Cold winters mean your water heater runs longer here
Belleville homes need heat from October through April, seven months a year, and winter nights average 26°F from December through February. Your water heater is working through all of it, right alongside your furnace, heating water for a house that is losing warmth outside. That steady demand falls on the heating element or burner and on the thermostat that controls it.
St. Clair County has seen 9 winter storms and 84 damaging wind events over the past ten years, and storms like these knock out power. Across Illinois, 16% of households lost power for 24 hours or more in 2024. An electric water heater usually comes back on by itself once power returns. A gas unit with an electronic igniter may not relight on its own, and you will notice when the hot water runs out.

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 of the time this means the tank itself has rusted through, and there's no fixing that, only replacing it. Water forms inside the tank over years, and once it eats through the steel, the leak won't stop or slow down. Before you assume the worst, check the drain valve at the bottom and the fittings above it, since those can leak on their own and get replaced without touching the tank. If the water is coming from underneath the tank itself, plan on a new water heater.
- Why won't the pilot light on my water heater stay lit?
- The most common reason is a worn thermocouple, the small part that sits in the pilot flame and tells the gas valve it's safe to keep the gas flowing. When it wears out, it stops sensing the flame correctly and shuts the gas off even though the pilot is lit. A dirty pilot orifice or a draft blowing the flame around can also cause it. A contractor can test the thermocouple in a few minutes and replace it if that's the cause.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Mineral buildup on the heat exchanger, a failed igniter, a bad flow sensor, or an error code from the control board are all things a contractor can diagnose and fix without replacing the whole unit. Regular descaling helps prevent the buildup problems in the first place, especially with harder water. A contractor will need to look at the specific error or symptom to know what's going on.
