Taco Tuesday Training Webinar Series

Designing and Controlling Residential Domestic Hot Water Recirculation Systems - 1 PDH

Presented by John Barba, Dave Holdorf, and Jason Kockx

Just how important is proper design for domestic hot water recirculation systems? Well, it’s very important, but not for the reasons you might think. While an undersized recirculation pump can be problematic, an oversized one can be downright catastrophic.

In this fast-paced, fact-filled hour, you’ll learn how to properly size a domestic hot water recirculation pump and how to control its operation to make sure your customers have hot water when they want it.

ECM Circulators Out of the Basement (Part 1) – 1 PDH

Presented by John Barba, Dave Holdorf, and Jason Kockx

In this one-hour webinar, we are leaving the residential (sort-of) basement and dive into the larger world of ECM circulators. Sometimes you just need more (ok, a lot more) than what the 0015e3 can do. The VR circulators have performances up to 65 foot of head and out to 320 gallons per minute, with the programmable buttons and the interface, the options are endless between a simple fixed speed operation to variable speed operation for use in those larger systems like snowmelt and those much, much bigger homes and projects. This session is going to focus on the different modes and the associated piping systems the work with.

VR Circulators – Controls and Programming (Part 2) – 1 PDH

Presented by John Barba, Dave Holdorf, and Jason Kockx

Continuing from the last Residentially focused Taco Tuesday when we took a look at ECM circulators out of the basement, this Taco Tuesday session will focus on wiring, controlling and advanced programming.

The days of just putting a relay on a circulation ends with this built-in controller. Advance variable speed functions as well as parallel pump modes with be explored to make this line of circulators fulfill all of your large scale projects.

Heat Pump Water Heaters and Domestic Hot Water Recirculation - 1 PDH

Presented by John Barba, Dave Holdorf, and Jason Kockx

Heat Pump water heaters are gaining popularity throughout North America. But there remains a challenge in how to best integrate domestic hot water recirculation with these units. Heat Pump water heater manufacturers are split on the topic, but saving water is just as important as saving electricity.

In this fast-paced, fact-filled hour, we’ll discuss the various DHW recirculation options and review which ones work best with Heat Pump water heaters and which ones should be avoided at all costs.

Zone Valves vs Zone Circulators - 1 PDH

Presented by John Barba, Dave Holdorf, and Jason Kockx

Since the first amphibians crawled out of the slime, this debate has been raging: Which is better, zone valves or zone pumps? In this Taco Tuesday webinar, we'll examine that question by looking at the pros and cons of each. Whichever way you choose, you'll learn how to make sure you have the right circulator (or circulators) for the job, and we'll start looking at the wild and wonderful world of variable speed and how they can optimize your system, no matter how you choose to zone. You won't want to miss this fast-paced, fact-filled hour of wall-to-wall hydronics!

Flow, Head and the Finer Points of Circulator Selection  - 1 PDH

Presented by John Barba, Dave Holdorf, and Jason Kockx

The next step in building a great hydronic system is understanding the interrelationship between BUTH, flow, pressure loss (known as head loss) and pipe sizing. All of those ingredients go into proper circulator selection.

In this class, you’ll learn why there’s no such thing as one circulator for all applications, and how our industry actually has a chronic circulator oversizing problem. And we’ll also start the discussion on variable speed ECM circulators and why there’s no such thing as a circulator that sizes itself.

Pipe Sizing, Air Control and Pumping Away  - 1 PDH

Presented by John Barba, Dave Holdorf, and Jason Kockx

In this edition of Taco Tuesday, you’ll learn how to properly size your boiler header and distribution piping based on the BTUH load. You’ll also learn the difference between an air scoop and an air eliminator, how both work and why they work best on the supply side.

Speaking of the supply side, this fast-paced, fact-filled hour will discuss circulator location, pumping away, and what can happen if the wrong circulator is used in the wrong place.

Heat Loss for Hydronics - 1 PDH

Presented by John Barba, Dave Holdorf, and Jason Kockx

Join Taco as we discuss the importance of a heat loss analysis, what information you'll need, and the very simple math behind it all. A heat loss is important for everything from a simple boiler replacement to a major remodel or new construction. This fast-paced, hour-long overview will give you the basics for simple heat loss as well as the resources to conduct your own heat loss calculations.

Topics will include:

• Calculating infiltration
• Heat loss through windows and doors
• R-value vs. U-value
• Ceiling and floor loads
• What the totals mean
