Water heaters here work through winters that do not let up
Delta Junction needs heat in the house and hot water at the tap every month of the year. With winter nights averaging -10°F from December through February, incoming water runs colder for longer, so the water heater spends more of the day recovering a tank of hot water. That extra work falls on the heating element or the burner assembly, and it shows up first as water that used to feel hot running lukewarm, or a tank that takes longer to catch up between showers.
Power matters too. Across Alaska, 21 percent of households lost power for 24 hours or more in 2024, and this area has logged a winter storm and a dozen damaging wind events over the past ten years. When the power drops, an electric water heater stops heating until it is back, and a gas unit with an electronic igniter will not relight on its own. Either way, someone has to check it once power returns.

- Why is my water heater leaking from the bottom?
- The most common reason is that the tank itself has corroded through and is failing. Sediment builds up on the bottom of the tank over years, and it traps moisture against the steel until it rusts a hole in it. A leak can also come from a loose drain valve or a fitting that has failed, so a contractor will check those before saying the tank is done. Once the tank itself is leaking, it needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- Most of the time this means the thermocouple has worn out and can no longer sense that the flame is lit, so the gas valve shuts off the pilot to be safe. A dirty or bent pilot tube can cause the same problem by keeping the flame from reaching the thermocouple. Wind or a draft near the water heater can also blow the pilot out on relight, which happens more with vents or nearby doors that let in outside air during the cold months here. A contractor can test the thermocouple and clean or adjust the pilot assembly to fix it.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Mineral buildup on the heat exchanger is the most common issue, and it's cleared with a descaling flush rather than replacing parts. Igniters, flow sensors, and circuit boards can also fail on their own and be swapped out individually. A contractor can run the unit's diagnostics to find out which part is causing the trouble.
