Ten months of heavy use, and winters that push the grid
Water heaters in Kellogg work September through June, ten months a year. That is most of the calendar spent recovering hot water for showers and dishes, and the tank cycles on and off far more than it would somewhere with a short winter. That kind of steady demand wears on the heating element or burner assembly and on the thermostat that tells it when to fire.
Winter nights here average 22°F, and the county has logged 189 winter storms over the past ten years, along with 13 damaging wind events. Storms like that knock out power, and across Idaho 11% of households lost power for 24 hours or more in 2024. A gas water heater with a standing pilot will keep running through an outage. One with an electronic ignition or an electric water heater will not come back on its own once the power is out, and you will notice when the water runs cold and stays that way.

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?
- The most common reason is the tank itself has rusted through from the inside and is starting to fail. Once a tank leaks from the bottom, it can't be patched or sealed. The other possibility is a loose drain valve or a fitting that's just dripping, which a contractor can check before condemning the tank. If the leak is coming from the tank itself, the water heater needs to be replaced.
- Why won't the pilot light on my water heater stay lit?
- Usually it's the thermocouple, the small part that senses the pilot flame and tells the gas valve to stay open. When it wears out or sits out of position, the valve reads no flame and shuts the gas off even though the pilot is lit. A weak gas supply or a draft blowing out the flame can cause the same thing. A contractor can test the thermocouple and replace it if that's the cause.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless water heater are repairable. Common issues are a dirty inlet filter, a buildup of scale on the heat exchanger, or a sensor that's failed, and all of these can be serviced without replacing the unit. A contractor will need to look at the specific fault code or symptom to know which part is causing it.
