Cold groundwater and winter outages both work against your water heater
Water heaters in Centre County work harder from October through May, when incoming water runs cold and the unit has to raise it further to get hot water out of the tap. That extra work falls on the heating element or the burner, and over enough winters it's often the first part to fail. You notice it as water that never gets quite hot, or takes longer than it used to.
Winter storms add a second problem. Centre County has seen 27 winter storms and 168 damaging wind events over the past ten years, and statewide, 15% of Pennsylvania households lost power for 24 hours or more in 2024. A gas water heater with an electric ignition won't restart on its own once power comes back, and you're left with cold water until it's reset or repaired.

A new water heater would cut about $390 a year off hot water for a typical Pennsylvania 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 often the tank itself has corroded through and is leaking from the inside out. Water heaters have a glass lining inside the steel tank, and once that lining cracks, the tank rusts and starts to weep at a seam or fitting near the bottom. It can also be the drain valve or a loose fitting rather than the tank, which is worth checking first since those can sometimes be tightened or replaced. If the tank itself is leaking, it needs to be replaced, since a leaking tank cannot be sealed or 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 the flame is lit. When it wears out, it fails to sense the flame fast enough and the gas valve shuts off the pilot as a safety measure. A dirty pilot tube or a draft blowing the flame around can also cause this. A thermocouple is an inexpensive part to replace, but if it keeps happening after that, the gas valve itself may be the problem.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable rather than a reason to replace the unit. Common issues are mineral buildup on the heat exchanger, a failed igniter, or an error code pointing to a sensor or flow problem. Tankless units also need periodic descaling to flush out mineral deposits, especially where the water is hard, and skipping that maintenance is a common reason problems show up. A contractor can pull the error code and tell you which part is causing it.
