What winter and storms do to your water heater in Clayton
Winter nights here average 33°F from December through February, and cold water coming into the tank means the heating element or burner has to work harder to get it to temperature. That extra work adds up over the season, and it's often when a homeowner first notices weaker hot water or a tank that takes longer to recover between showers.
Johnston County has seen 7 winter storms and 164 damaging wind events over the past ten years, and storms like these knock out power. A quarter of North Carolina 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 one with an electronic ignition or a fully electric unit will not come back on until the power does, and sometimes not without a reset.

A new water heater would cut about $300 a year off hot water for a typical North Carolina 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?
- The tank itself has likely rusted through and is leaking, which means it needs to be replaced, not repaired. Water heaters have a steel tank with a glass lining inside, and once that lining cracks, the steel underneath rusts and eventually gives way. A leak can also come from a loose drain valve or a fitting near the bottom, and those can sometimes be tightened or replaced. A contractor can tell you which one you're dealing with, but if the tank itself is rusted through, a new water heater is the only fix.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that sits in the pilot flame and tells the gas valve it's safe to keep the gas flowing. When it wears out, it can't hold that signal, so the gas valve shuts off and the flame dies. A dirty pilot orifice or a draft near the burner can cause the same thing. A thermocouple is inexpensive and straightforward for a contractor to replace, so that's usually where the fix starts.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems can be repaired rather than requiring a full replacement. Common issues include a buildup of mineral scale on the heat exchanger, an igniter that fails to spark, or an error code pointing to a sensor problem. Because a tankless unit has no tank to rust out, repairs tend to focus on these parts rather than the whole unit failing. A contractor can pull the error code and tell you exactly what's involved for your unit.
