cody and bob caleffi

A clean hydronic system is a happy hydronic system. That means that purging and filling are vital keys to success. Bob "Hot Rod" Rohr and Cody Mack, our training and education managers, team up in order to share their secrets to success in maintaining a "happy" hydronic system at the next Coffee with Caleffi™ webinar on Thursday, Nov. 19 from 12 noon-1 p.m. CST.

Recently recognized with the 2020-2022 Carlson-Holohan Industry Award of Excellence and a fun-loving industry veteran, Rohr is sure to delight the audience with his expertise and quick wit. He travels from sea to shining sea, sharing his 35+ years' of experience as a plumbing, radiant heat and renewable energy contractor. Rohr is a regular contributor for industry publications where he enjoys putting his rubber-to-the-road experiences to pen.

Mack has nearly 20 years’ experience as an 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.

The one-hour educational webinars are free and are intended for contractors, designers and wholesalers. A Certificate of Attendance is emailed to attendees following the event for continuing education consideration. Registration is required; please visit our website at for details.
