Nine months a year of hard use in Bath
Your water heater works from September through May here, nine months of the year. Winter nights average 16°F, and cold groundwater means the tank has to work harder to bring water up to temperature every time someone runs a shower or starts the dishwasher.
Sagadahoc County sees its share of winter storms and damaging wind, and across Maine more than half of households lost power for at least a day in 2024. A gas water heater with a standing pilot will keep running through an outage. An electric one will come back on by itself once power returns, no relighting or resetting needed. New units also have to meet a federal efficiency minimum that scales with tank size, so the right size for your household matters as much as the type you choose.

- How do I know it's time to replace my water heater?
- Water pooling at the base or rust coming through the hot tap means the tank is failing and needs to be replaced, not repaired. Water that never gets hot, or runs out fast, points to a dying heating element or a burner that can't keep up anymore. A tank that's old and starting to act up is a bad bet to keep repairing, since the tank itself will fail eventually no matter what else is fixed. If yours is showing these signs, replacing it before it fails is the safer bet, especially with winters here cold enough that going without hot water is more than an inconvenience.
- Should I switch to a tankless water heater?
- It depends on what you want out of it. A tankless unit heats water only as you use it, so you get hot water on demand instead of a limited supply that can run out during back to back showers. It also takes up far less space than a tank, which matters in a smaller mechanical closet or basement. The tradeoff is usually upfront cost and sometimes the need to upgrade gas line or venting to match the unit's demand. A contractor can look at your home's gas supply and hot water use and tell you whether tankless makes sense for your household.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and start heating it the moment you turn on a tap. That means no more running out partway through a shower, but it also means the unit has to keep up in real time, so its output has to match your home's peak demand, not just its average use. Venting is different too. Tankless units often need their own dedicated vent sized for the unit, which can mean new venting work during installation rather than reusing what the old tank used. Gas fired tankless units typically need a larger gas line than a standard tank heater, since they draw more fuel to heat water instantly rather than gradually.
