What Forsyth County winters do to a water heater
Your water heater works hardest from October through April, when incoming water runs cold and the tank has to make up more ground to hit temperature. Winter nights here average 33°F, so the burner or the elements are cycling on more, and more often, to keep up. That extra cycling wears on the thermostat and the heating element in an electric unit, or the burner assembly and thermocouple in a gas one.
Georgia saw 31% of households lose power for 24 hours or more in 2024, and Forsyth County has logged 5 winter storms and 48 damaging wind events over the past ten years. When the power drops and comes back, an electric water heater should return to work on its own. A gas unit with a standing pilot stays lit through the outage. If yours does not come back on, or the water is not hot when it should be, that is worth a look.

A new water heater would cut about $100 a year off hot water for a typical Georgia 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 tank has likely rusted through from the inside and started to leak, which means the tank itself needs to be replaced, not patched. It could also be the drain valve or a fitting that has loosened, both of which a contractor can check before condemning the tank. If the leak is coming from the top or from a fitting, that part can sometimes be repaired. Once water is coming from the tank itself, the unit is done and needs replacing.
- 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 can't confirm the flame is lit, so the gas valve shuts off the pilot supply. A dirty pilot orifice or a draft blowing out the flame can cause the same thing. A contractor can test the thermocouple and clean or replace the part that's failing.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Common issues include a scaled-up heat exchanger, a failed igniter, or an error code pointing to a sensor or flow issue. A contractor can flush the unit, replace the failed part, or reset the system depending on what's wrong. Full replacement is usually only needed when the heat exchanger itself has failed.
