Taco After Dark
Fall Series 2023 Online & On the Road
Taco After Dark returns with its Fall Series for 2023! Get ready for an energetic, informative, and entertaining program that features practical, real-world solutions to the challenges hydronics professionals face every day.
As part of this Fall Season, we are taking several episodes on the road, bringing the learnin’ and funnin’ to a few places near you. John, Dave, and Rick are visiting several technical schools across the continent and will present live from their training centers. If you are close to these training centers, join us online or stop in. We will also talk with the fabulous instructors at these schools as we do Taco After Dark live from their classrooms with a live audience at the same time.
Following are the dates and locations where we will be presenting live. Please get in touch with Dave Holdorf to inquire about attending in person.
Attendees may register for each session individually, and each program will be recorded and archived for repeated viewing. Each session qualifies you for one PDH credit. YOU MUST ATTEND ONE OF THE THE LIVE WEBINAR SESSIONS (NOT THE RECORDED SESSION) IN ORDER TO RECEIVE YOUR PDH CERTIFICATE. The link to the PDH certificate, along with a link to the recorded webinar session, will be emailed to you approximately 24 hours after the end of each webinar session.
Individual Class Descriptions and Registration links:
Wednesday, Sept. 20
7:00 pm EDT
Part 1: Basic Heat Loss
Every good hydronic system starts with a heat loss. Knowing the BTUH load allows us to accurately size the heating plant, properly size the piping, and – most importantly – select the right circulator for the job without oversizing.
In this fast-paced, fact-filled Taco After Dark session, you’ll learn how to select the correct outdoor design temperature for your area. Once that’s done, you can accurately calculate heat loss due to infiltration as well as window, wall, ceiling, and floor losses. It all starts with knowing the numbers.
Wednesday, Sept. 27
7:00 pm EDT
Part 2: Heat Emitters
Once you know the BTUH heating load, you can now get down to the business of adequately sizing your heat emitters.
We’ll cover fin-tube baseboard, cast-iron and panel-type radiators, radiant floor heating and hydro-air. And whether you’re using a cast iron boiler, a mod-con boiler or an air-to-water heat pump, we’ll share with you how to interpret output and design charts so you can match the heat emitters to the water temperature your heating plant is capable of creating.
Note that this session will be presented live at Conestoga College. Stop in if you are close by!
Wednesday, Oct. 4
7:00 pm EDT
Part 3: Pipe Sizing, Air Control & Pumping Away
In this edition of Taco After Dark, 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.
And speaking of the supply side, this fast-paced, fact-filled hour will go into detail on circulator location, pumping away and what can happen if the wrong circulator is used in the wrong place.
Note that this session will be presented live at PPATEC. Stop in if you are close by!
Wednesday, Oct. 11
7:00 pm EDT
Part 4: Flow, Heat and the Finer Points of Circulator Selection
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.
Wednesday, Oct. 25
7:00 pm EDT
Part 5: ECM Circulator Essentials
ECM stands for Electronically Commuted Motor. And those three little letters are transforming residential hydronics. But do we really know what we need to know about how these remarkable little devices work?
Variable speed technology can do wonders for the modern residential hydronic system, but they’re not magic. They don’t size themselves and they don’t take the thinking out of circulator selection, no matter how many times you press that AUTO button. In this session, we’ll dispel the many myths and common falsehoods about ECM circulators. And we’ll show you the real value of these things will help you create the most efficient system possible for your customers.
Note that this session will be presented live at the New England Institute of Technology. Stop in if you are close by!
Wednesday, Nov. 1
7:00 pm EDT
Part 6: Circulators or Zone Valves
If you were King of Hydronics and you could dictate to the industry how to zone a system, would you insist on one circulator per zone, or would you rule in favor of one circulator and zone valves?
It’s an age-old question, and in this session of Taco After Dark we’ll examine the pros, cons, realities, and myths of both options. And by the time the hour is up, we’ll provide you with the ultimate and definitive answer as to which one is better and why.
Wednesday, Nov. 8
7:00 pm EDT
Part 7: Air-To-Water Heat Pumps and Low Temperature Hydronics
With the movement to “beneficial electrification” well underway, air-to-water heat pumps are becoming a factor in modern residential hydronics.
In this program, we’ll discuss how these things work, what they can (and can’t) do, and how to get into this rapidly growing business. You’ll also learn about the new Taco System M air-to-water heat pump and its unique capabilities.
Wednesday, Nov. 15
7:00 pm EDT
Part 8: Domestic Hot Water Recirculation – Why Sizing and Controls are Beyond Critical
Installing a domestic hot water recirculation system is easy, but installing (and controlling) one correctly requires some know-how.
An oversized DHW recirculation pump without adequate controls is a recipe for disaster. But in this program, we’ll show you the correct way to size and control a DHW recirculation system for all types of water heaters. We’ll pay particular attention to the unique DHW recirculation requirements being set forth by heat pump water heater manufacturers.
Note that this session will be presented live at Johnson College. Stop in if you are close by!
