Cold water and cold power don't mix well
Winter nights in Mountain Home average 28°F from December through February, and your water heater works harder those nights to keep up. The tank pulls in cold groundwater, and the burner or heating element has to run longer to bring it up to temperature. That extra runtime wears on the thermostat and the heating element in an electric unit, or the burner assembly in a gas one.
Baxter County has seen 13 winter storms and 51 damaging wind events over the past ten years, and storms like these knock out power. Across Arkansas, close to a quarter of households lost power for a full day or more in 2024. Most water heaters come back on by themselves once power returns, but if yours doesn't, or the water isn't hot again after an outage, something else has likely failed.

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?
- The tank itself has likely rusted through and is starting to fail. Water heaters have a steel tank with a glass lining inside, and once that lining cracks, the steel underneath corrodes and eventually lets water seep out through the bottom. It could also be a loose drain valve or a fitting at the bottom of the tank, which a contractor can check before assuming the tank is done for. A leaking tank will not repair, it needs to be replaced.
- Why won't the pilot light on my water heater stay lit?
- Most of the time this means the thermocouple has worn out. That's the small sensor that sits in the pilot flame and tells the gas valve it is safe to keep sending gas. When it fails, the valve shuts the gas off as a safety measure even though the flame is lit. A dirty pilot orifice or a draft blowing out the flame can cause the same thing, and a contractor can tell which one it is.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Mineral buildup on the heat exchanger, a failed igniter, or a clogged inlet filter are common issues, and none of them mean the unit needs to be replaced. A contractor can flush the system or replace the specific part that failed.
