A water heater here works year round, with no season off
Kotzebue winter nights average -6°F from December through February, and homes here need heat all twelve months. A water heater installed in this kind of cold works every day of the year, with no stretch of mild weather to ease the load on it.
Power is worth planning around too. In Alaska, 21% of households went at least 24 hours without power in 2024, and the borough has logged 18 winter storms and 8 damaging wind events over the past ten years. On the efficiency side, the federal minimum for a storage water heater is not one number. It is set by the tank's size and how a household draws hot water, so the minimum that applies to a new unit depends on the size chosen for the home.

- How do I know it's time to replace my water heater?
- Watch for water that never gets as hot as it used to, rust-colored water, or rust around the tank itself. A tank that's rusting from the inside will eventually leak, and once it does, it needs to be replaced right away. Age matters too. Storage tanks have a working life, so if yours is old and starting to act up, it's worth having a contractor look at it before it fails on a night when it's 6 below outside. Also listen for rumbling or popping sounds, which usually mean sediment has built up on the bottom of the tank, making it work harder and wear out faster.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on whether one is simply better than the other. A tankless unit heats water as it flows through rather than storing it, so you don't run out of hot water partway through a shower or a load of dishes. It also has no tank to rust out or leak. But it needs a gas line, venting, and electrical supply sized correctly for your house, and that's a bigger installation than swapping one tank for another. A contractor can look at your home's setup and tell you whether the switch makes sense for you.
- What changes when you install a tankless water heater?
- The biggest change is that hot water becomes available on demand instead of coming from a stored tank, so you're not limited by tank size when several people need hot water back to back. That means the venting, gas line, and sometimes the electrical circuit have to be sized for the unit, which is more involved than replacing a tank in the same spot. Where the old tank sat, you'll likely get back some floor space too, since a tankless unit mounts on the wall. A contractor who installs these regularly can walk through what your specific house needs before the work starts.
