April 14 : The Efficiency Workshop: Why Delta-T Variable Speed Pumping is ECM Gold – 1 PDH
Presented by John Barba, Dave Holdorf, and Jason Kockx
We all know that ECM circulator technology saves electricity, and that’s a good thing. A better approach is to utilize that technology to ensure your heating plant operates at its peak efficiency as well. To do that, you need to use a Delta-T variable speed circulator.
In this program, Dave, John, and Jason will share with you how Delta-T circulators work, why they use less electricity than a Delta-P variable speed circulator and, most importantly, how they can help enhance your overall system efficiency and performance rather than limit it.
We’ll also share with you the details of our exciting new Delta-T circulator and show you how it can be the industry’s only truly self-sizing circulator. You won’t want to miss this.
April 28: The Efficiency Workshop: Why Zone Valves Should Be Part of Any Efficient System – 1 PDH
Presented by John Barba, Dave Holdorf, and Jason Kockx
The age-old debate of zone valves vs circulators will never be settled, but one thing is for certain: If you want to install the most energy-efficient hydronic system possible, zone valves need to be part of the equation.
In this fast-paced, fact-filled session, John, Dave, and Jason will show you the math while comparing the electrical consumption of a zone valve system and a zone pump system. We’ll also expose a few myths about circulator life, operating cycles, and circulator sizing in zone valve applications. This one might change the way you look at zone valves and circulators.

May 5: Why Choosing The Right Circulator For Residential Hydronics Matters – 1 PDH
Presented by John Barba, Dave Holdorf, and Jason Kockx
We’ll say it simply: The circulator you choose can make or break system efficiency. The boiler may make the heat, and the heat emitters may deliver the heat, but the circulator facilitates the journey. Oversize it and you’ll limit, sometimes drastically, the efficiency of any system you install.
Join Jason Kockx, Dave Holdorf, and John Barba as they explain the fundamental (not to mention easy) steps to making sure your circulator is sized properly for the job. You’ll also learn how properly implemented ECM technology can help.

May 19: Why Sizing Your Domestic Hot Water Recirculation Pump Properly Can Save Your Plumbing System – 1 PDH
Presented by John Barba, Dave Holdorf, and Jason Kockx
The purpose behind a domestic hot water recirculation system is to get hot water to plumbing fixtures fast. But faster isn’t always better. It’s not an exaggeration to say that oversizing your DHW recirc pump can have catastrophic consequences, and we’d like to make sure that doesn’t happen to you.
Join Jason Kockx and the Taco Training Team to learn about new industry flow and velocity guidelines, and how to use that information to make sure your pump is sized and controlled properly for fast hot water delivery while protecting the plumbing system from pinhole leaks and other catastrophic failures.

June 9: Outdoor Reset Is Great, But Indoor Reset Might Just Be Better – 1 PDH
Presented by John Barba, Dave Holdorf, and Jason Kockx
Believe it or not, the concept of Outdoor Reset for hydronics has been around since the 1940s. It’s a given that increasing the boiler water temperature as it gets colder out and decreasing it as it gets warmer out will save energy.
But there may be a better way.
In this edition of The Efficiency Workshop, Dave Holdorf outlines the concept of Indoor Reset and how changing boiler water temperature based on what’s happening indoors might optimize system efficiency while also delivering superior comfort for your customers.

April 7 : Commercial Chiller Plant Concept Equipment and Piping Design – 1 PDH
Presented by Brett Zerba, Rich Medairos, P.E., Tony Furst, and Jason O’Neill
Designing a chiller plant can feel overwhelming, but it doesn’t have to be. In this session, we’ll walk through the fundamentals of chiller plant design, starting with where to begin and how to think about load, tons, and overall system layout.
We’ll cover how many chillers you need, where they belong, why cooling towers matter, and how pumps, NPSH, and piping all fit into the picture. By the end, you’ll have a clearer, more practical framework for approaching chiller plant design with confidence.
April 21: Using Flow Through Expansion Tanks in a Legionella Mitigation Plan – 1 PDH
Presented by Brett Zerba, Rich Medairos, P.E., and Tony Furst
Stagnant water creates risk. Flow-through expansion tanks are designed to keep water moving—and that makes them a valuable tool in Legionella mitigation strategies.
In this session, we’ll explain what flow-through expansion tanks are, how they’re applied, and how they align with ASHRAE Standard 12. You’ll learn how flow rates, tank sizing, and multi-port designs contribute to healthier domestic water systems and improved system reliability.
May 12: HVAC Hydronic Pump Curves and Selection – 1 PDH
Presented by Brett Zerba, Rich Medairos, P.E., Tony Furst and Jason O’Neill
Pump curves don’t need to be intimidating; they need to be understood. In this session, we’ll walk through how to read pump curves, identify BEP, understand design points, NPSH requirements, and efficiency lines, and see how variable speed curves change the game.
We’ll also show how parallel pump selection works and how our selection software simplifies the entire process. The goal is to achieve confidence and understand precisely why a pump was selected and how it will perform once it’s installed.
May 26: HVAC Pump Mechanical Seals and Minimizing Issues – 1 PDH
Presented by Rich Medairos, P.E., Brett Zerba, Tony Furst, Ric Turmel, and Jerry McKeone
Mechanical seals are small components with a big impact. When they fail, systems go down. In this session, we’ll cover how mechanical seals work, the types Taco uses, common materials, and why seals fail in the real world.
We’ll also discuss how variable speed operation affects seal life and what designers and operators can do to minimize issues. The takeaway: fewer failures, longer service life, and more reliable systems.
June 2: Deep Dive into Taco HVAC Solution (HSS) Software – 1 PDH
Presented by Brett Zerba, Rich Medairos, P.E., Tony Furst and Jason O’Neill
Designing hydronic systems doesn’t have to take hours. In this session, we’ll show how Taco HVAC Solution Software streamlines pipe sizing, system layouts, and component selection in minutes.
You’ll learn how the Wizard function works, how default values are applied, and how to generate DXF and PDF outputs quickly. It’s about designing smarter, faster, and with confidence.
June 16: How to Read a Psychometric Chart – 1 PDH
Presented by Brett Zerba, Rich Medairos, P.E., Tony Furst and Jason O’Neill
Psychrometric charts look complicated, until they don’t. In this session, we’ll demystify the chart by breaking down each line and term, including dry bulb, wet bulb, enthalpy, humidity ratio, and relative humidity.
You’ll learn how this powerful tool applies to real HVAC systems and how it helps you understand air, moisture, and energy in a whole new way.
