Yuma doesn't ask much of a water heater, but the grid sometimes does
Winters here are mild. December through February, nights average 43°F, and a water heater in Yuma is not fighting the cold the way one does further north. That means the tank spends most of the year just keeping up with normal household use, not straining against the weather.
The bigger question is what happens when the power goes out. Arizona saw 7% of households lose power for 24 hours or more in 2024, and the county has logged 61 damaging wind events over the past ten years. A gas water heater with a standing pilot will keep working through an outage. One with an electric ignition or an electric tank will not come back on until power does, though most units restart on their own once it's restored. Whatever you install, it also has to meet the federal minimum efficiency rule, which is set by the tank's size and how the household draws hot water, so the number that applies to your home depends on the size you need.

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?
- A water heater near the end of its life usually tells you before it fails outright. Look for rust colored water, a tank that's rusting on the outside, water pooling underneath it, or a tank that makes rumbling or popping sounds as it heats. If it's struggling to keep up with hot water for your household, that's a sign the tank is wearing out inside. If a contractor finds the tank itself is leaking, that means replacement, since a leaking tank can't be patched.
- Should I switch to a tankless water heater?
- It depends on what you want out of your hot water and what your home can support. A tankless unit heats water on demand instead of storing it, so you don't run out partway through back to back showers, and it takes up less space than a tank. It also usually needs a larger gas line or a dedicated electrical circuit than a storage tank does, so switching often 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 gets heated as you use it instead of sitting ready in a tank. That means no standby heat loss from a tank of water staying warm all day, but it also means the unit needs enough gas supply or electrical capacity to heat water fast, on demand. Venting is different too, since tankless units often vent through a wall or use a different type of pipe than a tank does. Because of these differences, installing one usually means more than a straight swap, and a contractor can tell you what your home's gas line, electrical panel, and venting can support.
