Eleven months of the year, your water heater doesn't get a break
Homes in Ravalli County need heat from August through June, and your water heater works through all of it. Winter nights averaging 16°F mean the water coming into the tank is colder for longer, so it runs harder to bring it up to temperature.
Power outages are a real risk here. Montana saw 18% of households lose power for 24 hours or more in 2024, and the county has logged 75 winter storms and 41 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep working through an outage. One that depends on electronic ignition will not light until the power is back. Whatever you install, it has to meet the federal minimum efficiency for its size and type, since the standard is set separately for each tank volume and draw pattern rather than as one number for every heater.

- How do I know it's time to replace my water heater?
- Watch for water that doesn't get hot the way it used to, a tank that's making popping or rumbling noises, or rust-colored water or moisture around the base. Once a tank water heater gets old, a repair often just delays the next failure. If the leak is coming from the tank itself rather than a fitting or valve, that tank is done and replacement is the only fix. With winter nights here averaging 16°F, a water heater that fails in the cold months leaves you without hot water right when you need it most.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your old tank failing. A tankless unit heats water only when a tap calls for it instead of storing a tankful, so you get a steady supply as long as the burner or element can keep up with how much you're drawing at once. Homes with heavy hot water use, like several showers running back to back, tend to benefit most. If your current tank still works and just needs a repair, switching isn't something you have to decide right now. A contractor can look at how your household uses hot water and tell you whether tankless makes sense for your house.
- What changes when you install a tankless water heater?
- The biggest change is that there's no tank storing hot water anymore, so the unit fires up only when a tap calls for it. Venting is usually different from what a storage tank used, and the gas line or electrical supply sometimes needs to be upgraded to handle the demand while the unit is running. Space changes too, since tankless units mount on a wall and take up far less room than a tank. A contractor will look at the existing gas line, vent, and electrical setup to know what needs to change in your house.
