Your water heater works through a long, cold winter
Loudon County gets seven months of heating season, October through April, and winter nights average 32°F from December through February. Cold groundwater comes into the tank at a lower temperature during those months, so the burner or the heating element runs longer and more often to keep up. That extra run time wears on the thermostat and the heating element in an electric unit, or the burner assembly in a gas one.
Power matters too. Twenty percent of Tennessee households went at least 24 hours without power at some point in 2024, and the county has seen 10 winter storms and 60 damaging wind events over the past ten years. When the power drops and comes back, most water heaters restart on their own. But a storm that knocks out power for a day can leave you with a tank full of cold water right when you need it most.

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 of the time this means the tank itself has rusted through and is failing from the inside. Sediment builds up at the bottom of the tank over the years, and once it wears through the steel, the leak won't stop or seal itself. It can also be a loose drain valve or a fitting that's simply worked itself loose, which a contractor can check before assuming the tank is done. Once the tank is actually cracked, though, the water heater needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and can no longer sense that the flame is lit, so it shuts the gas off as a safety measure. It can also mean a draft is blowing the flame out, or the pilot tube itself is clogged and starving the flame of gas. A standing pilot doesn't use any electricity, so a power outage isn't the cause. A contractor can test the thermocouple and replace it if that's the problem, which is a common and straightforward fix.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Issues like a clogged inlet filter, a failed igniter, mineral buildup on the heat exchanger, or an error code from a sensor can usually be fixed without replacing the unit. A contractor can pull the fault code and pinpoint what's actually failing. It's rare for the whole unit to need replacing unless the heat exchanger itself has failed.
