Anchorage water heaters work all year, with no break
Your water heater has no season off here. Homes in Anchorage need heat 12 months a year, and the same is true of your hot water, since incoming water runs cold through a winter where nights average 10°F from December through February. The burner or heating element has to work harder to bring that water up to temperature, and it does that work every day of the year, not just in the cold months.
That steady demand wears on the parts that do the heating first. A gas unit's igniter or thermocouple sees more cycles over a year of constant use. An electric unit's heating element works harder to keep up. When one of these starts to fail, you notice hot water that runs out faster than it used to, or water that never gets as hot as it should.

Repair makes sense when an element, thermostat or gas valve has failed.
Replacement makes sense when the tank itself is leaking.
- Why is my water heater leaking from the bottom?
- Most often the tank itself has rusted through from the inside and is starting to fail. Water can also drip from the bottom if the drain valve is loose or a fitting above the tank is leaking and running down the side. A cracked tank cannot be repaired, so a contractor will need to check where the water is actually coming from before you know if you need a new water heater or just a valve or fitting fixed. With winter nights here averaging 10°F, a leaking water heater that stops working is worth getting looked at quickly.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn out thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out, it shuts the gas off even though the flame is lit. A dirty pilot orifice or a draft blowing the flame out can cause the same problem. A contractor can test the thermocouple and replace it if that is the issue.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Common issues include a buildup of mineral scale on the heat exchanger, a failed igniter, or an error code pointing to a sensor or the venting. A contractor can run the diagnostics built into the unit to find out which part is causing the trouble and repair it rather than replace the whole unit.
