A water heater here works all year, with no summer to rest in
Winter nights in Delta Junction average -10°F from December through February, and homes here need heat all 12 months. A water heater in that cold has no season to let up. It holds a full tank hot around the clock, every month of the year, not just the coldest ones.
Power is part of the picture too. Across Alaska, 21% of households went at least 24 hours without power in 2024, and this area has logged 12 damaging wind events over the past ten years. Most storage water heaters come back on by themselves once power returns, gas or electric, so a new one installed here should be one that recovers on its own after an outage. And because the federal minimum efficiency for a storage tank is set by its size and how a household draws hot water, the right minimum for your home depends on the tank you actually need, not one number that applies to all of them.

- How do I know it's time to replace my water heater?
- The clearest sign is age. Tank water heaters wear out from the inside, and once a unit is old a repair is often just delaying a bigger failure. Rust colored water from the hot side, a tank that's rusting on the outside, or water pooling underneath all mean the tank itself is failing, and a tank that's failing gets replaced, not patched. If it's still running but struggling to keep up, that's worth a look too, especially with how cold the incoming water line gets here in winter, since a unit near the end of its life has less capacity to spare.
- Should I switch to a tankless water heater?
- It depends on what you're trying to fix. A tankless unit heats water on demand instead of storing it, so you don't run out during back to back showers, and it takes up far less space than a tank. It's not an automatic upgrade for every home. Tankless units need enough gas supply or electrical capacity to fire at full output, and with incoming water running cold all winter here, the unit has to work harder to hit the same temperature rise. A contractor can look at the gas line or panel and the household's hot water use and say whether it makes sense for this house.
- What changes when you install a tankless water heater?
- The biggest change is that the house stops storing hot water and starts heating it as it flows through the unit. That means no standby heat loss from a tank sitting full of hot water all day, but it also means the unit needs a gas line or electrical circuit strong enough to deliver a burst of power the moment a faucet opens. Venting changes too, since a tankless unit vents differently than a tank does, and that often means new venting has to be run. Recirculation lines, if the house has them, may need to be reconnected differently as well. A contractor will know exactly what the switch requires for this house.
