Household Size & Usage:

The size of your water heater should match your household's peak hot water demands.

Assess the number of people in your home and your most intensive hot water usage hour to determine the right capacity.

Tank vs. Tankless:

Decide between traditional or tankless water heaters...

Traditional water heaters store and heat water continuously.

Tankless water heaters heat water on demand and can be more energy-efficient.

Energy Efficiency:

Opt for water heaters with high Energy Factor (EF) ratings to save on utility bills and reduce environmental impact.

Water heaters in Phoenix vary greatly in efficiency, so be sure to consult a professional before installation.

Other Common Water Heater Questions

Who should I call for my water heater?

If you're having trouble with your water heater in Phoenix, call a licensed plumber that specializes in water heater repair and installation. Whether your unit needs maintenance, repair, or full replacement, a professional plumbing company can diagnose the issue and provide safe, code-compliant service.


How much does it cost to replace a hot water heater in Arizona?

In Arizona, the cost to replace a hot water heater typically ranges from $1,400 to $2,500. The final price depends on the size (40 or 50 gallons), type (gas, electric, or tankless), and any upgrades needed to meet current plumbing code. Tankless models are generally more expensive but offer energy efficiency and longer lifespans.


How much does it cost to pay someone to install a hot water heater?

The labor cost alone to install a standard tank water heater in Phoenix usually falls between $500 and $800, depending on complexity. This includes removal of the old unit, installation, and connecting the gas or electric supply. Additional work, like updating venting or expanding a closet, may increase costs.


Do I call a plumber for a water heater?

Yes, a licensed plumber is the right professional to call for anything related to your water heater—whether it's leaking, not heating, or needs replacement. Plumbers are trained to handle all types of water heaters and ensure your system meets Arizona plumbing codes.


What is the life expectancy of a water heater?

Traditional tank water heaters last 8 to 12 years on average. Tankless water heaters can last 15 to 20 years with proper maintenance. Factors like water quality, regular flushing, and correct installation affect how long your unit will last.


How long should a water heater last in Arizona?

In Phoenix, hard water and heat can reduce a water heater’s lifespan. Most tank-style water heaters in Arizona last around 8 to 12 years without maintenance, but annual flushing and water softeners can extend that lifespan significantly.


Why is it so expensive to replace a water heater?

Water heater replacement is costly due to the combination of equipment, labor, and required code upgrades. Plumbers must often update venting, expansion tanks, or shut-off valves to meet safety standards. Also, higher-efficiency models and tankless systems increase overall price.


What is the labor cost to install a 40-gallon hot water heater?

In Phoenix, the labor portion to install a 40-gallon water heater generally runs between $500 and $750. This includes removal of the old unit, installation of the new one, reconnection of plumbing and utility lines, and testing the system for safety.


Does a water softener shorten the life of a water heater?

No, in fact, a water softener can extend the life of your water heater. Hard water causes mineral buildup (scale) that damages heating elements and shortens efficiency. Softened water helps keep your tank and components cleaner, reducing wear and improving performance.


How long should it take to replace a water heater?

Replacing a standard tank water heater typically takes 2 to 4 hours, depending on access and any required updates to plumbing or code. If you’re switching to a tankless system, the process could take a full day due to added gas or venting work.


How many years will a 50-gallon water heater last?

A 50-gallon water heater, if properly maintained, should last 10 to 12 years. In areas like Phoenix with hard water, that lifespan may be shorter unless the unit is flushed annually and installed with a water softener system.


How often should I flush my water heater?

You should flush your water heater at least once per year in Phoenix. Flushing removes sediment buildup, which improves heating efficiency and prolongs the life of the tank. Some homes with very hard water may benefit from flushing every 6 months.


Why is it so expensive to replace a hot water heater?

The expense includes not just the heater itself, but also labor, materials, removal of the old unit, permits, and any updates to meet local code. Newer efficiency standards and added safety features have also increased equipment costs in recent years.


Is it better to flush or drain a water heater?

Flushing is the better option. While draining removes water from the tank, flushing actively agitates and removes sediment, which builds up at the bottom and affects performance. Flushing improves efficiency and helps extend the unit’s life.


Can I flush my water heater myself?

Yes, you can flush your water heater if you’re comfortable with basic plumbing steps. Turn off the power or gas, connect a hose to the drain valve, and run water until clear. However, many Phoenix homeowners prefer to hire a professional plumber for peace of mind and a more thorough cleaning.
