Cullman County winters are hard on a water heater's power supply
Water heaters here work through cold nights averaging 33°F from December through February, and the tank has to work harder to keep up. That extra demand falls on the heating element or the gas control valve, depending on what you have.
Almost one in five Alabama households lost power for a day or more in 2024, and Cullman County has logged 174 damaging wind events and 5 winter storms over the past ten years. When the power goes out and comes back, most electric water heaters restart on their own. Gas units with a standing pilot never needed power to begin with. But if yours has an electronic ignition and doesn't relight after an outage, that's the igniter or control board, not the tank itself.

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 from the inside and is starting to fail. Water heaters corrode from the inside over years, and once the tank wall gives way, the leak will not stop or seal itself. It could also be the drain valve or a fitting at the bottom, which a contractor can check before condemning the tank. If the leak is coming from the tank body, the unit needs to be replaced, not repaired.
- 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 fails to sense the flame and shuts the gas off even though the pilot is lit. A dirty pilot orifice or a draft blowing the flame out can cause the same problem. A contractor can test the thermocouple and replace it if it is reading weak.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Issues like a clogged inlet filter, a buildup of scale on the heat exchanger, or a failed igniter can be cleaned or replaced without swapping out the whole unit. Error codes on the display usually point a contractor straight to the part at fault. Whether repair makes sense depends on the age of the unit and what's actually failed, which a contractor can check in person.
