What winter here does to a water heater
Randolph County homes need heat from October through April, seven months a year. Your water heater works harder in that stretch, pulling in colder groundwater and running longer to bring it up to temperature. Winter nights average 32°F from December through February, and that cold reaches the pipes and tank even in a garage or basement.
The county has seen 202 damaging wind events and 7 winter storms over the last ten years, and a quarter of North Carolina households lost power for at least 24 hours in 2024. When the power drops, a gas water heater with a standing pilot keeps working, but most electric units and gas units with electronic ignition go cold until the power comes back and they reset. If your water is taking longer to heat, or not heating at all after an outage, that is where to start looking.

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 most common reason is that the tank itself has rusted through from the inside and is failing. Sediment builds up at the bottom of the tank over years, and once it wears through the lining, water finds a way out and the tank can't be patched. A leak can also come from a drain valve that isn't sealing or fittings that have loosened, which a contractor can check before assuming the tank is done. If the water is actually coming from the tank wall, the water heater needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- Most often this means the thermocouple has worn out and can no longer sense that the pilot is lit, so the gas valve shuts it off. A draft blowing across the pilot can also blow it out, and a dirty pilot orifice can keep it from burning steady. A contractor can test the thermocouple and replace it, which usually solves the problem. If the pilot lights but won't hold once you release the knob, that points straight to the thermocouple.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Mineral buildup on the heat exchanger is common and is cleared with a descaling flush. Igniters, flow sensors, and venting issues can also be diagnosed and fixed without replacing the unit. A contractor can tell you after inspecting it whether repair makes sense or the unit has reached the end of its service life.
