What a new water heater needs to handle here
Nogales winters aren't harsh, but nights average 33°F from December through February, and homes here run their heat six months a year, November through April. A water heater in an unconditioned garage or utility space feels those cold nights, and the incoming water it has to heat is colder too.
Power isn't always steady. Across Arizona, 7% of households lost power for 24 hours or more in 2024, and Santa Cruz County has seen 17 winter storms and 53 damaging wind events over the past ten years. Most gas water heaters with a standing pilot keep working through an outage. Most electric ones, and gas units with electronic ignition, come back on by themselves once the power returns. Either way, it's worth knowing which kind you have.
Any new storage water heater installed today has to meet the federal minimum efficiency for its type and size. That minimum isn't one number. It's set by a formula based on the tank's rated volume, and it's applied differently across four different draw patterns, so two tanks of the same type in different sizes can face different minimums.

A heat pump water heater would save about $250 a year to run in Arizona compared with an electric water heater.

- How do I know it's time to replace my water heater?
- Age is the first thing to check, and most storage water heaters wear out well before anyone expects. If yours is up there in years and you're seeing rust colored water, water pooling around the base, or it's not keeping up with hot water like it used to, those are signs the tank is failing rather than something a repair will fix. A leak from the tank itself, not a fitting or valve, means replacement, since the tank can't be patched. If the unit is old and needs a repair that costs a real share of what a new one would, most homeowners are better off replacing it before it fails outright and leaves them without hot water.
- Should I switch to a tankless water heater?
- It depends on what you want out of it, not on your tank failing. A tankless unit heats water as it flows through instead of storing it, so you don't run out of hot water during back to back showers or a full house of guests. It also takes up less space than a tank. The tradeoff is that a tankless unit needs a strong enough gas line or electrical circuit to heat water on demand, so switching from a tank usually means some work beyond just swapping the unit. A contractor can look at your gas line, venting, and electrical setup and tell you what switching would actually involve in your house.
- What changes when you install a tankless water heater?
- The biggest change is that hot water no longer runs out. A tank holds a fixed amount and once it's used up you wait for it to reheat, but a tankless unit heats water as you use it, so a long shower doesn't run the house out of hot water for the next person. Because there's no tank, you also lose the standby heat loss that comes from keeping a tank full of hot water around the clock. On the installation side, a tankless unit often needs a larger gas line or dedicated electrical circuit than the water heater it's replacing, along with different venting, so the swap usually involves more than just disconnecting the old tank and connecting the new unit.
