Ten months of the year, your water heater doesn't get a break
Bozeman needs heat from September through June, ten months of the year. A water heater here is doing steady work almost the whole time, not just through a short winter.
Winter nights average 13°F, and Gallatin County has recorded 124 winter storms and 77 damaging wind events over the past ten years. Power interruptions happen. Most tank water heaters come back on by themselves once power returns, but it is worth having a new install set up right the first time given how much the cold season leans on it. Federal efficiency rules add another wrinkle. The minimum for a storage water heater isn't one number, it is a formula tied to the tank's size and how a household draws hot water, so the right minimum depends on the unit going in.

A heat pump water heater would save about $400 a year to run in Montana compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Look at the age of the tank first. Most storage water heaters have a working life, and once a tank is old, a repair is just a delay before the next one. Rust colored water from the hot side, a tank that's damp or wet around the base, or water that won't get hot anymore are all signs the tank itself is failing rather than just a part in it. If you're calling someone out for the same problem more than once, that's usually the tank telling you it's done. Winters here get cold enough that a weak water heater can fail outright rather than just struggle, so if you're seeing any of these signs, it's worth having someone look at it before a hard freeze rather than after.
- 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 as it flows through rather than storing it, so you get hot water for as long as you run it instead of running out partway through a shower. It takes up much less space than a tank, which matters if yours is tucked in a closet or a tight utility area. Incoming water here runs cold for months at a time, and a tankless unit has to work harder to bring cold water up to temperature, so the flow rate you actually get can be lower than what the unit is rated for. A contractor can tell you what size unit your house would need and whether your gas line or electrical service can support it.
- What changes when you install a tankless water heater?
- You lose the tank, and with it the standby heat loss that comes from keeping a tank of water hot around the clock. Because there's no tank to run out, hot water keeps coming as long as the unit can keep up with the flow, which changes how a household uses hot water rather than rationing it. The unit needs venting suited to its fuel type, and gas models need a gas line sized for the burner rather than for a standard tank. Many homes need electrical or gas line work to accommodate the new unit, so a contractor will need to check what your house already has before installing one.
