Navien Tankless Water Heaternavien water heater efficiency comparison

In addition to all the usual tankless features like an endless supply of hot water and space savings, the Navien condensing 96% is the most environmentally friendly tankless water heater on the market in the San Diego area.

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

Navien comes 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 non-condensing tankless water heater, be sure to compare output not input!

On the left is a copper heat exchanger that shows erosion after 5 to 10 years depending on hardness of the water and usage. The Navien dual stainless steel heat exchanger are up to 20 times more resistant from erosion than copper heat exchanger.

On the right is a copper heat exchanger that was not serviced. Most tankless brands require yearly flushing maintenance. The Navien stainless steel heat exchanger are more resistant then copper. We at CVB Plumbing recommend every 8 years because nothing is totally maintenance free.
