What Danville winters do to your water heater
Groundwater coming into your house is cold most of the year here, and from October through May your water heater has to work harder to get it to temperature. That extra runtime adds up over eight months, and it wears on the heating element and the thermostat that controls it.
Winter storms bring another problem. Vermilion County has logged seven winter storms and 163 damaging wind events over the past ten years, and outages follow both. Statewide, 16% of Illinois households lost power for 24 hours or more in 2024. Gas water heaters with a standing pilot stay lit through an outage, but most newer ones need power for the igniter and controls, so the tank goes cold until power is back and someone relights it.

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 from the inside and is starting to fail. Water heaters corrode from the inside out over the years, and once the tank shell gives way, no seal or fitting will stop the leak. It can also be the drain valve or a loose fitting, which a contractor can check before assuming the tank is done. If the leak is coming from underneath the tank itself rather than a pipe or valve, the tank needs to be replaced.
- Why won't the pilot light on my water heater stay lit?
- The thermocouple is usually the reason. It is the small sensor that sits in the pilot flame and tells the gas valve the pilot is lit. Once it wears out or sits out of position, it reads the flame as out and shuts the gas off, even while the pilot is still burning. A dirty pilot tube or a draft can do the same thing, so a contractor will check both before replacing anything.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable rather than a reason to replace it. The igniter, the flow sensor, and the heat exchanger are the parts that most often need attention, and each can usually be serviced or replaced on its own. Mineral buildup inside the heat exchanger is a common cause of reduced hot water or error codes, especially over years of use. A contractor can run the unit's diagnostics to find which part is causing the problem.
