Cold winters and power outages both take a toll here
Sterling winter nights average 17°F from December through February, and that cold reaches the groundwater feeding your tank. The colder the incoming water, the longer your burner or heating element has to run to bring it up to temperature, and that extra runtime wears on the thermostat and the heating element or burner itself over the eight months a year homes here need heat.
Whiteside County has seen 21 winter storms and 58 damaging wind events over the past ten years, and storms like these cause power outages. Statewide, 16% of Illinois households went at least 24 hours without power in 2024. Most water heaters come back on by themselves once power returns. If yours has a standing pilot, that flame will not relight itself, and you will find the water has gone cold until it is lit by hand.

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 reason is that the tank itself has corroded through and is failing. Sediment builds up on the bottom of the tank over years, and it slowly wears through the steel until water starts to seep out. Once a tank is leaking this way, patching it does not work. A leak can also come from the drain valve or a fitting near the bottom, and those can sometimes be tightened or replaced. A contractor can tell you which one you are dealing with by looking at where the water is actually coming from.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and can no longer sense that the pilot is burning, so the gas valve shuts it off. A weak or dirty pilot flame, a draft near the burner, or a clogged pilot tube can cause the same thing. Replacing the thermocouple fixes most cases. If the pilot relights and then goes out again within a minute or two, that points to the thermocouple rather than something else.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Common issues are a dirty inlet filter, a flame sensor or igniter that has failed, or mineral buildup on the heat exchanger from hard water. A contractor can flush the unit, clean the filter, or replace the failed part depending on what is causing the problem. Whether repair makes sense over replacement depends on the age of the unit and what has already failed on it.
