Kalispell asks a water heater to work most of the year
Homes here need heat from August through June, 11 months a year, and that same cold bears on your water heater. With winter nights averaging 17°F from December through February, the incoming water it has to warm is cold for most of that stretch, and it runs longer to make up the difference.
Power doesn't always stay on through a winter storm. Flathead County has logged 124 winter storms and 69 damaging wind events over the past ten years, and statewide, 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 electronic ignition, gas or electric, won't light again until the power comes back.

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 first. Once a tank water heater is old enough that it needs repairs to keep going, a repair is usually just delaying the next one. Rust-colored water from the hot tap, a tank that's making popping or rumbling sounds, or water pooling around the base are all signs the tank itself is failing rather than a part inside it. A leaking tank cannot be repaired, only replaced. If the unit is old and starting to act up, it's worth having a contractor look at it before it fails on its own, especially with winters here cold enough that going without hot water is more than an inconvenience.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your current heater being bad. Tankless units heat water on demand instead of storing it, so you don't run out of hot water partway through a shower, and they take up much less space than a tank. They also tend to last longer than storage water heaters. What they don't do is deliver hot water instantly at the tap, there's still a wait for it to travel through the pipe. A contractor can look at your gas line, venting, and household hot water use to tell you whether tankless makes sense for your house specifically.
- What changes when you install a tankless water heater?
- The biggest change is that a tankless unit needs more gas flow at once than a tank heater does, since it's heating water as it passes through rather than keeping a tank warm. That often means the gas line has to be resized. Venting is different too, tankless units typically vent through a different type of pipe than a tank water heater uses. Because of this, swapping in a tankless unit is more involved than a straight tank replacement, and a contractor will need to check your gas line and venting before installation to know what work the switch actually requires.
