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.

Zest always does the best job with the best service! They solve the issue at hand efficiently, and explain the process. We had a leak under our sink that was fixed quickly by Len, and then had some help with maintenance on our water heater and RO water system! I have never had a bad experience with Zest and recommend them 10 times out of 10!

We noticed a damp area in our front yard recently and suspected a water leak. My husband dug up a small section to check the extent of the leak before calling Zest Plumbing. The customer service person told him someone would be out as soon as he finished his current job. Wally arrived within an hour of our call and quickly assessed the situation. He explained the options for replacement and said another coworker would be coming to help out with the job. I am sorry, I forgot the name of this coworker. Both employees were very knowledgeable about line replacement and plumbing issues in general. They were very polite, courteous and honest. They replaced the old, broken up pipe with a new quality pipe line from home to curb within a few hours. Everything was cleaned up and checked out before they left for the day. Thank you so much Wally and your coworker. You both deserve a raise. This was a job well done, in a great time for a great price. We highly recommend Zest Plumbing. They were an 'Answer to a Prayer.'

Called on Zest Plumbing for new hot water heater, water softener and RO system maintenance. Len came out promptly, sized up my needs, provided reasonable options and once contracted, came back a week later for installation and testing. Very pleased with all aspects of his work and my experience with Zest…now my go-to plumbing service contractor.

We had an excellent service experience with Zest Plumbing & drain recently. I called Zest at around 1:00 pm on December 30th to schedule visit to clear a clogged kitchen drain. The friendly representative told me that someone could come out between 2:00 pm and 5:00 pm that same day. At 2:20 I received a text from Zest to tell me that their plumber, Patrick U. was on his way and would arrive in the next 15 - 30 minutes. Patrick arrived as promised, assessed the clogged drain situation, and got to work to get the drain cleared. Patrick was very friendly and pleasant and explained what was likely the problem with our drain. He also told us about some other service options we may want to consider in the future. Patrick quickly resolved the drain clog and cleaned up the work area before he left. I definately recommend Zest Plumbing & Drain and will not hesitate to call them again when the need arises.
