Hamilton County water heaters work through a lot of cold mornings
From December through February, nights here average 32°F. Water coming into the tank is cold too, so the unit runs longer to bring it up to temperature. That extra runtime wears on the heating element in an electric water heater and on the burner assembly in a gas one.
Hamilton County has also seen 117 damaging wind events and 31 winter storms over the past ten years, and in Tennessee, 20% of households went at least 24 hours without power in 2024. A power cut shuts down an electric water heater until service returns. Most units come back on by themselves once the power does, but if yours does not, the thermostat or heating element may be the reason.

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 of the time this means the tank itself has rusted through, and a rusted tank cannot be patched or sealed. It also might not be the tank at all. A failed drain valve, a loose fitting, or a pressure relief valve letting go can all look like a leak from the bottom. Shut off the water and power to the tank and have a contractor look at it before you replace anything.
- 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 flame and keeps gas flowing to it. When it wears out, it shuts the gas off even though the pilot is lit. A dirty pilot orifice or a draft near the pilot can cause the same thing. This is a gas part, so have it checked rather than relighting it over and over.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Mineral buildup on the heat exchanger, a failed igniter, or a clogged inlet filter are common issues a contractor can fix without replacing the unit. A contractor can open the unit up, find which part failed, and tell you whether it is worth repairing or has reached the end of its life.
