Nine months of heating season puts real demand on your water heater
Belfast homes need heat from September through May, and the water heater is part of that load the whole time. Winter nights averaging 14°F mean the incoming water is colder too, so the tank works harder to bring it up to temperature.
Waldo County has seen 79 winter storms and 34 damaging wind events over the past ten years, and across Maine, more than half of households lost power for at least 24 hours in 2024. A gas water heater with a standing pilot keeps working through an outage. One that relies on electronic ignition or a powered vent will not, until power is back. The new unit going in should match the size of the tank being replaced or installed, since the federal minimum efficiency for storage water heaters is set separately for each size and draw pattern, not as one number for every tank.

- How do I know it's time to replace my water heater?
- Look at the tank first. Rust colored water from the hot tap, a tank rusting on the outside, or water pooling underneath mean the tank itself is failing, and a tank cannot be repaired, only replaced. If it's old enough that you don't remember installing it, that age alone is worth asking a contractor about. If it's still making hot water but making noise, taking longer to recover, or running out faster than it used to, a contractor can tell you whether that's the heating element, the thermostat, or the tank giving out.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your old tank failing. A tankless unit heats water as you use it instead of storing it, so you get hot water on demand rather than filling and reheating a tank all day. Winters here push the incoming water temperature down close to 14°F outside air, and a tankless unit has to raise that water further than one would in a milder place, which is worth asking about when a contractor sizes the unit. It's a bigger change than a straight tank swap, since the gas line, venting, or electrical feeding it usually needs to match what the new unit requires, so get a contractor to walk through what your home would need before deciding.
- What changes when you install a tankless water heater?
- The unit takes up much less space, since there's no tank to store hot water in. Gas fired tankless units generally need a larger gas line and their own venting to the outside, different from what a tank system used. Electric tankless units draw a lot of power for a short time, so the electrical circuit feeding it often has to be upgraded to handle that load. Because tankless units heat water on demand instead of storing it, they don't run out the way a tank does, but a contractor still has to size the unit to the number of fixtures it will serve at once.
