Cold groundwater and power outages both add to the load
From October through April your water heater is working against cold incoming water, and on nights near 28 degrees that groundwater runs cold too. The heating element or burner has to work harder and longer to get water up to temperature, and that extra runtime is what wears out an element or burns through a thermocouple sooner than it should.
Bullitt County has seen 14 winter storms and 58 damaging wind events over the past ten years, and statewide, about a quarter of households lost power for a full day or more in 2024. A gas water heater with a standing pilot will keep working through an outage. One with electronic ignition will not light until power is back, and if it does not come back on by itself, that points to a control board or ignition problem worth checking.

A new water heater would cut about $270 a year off hot water for a typical Kentucky 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 from the inside. Sediment builds up at the bottom of the tank over the years and eats away at the steel until it cracks. Once the tank is leaking like this it can't be patched or repaired, it needs to be replaced. Water pooling underneath can also come from a loose drain valve or a fitting at the bottom, which a contractor can check before ruling out the tank.
- 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 fails, the valve shuts off the gas as a safety measure even though the flame is fine. A dirty pilot orifice or a draft blowing into the pilot chamber can cause the same problem. A contractor can test the thermocouple and replace it, which usually solves it.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Mineral buildup on the heat exchanger is common and is cleared with a descaling flush, especially important since these units run hotter and tighter than a tank model. Ignition failures, error codes, and flow sensor issues can usually be diagnosed and fixed without replacing the unit. A contractor can look at the specific error and tell you whether a part needs replacing or if it just needs service.
