What Your Neighbors Are Saying About Us

Everything was great. He initially came out and gave me options with no pressure. I decided to get a new toilet since mine was 27 years old. He gave me suggestions of which ones were the best and dis not pressure me to buy one from them. I did pick one based on his suggestions and Consumer Report reviews. He installed it today. He was on time and very nice to deal with.

Dan was very professional even was kind enough to chat with me while he worked to replace two hose bibs and our water main shutoff valve was leaking so he replaced it. Price, quality and professionalism worth every penny. Thank you.

I had Desert water out to my home to do a routine service on my tankless hot water heater. I basically found them through searching and reading up on different companies. So I had no idea how well they would do. I was beyond pleased. everything was off the charts Jose the tech was amazing, knowledgeable, friendly, and just did a great job from start to finish. And their pricing was fair. I’d use them again and rate them five stars plus

Was referred by name from a friend. In my experience they are one of the Absolute Best. From free estimate for replacing water heater to the cost of installation to the employees from installation to front office. 100% my go to for service going forward. They might not be the largest company but by far the better choice and reasonable and competitive prices.

Awesome experience! I highly recommended Desert Water Plumbing. Great customer service. Friendly, polite & professional technicians. They made quick work of getting multiple jobs done. Extremely knowledgeable and provided explanations I could understand. We will definitely call them again.

Dillion came to our house same day that we called. He took care of our broken water heater and the price was more than fair. Dillion was extremely helpful and kind I couldn't be more grateful for the amazing service and the quality work done. When I say reasonably priced I mean every cent of it lol. They are no joke. I have used many plumbers but I'll never go to any but them again.

Excellent responsiveness, Dee called me almost immediately after I submitted my request. Ethan showed up on time and professional and friendly. Went right to work finding the leak. Then came back the same day to do the repair. Thoroughly tested, you can see he was well trained. Highly recommended.

Installed Around Your Schedule, Built for Your Demand

A commercial water heater is not a one-size purchase, and we never treat it like one. Our licensed, bonded, and insured technicians start by assessing your facility’s hot water demand, fuel type, and space constraints, then recommend the unit that fits your operation and budget. We schedule installations and repairs to minimize disruption, working around your business hours whenever possible. And because Peoria’s hard water is especially tough on commercial tanks, we can pair your new unit with water treatment that protects your investment for years longer.

Keep Hot Water Flowing and Operating Costs Down

An aging commercial water heater does not just risk a breakdown, it quietly inflates your utility bills every month. Modern high-efficiency units recover faster, hold temperature under heavy demand, and cost significantly less to run. We make the upgrade straightforward with upfront quotes before any work begins, maintenance plans that extend equipment life, and a satisfaction guarantee on every job. Businesses across Peoria, Glendale, Phoenix, and Scottsdale trust us with their hot water. Call 602-699-4401 to schedule a commercial water heater assessment today.

Frequently Asked Questions

What size commercial water heater does my business need?

It depends on your peak-hour demand, the type of business you run, and your available space and fuel type. We assess your actual usage patterns and recommend a unit with the capacity and recovery rate to keep up, without paying for more than you need.

Should I repair or replace my commercial water heater?

If the unit is relatively young and the fix is minor, repair usually makes sense. If it is near the end of its service life, leaking from the tank, or failing repeatedly, replacement protects you from repeated downtime. We give you an honest recommendation with pricing for both paths.

How fast can you respond if our water heater fails?

We prioritize commercial emergencies because we know hot water downtime can halt your operation. Call us and we will dispatch a licensed technician to your Peoria area business as quickly as possible.

How often should a commercial water heater be serviced?

At minimum once a year, and more often for high-demand operations. Regular flushing and inspection combat the sediment buildup caused by Peoria’s hard water, extend equipment life, and help you avoid surprise failures. We offer maintenance plans that handle it all on schedule.

Are commercial tankless water heaters a good option?

Often, yes. Commercial tankless units supply continuous hot water, save floor space, and reduce energy waste from storing heated water. Whether they fit depends on your demand profile and gas or electric capacity, which we evaluate before recommending one.
