Rockland asks a lot of a water heater

Winter nights here average 16°F from December through February, and the incoming water is just as cold. A water heater in Knox County has to work harder to get that water up to temperature, and it does that work nine months a year, September through May. That is most of the year spent heating cold water in a cold basement or utility closet.

More than half of Maine households lost power for 24 hours or longer in 2024, and Knox County sees storms most winters, an average of more than four a year over the last decade along with a handful of damaging wind events. A gas or propane water heater with a standing pilot keeps making hot water through an outage. One that depends on electronic ignition will not, until the power is back. Either way, the unit installed has to meet the federal minimum efficiency for its size and type, since the standard is set separately depending on how much water the tank holds.

How do I know it's time to replace my water heater?
Look at what the tank is telling you. Rust colored water from the hot tap, rust on the tank itself, or water pooling underneath all mean the tank is failing, and a leaking tank can't be repaired, only replaced. If the unit is old and you're already calling someone out for repairs more than once, that's usually a sign the next fix is temporary. A contractor can look at the age and condition of your unit and tell you whether a repair still makes sense or whether it's time to replace it.
Should I switch to a tankless water heater?
It depends on what you want out of it, not on your water heater being broken. A tankless unit heats water as you use it instead of storing it, so you get a steady supply for as long as you run the tap, which matters if your household runs out of hot water with a tank. It also doesn't sit there keeping a full tank hot around the clock, which is worth something in a place where the heating season runs September through May. The switch usually means changes to the gas line, venting, or electrical supply, so a contractor needs to look at your setup before you decide.
What changes when you install a tankless water heater?
The biggest change is that hot water is made as you use it instead of pulled from a tank that's already heated. That means no running out partway through a shower, but it also means the unit needs enough gas supply or electrical capacity to heat water fast, more than a tank ever needed at once. Venting is different too. Most tankless units need their own dedicated vent, not the one the old tank used, so a contractor needs to check what your gas line, electrical panel, and venting can support before any of that gets changed.
