Greene County winters put your water heater to work
Groundwater runs cold from October through April, and that means your water heater is working seven months out of the year to hit the same temperature at the tap. Longer burner runs and longer element runs wear on the thermocouple or the element itself, and that part tends to fail years before it should.
Power is the other piece. Twenty percent of Tennessee households went at least a day without power in 2024, and Greene County has logged 25 winter storms and 99 damaging wind events over the past ten years. A gas water heater with a standing pilot stays lit through an outage. One with an electronic ignition needs the power back before it will light again. Either way, a storm in the middle of winter is a bad time to find out the tank was already struggling.

A new water heater would cut about $280 a year off hot water for a typical Tennessee 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?
- Most often the tank itself has rusted through and is failing from the inside. Sediment builds up at the bottom of the tank over years, and once it works through the steel, water finds a way out and won't stop. A loose drain valve or a fitting can also leak from that area, and those are worth checking first since they can be tightened or replaced. If the tank itself is the source, it needs to be replaced rather than 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 space can also blow the flame out. A contractor can test the thermocouple and replace it if that's the issue, which is a quick fix compared to problems with the gas valve itself.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. The heat exchanger can scale up from mineral deposits, the igniter can fail, or the flow sensor can stop reading correctly, and each of those parts can be serviced or replaced on its own. A contractor can flush the unit or replace the specific part causing the trouble rather than the whole system.
