Ten months of heating in Bonner County
Homes here need heat from September through June, ten months a year, and a water heater runs alongside that whole stretch. Winter nights average 22°F, and the tank has to work harder to bring water up to temperature when it starts that cold.
Storms are part of living here. The county logged 338 winter storms and 43 damaging wind events over the last ten years, and in Idaho, 11% of households went at least 24 hours without power in 2024. A gas water heater with a standing pilot will keep making hot water through an outage like that. An electric one will come back on by itself once the power is restored, but not before. Whatever you choose, it has to meet the federal minimum efficiency set for its size, since the standard is set separately for each tank volume rather than as one number for every water heater.

A heat pump water heater would save about $320 a year to run in Idaho compared with an electric water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is age. Once a tank water heater is old enough that it's near the end of its expected life, a repair just delays a replacement you'll need anyway, and a contractor can tell you where yours stands. Rust colored water from the hot tap, a tank that's rusting or bulging on the outside, or water pooling underneath are signs the tank itself is failing, and that's not something to patch. If it's still making hot water but running out faster than it used to, or making popping or rumbling noises, sediment has built up inside and the tank is working harder than it should.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on what's wrong with your current tank. A tankless unit heats water as it's used instead of storing it, so you don't run out of hot water partway through back to back showers or a load of laundry after dishes. It also takes up much less space than a tank. Against that, a tankless unit costs more to install than a like for like tank replacement, and it may need changes to your gas line or electrical setup to run. A contractor can look at your home's setup and tell you what switching would actually involve.
- What changes when you install a tankless water heater?
- The biggest change is that you stop storing hot water and start heating it on demand, which means you won't run out no matter how long the shower runs. The unit itself mounts on a wall and takes up a fraction of the space a tank does. Depending on what's already in place, the installation may call for a larger gas line to feed the higher burner output, a new venting setup, or an electrical circuit for the unit's controls. Most cities and counties require a permit and an inspection for a water heater installation, and a contractor handling the switch will know what your local building office requires.
