What winter does to a water heater here
Groundwater coming into your house is cold all winter, and from December through February your water heater is working against nights that average 25°F. The unit runs longer to make up that difference, and the burner or heating element cycles more to hold temperature. That extra cycling is what wears out a thermocouple or an element years before it should quit.
Jefferson County has seen 14 winter storms and 92 damaging wind events over the last ten years, and statewide, more than a third of households lost power for at least a day in 2024. A gas water heater with a standing pilot will keep working through an outage. One that depends on electronic ignition or a powered element won't, and you'll notice hot water running out or not showing up at all until power is back.

A new water heater would cut about $370 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 holding water inside. Sediment builds up on the bottom of the tank over years, and it traps moisture against the steel until it corrodes a hole. Once a tank is leaking this way, it needs to be replaced, not patched. Water pooling underneath can also come from a loose drain valve or a fitting on top that is running down the side, so a contractor should check those before condemning the tank.
- Why won't the pilot light on my water heater stay lit?
- The thermocouple is usually the reason a pilot light won't stay lit. This is the small sensor that sits in the pilot flame and tells the gas valve it is safe to keep gas flowing. Once it wears out or gets coated in soot, it cools too fast when you let go of the knob and the valve shuts the gas off. A dirty pilot orifice or a draft blowing the flame around can cause the same thing, so a contractor will check the thermocouple first and go from there.
- 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 are the parts that fail most often, and each can be tested and replaced on its own. Mineral buildup on the heat exchanger is common and is cleared with a descaling flush rather than a replacement. A contractor can pull the error code the unit is showing and tell you which part is at fault.
