Tankless Water Heater Service in Arizona

Tankless water heaters use high-powered burners or electric elements to provide endless, on-demand hot water. Unlike traditional water heaters, which continuously heat and store water, tankless systems only heat water when needed, making them more energy-efficient, space-saving, and long-lasting.

At Zest Plumbing & Drain, we specialize in tankless water heater services in Arizona, including installation, repair, maintenance, and replacements. With over 60 years of combined plumbing experience, our technicians ensure your system operates efficiently and reliably.

Whether you are upgrading from a traditional unit or need a quick fix, Zest Plumbing & Drain has the tools and expertise to get the job done right.

The Benefits of a Tankless Water Heater

Homeowners in Arizona have been choosing tankless water heaters over traditional models–and for good reason. Here’s why upgrading to a tankless system could be the right choice for your home:

Endless Hot Water

With a tankless water heater, you’ll never have to worry about running out of hot water. These systems heat water on demand, ensuring a continuous supply whenever and wherever you need it—perfect for long showers, multiple appliances, and busy households.

Energy Efficiency

Tankless systems use less energy than traditional storage tank models. Many models are ENERGY STAR® certified, meaning they meet high-efficiency standards and can help you cut energy costs while reducing your carbon footprint.

Space-Saving Design

Tankless water heaters are compact, wall-mounted units, making them ideal for smaller homes, apartments, or utility closets. Their sleek design frees up space for additional storage or other household needs.

Longer Lifespan

With proper maintenance, a tankless water heater can last 20 years or more, compared to 10-15 years for traditional tank models. This longer lifespan makes it a cost-effective investment, reducing the need for frequent replacements and saving you money on repairs.

Cleaner & Healthier Water

Traditional water heaters store water in a tank, which can lead to rust, sediment buildup, and potential contamination over time. With a tankless system, water is heated fresh on demand, providing cleaner, healthier water for your household.

Increased Home Value

Because of their energy efficiency, long lifespan, and modern design, tankless water heaters are a sought-after feature for homebuyers. Installing one can increase your home’s value and appeal in the real estate market.

On time and seemed to work quickly and efficiently, but really seemed focused on upselling us on other plumbing projects and cost was quite high for 20 minutes of work.

Water heater leaking and put out the pilot light. Cold water showers! I contacted Zelle Plumbing and Drain online during the weekend, booked an appointment, and they came out first thing Monday. He listened to our needs, looked at the old location, recommended a plan, and an hour later he came back with a new one. He had it installed nice and neatly and everything works as expected. Now, hot water showers!
