What Bay City winters do to your water heater
Groundwater coming into your house is already cold when it gets here, and from October through May your water heater has to work harder to bring it up to temperature. That extra work falls on the heating element in an electric unit, or the burner and thermocouple in a gas one. Over enough cold months, those parts wear out faster than they would somewhere warmer.
Bay County has seen 49 damaging wind events and 12 winter storms over the past ten years, and across Michigan a third of households lost power for a day or more in 2024. When the power drops, an electric water heater stops heating until it comes back, and most units pick up again on their own once it does. Gas water heaters with a standing pilot keep running through the outage, but if yours has an electronic ignition, it will need power to relight. Either way, a storm that knocks the power out for a day is enough to leave you without hot water until it's restored.

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 often the tank itself has rusted through and is failing. Water heater tanks are lined, but once that lining cracks the steel underneath corrodes, and once it leaks the tank cannot be patched or sealed. It can also be a loose drain valve or a fitting at the bottom, which a contractor can check before assuming the tank is done. If the leak is coming from the tank itself, the water heater needs to be replaced.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out it stops sensing the flame and shuts the gas off as a safety measure, even though the pilot lit fine a moment ago. It can also be a dirty pilot orifice or a draft blowing the flame out. A thermocouple is inexpensive to replace and is the first thing a contractor will test.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Igniters, flow sensors, and heat exchangers can all be replaced without swapping out the whole unit. Mineral buildup from hard water is one of the most common issues, and it can usually be cleared with a descaling flush rather than a new unit. A contractor can look at the error code the unit is showing and tell you what's actually wrong with it.
