Athens water heaters run into more storms than winters
Winters here are short. Athens only calls for heat from November through March, and even then the nights average 35°F. Your water heater does not get much of a break from cold-weather strain the way furnaces in colder places do.
What it does deal with is the grid. Clarke County has seen 48 damaging wind events over the past ten years, and across Georgia almost a third of households lost power for a full day or more in 2024. A gas water heater with a standing pilot rides that out fine. One with electronic ignition or an electric unit will sit cold until the power comes back, and if it does not reset on its own, you will notice when the water runs cold.

A new water heater would cut about $330 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 most common reason is that the tank itself has corroded through and is failing. Sediment builds up at the bottom of the tank over years, and it wears at the steel and the glass lining until a crack or pinhole opens up. A leak can also come from the drain valve or a fitting instead of the tank, and those can sometimes be tightened or replaced. Once the tank itself is leaking, it needs to be replaced, not patched, so it's worth having a contractor check where the water is actually coming from before you assume the worst.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and can no longer sense the flame, so the gas valve shuts back off. A thermocouple sits in the pilot flame and tells the gas valve to stay open. After years of heating and cooling, it weakens and starts cutting the gas even when the pilot is lit. A dirty pilot orifice or a draft blowing out the flame can also cause this, but a worn thermocouple is the usual culprit and a contractor can replace it directly.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater can be fixed without replacing the whole unit. The igniter, the flow sensor, and the heat exchanger can all be serviced or swapped out on their own. Mineral buildup is common in these units and often causes error codes or reduced hot water, and flushing the system clears it in many cases. A contractor can pull the error code from the unit's display and tell you what part is actually failing.
