Efficient Tankless Water Heaters

Why Navien?

Why choose a Navien Condensing 98% Tankless Water Heater? In a word: Efficiency. You see, Navien utilizes "condensing technology," giving our Water Heaters a 98% efficiency rating. Knocking the competition out of the water, these extremely efficient and eco-friendly units will provide extra savings for you and your family.

Energy Efficiency = Savings

We here at Navien America pride ourselves on manufacturing the most cost-efficient Water Heater available. Our built-in hot water recirculation system recirculates hot water that would otherwise be lost, thus, creating a method that lowers the cost of our customer's water bills each month.

Navien's state-of-the-art technology means our product has a longer life span and lower operating costs than other water heaters, compounding customer savings. This, coupled with Navien's space-saving wall-mount design, which frees up your home's real estate space, only increases the money customers will save. And, Navien's 15-year warranty is the best in the industry-think of it as an added bonus!

Tank, Tankless, and Navien

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.
