Kanab asks a lot of a water heater
Winter nights here average 23°F from December through February, and homes need heat from October through May, eight months of the year. That's most of the year that incoming water starts out cold, and a new water heater has to make up that difference every time someone runs a tap.
The federal minimum efficiency for storage water heaters isn't a single number. It's a formula based on the tank's rated volume, applied separately across four draw patterns, so two tanks of different sizes are held to different standards even though they look alike. A contractor sizing your replacement has to work against that formula, not a flat rule.

A heat pump water heater would save about $230 a year to run in Utah compared with an electric water heater.

- How do I know it's time to replace my water heater?
- The clearest sign is water that no longer gets hot the way it used to, or runs out fast when it never did before. Rust colored water, a tank that's rusting or damp at the base, or a popping and rumbling sound when it heats are all signs the tank itself is failing rather than just needing a repair. Most storage tanks last a limited number of years, and once one starts leaking from the tank itself, that's not something to patch. If your heater is old and any of these show up, especially with winter here running October through May, it's worth having a contractor look at it before it fails on a cold morning.
- Should I switch to a tankless water heater?
- It depends on what you want from your hot water and what your home can support, not on whether tank heaters are outdated, because they aren't. A tankless unit heats water as it flows rather than storing it, so you don't run out partway through a long shower, but it also means the unit needs enough gas supply or electrical capacity to heat water on demand, which your current setup may or may not have. If your tank works fine and just needs replacing like for like, that's a reasonable choice too. A contractor can tell you whether your home's gas line or electrical panel can support a tankless unit and what that switch would involve.
- What changes when you install a tankless water heater?
- The biggest change is that hot water is made on demand instead of stored, so there's no tank sitting full and ready, and no limit to how long the hot water lasts as long as the flow rate stays within what the unit can handle. This usually means new venting, since tankless units vent differently than a tank does, and it can mean upgrading the gas line or adding electrical capacity depending on the model. Some homes also need a different water line setup to get water to the unit properly. A contractor can walk through what your specific house would need before the swap.
