Eight months of cold water coming in
Your water heater works October through May here, and on winter nights averaging 21°F, the water coming into the tank is as cold as it gets. That means longer burner cycles, or the electric element running longer, to bring the same tank up to temperature, and more wear on whichever one your unit uses.
Power outages add to the strain. Statewide, a third of Michigan households went at least 24 hours without power in 2024. A gas water heater with a standing pilot will keep working through an outage. One with electronic ignition will not light until power is back, and if the outage hits during a cold stretch, you will notice the cold water right away.

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 leaking from the inside out, and that means replacement, not repair. Water expands as it heats, and once a tank corrodes it can no longer hold that pressure. But bottom leaks can also come from a loose drain valve, a bad temperature and pressure relief valve, or fittings that have loosened over time, and those can often be fixed. A contractor can tell you which one you have by looking at where the water is actually coming from.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and is no longer sensing the flame, so the gas valve shuts it off as a safety measure. It can also mean a weak pilot flame that the thermocouple can't read, or a draft in the area that's blowing the flame out. Dirt or soot clogging the pilot orifice will cause the same problem. A contractor can test the thermocouple and clean or replace the parts that are keeping the flame from holding.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. A clogged flow sensor, a failed igniter, a buildup of scale on the heat exchanger, or an error code from a bad sensor are all things a contractor can diagnose and fix without replacing the whole unit. Regular descaling helps prevent some of these issues from starting in the first place. Whether repair makes sense over replacement depends on the age of the unit and what's actually failed, which a contractor can tell you after looking at it.
