What winter and power outages do to a water heater in Rowan County
Your water heater works harder from October through April, when incoming water runs cold and the tank has to make up more ground to hit temperature. On nights that average 31°F, that is seven months of longer burner cycles or longer element run times, and that wear adds up on the thermostat and the heating element or the burner assembly.
Power matters here too. A quarter of North Carolina households went at least 24 hours without power in 2024, and the county has logged 101 damaging wind events and 7 winter storms over the past ten years. Most gas water heaters with a standing pilot keep running through an outage, but electric units and gas units with electronic ignition go cold until power is back, and some need the pilot relit by hand. If your water heater does not come back on its own once the lights do, that is usually the ignition control or the thermostat, not the tank itself.

A new water heater would cut about $300 a year off hot water for a typical North Carolina 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 has rusted through from the inside and is failing. Sediment builds up on the bottom of the tank over years and traps moisture against the steel, which eats through it from the inside out. It can also be a loose drain valve or a fitting that has failed, which a contractor can tell apart from a tank failure by drying the area and watching where the water actually comes from. Once the tank itself is leaking, the water heater needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and stopped sensing the flame, so the gas valve shuts off to protect you. A dirty pilot orifice or a draft pulling the flame away from the thermocouple can cause the same thing. A weak or failing gas valve is possible too, though less common. A contractor can test the thermocouple's output and replace the part that is actually failing instead of guessing.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Mineral buildup on the heat exchanger, a failed igniter, a clogged inlet filter, or an error code from a sensor are all things a contractor can fix without replacing the unit. Whether repair makes sense depends on the age of the unit and which part has failed, which a contractor can tell you after looking at it.
