Cold groundwater keeps your water heater working hard
Carmel winters push incoming water temperature down, and your water heater has to make up that difference every time someone runs a shower or starts the dishwasher. From October through May, that is eight months where the burner or heating element is working harder and longer to get water up to temperature. That extra runtime wears on the heating element in an electric unit or the burner assembly and thermocouple in a gas one.
Power matters too. In Indiana, 17% of households lost power for 24 hours or more in 2024, and the county has seen 69 damaging wind events over the past decade. A gas water heater with a standing pilot will keep working through an outage. One with electric ignition will not light again until power is back, and you may need to relight it yourself.

A new water heater would cut about $50 a year off hot water for a typical Indiana 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?
- Most of the time this means 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 corrodes and the tank starts to weep water at a seam or fitting near the base. Sediment that settles in the bottom of the tank speeds this up over the years. A leak from the tank itself does not get repaired, the water heater needs to be replaced. The other possibility is a loose drain valve or a fitting that just needs to be tightened or resealed, which a contractor can check before assuming the tank is done.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small sensor that sits in the pilot flame and tells the gas valve it is safe to keep the gas flowing. When it wears out, it fails to sense the flame correctly and shuts the gas off, so the pilot goes out. A dirty or clogged pilot orifice can cause the same thing by making the flame too small to reach the thermocouple. Both are inexpensive parts to replace. If the pilot won't stay lit even with a new thermocouple, the gas valve itself may need to be replaced.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Common issues are a buildup of mineral scale on the heat exchanger, a failed igniter, a clogged inlet filter, or an error code pointing to a specific sensor or board. A contractor can flush the unit to clear scale, which matters most in areas with hard water, and replace individual parts like the igniter or flow sensor without needing to replace the whole unit. Tankless units generally have a longer service life than tank water heaters, so repair is usually worth it unless the unit is quite old.
