Long winters and outages that follow storms
Water heaters in Bonners Ferry run September through June, ten months out of the year. Winter nights average 20°F from December through February, and the water coming into the tank is colder too, so the burner or the element runs longer each time to bring it up to temperature. That extra runtime wears on the thermostat and the heating element in an electric tank, and on the burner assembly in a gas one.
Boundary County has logged 338 winter storms and 41 damaging wind events over the past ten years, and in Idaho, 11% of households went at least 24 hours without power in 2024. A gas water heater with a standing pilot will keep running through an outage like that. One with an electronic igniter will not light again until the power is back, and some need someone to reset them. An electric water heater just stops making hot water until the lines are live again.

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?
- The most common cause is the tank itself has rusted through and is failing from the inside. Sediment builds up on the bottom of the tank over years, and once it wears through the lining, water finds a way out. It can also be a loose drain valve or a fitting that has worked itself loose, which a contractor can check before assuming the tank is done. If the leak is coming from the tank body rather than a fitting, the water heater needs to be replaced, not repaired.
- Why won't the pilot light on my water heater stay lit?
- Usually the thermocouple has worn out and can no longer hold the gas valve open. The thermocouple is a small sensor that sits in the pilot flame and tells the gas valve the flame is lit. Once it wears out, the valve shuts the gas off seconds after you let go of it, even though the pilot lit fine. A dirty pilot orifice or a draft blowing the flame out can cause the same thing, so it is worth having someone look at it rather than replacing parts by guess. A standing pilot does not run on electricity, so a power outage is not the cause.
- Can a tankless water heater be repaired?
- Yes, in most cases. Tankless units are built with replaceable parts like the igniter, the flow sensor, and the heat exchanger, and a technician can diagnose which one has failed rather than replacing the whole unit. Mineral buildup inside the heat exchanger is a common issue and can often be flushed out. Whether repair makes sense depends on the age of the unit and what has failed, which is something a contractor can tell you after looking at it.
