Long cold winters put months of strain on your water heater
Carlisle homes run their heat from October through May, eight months of the year. Through the coldest stretch, December through February, nights average 24 degrees. Your water heater sits through the same cold, working to keep up night after night, and that steady demand wears on the heating element or burner assembly and on the thermostat that controls it.
Cumberland County has seen 16 winter storms and 89 damaging wind events over the past ten years, and storms like these knock out power. When that happens, an electric water heater or a gas unit with an electronic igniter shuts down until power comes back. A standing pilot keeps burning through the outage. Either way, you'll notice it first as water that won't get hot or a tank that takes much longer to recover between uses.

- Why is my water heater leaking from the bottom?
- Most often it means the tank itself has failed inside and is starting to rust through. Sediment builds up on the bottom of the tank over years, and it traps heat against the steel until a weak spot gives way. Water under the tank can also come from a loose drain valve or a fitting that has worked itself loose, and those are worth checking first since they can be fixed. But once the tank itself is leaking, it needs to be replaced, not 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 tells the gas valve the pilot is burning. When it wears out it stops sensing the flame correctly and shuts the gas off even though the pilot is lit. A dirty pilot orifice or a draft in the area can also blow the flame out or keep it from sensing right. A thermocouple is a simple part to replace, so if relighting it keeps failing, that is the likely fix.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. Mineral buildup on the heat exchanger is common and is cleared by flushing the system. Igniters, flow sensors, and exhaust vents can all fail on their own and get replaced without touching the rest of the unit. A contractor can tell you after looking at it whether the fix is worth it or whether the unit has reached the end of its life.
