Water heaters in Warren County work through a long, cold winter
Your water heater runs harder from October through April, when incoming water is colder and the burner or heating element has to work longer to keep up. Add in nights that average 29°F from December through February, and a unit that was already due for service starts showing it. The thermostat cycles more, the burner or element runs longer, and older parts wear faster than they would in a milder climate.
Power matters too. Nearly a quarter of Kentucky households went at least a day without power last year, and Warren County has seen 11 winter storms and 98 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep working through an outage. One with electronic ignition or an electric unit will not come back on until the power does, and if it does not relight or reset on its own, that is when you notice there is no hot water.

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 most common cause is the tank itself has rusted through from the inside and is failing. Sediment builds up on the bottom of the tank over the years and traps moisture against the steel, and once it corrodes enough to leak, the tank cannot be patched or sealed. A leak can also come from the drain valve at the bottom or from fittings above the tank running down the side, and those can sometimes be repaired. A contractor needs to look at where the water is actually coming from before you know which one you have.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and is no longer sensing that the pilot is lit, so it shuts off the gas as a safety measure. This part sits right in the pilot flame and wears down with use over years. A weak or dirty pilot flame, a draft near the burner, or a gas supply problem can cause the same symptom. A contractor can test the thermocouple and flame directly and replace it if that is the cause.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Common issues include mineral buildup on the heat exchanger, a failed igniter, a blocked vent, or an error code pointing to a specific sensor or part. Hard water buildup is the most frequent cause of reduced performance in these units, and it can often be cleared with a descaling flush rather than replacing anything. A contractor can read the unit's error code and diagnose which part or issue is behind it.
