Cold nights and shaky power add up to water heater trouble in Gaffney
Winter nights here average 32°F from December through February, and your water heater works harder every one of those nights to bring cold groundwater up to temperature. That extra work falls on the heating element or burner, and over years of cold winters it's often the first part to fail. You will notice hot water running out faster than it used to, or not getting hot at all.
Cherokee County has seen 6 winter storms and 49 damaging wind events over the past ten years, and storms here knock out power. Statewide, 45% of households lost power for at least 24 hours in 2024. A gas water heater with a standing pilot will keep working through an outage, but an electric one stops heating until the power comes back, and a tank left cold for a day takes time to recover once it does.

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 of the time this means the tank itself has rusted through and is starting to fail. Water heaters don't get repaired for this, they get replaced, since once the steel tank is breached there's no patch that holds. Before you assume the worst, check that the leak isn't actually coming from a loose drain valve or a fitting on top that's dripping down the side. If it's true tank leakage, water pooling under the unit, a contractor can confirm it and get a new one in.
- Why won't the pilot light on my water heater stay lit?
- The most common reason is a weak or dirty thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out or gets coated in soot, the valve shuts the gas off as a safety measure even though the flame was fine. A clogged pilot orifice or a draft blowing out the flame can cause the same problem. This is a repair a contractor can usually make without replacing the whole unit.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Mineral buildup on the heat exchanger, a failed igniter, or a blocked vent are common causes and none of them mean the unit is done. Regular descaling helps prevent the buildup from happening again. A contractor can diagnose which part is causing the fault code and repair or replace just that part.
