Portland's long cold season and outages wear on a water heater
Your water heater works nine months a year here, October through June. On winter nights averaging 34°F, the water coming into the tank is cold, and the burner or heating element has to run longer to bring it up to temperature. That extra runtime wears on the thermostat and the heating element in an electric unit, or the burner assembly in a gas one.
Multnomah County has had 29 winter storms and 17 damaging wind events over the past ten years, and power does not always hold through them. In 2024, 20% of Oregon households went at least 24 hours without power. An electric water heater usually comes back on by itself once power returns. A gas unit with electronic ignition may need to be relit by hand. If yours has a standing pilot, it keeps running through the outage, and you will only notice trouble if the pilot itself has gone out.

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 tank itself has likely rusted through and is starting to fail. Water heaters corrode from the inside as the glass lining wears down and the steel tank underneath gives way, and once that happens the leak will not stop or get better. It can also be a loose drain valve or a fitting at the bottom, which a contractor can check before assuming the tank is done. If the leak is coming from the tank body, the water heater needs to be replaced.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out or sits out of position, it shuts the gas off even though the flame is lit. A dirty pilot orifice or a draft near the burner can cause the same problem. A contractor can test the thermocouple and clean or replace the part that is failing.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Mineral buildup on the heat exchanger is common and is cleared with a descaling flush, and parts like the igniter, flow sensor, or exhaust fan can be replaced on their own. A contractor can run the unit's error code and pin down which part is causing the trouble.
