Butte's cold puts years on a water heater fast
Winter nights here average 14°F from December through February, and homes need heat from August clear through June. That is 11 months where the incoming water runs cold and the tank has to work to bring it up. The thermostat cycles more, the burner or heating element fires more often, and the parts that do that job wear faster than they would somewhere milder.
Power matters too. Silver Bow County has seen 49 winter storms and 17 damaging wind events over the past ten years, and in Montana, 18% of households went at least 24 hours without power in 2024. A gas water heater with a standing pilot keeps running through an outage. One with electric ignition or an electric tank does not, and most units restart on their own once power returns. If yours does not, or the water never gets hot again, that is worth a look.

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 often the tank itself has rusted through and is starting to fail. Sediment builds up in the bottom of the tank over the years, and it traps moisture against the steel until a small hole opens up. A drain valve that isn't seated right or a loose fitting can also leak from the bottom, and those are worth checking first since they can be fixed without replacing anything. If the tank itself is the source, there's no patch for it. It needs to be replaced.
- Why won't the pilot light on my water heater stay lit?
- The usual cause is a worn thermocouple, the small sensor that tells the gas valve a flame is present. When it wears out or sits out of position, it reads no flame even when one is lit, and the valve shuts the gas off. A weak pilot flame or a draft blowing across it can cause the same thing. A contractor can check the thermocouple and replace it if that's the problem.
- Can a tankless water heater be repaired?
- Yes, most problems with a tankless unit can be fixed without replacing it. Mineral buildup on the heat exchanger is a common issue, especially if the unit has never been flushed, and that's a service job rather than a replacement. Igniters, sensors, and fans can also fail on their own and be swapped out. A contractor can look at the error code the unit is showing and tell you what's actually wrong.
