn't use any electricity, so a power outage isn't the cause. A contractor can test the thermocouple and replace it if that's the problem.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Common issues are a clogged inlet filter, a buildup of scale on the heat exchanger, or a failed igniter, and all of these can be cleaned or replaced without swapping out the whole unit. The circuit board and sensors are also serviceable parts. A contractor can run the error code the unit displays and tell you what's actually wrong before deciding whether repair or replacement makes sense.
