Cold months mean longer water heater runs
Homes here need heat from October through May, eight months of the year. That same cold reaches the water coming into your tank, so the burner or heating element runs longer to bring it up to temperature. Winter nights average 16°F from December through February, and that steady demand wears on the thermostat and heating element in an electric unit, or the burner assembly and thermocouple in a gas one.
Winnebago County has seen 19 winter storms and 131 damaging wind events over the past ten years, and in 2024, 16% of Illinois households lost power for at least 24 hours. A gas water heater with a standing pilot will keep heating through an outage. One with electric ignition won't light until the power is back, and an electric water heater stops heating until then too, though most start back up on their own once power returns.

A new water heater would cut about $60 a year off hot water for a typical Illinois 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, and once that happens the tank has to be replaced, not patched. It can also be a fitting or drain valve leaking down the side and pooling at the bottom, which a contractor can repair without replacing the tank. Shut off the water and power to the unit and have someone look at it before the leak gets worse or reaches the floor.
- Why won't the pilot light on my water heater stay lit?
- A pilot that won't stay lit is usually a sign the thermocouple has worn out. That's the small part that senses the flame and tells the gas valve to keep supplying gas. It can also mean a draft is blowing the flame out or the gas valve itself is failing. A contractor can test the thermocouple and replace it if that's the cause.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater can be repaired without replacing the whole unit. Common repairs include descaling the heat exchanger, replacing an igniter, or fixing an error code tied to a sensor. A contractor can run the unit's diagnostics to find out which part is causing the problem.
