Sidney asks a lot of a water heater
Winter nights here average 6°F from December through February, and the house needs heat nine months out of the year, September through May. Your water heater runs through all of that alongside the furnace, both mattering most on the coldest nights.
Richland County has seen 18 winter storms and 91 damaging wind events over the past ten years, and 18% of Montana households went at least a full day without power in 2024. A gas water heater with a standing pilot keeps working through an outage. Electric models come back on by themselves once power returns. New units also have to meet a federal efficiency minimum that depends on the tank size and how the household draws hot water, so the right minimum is not the same for every heater.

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?
- Age is the first thing to check. Tank water heaters have a working life, and once yours is old enough that a repair costs nearly as much as a new unit, replacing it makes more sense than patching it again. Rust-colored water, a tank rusting on the outside, or water pooling underneath mean the tank itself is failing, and a tank can't be repaired, only replaced. If it's still making hot water but taking longer to recover or running out faster than it used to, the tank is losing efficiency, and that only gets worse.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on age or a breakdown. A tankless unit heats water as it flows through rather than storing it, so you get hot water on demand and don't run out partway through back to back showers. It needs power to run, so a storm outage leaves you without hot water unless the house has backup power. Storms here have knocked out power for a day or more, and that's worth weighing against a storage tank, which will often keep working through a shorter outage since a standing pilot needs no power at all and even powered tanks recover fast once power is back.
- What changes when you install a tankless water heater?
- The biggest change is space. A tankless unit mounts on a wall instead of sitting on the floor, since there's no tank to store water. It also needs a gas line sized for its higher burner output, or a dedicated electrical circuit if it's an electric model, and venting suited to that unit rather than what the old tank used. Because of that, swapping a tank for a tankless unit is more involved than a straight tank replacement, and a contractor will need to look at the gas line, venting and electrical setup in the house before pricing the job.
