Kanawha County winters put real strain on a water heater
Your water heater works harder from October through April, when incoming water runs cold and winter nights average 27°F. The burner or heating element has to run longer to make up that difference, and that extra runtime wears on the parts that do the heating. On a gas unit the igniter and burner assembly take the hit. On an electric unit it is the heating element and the thermostat controlling it.
Power is part of it too. Statewide, over a third of households went at least a day without power in 2024, and this county has seen 16 winter storms and 259 damaging wind events over the past ten years. When power drops and comes back, an electric water heater simply resumes heating on its own. A gas unit with an electronic ignition needs that ignition system working to relight, and if it does not, you are left with cold water and no hot water on demand until it is repaired.

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 probably rusted through. Water heater tanks are lined, and once that lining fails, the steel underneath corrodes and eventually lets water seep out at the bottom. It can also be the drain valve or a fitting that has loosened, so it is worth checking those before assuming the tank is done. A tank that is actually leaking from a rust hole cannot be patched. It needs to be replaced.
- Why won't the pilot light on my water heater stay lit?
- Usually it is a weak or dirty thermocouple, the small sensor that tells the gas valve the pilot is burning. If that sensor is coated in soot or has drifted out of position, it reads the flame as out and shuts the gas off even while the pilot is lit. A draft blowing across the pilot can cause the same thing. If relighting it does not hold, the thermocouple or the gas control valve needs a look from a contractor.
- Can a tankless water heater be repaired?
- Yes, most problems on a tankless unit are repairable. Mineral buildup on the heat exchanger, a failed igniter, or a clogged inlet filter are common and a contractor can flush or replace those parts. Error codes on the display usually point straight to the cause. Whether repair makes sense over replacement depends on the age of the unit and what a contractor finds once they open it up.
