Long heating season, cold nights, and power that doesn't always hold in Hamilton
Homes in Ravalli County need heat from August through June, eleven months a year. Your water heater runs alongside that, working through the same long stretch of cold weather, and winter nights here average 16°F from December through February. That cold puts steady demand on the thermostat and heating element in an electric tank, or the burner assembly and thermocouple in a gas one.
The county has also seen 75 winter storms and 41 damaging wind events over the past ten years, and statewide, 18% of households lost power for 24 hours or more in 2024. A gas water heater with a standing pilot will stay lit through an outage, but an electric one will not come back on hot water until power returns and the tank has time to reheat. You will notice it as water that takes longer to heat, or no hot water right after the lights come back on.

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 it means the tank itself has rusted through and is starting to fail. Water heaters corrode from the inside out over the years, and once the tank wall is breached there is no patching it, the tank has to be replaced. A leak at the bottom can also come from the drain valve or a fitting, which a contractor can check before assuming the worst. If it is the tank, shut off the water supply to it and have someone look at it soon, since a full tank holds a lot of water to lose.
- Why won't the pilot light on my water heater stay lit?
- The most common cause is a worn thermocouple, the small part that senses the pilot flame and tells the gas valve it is safe to stay open. When it wears out it can no longer hold that signal, so the gas shuts off and the pilot goes out. A dirty pilot orifice or a draft in the area can also blow it out. A contractor can test the thermocouple and replace it, which usually solves the problem for good.
- Can a tankless water heater be repaired?
- Yes, most tankless water heater problems are repairable. Common issues are a fouled heat exchanger from mineral buildup, a failed igniter, or an error code pointing to a sensor or flow problem. A contractor can flush the unit, replace the specific part causing the fault, and get it back to heating on demand. Full replacement is usually only needed when the heat exchanger itself has failed.
