Cold ground water and long outages both take a toll
Fairbanks needs heat from August through June, 11 months a year, and that keeps a water heater working nearly the whole time too. Winter nights averaging -10°F mean the water coming into the tank is colder than most heaters see elsewhere, so the burner or element runs longer to bring it up to temperature. That extra runtime wears on those parts faster.
Power matters here too. Statewide, 21% of households went at least 24 hours without power in 2024, and the area has recorded 8 winter storms over the past ten years. Most water heaters come back on by themselves once power returns, but a standing pilot that will not stay lit, or a heater that stays cold after the lights come back on, is worth checking before the next storm.

- Why is my water heater leaking from the bottom?
- Most of the time this means the tank itself has rusted through and is failing, not something that can be patched. Water heater tanks corrode from the inside over years, and once the steel gives way the leak will not stop or seal itself. It can also be a loose drain valve or a fitting at the bottom, which a contractor can check before assuming the tank is done. If it is the tank, replacement is the only real fix.
- Why won't the pilot light on my water heater stay lit?
- A pilot that won't stay lit is usually a sign the thermocouple has worn out. That's the small sensor that sits in the pilot flame and tells the gas valve it's safe to keep the gas flowing. Once it wears out or sits out of position, the valve shuts the gas off as a safety measure, even though the flame was fine. It's a simple part to replace and not something to keep relighting on your own if it keeps going out.
- Can a tankless water heater be repaired?
- Yes, most tankless problems are repairable. Common issues are a clogged inlet filter, a buildup of scale on the heat exchanger, or a sensor that's failing, and a contractor can service any of these without replacing the unit. Some tankless models also give an error code on a display, which tells a contractor what's wrong before they even open it up. Full replacement is rarely the first step with these systems.
