Eight months of winter push your water heater harder
Cedar Rapids homes run the furnace from October through May, eight months of the year, and the water heater is working right alongside it through nights that average 15°F in December through February. That long stretch means more cycles on the heating element or burner, and more wear on the parts that keep it firing.
Power matters too. Fifteen percent of Iowa households went at least a day without power last year, and this county has seen 30 winter storms and 156 damaging wind events over the past ten years. Most water heaters come back on by themselves once power returns, but a unit with electronic ignition still needs that ignition system working to relight. When it doesn't, you find out at the tap, with water that never warms up.

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 has likely rusted through from the inside and is starting to fail. Water heaters corrode over years of heating and reheating, and once the tank itself has a hole, there is no patch or seal that fixes it. A leak could also be coming from a loose drain valve or a fitting at the bottom, which a contractor can tighten or replace. The only way to know which one you have is to have someone look at it, since a tank leak means replacement and a fitting leak does not.
- 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 can't confirm the flame anymore, so the gas valve shuts off the pilot as a safety measure. A dirty pilot orifice or a draft near the burner compartment can cause the same thing. A contractor can test the thermocouple and replace it if that's the problem, since it's not something you can safely rebuild on your own.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Common issues are a clogged inlet filter, mineral buildup on the heat exchanger, or a failed flow sensor or igniter, and all of those can be serviced or replaced individually. Because these units have more electronic parts than a tank water heater, a contractor needs to diagnose which part is actually failing before doing any work.
