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.

We contacted Zest to provide an estimate for some plumbing work, that we had previously received a quote from another company that didn’t sound right. Wally from Zest was able to find the cause of our plumbing problem after taking the time to do an entire diagnosis (which the other company didn’t do), and saved us thousands of dollars in the process compared to the mis-diagnosis the other company would have cost. Wally was our tech and is extremely professional and very friendly. You could tell he is very experienced. I would not hesitate to use Zest again for any plumbing we need and highly recommend them!

Anthony arrived and did a very good job of explaining what the options were for our service issue. He was very pleasant and social, and best of all he corrected the problem with the least expensive option. I recommend Zest and Anthony to anyone with plumbing needs.

Absolutely phenomenal experience with Zest Plumbing and our technician, Anthony Espinosa! I called at 12:39 PM on a Saturday for an urgent issue—a blocked shower drain that was bubbling sewage. Not only was someone available right away, but the entire issue was completely resolved and Anthony was out the door by 1:59 PM. That’s less than 90 minutes from start to finish on a weekend. Incredible. Anthony was knowledgeable, honest, and incredibly professional. He clearly explained what was going on, took care of the problem efficiently, and didn’t try to upsell me on anything unnecessary. On top of that, he was personable and easy to talk to, which made a stressful situation much more manageable. Zest Plumbing earned my trust today. Fast, transparent, and high-quality service—highly recommend!

I had an outside water bib that I could not get soldered on and called Zest around 8:30 am and they arrived by 10:30 having finished another job. Their workers were pleasant and knew what they were doing. They were able to get the new fitting soldered on in short fashion, I would highly recommend them and would not hesitate to hire them again for any plumbing problems that I may have.
