Warren winters put more strain on your water heater
Cold groundwater feeding into your tank has to work harder to reach set temperature from December through February, when nights average 21°F. That means longer burner or heating element run times, and parts that cycle more end up wearing out sooner. A failing thermocouple or heating element usually shows up as water that never gets hot, or runs out fast.
Power loss adds to this. Across Michigan, over a third of households lost power for 24 hours or more in 2024, and Macomb County has seen 16 winter storms and 99 damaging wind events over the past ten years. Most gas water heaters with a standing pilot keep working through an outage, but electric units and gas models with electronic ignition will not come back on until power is restored and someone relights or resets them.

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 that the tank itself has corroded through and is failing. Water heaters store hot water for years, and the inside of the tank slowly rusts even with a sacrificial anode rod working to slow it down. Once the steel gives way, water seeps out the bottom and the tank cannot be patched or sealed. A leak can also come from a loose drain valve or a fitting at the bottom, which a contractor can check before deciding the tank itself is the problem.
- Why won't the pilot light on my water heater stay lit?
- Most often the thermocouple has worn out and is no longer sensing that the pilot is lit, so it shuts the gas off. The thermocouple sits in the pilot flame and tells the gas valve to stay open. When it wears out or sits slightly out of position, it reads a false signal and cuts the flame even though the pilot lit fine. A weak pilot flame, a dirty pilot orifice, or a draft blowing the flame out can cause the same thing, so it takes a contractor to tell which one is happening.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable rather than a reason to replace the unit. The igniter, the flow sensor, and the heat exchanger are the parts that most often fail, and each can be tested and replaced on its own. Mineral buildup inside the heat exchanger is also common and is cleared with a descaling flush rather than a new part. A contractor can run the unit's error codes to find out which part is causing the trouble.
