Ten months of heating and winters that cut power
Your water heater works alongside your furnace here, since homes need heat September through June. Winter nights average 16°F from December through February, and that cold reaches the tank and the pipes feeding it.
Bingham County has logged 134 winter storms and 109 damaging wind events over the past ten years, and 11% of Idaho households lost power for at least 24 hours in 2024. A gas water heater with a standing pilot keeps running through an outage. One with electric ignition, or an electric tank, comes back on by itself once power returns.

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 of the time this means the tank itself has failed and is holding water somewhere it should not. Sediment builds up on the bottom of the tank over years, and it can wear through the steel from the inside, or the tank can crack at a weld or fitting. A leak from the bottom is almost never something that gets patched. Once a tank is leaking, it needs to be replaced, so shut off the water and power to it and have a contractor look at it before it does more damage to the floor around it.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a thermocouple that has worn out and no longer senses the flame well enough to keep the gas valve open. A dirty or misaligned pilot orifice can do the same thing, and so can a draft that blows the flame out before the thermocouple heats up. If you have already tried relighting it and it goes out again within a minute or two, the thermocouple is the first thing worth checking. This is a gas appliance, so if you smell gas at any point, leave the house and call your gas company before doing anything else.
- Can a tankless water heater be repaired?
- Yes, most tankless problems are repairs, not replacements. The heat exchanger, the igniter, the flow sensor and the circuit board can all be replaced on their own. Hard water scale inside the heat exchanger is the most common thing that causes a tankless unit to lose output or throw an error code, and that can often be flushed out rather than replaced. A contractor can pull the error code the unit is showing and tell you which part is behind it.
