Stillwater County puts your water heater to work most of the year
Homes here need heat from September through June, ten months where the water coming into your tank starts out cold. That means longer run times to bring it up to temperature, and on winter nights averaging 15°F, the tank is working hardest when you need it most. That steady demand wears on the heating element or burner assembly over time.
Power loss is the other thing working against you. Montana households went at least 24 hours without power in 18% of cases in 2024, and the county has logged 160 winter storms and 112 damaging wind events over the past ten years. Most water heaters come back on by themselves once power is restored, but a gas unit with a standing pilot will need that pilot relit by hand. If yours is electric and stays cold after the lights come back on, the thermostat or element may have failed, not just the power.

A new water heater would cut about $60 a year off hot water for a typical Montana 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 rusted through, and that means it needs to be replaced, not repaired. Water heaters corrode from the inside over the years, and once the tank wall gives way, no patch or part fixes it. The leak can also come from the drain valve or a fitting on top that is dripping down the side and pooling at the bottom, so it is worth drying everything off and watching where the water actually starts. If it is coming from underneath the tank itself, shut off the water and power or gas to it and have a contractor look at it before it fails completely.
- Why won't the pilot light on my water heater stay lit?
- The most common reason is a worn thermocouple, the small sensor that tells the gas valve the pilot is burning. When it wears out, it shuts the gas off even though the flame is lit. A dirty pilot tube or a draft blowing the flame out can cause the same thing. If it keeps going out after you relight it a few times, that points to the thermocouple or the gas valve rather than something you can fix by relighting it again.
- 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 venting are the parts that most often cause trouble, and each can be serviced on its own. Mineral buildup in the heat exchanger is common and is cleared by flushing the unit rather than replacing it. A contractor can tell you which part is failing once they see the error code the unit is showing.
