NPE-A series
High performance condensing tankless with ComfortFlow Technology. Utilizes existing 1/2" gas pipe lines.
ComfortFlow technology is a proprietary system that incorporates a buffer tank and recirculation pump. The buffer tank will reduce "cold water sandwich" effects commonly found with tankless products and the recirculation pump will minimize the amount of time required for delivery of hot water to fixtures.
