What Cabarrus County winters do to a water heater
Your water heater works harder from October through April, with winter nights averaging 32°F. Cold ground water comes into the tank colder, so the heating element or burner runs longer to bring it up to temperature. That extra runtime wears on the thermostat and the heating element in an electric tank, or the burner assembly in a gas one.
Power matters too. A quarter of North Carolina households went at least a day without power in 2024, and this county has seen 60 damaging wind events over the past ten years. When the power drops, an electric water heater stops heating until it's back, and most units simply start again on their own. If yours doesn't, or if you're noticing lukewarm water, a slow recovery, or a tank that won't fire back up, that's worth a look.

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?
- Most of the time this means the tank itself has rusted through from the inside and is failing. Water heaters aren't built to be patched once the tank goes, so this usually means replacement rather than repair. It could also be a loose drain valve or a fitting at the bottom, which a contractor can check before assuming the worst. If the leak is coming from the tank and not a fitting, shut off the water supply to the unit so it doesn't keep draining.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small part that senses the flame and tells the gas valve to stay open. When it wears out, the flame lights but the valve shuts the gas off seconds later. A dirty pilot orifice or a draft blowing out the flame can cause the same thing. A contractor can test the thermocouple and replace it if that's the problem, since it isn't something to keep relighting on your own.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater can be repaired without replacing the whole unit. Common repairs include descaling the heat exchanger, replacing an igniter, or fixing a sensor that's throwing an error code. Tankless units usually display an error code when something's wrong, and that code tells a contractor what part needs attention. Replacement is usually only needed when the heat exchanger itself has failed.
