Cold groundwater and long winters wear a water heater down here in Boone County
Your water heater works harder here because the water coming into it starts cold. With winter nights averaging 14°F from December through February, the tank has to work harder just to bring water up to a usable temperature, and it does that for eight months of the year, October through May. That extra runtime wears on the heating element and the thermostat sooner than it would somewhere warmer.
Power loss adds another layer. Iowa saw 15% of households lose power for 24 hours or more in 2024, and Boone County has logged 25 winter storms and 37 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep running through an outage. One with an electronic ignition won't, and when the power comes back, it usually needs to be relit by hand. If your water heater has gone cold after a storm and stayed that way, that's often why.

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 from the inside. Water heater tanks are lined, but once that lining breaks down the steel underneath starts to corrode, and once it's leaking, the tank can't be repaired, only replaced. A puddle at the bottom can also come from a loose drain valve or a fitting that's worked itself loose, both of which a contractor can check before assuming the worst. If the leak is coming from the top or from a pipe connection, that's a different problem and often a fixable one.
- 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 shuts the gas off even though the flame is lit. A dirty pilot orifice or a draft in the area can also blow the flame out or keep it from sensing correctly. A thermocouple is a straightforward part for a contractor to replace, so this usually isn't a sign the whole unit is failing.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems come down to individual parts, like the igniter, a flow sensor, or the heat exchanger, and those can be replaced without replacing the whole unit. Mineral buildup from hard water is another common issue, and it can often be flushed out rather than requiring new parts. A contractor can look at the error code the unit is showing and tell you which of these it is.
