Cold winters and power that doesn't always stay on
Your water heater works hardest from October through May, when incoming water runs cold and the tank has to make up more ground to get hot water out of the tap. Winter nights averaging 16°F push it further still, and a unit already working overtime has less room to cover for a failing part.
Pottawattamie County has seen 16 winter storms and 56 damaging wind events over the past ten years, and across Iowa 15% of households lost power for a full day or more in 2024. A gas water heater with a standing pilot will keep running through an outage, but one with an electric igniter or a powered control board will not relight on its own. If the power comes back and you still have no hot water, that is 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 from the inside and is cracked. Water heaters have a glass lining inside the steel tank, and once that lining fails, the steel underneath corrodes and eventually lets water seep out at the bottom. This isn't something a contractor can patch, since the tank is sealed. A leak can also come from a loose drain valve or a fitting at the bottom, which is a repair rather than a replacement, so it's worth having someone check before assuming the worst.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and can no longer sense that the pilot is burning, so the gas valve shuts it off as a safety measure. It could also be a weak pilot flame from a dirty orifice, or a draft blowing the flame out. A contractor can test the thermocouple and replace it if that's the cause, which is a common repair on older units.
- Can a tankless water heater be repaired?
- Yes. Tankless units have a heat exchanger, igniter, and flow sensor that can each be tested and replaced on their own, and most problems trace back to one of those parts or to mineral buildup inside the exchanger. A contractor can flush the unit or swap the failed part depending on what's wrong. The exact repair and what it involves will depend on the unit, so a contractor will need to look at it to say for sure.
