Waukegan winters push your water heater harder

Cold groundwater in December through February means your water heater works harder to hit the same setpoint. That extra runtime adds up over eight months of heating season, and it wears on the heating element and thermostat first. You notice it as water that used to be hot running lukewarm, or a recovery time that used to be quick now taking a while.

Lake County has seen 20 winter storms and 138 damaging wind events over the past ten years, and power loss is part of that. Statewide, 16% of Illinois households lost power for 24 hours or more in 2024. Most electric water heaters come back on by themselves once power returns, but a gas unit with a standing pilot needs someone to relight it, and one that has gone out won't give you hot water until it is.

A new water heater would cut about $60 a year off hot water for a typical Illinois home.

  • A new high-efficiency gas water heater$130 a year
  • A heat pump water heater$140 a year
  • An older gas water heater$190 a year

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 is failing. Sediment builds up on the bottom of the tank over years, and the steel corrodes underneath it until it gives way. Once a tank is actually leaking, it needs to be replaced, not patched. A wet spot under the water heater can also come from a loose drain valve or a fitting at the top, so a contractor will check those before condemning the tank.
Why won't the pilot light on my water heater stay lit?
The most common cause is a worn thermocouple, the small sensor that sits in the pilot flame and tells the gas valve the flame is lit. When it wears out it can't confirm the flame anymore, so the valve shuts the gas off. A dirty pilot orifice or a draft blowing the flame out can cause the same thing. A contractor can test the thermocouple in a few minutes and replace it if that's the problem.
Can a tankless water heater be repaired?
Yes, most tankless problems are repairs, not replacements. A clogged inlet filter, a buildup of scale on the heat exchanger, or a failed igniter are all things a contractor can fix without replacing the unit. Error codes on the display usually point straight to the part that's causing trouble. Replacement only comes up when the heat exchanger itself has failed.
