Mentor winters put your water heater to work
Cold groundwater runs into your water heater from October through May, eight months of the year. On nights that drop to 23°F, the burner or the heating element has to run longer to bring that water up to temperature. That extra run time wears on the thermostat and heating element in electric units, and on the burner assembly in gas units.
Power loss adds to the strain. In Ohio, 18% of households went at least 24 hours without power in 2024. Most water heaters restart on their own once power returns, but a day without it means a day without hot water while the tank catches back up.

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 most common cause is the tank itself failing from the inside out, where years of sediment and rust eat through the metal. Once a tank is rusted through, it cannot be patched or sealed, it needs to be replaced. Leaks can also come from a loose drain valve or a fitting on top that drips down the side and pools at the bottom, so it's worth checking those before assuming the tank is done. A contractor can tell you which one you're dealing with.
- Why won't the pilot light on my water heater stay lit?
- Most of the time this means the thermocouple has worn out and can no longer sense that the flame is lit, so it shuts the gas off as a safety measure. A weak pilot flame, a draft near the burner, or a clogged pilot tube can cause the same thing. This is a gas part, so it should be diagnosed and replaced by a contractor rather than something to keep relighting on your own.
- 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 faulty sensor are common issues, and each has its own fix. A contractor can flush the unit or replace the failed part depending on what's wrong.
