What Marion County winters do to a water heater
Your water heater works harder from October through May, when the water coming into the tank starts out cold and the burner or element has to make up more ground before it reaches temperature. On winter nights that average 23°F, that gap is at its widest, and the unit runs longer each time it recovers.
Marion County has also logged 12 winter storms and 140 damaging wind events over the past ten years, the kind that can knock out power for a stretch. A gas water heater with a standing pilot keeps working right through an outage. One with electronic ignition, or an electric water heater, will not heat water until power is back, though most reset and start working again on their own once it is.

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?
- The tank itself has likely rusted through from the inside and is starting to fail. Water heaters corrode from the inside over years of use, and once the tank wall is breached, no seal or fitting will stop it. It could also be a loose drain valve or a fitting the water is running down from higher up, so it is worth drying the tank off and watching where the water first appears. If the leak traces back to the tank itself, the water heater needs to be replaced rather than repaired.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn out thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out, it fails to hold the valve open and the flame goes out soon after you let go of the knob. A thermocouple is a low cost part to replace and usually solves the problem on its own. If a new thermocouple does not fix it, the gas valve itself may need to be replaced, which a licensed contractor can test for.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Common issues include a clogged inlet filter, a buildup of scale on the heat exchanger, or a failed igniter, and all of these can be serviced without replacing the unit. Tankless units also run diagnostic error codes, which point a technician straight to the failing part. A full replacement is usually only needed when the heat exchanger itself has cracked or corroded through.
