Why You’ll Love Your Navien Tankless Water Heater

Navien tankless water heater

Naviens boast some truly unique advantages:

  • Energy Efficiency. Models range from 95% to 97% AFUE efficiency. That’s as efficient as possible with today’s technology.
  • Qualifies for energy efficiency rebates. If there’s a government or gas supplier rebate, Naviens will qualify.
  • Comfort Control. Set the timer to put the unit in ‘’standby” when you’re at home, and enjoy instant hot water as soon as you turn on the tap.
  • Easier and less expensive to install. Naviens use standard ½” gas lines, so there’s no need to convert your existing supply lines.
  • Multiple sizes and flow rates. You can right-size your water heater for your current and future needs.
  • Industry’s best heat exchangers. Navien not only has two heat exchangers for faster heat transfer, they’re both made of stainless steel, not copper. They resist corrosion and water scale much better.
  • Space saving design. Navien tankless water heaters mount to a wall, and save floor space in your utility area.
  • Industry leading warranty coverage. The tank is covered for 10 years, and the heat exchangers for up to 15.
  • Condensing technology. Innovative design reclaims almost all of the “waste” heat and uses it to help pre-heat water, instead of losing it up the vent.
  • Easier venting. Because so much heat is recycled, smaller venting pipes can be used.

The Secret to Good Results: Professional Installation

If you’ve heard that tankless water heaters are “fussy” or “not reliable”, ask these important questions:

  1. Was it sized properly for the home and level of demand?
  2. Was it installed by an expert technician who was trained by the manufacturer?

With ATEL Air, you’ll always be able to answer “yes”!

I have had ATEL Air work on multiple projects and every time I am so pleased with the people they send to my home. Even when a unit that was in my home that they did not put in they serviced it and made things right. I give this company an A plus!
