Cold groundwater keeps your water heater working harder here
Winter nights in Dauphin County average 24°F from December through February, and that cold runs straight into the water main. Your water heater has to work harder to bring that water up to temperature, and it does that work eight months a year, October through May. The burner or the heating element cycles more, and the thermostat and igniter or element see more wear than they would somewhere warmer.
Storms add another failure point. The county has seen 18 winter storms and 149 damaging wind events over the past ten years, and 15% of Pennsylvania households lost power for at least 24 hours in 2024. Gas water heaters with electronic ignition won't light without power, and if a storm knocks yours out, you will notice when the hot water runs out and does not come back.

- Why is my water heater leaking from the bottom?
- Most often the tank itself has rusted through and is failing from the inside. Water heaters corrode over the years, and once the tank starts to leak there is no patch or seal that fixes it, since the leak means the steel has already given way. Sometimes what looks like a tank leak is actually the drain valve or a fitting on top that has loosened, and those can be repaired. A contractor can tell you which one you have by drying the area and watching where the water shows up first.
- 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 stay open. When it wears out it can't hold that signal, so the valve shuts the gas off and the pilot goes out. A weak pilot flame, a draft reaching the pilot, or a dirty pilot orifice can cause the same thing. Since this involves the gas valve, it's worth having a contractor check it rather than repeatedly relighting it.
- Can a tankless water heater be repaired?
- Yes, most tankless problems are repairable. The heat exchanger, the flow sensor, the igniter and the venting are the parts that most often need attention, and each can usually be serviced or replaced on its own without replacing the whole unit. Mineral buildup inside the heat exchanger is common too, especially if the unit has never been descaled, and that can restrict flow or trigger error codes. A contractor can read the unit's error code and know which part it's pointing to.
