St. Clair County winters put your water heater to work harder than most
Cold groundwater in December through February means your water heater has to work harder to bring it up to temperature, and it does that work more often since the incoming water is colder for eight months of the year. That extra cycling wears on the burner assembly and the thermostat sooner than it would somewhere warmer.
Power is the other issue. More than a third of Michigan households lost power for a full day or longer in 2024, and St. Clair County has seen 13 winter storms and 82 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep running through an outage. One with an electric igniter will not relight on its own, and you will notice when the hot water runs out and does not come back.

A new water heater would cut about $50 a year off hot water for a typical Michigan 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 of the time this means the tank itself has rusted through from the inside and is starting to fail. Sediment builds up at the bottom of the tank over years, and once it wears through the lining, water finds its way out. It can also be a loose drain valve or a fitting that has come loose, which a contractor can check in a few minutes. If the leak is coming from the tank wall itself rather than a fitting, the tank needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- This usually points to the thermocouple, the small sensor that sits in the pilot flame and tells the gas valve it is safe to keep the gas flowing. When it wears out or gets coated in soot, it stops sensing the flame correctly and shuts the gas off. A weak or dirty pilot orifice can cause the same thing, and so can a draft blowing the flame around. A contractor can test the thermocouple in a few minutes and replace it if that is 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 issues are a clogged inlet filter, mineral buildup on the heat exchanger from hard water, or a failed igniter, and all of these can be serviced. A contractor can flush the unit and test the parts to find out which one is causing the problem. Whether repair makes sense over replacement depends on the age of the unit and what's failing, which a contractor can tell you after looking at it.
