Cold groundwater, more hours on the burner
Your water heater works harder from October through April, seven months a year, because the water coming into the tank is colder to start with. On nights that average 25°F, the burner or the element has to run longer just to hold the tank at temperature. That extra run time wears on the thermostat and the heating element in an electric tank, or the burner assembly and thermocouple in a gas one.
Power is part of it too. In Ohio, 18% of households went at least 24 hours without power at some point in 2024. A gas water heater with a standing pilot will keep making hot water through an outage like that. One with electric ignition will not light again until the power is back, and you will notice cold water until it does.

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 once that happens the water heater needs to be replaced, not repaired. Before you assume the worst, check that the leak isn't actually coming from a loose drain valve or a fitting above the tank, since those can be fixed on their own. Water pooling underneath can also be condensation on a newer gas unit, so it's worth drying the area and watching where the water shows up again.
- 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 stops sending that signal and the valve shuts the gas off, so the flame goes out. A dirty pilot orifice or a draft in the area can cause the same thing, so a contractor will check both before replacing any part.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Mineral buildup on the heat exchanger is the most common issue, and it's cleared with a descaling flush rather than a replacement. Igniters, sensors, and fans can also fail on their own and be swapped out individually, so a full unit replacement is rarely the first step.
