What Raleigh winters do to your water heater
Your water heater works harder from October through April, when incoming water runs colder and the tank has to make up more ground before it reaches your tap. On nights that average 32°F, that gap is at its widest, and the heating element or gas burner runs longer each time to close it. That extra runtime wears on the parts that do the heating.
Power loss is also a real risk here. In 2024, a quarter of North Carolina households went at least 24 hours without power, and Wake County has logged 308 damaging wind events and 7 winter storms over the past ten years. An electric water heater does nothing until power is back. A gas unit with a standing pilot keeps working through the outage, but one with an electronic ignition will not light until it has power again, so you notice cold water right when you need hot.

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 often it means the tank itself has rusted through and is failing, not something that can be sealed or patched. Water expands as it heats, and years of that cycling wear on the tank until a crack or pinhole opens at the bottom seam. It can also be the drain valve or a fitting that has loosened, which a contractor can check before assuming the tank is done. Either way, a leaking tank needs attention fast, since a failed tank can dump many gallons onto the floor around it.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out it can't confirm the flame, so the valve shuts the gas off as a safety measure. A dirty pilot tube or a draft pulling the flame sideways can cause the same thing. A standing pilot doesn't use electricity, so a power outage isn't the cause here, but a contractor can tell which part is failing.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. Mineral buildup on the heat exchanger, a failed igniter, or a blocked vent are common issues, and each is a part or a cleaning a contractor can address without replacing the whole unit. If the heat exchanger itself has cracked, that's the one failure that usually means replacement instead of repair.
