What Anderson County does to a water heater
Anderson County gets cold enough, five months a year, that your water heater works harder just to keep up, and winter nights averaging 34°F mean the tank is drawing in cold water and holding heat against the cold longer than it does the rest of the year. That extra cycling wears on the heating element and the thermostat that controls it.
Power is the other problem here. Nearly half of South Carolina households were without power for at least 24 hours at some point in 2024, and the county has seen 111 damaging wind events over the past decade. A gas water heater with a standing pilot will keep working through an outage. One with electric ignition or an electric tank will not, and when the power comes back, most units restart on their own. If yours does not, that points to a problem with the unit itself, not the outage.

A new water heater would cut about $300 a year off hot water for a typical South 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 cause is the tank itself failing from the inside out. Sediment builds up on the bottom of the tank over years, and it can corrode a hole through the steel or cause enough heat stress to crack a weld seam. Once that happens the tank cannot be patched or sealed, and it needs to be replaced. Water at the bottom can also come from the drain valve or a loose fitting, so a contractor will check those first before condemning the tank.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and no longer tells the gas valve that the pilot is burning, so the valve shuts off the gas as a safety measure. A weak or dirty pilot flame can cause the same problem, and so can a draft that keeps blowing the flame out. A contractor can test the thermocouple and clean or adjust the pilot assembly to fix it. A standing pilot does not run on electricity, so power outages will not affect it, but if the flame keeps going out on its own the part likely needs replacing.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. A contractor can clean mineral buildup from the heat exchanger, replace an igniter or flow sensor, or clear a blocked vent. How much sediment builds up over time depends on the water hardness in the area, which affects how often the unit needs service. If the heat exchanger itself has cracked, that is one of the few failures that usually means replacing the unit instead.
