Nine months of heat, and a grid that doesn't always hold
A water heater in Penobscot County works nine months of the year just to keep pace with the house around it, from September through May. Winter nights average 10°F, and a tank that's already tired has to work harder to bring water up to temperature when the incoming line is that cold.
Power is the other piece. More than half of Maine households went at least a day without power in 2024, and the county has logged 134 winter storms and 188 damaging wind events over the past ten years. A gas water heater with a standing pilot keeps making hot water through an outage. One that depends on power to ignite does not, until the power is back. Worth knowing which one you're installing, and what it means for the days the lights go out.

- How do I know it's time to replace my water heater?
- Age is the first thing to check, since a tank water heater has a rated lifespan and gets less reliable once it's past that. Rust colored water from the hot tap, a tank that's damp or wet at the base, or water that never gets as hot as it used to are all signs the tank itself is failing rather than just one part. A leaking tank won't get better, so if you see water pooling underneath, that one doesn't wait.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, since a tankless unit solves a different problem than a tank does. A tank stores a fixed amount of hot water and can run out partway through a shower or a load of laundry. A tankless unit heats water as it passes through, so it keeps up as long as you're within its flow rate. Whether it's worth switching for your house depends on your gas line, your electrical panel, and how the unit would be vented, and that's something a contractor should walk through with you.
- What changes when you install a tankless water heater?
- The biggest change is that hot water becomes limited by flow rate instead of tank size. A tank gives you a fixed amount of hot water before it runs out and needs to recover. A tankless unit keeps producing hot water as long as you're drawing it, but only up to a certain number of gallons per minute, so running two showers and a dishwasher at once can still strain it. Installation also usually means new venting, since tankless units vent differently than a tank does, and depending on the model it may need a larger gas line or a dedicated electrical circuit. A contractor can tell you what your specific setup would need.
