Navien’s official entry into the commercial boiler market
We caught up with Brian Fenske, Director of Commercial Sales to learn about the Navien NFB-C commercial boiler while at AHR Expo.
First let us acknowledge that no official press info has been released with delivery date, technical specifications etc at this time. As soon as we receive that information from Navien, we will be the first to share here and on our social media.
Now for all the details
Here’s what we do know about the Navien NFB-C boilers:
There will be two models available, the NFB-C-301 and 399. Each number corresponding to the Btu input rating. The model name [NFB-C] translates to Naven Firetube Boiler – Commercial. Each boiler will have at its core Navien’s unique in-house design and manufactured stainless steel heat exchanger. For more info on their new firetube click here.
These boilers will have the usual negative pressure gas system and as stated in the video, can be adjoined in cascade [up to 4 units] with common venting. Brian Fenske does a great job explaining all this and more in our video from AHR Expo, please watch below.

Taco announced their newest pump at AHR Expo, the Taco 0018e ECM circulator with Bluetooth connectivity. John Barba, Taco’s head trainer, shows us how the Taco 0018e pump works when connected to the accompanying mobile app.
Press info direct from Taco
“The circulator features Bluetooth communication to a mobile app. This provides real time control, diagnostics and reporting, such as installation history, power consumption, performance and runtime. The installer can select between multiple constant speed, proportional pressure, and constant pressure modes as well as activeADAPT™, Taco’s self-adjusting proportional pressure mode.”
You can read the entire press release here on hydronicshub.com
Will the 0018e be the go-to pump for installers?
For the first time here in North America we are looking at a hydronic system pump that can show us what’s happening inside the system. That’s not only cool but, ultimately its one of the most useful employments of modern technology.
With four modes of operation this pump can be optimized for almost any residential hyrdronic system. Operating modes include infinitely variable fixed speed to fine tune any zone, constant pressure for zone valve applications, proportional pressure for panel radiators with thermostatic radiator valves (TRV) or the self-adjusting activeADAPT™ auto mode.
The 0018e, however, is not suitable for chilled water or potable water applications.
Operation modes explained: Taco 0018e Pump
The Taco 0018e is factory programmed for MAX SPEED setting out of the box, initial connection via the mobile app is required to adjust the settings.
Fixed Speed mode:
Fixed speed mode (Zone Circ) allows the installer to fine tune the circulator flow rate to precisely match design load conditions. It is infinitely variable between MIN/MAX settings. This setting is ideal for zoning with circulators.
Constant Pressure mode:
In constant pressure mode (ZV), the circulator maintains a constant pressure differential (Δp-c) in the system as heating load increases or decreases. Selections options are Medium or High. This mode is best option for zoning with zone valves.
Proportional Pressure mode:
In proportional pressure mode (TRV), the circulator maintains a proportional pressure differential (Δp-v) in the system as heating load increases or decreases. Flow will change in relationship to the change in pressure differential. Selections options are Medium or High. This is the best option for panel radiators with thermostatic radiator valves (TRV).

RIDGID® Press-In Branch Connector Tool Kit for 3/4-Inch Branches Eliminates the Need to Weld Ideal for chilled water, compressed air, industrial gas and low-pressure steam systems https://www.youtube.com/watch?v=9MuUwpBFQ4Q&t=23s Press Release: ELYRIA, OHIO – January 14, 2019 – Quickly make 3⁄4-inch branch connections on black steel pipe with the new RIDGID® Press-In Branch Connector Tool Kit being Read more
RIDGID® Press-In Branch Connector Tool Kit for 3/4-Inch Branches Eliminates the Need to Weld
Ideal for chilled water, compressed air, industrial gas and low-pressure steam systems
Press Release:
ELYRIA, OHIO – January 14, 2019 – Quickly make 3⁄4-inch branch connections on black steel pipe with the new RIDGID® Press-In Branch Connector Tool Kit being introduced at AHR Expo today. Significantly faster when compared to traditional welding, it is ideal for adding gauges or 3⁄4-inch pipe in chilled water, compressed air, industrial gas and low-pressure steam system applications.
Plumbers, pipe fabricators and maintenance professionals working on 11⁄2-inch to 6-inch black steel pipe will not only save time but also eliminate fire risk and avoid the additional expense of a fire safety watch.
The Connector Tool Kit includes an expander that fits all RIDGID standard press tools, including the RP 340, RP 330, RP 320 and CT-400, and works with Viega Press-In Branch Adapter Fittings. The kit also contains fitting positioning guides, an arbor shaft assembly, drill guide, and vacuum adapters.
The hole saw arbor attaches to standard drills, includes an M27 hole saw, and is designed to prevent the saw from penetrating both sides of the pipe; while the vacuum adapters allow for connection to standard size vacuum hoses to help reduce steel chips falling into the pipe while making the branch. Both the positioning and drill guides ensure proper placement against the pipe.
“The RIDGID Press-In Branch Connector Tool Kit takes our standard press tools up a notch. This accessory kit not only reduces complexity, but more importantly, it speeds up the process when creating branches,” said Rob Trefz, RIDGID Director of Business Development and Marketing. “Particularly in industrial gas settings, when you can eliminate flames and a fire watch, it provides significant project cost savings.”
The Connector Tool Kit comes with the RIDGID Full Lifetime Warranty. Contact your local distributor, visit RIDGID.com, or call toll-free: 1-800-769-7743 to learn more.

We get our first in-depth look at the new Navien NFC
We stopped at Navien’s booth at the AHR Expo to look under the hood of the new Navien NFC combi-boiler using Navien’s own firetube heat exchanger.
Take a look at the video to see some details and specs, one thing that surprised me right away was the included accessories. For contractors looking for high amounts of hot water production, a low head loss heat exchanger for easier piping on the hydronic side and additional features like remote connectivity it looks like the NFC is worth checking into. You can find more details and specifications on Navien’s website or here in our new product listings on Hydronics Hub.
All the bells & combi boiler whistles
The new Navien NFC combi boiler models come with a patented in-house designed and manufactured heat exchanger, Low Profile Burner for ease of service, advanced controls offering intuitive user navigation, a built-in DHW module (pump, flat plate heat exchanger, 3-way valve, mixing valve, water adjustment valve and auto water fill valve), common venting capability up to 8 units, cascading capability up to 16 units, and built-in hardware to connect up to 3 zone pumps without a need for additional external controllers.

This wall will be radiantly heated in addition to the heated floor. The space below the window will have a freestanding tub, to the right will be a tile shower. I think its safe to say the master bathroom will be very comfortable for the owners!
