There is no single best water heater for every Arizona home. The right choice depends on your household’s hot-water demand, available space, existing electrical or gas service, efficiency goals, and installation requirements.
For many homeowners in Ahwatukee and the Phoenix East Valley, conventional electric, heat pump, gas tank, and tankless systems are all worth considering. The best water heater installation is the one that matches the equipment to the home rather than simply replacing the old unit with whatever is easiest.
What Are the Main Water Heater Options for Arizona Homes?
Arizona homeowners generally have four main choices when replacing a water heater.
Conventional Electric Tank Water Heaters
Traditional electric tank water heaters remain a common option because they are familiar, widely available, and often relatively straightforward to replace. They may make particular sense when a home already has an electric tank and the installation space is limited.
Their main drawback is efficiency. Conventional electric-resistance systems typically use more electricity than heat pump models.

Heat Pump Water Heaters
Heat pump water heaters also store hot water in a tank, but they use a different heating method. Instead of generating most of their heat with electric-resistance elements, they move heat from the surrounding air into the water.
ENERGY STAR says certified heat pump water heaters can use about 70% less energy than standard electric water heaters. That efficiency advantage can make them particularly appealing in Arizona, where our warm temperatures can support efficient operation when the unit is installed in a suitable location.
Heat pump models do require adequate airflow, clearance, and condensate drainage, so they are not automatically the best fit for every closet or utility area.
Gas Tank Water Heaters
Gas tank water heaters can be a practical choice for homes that already have natural gas service. They offer strong hot-water recovery and can be straightforward replacements when the existing heater is also gas-fired. However, they require proper combustion air and venting, and switching from electric to gas will involve additional installation work.
Tankless Water Heaters
Tankless systems heat water as it is needed instead of maintaining a full storage tank. They can save space and provide long periods of hot water when properly sized. However, installation can be more complicated if the home needs larger gas lines, upgraded electrical capacity, or new venting.
How Do You Choose the Best Water Heater Installation for Your Home?
Start with how your household actually uses hot water. A larger family with simultaneous showers, laundry, and dishwashing may need very different equipment than a one- or two-person household. Tank size, recovery rate, and flow capacity all matter.
The home’s existing infrastructure is equally important. Consider the available fuel source, electrical panel capacity, plumbing layout, venting, and physical space around the water heater.
Efficiency should also be part of the comparison. Replacing an aging conventional electric tank may be an opportunity to consider a heat pump model rather than automatically installing another resistance heater.
For that reason, the best water heater installation needs to account for current needs and the way the replacement will perform over its service life.
What Water Heater Rebates Are Available in Arizona in 2026?
Rebate availability varies by utility and household eligibility. Phoenix-area homeowners should verify current program requirements before buying equipment because incentives can change.
APS Water Heater Rebates
There are no current APS water heater rebates in 2026. The utility company ended its rebate program at the end of last year. You maty find information online, but they’re referring to older efficiency programs. However, things can change. So, it’s worth checking.
SRP Water Heater Rebates
SRP currently offers a residential rebate for qualifying heat pump water heaters. Eligible equipment and installations must meet SRP program requirements, including efficiency and contractor qualifications. Because program rules and deadlines matter, SRP customers should confirm eligibility before selecting a model or scheduling installation.
Arizona HEAR Program
Some income-qualified Arizona households may also be eligible for assistance through the state’s High-Efficiency Electric Home Rebate (HEAR) program.
The program supports qualifying home electrification improvements. Depending on household income and the improvements completed, eligible households may qualify for rebates for multiple energy efficiency installations, including electrical water heaters.
