Cold winters and storm outages put strain on your water heater here
Dubuque County homes need heat from October through May, eight months of the year, and winter nights average 15°F from December through February. That kind of cold puts more demand on your water heater right alongside your furnace, since incoming water runs colder for most of the year and the burner or heating element has to work longer to keep up. That extra runtime is what wears down a burner assembly or a heating element over time.
The county has seen 24 winter storms and 118 damaging wind events over the past ten years, and storms like these cause power outages. Most water heaters come back on by themselves once power is restored, but if yours does not reheat and you are stuck with lukewarm or cold water afterward, that is a sign something needs a look.

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 once that happens the tank cannot be repaired, only replaced. Water pools at the base first because that's the lowest point, so a bottom leak usually means the tank has already been failing for a while. It can also be a loose drain valve or a fitting that's simply worked itself loose, so it's worth checking those before assuming the tank is done. A contractor can tell you which one you're dealing with.
- 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 correctly and shuts the gas off even though the pilot lit fine. A dirty pilot orifice or a draft reaching the pilot can cause the same problem. A standing pilot doesn't use electricity, so a power outage isn't the cause. A contractor can test the thermocouple and replace it if that's the issue.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. Mineral buildup on the heat exchanger, a failed igniter, or a clogged inlet filter are common issues and none of them require replacing the whole unit. Dubuque's water heaters run hard from October through May with cold groundwater coming in, so the heat exchanger works harder here than it would somewhere warmer. A contractor can flush and inspect the unit to find out what's actually wrong.
