What winter in Calais does to a water heater
Cold groundwater comes into your tank all winter, and from December through February it has to fight nights averaging 14°F just to hold a set temperature. That means longer burner or element run times, and more wear on the thermostat and heating element that carry the load.
Maine households lose power often, more than half went at least a day without it in 2024, and Washington County sees its share of the storms behind that. A gas water heater with a standing pilot will keep running through an outage. One with electronic ignition will not relight on its own, so if your water goes cold right after the power comes back, that is usually why.

- Why is my water heater leaking from the bottom?
- The most common cause is the tank itself, rusted through from the inside after years of holding water. Once it starts, it will not stop or seal itself, and it usually gets worse. It can also be a loose drain valve or a failed fitting near the bottom, which a contractor can check before assuming the tank is done. If the leak is coming from the tank wall itself, the water heater needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- Most of the time this means the thermocouple has worn out and can no longer sense the flame, so the gas valve shuts it off. A draft near the burner or a dirty pilot orifice can also blow it out or choke it. This is worth fixing soon in a place where nights run near 14 degrees for months at a time, since a water heater that will not stay lit means no hot water when you need it most. A contractor can test the thermocouple and replace it if that is the cause.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Common issues are a clogged inlet filter, mineral buildup on the heat exchanger, or a failed igniter, and a contractor can clean or replace these parts. Hard water speeds up the buildup, so a unit that has never been descaled is more likely to need service. A contractor can flush the system and test the components to find out which part has failed.
