What winter and outages do to your water heater here
Moundsville needs hot water for showers and dishes every day of the year, but the water heater works hardest from October through May, when incoming water is coldest and the tank runs longer to keep up. That extra runtime wears on the heating element in an electric unit or the burner assembly in a gas one. Those are usually the first parts to give out.
Marshall County has had 8 winter storms and 36 damaging wind events over the past ten years, and statewide more than a third of households lost power for at least a day in 2024. When the power drops, an electric water heater stops heating until it comes back. A gas unit with an electric igniter won't light either. Either way you notice the same thing. You turn on the hot water and nothing happens.

A new water heater would cut about $70 a year off hot water for a typical West Virginia 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 often the tank itself has rusted through and is starting to fail. Water heaters corrode from the inside over the years, and once the tank wall is breached, no fitting or valve will stop the leak, because the metal itself has failed. It can also be the drain valve at the bottom, or a fitting that has loosened, and those can sometimes be replaced. A contractor can tell you which one you are dealing with, since a leaking tank means replacement while a leaking valve does not.
- Why won't the pilot light on my water heater stay lit?
- The thermocouple is usually the reason. It is the small sensor that sits in the pilot flame and tells the gas valve the pilot is lit. When it wears out or sits out of position, the gas valve shuts the pilot off as a safety measure even though you just relit it. A dirty pilot tube or a draft blowing across the flame can also cause it, so a contractor will check both before replacing the thermocouple.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. The heat exchanger, the igniter, the flow sensor and the venting can all be serviced or replaced without swapping out the whole unit. Mineral buildup inside the heat exchanger is a common issue, especially since it restricts flow and trips the unit's safety controls. A contractor can flush or descale the unit and replace whichever part has failed.
