What Blount County winters do to your water heater
Cold groundwater takes more work to heat, and from October through April your water heater is doing that work every day. On nights that average 31°F, it runs longer and more often just to hold the temperature you set. That extra cycling wears on the heating element and thermostat, and it is often why a water heater that was fine in summer starts running out of hot water faster once winter sets in.
Power matters too. Tennessee has logged 20 winter storms and 107 damaging wind events here over the past ten years, and a share of households go a full day or more without power when storms hit. An electric water heater should restart on its own once power returns, but a gas unit with an electronic igniter may not relight until someone resets it. If your water heater has gone cold after an outage, that is usually why.

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 failed. Water heater tanks corrode from the inside over years, and once the steel gives way, no seal or fitting will stop the leak. It can also be a loose drain valve or a fitting that's just dripping down the side and pooling at the bottom, which a contractor can check before assuming the tank is done. If the tank itself is rusted through, the water heater needs to be replaced, not repaired.
- 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 shuts the gas off even though the flame is lit. A dirty pilot orifice or a draft in the area can also blow the flame out. A contractor can test the thermocouple and clean or replace it, which usually solves the problem.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Ignition failures, error codes, and mineral buildup in the heat exchanger are the most common issues, and a contractor can flush the unit or replace the part causing the fault. Tankless units also have more electronics than a tank model, so a technician who works on them regularly will diagnose the code correctly rather than guessing.
