Rinnai Tankless Water Heater Advantages

Here’s how Rinnai has earned the trust of our customers:

  • Incredible energy efficiency. Some models achieve up to 96% AFUE efficiency, and many are EnergyStar certified.
  • Years of trouble-free performance. When installed by trained professionals like ATEL Air, you can expect reliable hot water for years to come.
  • Range of options. Condensing models for more comfort and energy efficiency, and non-condensing models for lower cost. Multiple sizes are also available for different levels of demand.
  • Wifi ready. Make adjustments from your smartphone in your home or on the road.
  • No need to wait for hot water when you open the tap. With the recirculating feature, a small amount of water is kept hot and ready to go.
  • Easy installation. Some models can be installed on standard ½” gas lines. There are also many venting options.
  • Increases your home’s value. Most homes are going to tankless water heaters because the technology is just better. If you sell your home, your tankless system can attract buyers.
  • Great warranty coverage. While the exact number of years depends on the model you choose, you’ll find Rinnai’s coverage provides great peace of mind.

I want to thank you and your team for providing me with excellent, quality service! Not only did Dwayne answer all my questions, but he took the time to explain things to me and is very knowledgeable. The installation guys were friendly, organized and did a clean professional job. Awesome!

Professional Installation is the Only Way to Get Great Results

In the past 15 years, ATEL Air has not removed a single on demand/tankless water heater from our customers’ homes.

If you’ve heard of a friend or someone online who didn’t like their Rinnai tankless water heater, ask these important questions:

  1. Was it the right model for the home and amount of water needed?
  2. Was it properly installed by a technician who was manufacturer-trained in all the important details?

Our technicians are fully trained with years of experience in real-world installations.
