Power outages here leave you without hot water
Ohio households went at least 24 hours without power at a rate of 18% in 2024, and Butler County has seen 13 winter storms and 94 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage since the pilot needs no power at all. One with electronic ignition, or an electric unit, stops heating until the power comes back, and most start up again on their own once it does.
Winter nights here average 24°F, and homes need heat from October through April. With the house cold that long, whatever hot water is left in the tank runs out fast once the power is gone, and nothing replaces it until the unit can fire again.

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 of the time this means the tank itself has rusted through, and that means it needs to be replaced, not repaired. Water heaters fail from the inside out as sediment builds up and eats through the lining, so by the time you see water on the floor the damage is already done. It could also be a loose drain valve or a fitting on the bottom of the tank, which is a much smaller fix. A contractor can tell you which one you're dealing with by looking at where the water is coming from.
- Why won't the pilot light on my water heater stay lit?
- The most common reason is a thermocouple that has worn out and no longer senses the pilot flame, so the gas valve shuts it off as a safety measure. A dirty or misaligned pilot orifice can cause the same problem. Wind or a draft in the area can also blow the flame out on some units. A contractor can test the thermocouple in a few minutes and replace it if that's the cause.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable, including a failed igniter, a clogged inlet filter, or buildup on the heat exchanger from hard water. Error codes on the display usually point straight to the part that needs attention. If the heat exchanger itself has cracked or corroded through, that's a replacement rather than a repair. A contractor can read the code and check the unit to tell you which one you're facing.
