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

Sizing, Piping & Pumping for Indirect Water Heaters - 1 PDH
Presented by John Barba, Dave Holdorf, and Jason Kockx
There’s more to sizing and piping an indirect than meets the eye. In this fast-paced, fact-filled hour, you’ll learn how to read the specs of an indirect, how boiler size impacts recovery, why proper pipe sizing and circulator selection are important, and how to make an indirect think it’s bigger than it is.

Finer Points of Mod-Con Boiler Piping – Hydraulic Separators, Buffer Tanks and Making Sure You Get the Circulator Right - 1 PDH
Presented by John Barba, Dave Holdorf, and Jason Kockx
On your next Mod-Con boiler installation, should you use a hydraulic separator, a buffer tank, or just a pair of closely spaced tees? In this webinar, you’ll learn how to install each of them correctly and, more importantly, when, where and why you should choose one over the other two.
Additionally, you’ll learn how to make sure you have the right boiler circulator, and the dangers of over-pumping.

Deep Dive: 3-Speed and 3-Setting Circs 0015 to the 0034eplus – 1 PDH
Presented by John Barba, Dave Holdorf, and Jason Kockx
Do you use 3-speed circulators? Do you run into them on installations and wonder why they are always set for HI? Would a lower speed/setting work? In this Taco Tuesday webinar, we are going to take a deep dive into the world of 3-speed AC circulators and their ECM equivalents. Don’t call these ECM circulators 3-speeds, these 3-setting circulators are similar but better in so many ways.

Deep Dive – New Zoning Controls – 1 PDH
Presented by John Barba, Dave Holdorf, and Jason Kockx
You’ve heard us debate the best way to zone a system – zone valves or zone circulators – but this session will not take those discussions into consideration. In this one-hour Taco Tuesday webinar presented by Dave Holdorf, Jason Kockx and John Barba, we are going deep into the new and exciting zoning controls, the Switching Relays and the Zone Valve Controllers. Discover what’s new, what’s the same and what the excitement is all about as we dive into the best way to optimize system control and maximize efficiency like never before!

Deep Dive: Variable Speed, Delta T Circulators and System Performance – 1 PDH
Presented by John Barba, Dave Holdorf, and Jason Kockx
Taco has been manufacturing variable speed delta T circulators for over 25 years. In this one-hour Taco Tuesday webinar, we are going to review the circulators and their performance curves, but we are also going to review what they can do to increase the system’s performance as well as the comfort level in the home.

System Curves and Pump Curves - 1 PDH
Presented by John Barba, Dave Holdorf, and Jason Kockx
If you want to get to the heart of residential hydronics, you’ll need to understand System Curves, Pump Curves and how they interact. Flow, head loss and circulator selection have more to say about system performance than we’ve ever given them credit for, and in this fast-paced, fact-filled hour we’ll show you why.
You’ll learn where pump performance curves come from and what a system curve is. And most importantly, you’ll learn why knowing both may change the way you look at circulator selection, even if you’re using an ECM variable speed circulator.
