In addition to all the usual tankless features like an endless supply of hot water and space savings, the Navien “Condensing 98%” is the most environmentally friendly tankless water heater on the market.

The Navien tankless hot water heaters eliminate more than 85% of the flue gas wasted by standard tankless water heaters, reducing CO2 emissions by at least 420 lbs less per unit per year. That equates to the photosynthesis work of approximately 14 trees or driving a car 420 miles less per year.

Navien come in BTU ranges (maximum input) from 150,000 to 199,000 and can deliver flow rates up to 11 gallons per minute, making them the best in their class.

Because of its much higher efficiency, Navien heats more water with less BTUs so when comparing with conventional noncondensing tankless water heater, be sure to compare outputs not inputs!

Navien Features:

* PVC venting up to 100 feet
* Exceptional performance: the optional “A” models include a mini-buffer tank eliminating the minimum flow rate requirement and the so-called “cold water sandwich” and a built-in pump offers recirculation capability for hot water to the faucets quicker and water savings
* Precision Technology: with Navien’s patented Gas-Air Ratio Control (GARC), ideal combustion and steady temperatures are continuously monitored and maintained
* Premium materials: dual stainless heat exchangers for much longer life cycles than copper
* One of the best warranties in the business (12 yr./6 yr.)

New Unique Features:

* The only tankless water heater to include built-in “Leak Detection” protecting your property from water damage
* Built-in air filter minimizes dirt and debris from collecting inside the water heater reducing service calls
