Eight months of cold nights push it harder
Your water heater runs October through May here, the same eight months the heat is on. Winter nights average 22°F, and the colder the water coming into the tank, the longer the burner or the heating element has to run to bring it up to temperature. That extra runtime is what wears out an element or a burner assembly before its time.
Storms are part of living here too. Northampton County has seen 18 winter storms and 172 damaging wind events over the past ten years, and statewide, 15% of households lost power for a day or more in 2024. Most water heaters come back on by themselves once power is restored, but a gas water heater with an electronic ignition may need to be relit by hand.

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 failed. Inside the tank, water sits against steel day and night, and once corrosion works through, it lets water seep out the bottom and there is no patch for that. It can also be a loose drain valve or a fitting, which a contractor can check in a few minutes without touching the tank. If the leak is coming from 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 reason is a worn thermocouple, the small sensor that tells the gas valve the pilot is burning. Once it wears out, it fails to hold the valve open and the flame goes dark again after you let go of the knob. A dirty pilot tube or a draft in the area can cause the same thing. A contractor can test the thermocouple and replace it if that is the cause.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. Error codes usually point to something specific, like a flow sensor, an igniter, or mineral buildup on the heat exchanger, and a contractor can diagnose which one it is. Tankless units also need periodic descaling to keep the heat exchanger working properly, and skipping that is a common reason problems show up in the first place. Whether repair or replacement makes more sense depends on the unit's age and what's failing, which a contractor can assess in person.
