What winter and storms do to water heaters in Madison County
Your water heater works harder from November through March, when winter nights average 37°F and the incoming water is colder than the rest of the year. The unit has to work longer to bring water up to temperature, and that extra runtime wears on the heating element in an electric tank and the burner assembly in a gas one.
Storms add another risk. Madison County has seen 160 damaging wind events and 4 winter storms over the past ten years, and across Mississippi, 30 percent of households lost power for 24 hours or more in 2024. When the power drops and comes back, most electric water heaters restart on their own, but a gas unit with an electronic ignition may need to be relit by hand. If your water heater does not come back on after an outage, that is usually why.

A new water heater would cut about $80 a year off hot water for a typical Mississippi 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 the tank itself has rusted through from the inside and is starting to fail. Sediment builds up on the bottom of the tank over years, and it traps moisture against the steel until it eats a hole through. A loose drain valve or a fitting on the cold water line can also leak and pool at the bottom, which looks the same but costs far less to fix. A contractor can tell the difference by drying everything off and watching where the water actually comes from.
- 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 or sits out of position, it shuts the gas off even though the flame is lit. A dirty pilot tube or a draft blowing across the flame can cause the same thing. Either way it takes a contractor to check the part and replace it, since the gas valve itself is not something to take apart.
- Can a tankless water heater be repaired?
- Yes, most tankless problems are repairable without replacing the unit. Mineral buildup on the heat exchanger is the most common issue, especially if the unit has never been flushed, and it can cause hot water to run lukewarm or shut off under load. Igniter and flow sensor failures are also common and both can be replaced. A contractor can run the unit's error code, which most models display, to point straight at the failed part.
