Nine months of heating season means steady work for a water heater in Jerome County
Homes here need heat from September through May, nine months of the year, and winter nights average 22°F from December through February. A water heater is working the rest of that time too, and one sized right for the household keeps up with that instead of just getting by.
Power doesn't always stay on through a storm. Jerome County has seen 12 winter storms and 18 damaging wind events over the past ten years, and statewide, 11% of households lost power for 24 hours or more in 2024. A gas water heater with a standing pilot keeps working through an outage. One that needs electricity to ignite will not.
Federal rules set a minimum efficiency for storage water heaters, but the number isn't the same for every tank. It's a formula based on rated volume, applied differently depending on how a household draws hot water, so two heaters of the same type can face different minimums. Sizing and installing to meet that standard is part of getting a new one in right.

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 water that won't stay hot, or runs out faster than it used to. Rust colored water, a tank that's rusting or bulging at the seams, or water pooling underneath are all signs the tank itself is failing, not something that can be repaired. A popping or rumbling sound during heating usually means sediment has built up on the bottom of the tank, and once that starts the unit is working harder to do the same job. Most storage tanks are built to last a limited number of years, so if yours is old and starting to show any of these signs, it's worth having a contractor look at it before it fails outright and leaves you without hot water.
- Should I switch to a tankless water heater?
- That depends on what you want out of it, not on any rule that says one type beats the other. A tankless unit heats water as it flows through rather than storing it, so you don't run out of hot water partway through a long shower or back to back loads of laundry. It also takes up much less space than a tank, which matters if you're tight on room in a utility closet or basement. Switching means changing how the water heater is fed gas or power and how it vents, so it's not a swap you make without a contractor looking at what your home already has in place.
- What changes when you install a tankless water heater?
- The biggest change is how the unit connects to your home, not just what it looks like. A tankless heater needs a gas line sized for its burner, or an electrical circuit sized for its output, and neither is usually the same as what a storage tank used. Venting changes too, since a tankless unit vents differently than a tank and often needs new venting run to the outside. Because of these changes, a permit and inspection are required for the installation, and a contractor will need to check your home's gas line, electrical panel and venting before the swap to confirm what needs to change.
