What winter and storms do to your water heater in Greenwood
Your water heater works harder from November through March, when incoming water runs cold and winter nights average 35°F. The burner or heating element has to run longer to get the same hot shower, and that extra runtime wears on the thermostat and the heating element itself. You notice it as water that takes longer to heat up, or a tank that runs out faster than it used to.
Greenwood County has seen 53 damaging wind events and 2 winter storms over the past ten years, and power interruptions come with that. Statewide, 45% of households lost power for 24 hours or more in 2024. Most gas water heaters with a standing pilot keep running through an outage, but electric water heaters and gas units with an electronic ignition go cold and need to reset once power comes back.

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 at the bottom of the unit. Once a tank starts leaking this way, it cannot be patched or sealed, because the corrosion is happening from the inside out. Sometimes what looks like a tank leak is actually the drain valve or a loose fitting, and that part can be replaced. A contractor can tell the difference by drying the area and watching where the water shows up again.
- Why won't the pilot light on my water heater stay lit?
- This is usually the thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out or sits out of position, the valve shuts off gas to the pilot as a safety measure, even though the flame is fine. A dirty pilot orifice or a draft in the area can cause the same problem. A contractor can test the thermocouple's output and replace it if it is reading low.
- Can a tankless water heater be repaired?
- Yes, most tankless problems are a specific part failing, not the whole unit going bad. The heat exchanger, the flow sensor, and the igniter are the parts that most often need attention, and each can be replaced on its own. Mineral buildup from hard water is a common cause of trouble too, and flushing the unit clears it. A contractor can run the unit's error code to find out which part is failing before recommending a repair.
