Cold groundwater and long winters wear on your water heater here
Your water heater works harder from October through May, eight months of the year, heating water that starts out cold. On winter nights that average 22°F, the incoming water is at its coldest. The burner or heating element has to run longer to bring it up to temperature. That extra runtime wears on the heating element, the thermostat and the burner assembly a little more each time.
Lucas County has seen 8 winter storms and 91 damaging wind events over the past ten years, and storms like these knock out power. Statewide, 18 percent of Ohio households lost power for at least 24 hours in 2024. A gas water heater with a standing pilot keeps heating through an outage. One with an electric ignition needs power to relight, and an electric water heater stops heating until the power comes back. Either way, you may notice the water running lukewarm or cold after a storm, even once the lights are back on.

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 tank needs to be replaced, not repaired. Sediment builds up in the bottom of the tank over years, and it corrodes the steel from the inside until a leak starts. A leak can also come from a loose drain valve or a fitting, and those are worth checking before you assume the worst. If the tank is the source, water will keep collecting underneath it no matter how tight you turn anything.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small part that senses the pilot flame and tells the gas valve to stay open. When it wears out, it can't confirm the flame is lit, so the gas valve shuts off and the pilot goes out. A dirty pilot tube or a draft can also blow the flame out on its own. A licensed contractor can test the thermocouple and replace it if it's reading weak.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Common issues are a fouled heat exchanger from mineral buildup, a failed igniter, or an error code from a sensor, and each of those can be fixed without replacing the unit. Tankless units also tend to run for years past the point a tank-style heater would need replacing, so repair is usually the first step. A contractor can pull the error code and tell you exactly what part is at fault.
