Tankless Water Heaters in Gilbert, AZ

At AZ Hot Water Now, we’ve spent decades helping Valley homeowners enjoy reliable, efficient hot water. More and more families in Gilbert and surrounding communities are making the switch to tankless water heaters and hybrid water heaters…and it’s easy to see why. Our desert climate, with hot summers and mild winters, makes energy efficiency more important than ever. And with tankless technology, you can enjoy endless hot water on demand, lower energy bills, and more space in your home without sacrificing comfort.

How Tankless Water Heaters Work

Unlike traditional water heaters that store hot water in a tank, tankless systems heat water instantly as it passes through a coil. The moment you turn on the faucet or start the shower, cold water flows through the unit and is heated immediately. That means no more waiting for a tank to refill or reheat…just continuous hot water whenever you need it.

Tankless systems come in both gas and electric versions, and each has its advantages. We’ll guide you through the options to ensure you get the right system for your home and lifestyle.

Installation Considerations

Every home is different, which is why our team carefully sizes and installs tankless water heaters based on your household needs. One of the most important factors is gallons per minute (GPM) — the measure of how much hot water your home uses at peak times. A family in Chandler with multiple bathrooms will need a higher GPM unit than a smaller household in Florence.

Gas tankless models require proper venting, which we handle during installation to ensure safety and efficiency. Electric tankless units, on the other hand, are often easier to retrofit into existing spaces. No matter which option you choose, we’ll walk you through every step and make sure your system is perfectly matched to your home.

Maintenance for Hard Water Conditions

Arizona’s hard water presents unique challenges for all water heating systems, and tankless units are no exception. Without proper maintenance, minerals like calcium and lime can build up in the heat exchanger, reducing efficiency and shortening the system’s lifespan.

That’s why we recommend annual descaling for tankless water heaters. Our team uses professional tools to flush the system and keep it operating at peak performance. This small maintenance step pays off by preventing costly repairs and ensuring your unit delivers endless hot water for years to come.

Gas vs. Electric

Tankless Water Heaters
Choosing between gas and electric tankless models depends on your household needs and home setup:

  • Gas Tankless Water Heaters: Provide higher flow rates, making them ideal for larger families or homes with multiple simultaneous water demands. They’re efficient and reliable but require professional venting.
  • Electric Tankless Water Heaters: Easier to install in many existing homes and better suited for smaller households or specific applications like guest houses or workshops.

Our licensed plumbers will evaluate your home’s water usage and energy setup, then recommend the best option for your situation.

Hybrid Water Heaters

A Smart Alternative
For some homes in Gilbert, a hybrid water heater is an excellent option. Hybrids combine traditional tank storage with energy-efficient heat pump technology. They’re especially effective in moderate climates like ours, where they can draw in ambient air to help heat water more efficiently. Hybrid systems offer:

  • Lower operating costs compared to standard tanks
  • Faster recovery times than traditional models
  • Flexible hybrid Water heater installation options for households that aren’t ready to go fully tankless

We install and service hybrid water heaters throughout the Valley, giving you another great way to balance efficiency and performance.
