Rockland winters are hard on a water heater
Groundwater coming into your house is cold most of the year, and from December through February, when nights average 16°F, your water heater works harder to make up that difference. The burner or heating element runs longer and more often to hold the tank at temperature, and that extra run time wears on the thermostat and the heating element itself.
Power is not always reliable here. Statewide, more than half of Maine households lost power for at least a day in 2024, and Knox County has seen 45 winter storms and 18 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep working through an outage, but an electric unit or one with an electronic ignition will not, and when the power comes back on, some units need to be relit or reset by hand.

- Why is my water heater leaking from the bottom?
- Most of the time this means the tank itself has failed. Water heater tanks corrode from the inside over years of use, and once rust eats through the steel, no fitting or valve can be tightened to stop it. Water pooling under the tank, rather than dripping from a pipe above it, is the sign that the tank is the source. A leaking tank needs to be replaced, not repaired, since there is no way to patch a hole in the steel.
- 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 keep the gas flowing. When it wears out, it can't hold that signal, so the valve shuts the gas off and the flame dies. A dirty or misaligned pilot orifice can cause the same thing. Either part can be checked and replaced by a contractor without needing a new water heater.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairs, not replacements. Issues like a fouled heat exchanger from mineral buildup, a failed igniter, or a blocked vent are things a contractor can clean or replace. Tankless units also run diagnostic codes on a display, which point straight to the part causing trouble. Full replacement is usually only needed when the heat exchanger itself has cracked or corroded through.
