Cold groundwater and lost power both take a toll here
Water heaters in Fairmont work against cold incoming water from October through May, with winter nights averaging 24°F. The colder that water is, the longer the burner or the heating element has to run to bring a tank up to temperature, and that extra run time wears on the thermostat and the heating element in an electric unit, or the igniter and burner assembly in a gas one.
Marion County has also seen 57 damaging wind events and 5 winter storms over the past ten years, and statewide, over a third of households lost power for 24 hours or more in 2024. A gas water heater with a standing pilot will keep working through an outage, but most electric units and any gas unit with electronic ignition will not come back on until a homeowner relights it or resets it. After a long outage, check whether your water heater needs to be restarted before you assume it has failed.

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 failing, and that means replacement, not repair. Water pools at the base because sediment settles at the bottom of the tank over the years and eats through the steel from the inside. It can also be a loose drain valve or a fitting that has worked itself loose, which a contractor can check in a few minutes. If the leak is actually dripping from above, from the temperature and pressure relief valve or a fitting higher up, it only looks like a bottom leak once it runs down the side.
- Why won't the pilot light on my water heater stay lit?
- The thermocouple is the usual reason. It is the small sensor that sits in the pilot flame and tells the gas valve the flame is lit. Once it wears out or sits out of position, the valve shuts the gas off within seconds of you letting go, even though the pilot lit fine. A dirty pilot orifice or a draft pulling the flame around can do the same thing, so a contractor will check both before replacing anything. Because winter nights here drop to 24°F on average, a water heater that will not hold a pilot is worth getting looked at quickly rather than waiting.
- Can a tankless water heater be repaired?
- Yes, most tankless problems are repairs, not replacements. A flow sensor, an igniter, or a heat exchanger that has scaled up from hard water are the usual culprits, and each of those can be serviced or swapped on its own. Error codes on the unit's display point a contractor straight to which part is failing. Replacement mainly comes up when the heat exchanger itself has cracked, since that is the core part of the unit.
