High-Efficiency Heating, A/C & Water Heater Systems

NPE-A Advanced high-efficiency tankless water heater technology for residential and commercial applications. Exclusive ComfortFlow technology with internal buffer tank and recirculation pump maintains a steady stream of heated water to eliminate cold water sandwiches and issues of minimum flow rates.

NPE-S Standard ultra condensing technology without ComfortFlow technology.

• Ultra Condensing Efficiency
• Two Stainless Steel Heat Exchangers - Provides longer life expectancy as they are highly resistant to corrosion and erosion compared to copper heat exchangers.
• Low NOx Emissions (≤ 20ppm) - New metal fiber burner is designed to deliver a consistent air/gas mixture improving combustion efficiency.
• 2 in. PVC, CPVC, Polyprophylene Venting Up To 60 ft.
• Utilizes Existing 1/2 in. Gas Line - The negative pressure gas valve and fan with dual venturi operation allows for better adaptability to low gas pressure applications.
• Field Convertable: NPE models allow for easy convertibility from NG to LP.
• Less Water Pressure Drop - Simple modular for water path minimizes water pressure drop.
• Front Panel Command Center - with self-diagnostics.
