Cold groundwater keeps your water heater working most of the year
Water heaters in Troy run October through May, eight months of the year, to make up for cold water coming into the house. On nights that average 23°F, the tank has to work harder to bring that water up to temperature. That extra work falls on the heating element or burner and on the thermostat that controls it.
Miami County has seen 8 winter storms and 69 damaging wind events over the past ten years, and statewide, 18% of Ohio households lost power for 24 hours or more in 2024. A gas water heater with a standing pilot will keep working through an outage. One with an electric ignition or an electric tank will not come back on until the power does, and most will restart on their own once it's back.

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 tank itself has likely rusted through and is failing. Water heater tanks are lined, but once that lining fails the steel underneath corrodes, and a leak from the bottom usually means the tank has already started to fail. It can also be the drain valve or a fitting rather than the tank, which is worth checking first since that can be repaired. A leaking tank cannot be repaired and needs to be replaced.
- 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 reading the flame correctly and the gas valve shuts off the pilot as a safety measure. It can also be a dirty pilot tube or a draft blowing the flame out. A contractor can test the thermocouple and replace it if that is the cause.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Issues like a failed igniter, a clogged inlet filter, mineral buildup on the heat exchanger, or an error code from a sensor can usually be fixed without replacing the unit. A contractor can run the diagnostics to find which part is causing the problem.
