Navien 30022965A - NaviCirc Recirculation Valve for NPE-A2 Series Tankless Water Heaters

NaviCirc is a simple plumbing device that uses the existing hot and cold water lines to reduce the wait time for hot water at the faucet without the need for a dedicated recirculation return line. Designed for recirculation of domestic hot water in applications where a dedicated return line is not available.

Features

• Designed and optimized for use with Navien NPE-A Series water heater models
• Automatically blocks circulation when the hot water temperature within the valve is about 95 degrees F (35 degrees C)
• Compatible with the Navien HotButton Kit for demand-type recirculation systems
• NaviCirc Kit (30022965A) includes the NaviCirc recirculation valve (PFFW-SXX-001) and two 1/2" x 3/8" flexible hoses and adapters.
• The NaviCirc recirculation valve works best if installed under the furthest accessible fixture away from the water heater. With the NPE-A2 unit’s built-in pump, water circulates through the NaviCirc to preheat the hot water lines, using the cold supply line as the return line back to the water heater.
