Tankless Water Heater Installation in Phoenix, AZ

Tankless Water Heater Installation
Since 1979, Tankless Pros AZ has been helping homeowners in Phoenix and surrounding cities upgrade their water heating systems with reliable, high-performance solutions. If you are considering a new water heater, a tankless water heater installation offers one of the most efficient, dependable, and long-lasting options available today. Our expert team proudly serves Phoenix, Scottsdale, Sun City, Peoria, Glendale, Paradise Valley, Goodyear, Surprise, Litchfield Park, and many nearby Arizona communities.
We specialize in Navien tankless water heaters, a trusted brand known for efficiency, durability, and cutting-edge features designed to meet the hot water needs of Arizona households.
Why Choose a Tankless Water Heater Installation?
Traditional water heaters store 40–80 gallons of water at a time and keep it hot around the clock, even when you are not using it. This constant reheating wastes energy and shortens the lifespan of the tank. With a tankless water heater, water is heated on demand as it flows through the system. The result is an endless supply of hot water, lower utility bills, and a system that can last up to 25 years with proper care.
Tankless water heater installation is more affordable than ever, and rebates or tax credits may be available, making this upgrade both cost-effective and environmentally responsible.
Unlimited Hot Water On Demand
One of the main reasons homeowners make the switch is the comfort of never running out of hot water. Whether your household has multiple showers running in the morning or back-to-back laundry and dishwashing loads, a tankless system ensures consistent performance. Cold water enters the unit when you turn on the faucet and is flash-heated as it passes through. Hot water flows continuously until the tap is turned off, eliminating the frustration of lukewarm showers.
Instant Hot Water Recirculation
Many homeowners are familiar with the waste that occurs while waiting for hot water to reach a faucet. With Navien’s Navi-Circ hot water recirculation technology, hot water is instantly available when and where you need it. This feature saves water, prevents unnecessary delays, and reduces overall utility costs. No more gallons wasted down the drain as you wait for the water to heat.

Lower Energy Bills and Greater Efficiency
Heating large amounts of stored water is one of the biggest contributors to high energy bills. Tank-style units must work continuously to maintain water temperature, which means energy is consumed even when hot water is not being used. By contrast, tankless water heaters only heat water on demand. Many homeowners save up to 50% on their energy bills, depending on usage. This reduction in energy use also means a lower environmental impact. Navien tankless units are rated between 0.95 EF and 0.97 EF, exceeding Energy Star standards and qualifying for a federal 30% tax credit.
Enhanced Safety and Reliable Temperature Control
Safety is a top concern for families, and tankless water heaters provide consistent water temperatures that minimize the risk of scalding. With precise digital controls, homeowners can set and maintain comfortable water temperatures without fluctuation. This makes gas tankless water heater installation a smart choice for families with children, elderly residents, or anyone who values peace of mind.
Compact Design Saves Space
Tankless units are about the size of carry-on luggage and can be wall-mounted indoors or outdoors, making them a space-saving solution compared to bulky storage tanks. This flexibility allows you to free up space in your garage, utility closet, or mechanical room while still enjoying powerful hot water performance.
Advanced Technology and Smart Features
Modern tankless systems come equipped with advanced features that make them user-friendly and convenient. Many models offer Wi-Fi connectivity, enabling you to control your system remotely from a smartphone or tablet. Adjusting temperatures, monitoring usage, or receiving maintenance alerts is simple and convenient.
Built to Last in Arizona Homes
Arizona water is known for its high mineral content, which can wear down standard water heaters over time. Navien units use dual stainless steel heat exchangers that resist corrosion and scale buildup, making them more durable than copper-based systems. With proper maintenance, homeowners can expect 25+ years of reliable service. Navien also offers one of the best warranties in the industry, including 15 years on the heat exchanger and five years on other parts.
Professional Tankless Water Heater Installation
Installing a tankless water heater is not a do-it-yourself project. It requires expert knowledge of plumbing, gas lines, venting, and electrical systems. At Tankless Pros AZ, our technicians are Navien-certified, ensuring every installation meets manufacturer standards and local building codes. We provide full-service installation, from assessing your home’s water demand to selecting the right unit, completing the installation, and providing training on how to operate your new system.
Our team also offers long-term maintenance solutions to keep your water heater running at peak efficiency. Regular flushing, inspections, and filter changes extend the life of your system and protect your investment.
Affordable Options and Financing
We understand that upgrading to a tankless water heater is a major investment. That is why we provide upfront written quotes, transparent pricing, and flexible options to fit your budget. In many cases, we can provide a quote over the phone. For more complex projects, we schedule an on-site evaluation to ensure accurate recommendations.
In addition, we help customers explore tax credits, rebates, and financing options that make tankless water heater installation more affordable.
