Because Navien's stainless-steel condensing heat exchanger is able to recover the
condensation that would otherwise be lost, the small amount of exhaust that is released
from Navien Water Heaters is cool to the touch (about 85˚F-130˚F), allowing the
use of PVC venting materials. The use of PVC offers significant cost savings and
simplifies installation.

- Unfortunately, old-fashioned tank heaters, as well as conventional tankless water
heaters, emit harmful Nitrogen (NOx) and Carbon dioxide(CO2 ) directly into the
air at a whopping 245˚F-450˚F! These harmful emissions damage both us and the environment
in which we live.

Navien Condensing 98% Tankless Water Heater's Benefits Also Include:
An Endless Supply of Hot Water: Navien's Condensing 98% is an on-demand
water heater; thus, the unit is activated the second you turn on the faucet, supplying
you with instant hot water. Conventional tank-type water heaters eventually run
out of water, but because Navien's units only supply water when needed, running
out of hot water is never an issue.
Built-In Circulation Pump & Buffer Tank: These two parts save precious
water by recirculating water that would otherwise be lost. Together, they also eliminate
the minimum-flow requirement as well as the dreaded "cold-water sandwich."
Automatic Water Leak Detection: Special software detects leaks,
preventing damage to the water heater—or worse, a home or business!
In-Take Air Filter: Navien's filter minimizes dirt and debris from
collecting inside, reducing service calls.
Eco-Friendly: The Condensing 98% has the lowest levels of Nox and
CO2 emissions, a savings equal to about 420 pounds of carbon-dioxide reduction.
Easy Installation: PVC venting is super economical, convenient and
easy for professional installers to hook up.
