Nine months of winter, then the power goes with it
Belfast homes need heat from September through May, nine months of the year. Waldo County has logged 79 winter storms and 34 damaging wind events over the past ten years, and in 2024, 54% of Maine households lost power for at least 24 hours.
A water heater usually rides out a short outage without trouble. Most electric units come back on by themselves once the power returns, and a gas unit with a standing pilot keeps running through the outage since the pilot doesn't need electricity at all. If your pilot has gone out on its own, or the water isn't hot once the power's back, that points to something else needing a look.

- Why is my water heater leaking from the bottom?
- Most of the time this means the tank itself has rusted through and is failing, not a fitting or valve that can be tightened. Water heaters corrode from the inside as the glass lining wears down over years of use, and once the steel underneath is exposed, it rusts and eventually leaks. A leak from the bottom of the tank means the tank needs to be replaced, not patched. If the water is coming from a pipe fitting or the drain valve near the bottom, that is a different problem and can often be repaired, so it is worth checking where the water is actually coming from before assuming the tank is done.
- 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 the pilot is lit. When it wears out or gets coated in soot, it can't sense the flame properly and shuts the gas off even though the pilot is burning. A weak pilot flame, a draft in the room, or a dirty pilot orifice can cause the same thing. A contractor can test the thermocouple and replace it if that's the issue.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Igniters, flow sensors, heat exchangers, and venting issues can usually be serviced without replacing the whole unit. Mineral buildup from hard water is a common cause of reduced flow or error codes, and flushing the unit often resolves it. A contractor can run the unit's diagnostics to find the actual fault before deciding whether repair or replacement makes more sense.
