Ten months of hot water demand in Pocatello
Water heaters here work September through June, ten months a year. On winter nights averaging 18°F, the incoming water is colder, so the burner or the elements run longer to bring a tank up to temperature. That extra runtime wears on the thermostat and the heating element in an electric tank, or the burner assembly in a gas one.
Bannock County sees its share of winter storms and wind, and the state as a whole saw 11% of households lose power for a day or more in 2024. When the power drops, an electric water heater stops heating until it's back, and a tank already working hard through a cold winter has less to give when it comes back online. If your water heater is taking longer to recover between uses or isn't getting hot at all, that's often where to start looking.

A new water heater would cut about $60 a year off hot water for a typical Idaho home.

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 corroded through and is failing from the inside. Sediment builds up over years and eats at the metal until it starts to weep, and once a tank leaks like this it needs to be replaced, not patched. 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 the leak is coming from underneath the tank itself and not a connection, plan on a new water heater.
- Why won't the pilot light on my water heater stay lit?
- The thermocouple is the usual cause. It is the small sensor that sits in the pilot flame and tells the gas valve the pilot is lit, and once it wears out it can't hold that signal, so the valve shuts the gas back off. A dirty or clogged pilot orifice can cause the same thing. Either one is a repair a licensed contractor can make without replacing the whole unit.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit are repairable. Common issues are a scaled-up heat exchanger, a failed igniter, or an error code pointing to a bad sensor, and a contractor can diagnose which one it is from the code the unit displays. Tankless units need descaling on a regular schedule, and skipping that is what shortens their life. A unit only needs full replacement when the heat exchanger itself has cracked or failed.
