Plainfield asks a lot of a water heater from October through May
Groundwater coming into your house is already cold when winter sets in, and with nights averaging 22°F from December through February, your water heater works harder for eight months straight to make up the difference. The burner or element runs longer each cycle, and the tank never really gets a break.
Power is the other issue. Statewide, 17% of households lost power for at least 24 hours in 2024, and Hendricks County has logged 10 winter storms and 71 damaging wind events over the past ten years. When the power drops and comes back, a gas water heater with an electronic ignition needs to relight on its own, and not all of them do. If yours has a standing pilot, it never needed power in the first place. Either way, a water heater that won't recover after an outage is a common reason for the call.

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 it means the tank itself has failed inside and is leaking from a crack or rust hole in the steel. Water expands every time it heats, and years of that stress combined with sediment sitting in the bottom of the tank wear through the lining. It can also be the drain valve, a fitting, or the temperature and pressure relief valve doing its job because the tank is overheating. A contractor can tell you which one it is by looking at where the water is actually coming from, but if it is the tank itself, the water heater needs to be replaced, not repaired.
- 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 sending gas. Once it wears out, it can't sense the flame properly and shuts the gas off even though the pilot lit fine a moment ago. A dirty pilot orifice or a draft in the area can also blow the flame out. A standing pilot doesn't use any electricity, so this isn't a power problem, and a contractor can usually confirm which part is at fault and replace it.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. Mineral buildup on the heat exchanger, a failed igniter, a clogged inlet filter, or an error code from a sensor are all things a contractor can diagnose and fix without replacing the unit. Tankless units also tend to log an error code when something goes wrong, which points straight to the part that needs attention. A full replacement is usually only needed when the heat exchanger itself has failed.
