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
