What cold winters and power outages do to your water heater
Morrisville needs heat from September through May, nine months of the year, and winter nights average 10°F from December through February. A water heater sitting in an unheated basement or garage has to work against that cold the whole time, and the extra runtime wears on a heating element or burner sooner than it would in a warmer spot.
The county has also seen 40 winter storms and 38 damaging wind events over the past ten years, and statewide, 21% of households went at least 24 hours without power in 2024. Most electric water heaters come back on by themselves once power returns. A gas unit with a standing pilot does not need power to keep that pilot lit, but one with an electronic ignition may need to be relit by hand after an outage.

- Why is my water heater leaking from the bottom?
- The tank itself has likely rusted through from the inside and is starting to fail. Water heaters build up sediment over the years, and once the tank corrodes, the leak will only get worse. It could also be a loose drain valve or a fitting at the bottom, which a contractor can check before assuming the tank is done. If it is the tank, it needs to be replaced, not patched.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small part that senses the pilot flame and tells the gas valve to stay open. When it wears out, it can't confirm the flame is lit, so the gas shuts off even though the pilot was burning. A dirty pilot orifice or a draft blowing out the flame can also do this. A contractor can test the thermocouple and clean or replace it.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit can be fixed without replacing the whole thing. Mineral buildup on the heat exchanger is common and usually calls for a descaling flush. Igniter failures, sensor faults, and venting issues can also be repaired. A contractor will need to check the error code on the unit to know which part is at fault.
