Ketchikan asks for hot water and steady power, all year
Water heaters here run year round, same as the furnace. There's no season where the tank gets a break. Winter nights averaging 33°F mean the incoming water is cold enough that the tank has to work for its keep every single day, not just a few months.
Power is the other piece. Statewide, 21 percent of Alaska households lost power for 24 hours or more in 2024, and the borough has seen 10 damaging wind events and 3 winter storms over the past ten years. A gas or propane water heater with a standing pilot keeps making hot water through an outage. One that depends on an electronic igniter or powered controls does not, until the power comes back. Worth deciding on before the next storm, not during it.
Any new tank also has to clear the federal minimum efficiency for its size and type. That minimum isn't one number. It's set by a formula tied to the tank's rated volume, and it's applied differently depending on how the household draws hot water, so two tanks that look alike on paper can face different minimums.

- How do I know it's time to replace my water heater?
- Age is the first thing to check. Most tank water heaters last 12 years or so, and once you're past that, a repair is just delaying the next failure. Watch for water around the base of the tank, since a leak there usually means the tank itself has failed and it's not fixable. Rusty or metallic-tasting hot water, a tank that makes popping or rumbling noises, or hot water that runs out faster than it used to are also signs the tank is on its way out.
- Should I switch to a tankless water heater?
- It depends on what you want from your hot water and what your home can support. A tankless unit heats water on demand instead of storing it, so you don't run out partway through a shower the way you can with a tank. It also takes up less space and tends to last longer than a storage tank. The tradeoff is that installation often means new venting and gas or electric supply lines sized for the unit, which a contractor will need to check against your home's setup.
- What changes when you install a tankless water heater?
- The biggest change is that hot water gets heated as you use it instead of sitting ready in a tank. That means no more running out of hot water partway through back to back showers or a full load of laundry. It also means the unit needs a gas or electric supply sized for heating water instantly, and its own venting, which is usually different from what a tank used. A contractor will look at your home's existing gas line, electrical panel, and venting to see what needs to change before the new unit goes in.
