NaviCirc valve is an excellent solution for keeping warm water immediately available at the tap and as a mitigation for freezing pipes in Texas. I have to in my house for farthest faucets that aren’t part of the same loop. One star deducted for shutoff noise that repeats whenever recirculating is on.
Valve works great. Shipping took a little longer than expected.
The unit works as suggested it’s been trouble for you since the first day I put it in. I had the temperature at 1:30 but I put it back down to 120 actually put it to 125.
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.
