What Flint winters do to a water heater
Your water heater works harder from October through May, eight months of the year, than it does the rest of the time. Cold groundwater coming in means longer burner cycles or longer element run time to get the same hot shower, and that extra work adds up over a Genesee County winter.
The power behind it is not always steady either. Genesee County has seen 16 winter storms and 71 damaging wind events over the past ten years, and across Michigan, a third of households lost power for at least 24 hours in 2024. A gas water heater with an electronic igniter will not relight on its own once power drops, so when it comes back on, you may find no hot water until the pilot is relit by hand.

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?
- The most common reason is a failing tank. Water heater tanks corrode from the inside over years of use, and once the metal gives way the leak usually shows up at the bottom seam or where fittings enter the tank. It can also be a loose drain valve or a failed pressure relief valve dripping down the side and pooling underneath, which is worth checking before assuming the tank itself is bad. A leaking tank on a water heater does not get repaired. Once the tank is compromised, it needs to be replaced.
- 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 sensor that sits in the pilot flame and tells the gas valve it's safe to keep gas flowing. When it fails, the valve shuts the gas off as soon as you let go of the button, even though the flame was lit a second ago. A dirty pilot orifice or a draft blowing the flame around can cause the same symptom. A licensed contractor can test the thermocouple and replace it if it's the cause.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Common issues include a clogged inlet filter, a failed igniter, scale buildup on the heat exchanger, or a faulty flow sensor, and a contractor can replace or clean these parts without swapping out the whole unit. Tankless units also run diagnostic codes that point to the specific fault, which makes it easier to know what's actually wrong before any work starts. Replacement usually only comes into play when the heat exchanger itself has failed.
