Cincinnati water heaters work hardest right when you need them most
Cold water comes into your tank colder from October through April, and on nights near 25°F the burner or heating element has to run longer to catch up. That extra run time wears on the parts that do the work, the thermostat, the heating element, the gas valve. You notice it as water that used to be hot turning lukewarm, or a tank that takes longer to recover between showers.
Hamilton County also loses power sometimes. Statewide, 18% of households went at least a day without it in 2024, and the area has seen 169 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps working through an outage. One with electronic ignition or an electric tank won't heat water until the power is back, and needs to be checked once it is.

A new water heater would cut about $70 a year off hot water for a typical Ohio 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 often the tank itself has rusted through from the inside and is starting to fail. Water heaters corrode from within over years, and once the tank wall is breached, no amount of tightening fittings will stop it. It can also be the drain valve at the bottom, a loose fitting there, or condensation from a new gas unit still warming up, and those are worth checking first since they can be fixed rather than replaced. If the water is coming from underneath the tank itself, the tank is done and needs to be replaced, not repaired.
- 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 or sits out of position, 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. A contractor can test the thermocouple in a few minutes and replace it if it is reading weak.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Mineral scale buildup on the heat exchanger is the most common issue, especially without regular flushing, and it can be cleaned out. Failed igniters, sensors, and fan motors are also standard repairs. It is usually only the heat exchanger itself, if it has cracked or corroded through, that means the unit needs to be replaced instead.
