Cold water and long winters wear on your water heater here
Water heaters in Webster County run hard from October through May, eight months of the year. Groundwater coming in is already cold, and on winter nights averaging 13°F from December through February, the burner or heating element has to run longer to bring a tankful up to temperature. That extra runtime wears on the heating element and thermostat in an electric tank, and on the burner assembly in a gas one.
The county has also logged 31 winter storms and 39 damaging wind events over the past ten years, and 15% of Iowa households lost power for 24 hours or more in 2024. An electric water heater stops heating the moment power drops and starts again on its own once it is back. A gas water heater with a standing pilot keeps running through the outage, but one with electric ignition will not relight itself. Either way, you notice it at the tap, when the hot water runs out faster than usual or does not come at all.

A new water heater would cut about $50 a year off hot water for a typical Iowa 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 tank itself has rusted through and is failing. Water heaters have a steel tank with a glass lining inside, and once that lining cracks, the steel underneath rusts and eventually leaks. A drain valve or fitting can also leak and look like the tank is the problem, so it's worth checking those first before assuming the worst. If the tank is the source, it needs to be replaced. It won't seal itself and it won't get better.
- Why won't the pilot light on my water heater stay lit?
- Most of the time this is the thermocouple. It's a small sensor that sits in the pilot flame and tells the gas valve it's safe to keep the gas flowing. When it wears out or gets coated with soot, it stops sensing the flame correctly and shuts the gas off, even though the pilot lit just fine a moment ago. A dirty pilot orifice or a draft in the room can also blow the flame out. A contractor can test the thermocouple and replace it if that's the cause.
- Can a tankless water heater be repaired?
- Yes. Most problems come down to a few things. The igniter fails. The flow sensor fails. Mineral buildup collects inside the heat exchanger from hard water and blocks it. A contractor can flush the unit or replace the part that's failed. Whether repair or replacement makes more sense depends on the age of the unit and what's actually gone wrong, and a contractor can walk through that once they've looked at it.
