Coffee with Caleffi™ Schedule

Optimizing Mixing Valves in DHW Systems
Thursday, April. 22, 2021
12 noon - 1:00 p.m. CDT 

Mixing valves are used every day in domestic hot water (DHW) systems. Whether you’re designing a system with a mixing valve or servicing an existing installation, there are a number of considerations in order to ensure accurate control of the water temperature. Don’t let the mixing valve be your go-to fall guy when expectations aren’t met! Cody Mack will come alongside our audience to help them design, install AND maintain a trouble-free DHW application.

You'll learn:

→ What is recirculation creep and how is it prevented?
→ Why is there a maximum pressure differential between hot and cold on a mix valve?
→ Sizing is based on high-flow, but what about low-flow considerations?
→ What is the impact of water quality on a valve?
→ I want 120°F from my mixing valve. What should I set my source to?
→ What is Cv? How is it applied?

Mack has nearly 20 years’ experience as installation contractor, service technician, application engineer and most recently training manager for Caleffi. He pounds the pavement educating Boomers, Gen-X’ers, Millennials and beyond. When not on the road, he’s often in the Caleffi lab experimenting with product design solutions. A family man, gear-head and motorcycle-enthusiast, our audience will appreciate his thoughtful delivery and common sense product approach.

Coffee with Caleffi technical training webinars are free and intended for contractors, designers and wholesalers. By submitting your webinar registration, you are consenting to email communications to keep you up-to-date on industry news.

A Certificate of Attendance is emailed to attendees following the webinar for continuing education consideration.

Find It & Fix It
Thursday, May 20, 2021
12 noon - 1:00 p.m. CDT

How good are your hydronic system diagnostic skills? Can you spot errors while the design is still conceptual and change the layout to prevent problems? How about uncovering errors after the hardware is installed? Can you come up with a “minimally-invasive” approach to right the wrongs?

A favorite to the webinar series, John Siegenthaler, P.E will present several problematic hydronic system scenarios and show you what’s wrong based on the fundamentals. He will also describe how to fix these problems at the design stage and, if necessary, after the installation fails to deliver it’s expected performance.

Here's what to expect on your path to perfection:
→ Can the supply tees for several secondary circuits all be grouped together along the primary loop?
→ Is it necessary to use a hydraulic separator in systems that have a buffer tank?
→ Can a 1 inch thermostatic mixing valve be used to supply a manifold station that requires 9 gallons per minute flow rate?
→ Does a boiler bypass pipe with its own circulator protect a boiler from sustained flue gas condensation?

A seasoned industry leader and passionate teacher, John shares his over 40 years’ experience in the understanding and proper application of water-based engineering principles with our audience. He is the principal of Appropriate Designs and a regular contributor to industry publications.

A Certificate of Attendance is emailed to attendees following the webinar equivalent to 1.0 PDH for continuing education.   Please verify with your state/province for fulfillment compliance.
