Chambersburg winters put a long strain on your water heater
Groundwater coming into your house is cold for eight months of the year here, from October through May. Your water heater has to work harder and longer to bring it up to temperature, and that extra runtime wears on the heating element or burner and the thermostat that controls it. You notice it as water that takes longer to get hot, or runs out faster than it used to.
Franklin County also sees real winter weather, with 16 winter storms and 78 damaging wind events over the past ten years. Storms like that knock out power, and 15% of Pennsylvania households lost power for a full day or more in 2024. An electric water heater will come back on once power returns, but a gas unit 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?
- The most common cause is the tank itself failing from the inside. Sediment builds up over years of use, and it holds moisture against the steel until it rusts through and starts weeping at a seam or fitting. It can also be a loose drain valve or a fitting that has simply worked itself loose, which is worth checking before you assume the worst. If the tank itself is rusted through, it needs to be replaced, since there is no repair for a cracked tank.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and no longer tells the gas valve the pilot is lit, so the valve shuts the gas off as a safety measure. A dirty or clogged pilot orifice can cause the same problem by starving the flame. Wind or a draft reaching the pilot from a nearby vent can also blow it out repeatedly. A contractor can test the thermocouple and clean or replace the parts that are causing it.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater can be repaired rather than requiring a full replacement. Common repairs include descaling the heat exchanger where hard water has left mineral buildup, replacing an igniter or flame sensor, and clearing a blocked intake or exhaust vent. Because tankless units rely on sensors and electronic controls to fire correctly, a contractor needs to diagnose which part has failed before repairing it.
