On Nov. 19 at 12 p.m. CST, Bob “Hot Rod” Rohr and Cody Mack, Caleffi training and education managers, will team up to share secrets to success in maintaining a “happy” hydronic system during this one-hour webinar.

During the webinar, attendees will learn: 

  • Is my fill pressure adequate or do I need a pump cart for filling and flushing?
  • When should I use a system cleaner additive?
  • Where is the best location for purge valves?
  • Are the steps different for filling, purging and cleaning new systems compared to old? and 
  • I’m ready for my final fill. What pressure should I leave the system at?

Recently recognized with the 2020-2022 Carlson-Holohan Industry Award of Excellence and a fun-loving industry veteran, Hot Rod is sure to delight the audience with his expertise and quick wit. He travels from sea to shining sea, sharing his 35-plus 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 of 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, his thoughtful delivery and common sense product approach will delight the audience.
