Taco After Dark, Part 1 – Basic Heat Loss
In the midst of lockdowns, quarantines, and social distancing, Taco Comfort Solutions would like to help you use this time to sharpen your skills. Together we are offering Taco’s full-day field training class to you one hour at a time.
In Part 1, join Taco’s John Barba, Rick Mayo, and Dave Holdorf as they 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 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

Taco After Dark, Part 2: Heat Emitters
Join Taco Comfort Solutions for Part 2 of Taco After Dark as we discuss Heat Emitters. In Part 1 we learned about simple heat loss calculations. In Part 2 we’ll now use that information to size various heat emitters, including fin-tube baseboard, cast iron radiators, and radiant floor heating. We’ll also look at boiler selection and learn the difference between a boiler’s DOE output and its net I-B-R/AHRI output. You won’t want to miss this fast-paced, fact-filled hour of non-stop hydronics.

Taco After Dark, Part 3: Pipe Sizing, Air Control and Pumping Away
Join Taco Comfort Solutions for Part 3 of Taco After Dark. Join us as we build on lessons learned in Parts 1 and 2 and discuss how to size boiler piping based on load, how and why different kinds of air separators work, and just what all the fuss is about with circulator location and pumping away.
You’ll also learn one of the cornerstones of our shared business: The Universal Hydronics Formula. You’ll learn how to use this formula to size pipe, size circulators and troubleshoot. It’s kind of handy.You won’t want to miss this fast-paced, fact-filled hour of non-stop hydronics.
Wed, May 5
Taco After Dark, Part 4: Figuring Flow & Head, and the Finer Points of Circulator Selection
Join Taco Comfort Solutions for Part 4 of our ongoing series, Taco After Dark. In our first three segments, we learned about heat loss, heat emitters, and boiler selection, all building blocks for the next phase of the program. In Part 4, we’ll use all that knowledge to take the next step, which is to actually determine flow and head loss and then use that information to make the best circulator selection possible.
You’ll also learn where pump performance curves come from, as well as the importance of system curves and how those two little items will determine the overall performance of your hydronics systems. Make sure to sign up! You won’t want to miss this fast-paced, fact-filled hour of wall-to-wall hydronics

Taco After Dark, Part 5: Zone Pumps, Zone Valves & The Great Debate
Since the first amphibians crawled out of the slime, this debate has been raging: Which is better, zone valves or zone pumps?
In Part 5 of Taco After Dark, 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 taking a look at the wild and wonderful world of variable speed circulators. You won’t want to miss this fast-paced, fact-filled hour of wall-to-wall hydronics!

Taco After Dark, Part 6 – The TRUTH About Variable Speed Circulators; What They Do and Don’t Do
Variable speed circulators are not “magic,” and they certainly don’t “do the thinking for you.” The industry is rife with misconceptions and misinformation about residential variable speed circulators, and it’s important for the plumbing and heating professional to know what they’re using and why.
In Part 6 of Taco After Dark, presented by Taco Comfort Solutions, Taco’s John Barba, Rick Mayo, and Dave Holdorf will dissect today’s variable speed ECM circulators, tell you what they do and – more importantly – what they don’t do. These little devices have the potential to greatly enhance the overall efficiency of any residential hydronic heating system, but they do need to be installed and programmed properly. In this session, you’ll learn what’s real, and what isn’t.
Wed, May 26
Taco After Dark, Part 7 – The REAL Value of Variable Speed Circulators
Variable speed circulators aren’t magic, they don’t size themselves and the don’t “do the thinking for you.” We learned all that in Taco After Dark, Part 6. But if all that’s true – and it is – what is the real value of these little devices?
In Part 7 of Taco After Dark – presented by Taco Comfort Solutions, Taco’s Rick Mayo, Dave Holdorf, and John Barba will continue the discussion on ECM and variable speed technology, and show you how variable-speed can benefit your residential hydronic systems…if applied and programmed properly. We’ll discuss the different types of variable speed circulators and show you which operating modes make the most sense for which applications, and how the right pump can enhance the overall efficiency of any hydronic system. You won’t want to miss the fast-paced, fact-filled event!

Taco After Dark, Part 8 – Mod-Con Boilers, Buffer Tanks and Zoning
The right approach to piping a multi-zone system with a mod-con boiler can make all the difference. Do it effectively and you have a system that purrs like a kitten and provides your customer with years of optimal efficiency, performance, and comfort. Do it wrong, however, and you may have just planted a time bomb in your customers’ basement — and an inefficient one at that.
In Part 8 of Taco After Dark, presented by Taco Comfort Solutions, you’ll learn the finer points of piping a mod-con boiler, including when to use a primary-secondary “moose-antler” piping arrangement, when to use a hydraulic separator and when to use a buffer tank (you’ll also learn how to size one!). Join us Wednesday night for another fast-paced, fact-filled episode of Taco After Dark.
Wed, June 9
Taco After Dark, Part 9 – Mixing Valves, Multi-Temp, Multi-Load Systems and Understanding Indirects
Even if you use a mod-con boiler, there will be instances where you will want to use some sort of mixing device. In Part 9 of Taco After Dark, presented by Taco Comfort Solutions, the boys at Taco will share with you the finer points of tempering valves and motorized mixing valves, including how they work, how they add pressure drop to the system, and how the proper application can help improve overall system efficiency.
The fast-paced, fact-filled, and fun session will also discuss indirect water heaters, what the ratings and specifications mean, and where they come from. You’ll also learn how to select the proper pipe size and circulator for the application, how to figure recovery, and how to enhance the performance of a potentially undersized tank.

Taco After Dark, Part 10 – Domestic Hot Water Recirculation Done Right
Did you know the average family of four wastes more than 14,000 gallons of water annually just waiting for the hot water to arrive?
Domestic hot water recirculation is the next great frontier in home comfort. But just like everything else we’ve discussed in this series, it takes a professional to do it right. In this program, we’ll discuss the finer points of DHW recirculation every professional needs to know. You’ll learn the right way to properly size your DHW circulator (bigger is NOT better). And you’ll learn the pros and cons of various control strategies (smart and simple CAN coexist).
This fast-paced, fact-filled event will show you how easy it can be to do DHW recirculation in a professional way, and how you can provide your customers with convenient, safe, and efficient hot water delivery.
