Navien Condensing Water Heaters supply unlimited hot water at a steady temperature whenever you need it and for as long as you need it. Navien water heaters create a more comfortable living environment.

Ultra Condensing Efficiency

The industry's highest energy efficiency at 98% means the lowest annual operating costs and the best payback compared with conventional tankless or tank-type water heaters.

Saves, on average, more than $160 per year over conventional tankless gas water heaters.
Shortest payback of any tankless water heater on the market.
Best gallons per minute performance when comparing input BTU.

Eco-Navien Technology

Ultra efficient burner uses less gas resulting resulting in a substantial CO2 and NOx emmissions reductions.
Less NOx and CO2 means less acid rain and less greenhouse gases minimizing ozone layer depletion.

Extended Lifecycle

Navien's dual stainless steel heat exchangers are up to 20 times more resistant than copper heat exchangers to erosion and condensation damage.

Easy Venting

The higher efficiency of Navien water heaters result in lower exhaust temperatures that allow the use of PVC or other plastic venting materials.
Plastic venting offers significant cost savings and easier installations.
3" PVC venting runs to 100" with 6 elbows.

Advanced Technology

Enhanced Safety with Dual Microprocessors

Navien's two microprocessors offer better control and safer operation by continuously cross monitoring each other's performance to assure proper operation at all times.
These two microprocessors not only control the burner for ideal combustion but also maintain a steady hot water temperature.

Optimal and Stable Combustion with APS and GPS

APS (Air Pressure Sensor) maximizes combustion efficiency by sensing and controlling the air required for optimal combustion even in high wind locations or in installations with long vent runs.
GPS (Gas Pressure Sensor) offers stable combustion by sensing gas pressure and controlling the fan speed to maintain optimal combustion even under a wide range of changing gas pressure.

Leak Detector

Built-in leak detector prevents damage to the water heater and to personal property caused by a water leak.
