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.

Lochinvar’s new Cogeneration Heat & Power System

Lochinvar and EC POWER, the top European producer of residential and commercial combined heat and power products, announced the launch of XRGI25, one of the most cutting-edge cogeneration products to ever be released in North America. Lochinvar originally announced the strategic partnership with EC POWER in April 2018.

Using an internal combustion natural gas engine, Micro CHP (< 50 kW/hr), is designed to be an efficient and easy-to-install system intended for light commercial use. Using natural gas as a fuel, a commercial facility with a cogeneration system like the XRGI25 can produce both energy-efficient heat for domestic hot water and electricity to reduce energy consumption from external power sources.

More information from Lochinvar about the Cogeneration Heat & Power System is available here.

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 in our Product Spotlight

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.

Taco 0018e Operation Modes graphicFixed Speed mode:

Fixed Speed ModeFixed 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:

Constant Pressure ModeIn 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:

Proportional Pressure ModeIn 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).

A totally new venture for the pump making giant: Air to Water Heat Pump System

Taco’s new prototype heat pump was front and center. Imagine our surprise when first learning of Taco’s venture into the home heating appliance market through partnership with GlenDimplex.

Taco has been a leader in the hydronic system component and pump manufacturing industry since 1920. To our knowledge this is a first for the US pump giant. According to Wikipedia, GlenDimplex is an Irish based consumer electrical goods firm headquartered in Dublin, Ireland. The company is privately held. Has manufacturing and development centers in the Republic of Ireland, the United Kingdom, China and many other locations around the world.

We had no previous knowledge of this system prior to the show. Our interview with Taco Canada’s Mike Miller is below. All the technical details we know are included in the video.

Our thoughts on the new Heat Pump system

First, I’m told Taco had the new heat pump on display in their booth as sort of a “soft” reveal for their affiliated reps and interested vendors. This seems about right. Next, even the deepest Google searches and requests for official technical info from our contacts at Taco have come up short. Nonetheless it looks like a very exciting prospect for contractors, especially plumbing contractors not equipped to install refrigeration piping. In short, this is a hydronic system making it very attractive to a much larger crowd of potential installers.

AHR Expo 2019

First, we realize you may have missed attending AHR this year. However you can get a recap of the show from The Hub’s John Mesenbrink.

John’s latest blog touches on the city of Atlanta, some things that impressed him most [and some things that were a little less than impressive]. To clarify, please don’t get us started on our Uber/Lyft experiences while staying in the city. Check out John’s blog here.

Overall, if you found this and John’s blog useful please let us know! You can send us an email or post a comment below.

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.
