In Arizona, a reliable hot water supply is a comfort and part of daily life. From morning showers to running the dishwasher after dinner, your home’s water heater works harder than you might think. Many homeowners are switching to tankless systems because they want a steady supply of hot water and lower energy bills.
At P&L Plumbing, we specialize in helping families make that switch. As a Navien-certified service specialist, we install, repair, and maintain some of the most advanced tankless water heaters available today.
What Is a Tankless (On-Demand) Water Heater?
A tankless water heater, sometimes called an on-demand system, heats water only when needed. Unlike a traditional tank that stores 40 to 80 gallons of water and keeps it hot all day, a tankless unit has no storage tank. Instead, it heats water as it passes through the unit.
Tankless water heaters come in gas and electric versions. In Arizona, gas-powered units are common because they can deliver higher flow rates, which are essential for larger households.
How Tankless Water Heaters Work (Simplified)
When you turn on a hot water tap, the system detects the flow and activates its burner or heating element. Water passes through a heat exchanger, warming up instantly before it reaches your faucet or showerhead. Once you turn the tap off, the system shuts down, saving energy when hot water is not in use.
Navien takes this process a step further with high-efficiency condensing technology. This design captures extra heat from exhaust gases, reducing waste and lowering operating costs. It is one of the reasons homeowners choose Navien over other brands.
Navien is known for building some of the market’s most reliable and efficient tankless water heaters. Their units are compact, energy-smart, and designed with features that make daily life easier. Many models have built-in recirculation systems that speed up hot water delivery, smart controls for remote adjustments, and top-tier efficiency ratings.
When installed by a Navien-trained professional like P&L Plumbing, you can also have peace of mind that your system will meet warranty requirements and be set up for peak performance.

How to Know if Tankless Is Right for Your Home
The right water heater depends on your household’s needs. If your family often uses hot water at the same time, or if you have ever run out of hot water mid-shower, a tankless unit may be the perfect upgrade.
We also consider your home’s layout, existing plumbing, and Arizona’s hard water conditions. During a free evaluation, our team can help you decide if tankless is the right choice and recommend the best Navien model for your setup.
Tankless Maintenance Tips
Like any appliance, tankless water heaters work best when regularly maintained. In hard water areas, an annual descaling helps prevent mineral buildup in the heat exchanger. Filters should also be checked and cleaned as needed.
P&L Plumbing offers Navien-specific maintenance services that protect your warranty and keep your system operating efficiently for years to come.
Tankless Installation Process with P&L Plumbing
Our process begins with an in-home evaluation to determine your hot water needs. We recommend the right Navien model, handle any necessary plumbing or gas line adjustments, and install the unit with precision.
Once the installation is complete, we test the system thoroughly and walk you through the controls and maintenance tips. We also provide ongoing service options so your investment stays in top shape.
Cost and Long-Term Savings
While tankless water heaters cost more upfront than traditional tanks, they often save money in the long run. You will spend less on energy because the system only heats water when you need it. Many homeowners also save on replacement costs, as tankless systems can last 15 to 20 years or more.
In some cases, utility rebates or tax credits are available in Arizona. Our team can help you find out if you qualify.
