Elizabethton winters put a real load on your water heater
Winter nights here average 27°F from December through February, and cold groundwater coming into the tank means the burner or the heating element has to run longer to bring the water up to temperature. That extra runtime wears on the thermostat and heating element in an electric unit, or the burner assembly in a gas one, and it shows up as water that never quite gets hot or takes longer to.
Carter County has also seen 33 winter storms and 24 damaging wind events over the past ten years, and outages come with weather like that. An electric water heater needs the power back on to heat again, while a gas unit with a standing pilot keeps working through the outage itself. If your water runs cold after an outage and stays that way, the unit may need a reset or a look at the thermostat.

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 it means the tank itself has rusted through and is failing. Water heaters corrode from the inside over years, and once the tank wall gives way, no part or seal will stop the leak. It could also be a loose drain valve or a fitting on the bottom, which a contractor can check before assuming the tank is done. If the leak is coming from the tank itself, the water heater needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- The most common reason is a worn thermocouple, the small part that senses the pilot flame and keeps gas flowing to it. When it wears out, it shuts the gas off even though the pilot is lit, so the flame dies once you let go of the button. A dirty pilot orifice or a draft in the area can also blow the flame out. A contractor can test the thermocouple in a few minutes and replace it if that is the cause.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Common issues are a buildup of mineral scale on the heat exchanger, a faulty igniter, or an error code from a sensor, and all of these are things a contractor can diagnose and fix without replacing the unit. Tankless units also need the heat exchanger flushed periodically to keep scale from building up, especially with hard water. If the heat exchanger itself has cracked or failed, that is the one case where replacement is usually the better option.
