Cold nights and outages both put your water heater to work
Chapel Hill sees winter nights average 31°F from December through February, and your water heater runs harder those months to bring water up to temperature. That extra work falls on the heating element or the burner, and on the thermostat that tells it when to fire.
Power matters too. Orange County has had 121 damaging wind events and 8 winter storms over the past ten years, and statewide, a quarter of households lost power for at least 24 hours in 2024. Electric water heaters go cold the moment power drops, and gas units with electronic ignition won't relight on their own once it's back. If your water heater didn't turn back on after an outage, that's usually why.

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 failed. Sediment builds up inside over the years, and it wears through the steel from the inside until water starts seeping out at the seam or the base. A leak at the bottom almost always means the tank needs to be replaced, not repaired, since there's no way to patch a tank that's rusted through. Before you assume the worst, check the fittings and the drain valve at the bottom too, since a loose connection there can look like a tank leak but is a much simpler 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 stay open. When it wears out, it fails to sense the flame correctly and shuts the gas off even though the pilot is lit. A dirty or misaligned pilot orifice can cause the same problem by keeping the flame from reaching the thermocouple properly. Either way, a standing pilot doesn't rely on your home's power, so if it keeps going out, the issue is with the gas side of the system, not an outage.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Common issues are a scaled-up heat exchanger, a failed igniter, or a flow sensor that's stopped reading correctly, and a contractor can replace or clean any of these without swapping the whole unit. Tankless units also run diagnostic codes on a display or through a series of blinks, which point straight to the part causing trouble. Regular descaling helps prevent a lot of these repairs from coming up in the first place, especially in areas with harder water.
