navicirc

We recently purchased a 3-story duplex, and each unit had its own tank water heater, leading us to believe that the plumbing was separate for each unit. The heater on the 3rd floor of the upper unit (ours) was due for replacement, so we had our plumber replace it with a tankless Navien...

I have an NPE-210A2 and installed a Navicirc at the farthest faucet in the house from the water heater. I set it to external recirculation, moved the internal switch to external, and set NO below to use the internal pump, and set the recirc mode to "always on." Looking at the history on the...

Hello! Couple of months ago I had the NPE-210A2 installed with NaviCirc Thermostatic Valve at the farthest fixture. For the first few weeks the system was working fine. There were times the valve would make a 'woop' sound which acted somewhat as a confirmation that it was working. Recently the...

I've had a Navien NPE-240A2 installed since May with a NaviCirc at the end of my house. The unit does NOT have a T off the cold water line to the recirc inlet. The internal valve is set to EXT, the control panel is set to EXT with NO external pump. The recirc feature works as expected...

I have a NPE-240S2 and recently had a Grundhos pump installed with two navicircs in the house. One side of the house works fine. The other side of the house and/or the Kitchen sink don't seem to circulate. When I tried the NAvicirc in the kitchen, I don't see any check valves. There is a 3rd...

Hello, I just had my Navien NPE-240A (EDIT: It's actually an NPE-240A2) and NaviCirc installed today. First time tankless user. I was reviewing the manual and installation after they left, and I don't think they have the NaviCirc hooked up properly, and I want to confirm before I call them back...

Hello everybody, I thought I’d share with you all how my hot water recirculation project is going. For the water heater I have a Navien-240A. For accessories I got the Hotbutton kit and two Navicirc thermal bypass valves. I set DIP switch #2 “ON” for external recirculation. I set Perameter...

Is there a way to use Navien navicirc with the hot button? The website isn't clear on this. My customer isn't tech savvy and won't agree to the wifi app.

Recently had a navien tankless NPE 240a installed. Also got two navicirc one for each bathroom and set up external recirculation through the cold water line. At the end of a recirculation cycle (can hear the water flow + clicks for the navicircs) one of the navicircs (the one in the master)...

Greetings. New to this forum but I saw other Navien posts on here so thought I could get some help. Here's the story: Just moved into a house and the previous homeowners had a Navien NPE 240A installed. I wanted to get it checked out (so that someone could explain to me how it worked...

A laurel, and hearty hello! This is my first post here on this forum. I hope it isn't premature, as I am still learning. I have done quite a bit of searching here, and have found answers to many of my questions. But I wanted to get some more feedback to further my knowledge. I just had a Navien...
