Cold groundwater and winter power outages both work against your water heater
Water heaters in Anderson work harder from October through May, when the water coming into the tank is colder and the burner or elements have to run longer to bring it up to temperature. That extra runtime adds up over eight months, and it's usually the heating element or the burner assembly that wears out first.
Winter storms add a second problem. Madison County has seen 13 winter storms and 68 damaging wind events over the past ten years, and statewide, 17% of households lost power for 24 hours or more in 2024. Electric water heaters go cold the moment the power drops. Gas units with a standing pilot keep working, but many newer ones use an electronic ignition that needs power to light, so a storm outage can leave you with no hot water until the power comes back and the unit resets.

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 the tank itself has rusted through, and once that happens the tank needs to be replaced, not patched. It can also be a loose drain valve or a fitting that's simply worked itself loose over the years, which a contractor can tighten or replace. Water pooling underneath can also come from the temperature and pressure relief valve venting down the overflow pipe, so it's worth checking where the water is actually coming from before assuming the worst. If the tank is rusted, turn off the water supply and the power or gas to the unit until someone can look at it.
- Why won't the pilot light on my water heater stay lit?
- The thermocouple is the most common reason a pilot won't stay lit. It's a small sensor that tells the gas valve the pilot is burning, and once it wears out or sits slightly out of position, the valve shuts the gas off as a safety measure. A dirty pilot orifice or a draft in the area can cause the same problem. Either way this is a gas appliance issue, so it's worth having a contractor check it rather than repeatedly relighting it yourself.
- 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 sensor can usually be fixed without replacing the unit. Error codes on the display are there to point to the specific problem, so a contractor can usually diagnose what's wrong before opening anything up. Whether it makes more sense to repair or replace depends on the age of the unit and what's actually failed, which is something a contractor can weigh in on for your specific one.
