Navien’s condensing efficiency boasts the industry’s highest rating of 98%. Customers can take advantage of the low annual operating costs and receive the best value and payback, compared with conventional tankless or tank-type water heaters. Navien’s Condensing Tankless offers the highest gallons-per-minute (GPM) when comparing input BTUs.
Navien utilizes dual stainless steel heat exchangers, providing 3.8 to 4.5 times longer life-expectancy and erosion resistance over the copper heat exchangers used in other brands. Navien’s stainless steel heat exchangers operate with relatively low water temperature, minimizing damage from hard water conditions and maintains efficiency levels.
Navien Condensing tankless heaters offer safety and an unlimited amount of hot water supply. Consumers love the endless supply of hot, soothing water!
Navien’s condensing technology uses less gas than conventional water heaters, resulting in less CO2 emissions.
The Eco Pre-mixed Burner dramatically reduces NOx emission levels, making it the lowest emission levels in the industry.
Navien Condensing 98% has become more eco-friendly by dissolving NOx in condensed water to neutralize the alkaline sewage in your house, improving water quality.
Navien primary condensing stainless steel heat exchangers recover extra heat that would be lost in non-condensing tankless water heaters to reduce energy consumption and CO₂ emissions. That keeps exhaust temperatures very low — so low that economical Schedule 40 PVC pipe can be used for venting in almost all applications.
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 the 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 and 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 gas-pressure changes.
Three-phased, Pre-Mixed Burner
Controls flame by pre-mixing optimal ratio of gas and air before combustion, reducing emissions and enhancing heat efficiency.
Leak Detector
Built-in leak detector prevents damage to water heater as well as personal property.
Air Intake Filter
An air intake filter prevents foreign substances, such as dust or insects, from entering the system, freeing the burner from elements that would normally cause unstable combustion or energy inefficiency.
