Nephi asks a lot of a water heater
Winter nights here average 20°F from December through February, and homes in Juab County need heat eight months a year, October through May. A water heater works harder over a season like that, pulling in cold groundwater and holding a tank of hot water through long, cold nights.
The county has seen 72 winter storms and 48 damaging wind events over the past ten years, and across Utah about 7% of households lost power for a full day or more in 2024. A gas water heater with a standing pilot keeps working through an outage. One that relies on electronic ignition will not light until the power is back. Whichever type goes in, it has to meet the federal minimum efficiency for its size, which is set separately for each tank volume rather than as one number for every heater.

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

- How do I know it's time to replace my water heater?
- Look at the age first. Water heaters have a limited lifespan, and one that's old and starting to act up is usually better replaced than repaired. Rust-colored water, a tank that's rusting on the outside, or water pooling underneath are signs the tank itself is failing, and that can't be fixed. Rumbling or popping sounds mean sediment has built up on the bottom, and that shortens what's left of its life. A water heater that runs out of hot water faster than it used to is also telling you the tank is wearing out.
- 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 you use it instead of storing it, so you get a steady supply and don't run out partway through a shower. It takes different venting and gas line work than a tank does, and sometimes an electrical upgrade too, so the installation itself is bigger than swapping one tank for another. A contractor can look at your home's setup and tell you what changing over would actually involve.
- What changes when you install a tankless water heater?
- The unit itself is small and mounts on a wall instead of taking up floor space. It needs its own venting, sized for that specific unit, which is different from what a tank uses. Gas-fired tankless units often need a larger gas line than the one feeding a tank, because they draw more gas in short bursts to heat water on demand. Some installations also call for an upgraded electrical connection. A contractor can check your home's gas line, venting, and electrical setup to know what's needed for yours.
