Product Details
High efficiency
Condensing technology that offers the highest efficiency (98%), combined with Navien’s innovative tankless features to solve the traditional problems of water heaters.
A faster hot water delivery system
• Eliminates cold water sandwich and issues of minimum flow rate.
• Two models to choose from: NPE-A (Advanced) and NPE-S (Standard), both with high quality output.
• NPE-A features a unique built-in buffer tank and recirculation system reducing time to get hot water and saving water in the process.
• Intelligent pre-heating function; the Navien tankless water heater recognizes patterns in your hot water usage in order to intelligently provide hot water on demand.
Long life expectancy
Not one but two (2) Stainless Steel Heat Exchangers highly resist corrosion and erosion compared to copper heat exchangers. This prolongs the life of your tankless water heater while reducing mineral deposits.
Top honors in energy efficiency
The NPE-Standard has the industry’s highest rated energy efficiency of .98 EF and the NPE -Advanced is not far behind at .97 EF. This is well beyond a standard gas water heater.
Environmentally friendly
The new metal fiber burner was designed to deliver a consistent air/gas mixture improving combustion efficiency. The burner lowers the emission of NOx gases, (≤ 20ppm). It has three stages, from partial to fully lit. Gas combustion in the burner is controlled by a microprocessor for optimal performance. Complies with SCAQMD 1146.2 strict NOx emissions standard.
Less water pressure drop
Features a simple modular water path which minimizes water pressure drop. The modular water path design makes maintenance and service easier to perform.
Flexibility in venting
• Condensing technology uses the energy from the exhaust gases which lowers the temperature of the gases going out of the flue. It can therefore utilize PVC venting, which is not only easier to install, but less expensive.
• 2” PVC, CPVC, Polyprophylene Venting Up To 60’
• 2” venting option allows for a flue to be pulled through an existing vent.
• 3” vents can be used up to 150’ with standard 2” x 3” adapters.
Utilizes existing 1/2″ gas line
Navien NPE is easy to install because they can utilize a home’s ½” gas line and can be easily converted from using natural gas to propane.The negative pressure gas valve and fan with dual venture operation allows for better adaptability to low gas pressure applications. This makes it possible for the NPE to be installed on ½” gas lines up to 24’.
Excellent warranty options
Ask your Washington Energy Services water heater specialist about warranty options for the Navien model you choose.
Brochure
While electric tankless water heaters do exist, it is normally reserved for commercial applications and doesn’t make much sense in a residential home because of the enormous electricity consumption.
Tankless water heaters provides endless hot water, not instant hot water. Your water will arrive at the faucets in approximately the same amount of time as they always have.
