hot rod rohr coffee with caleffi 3.19.20

Maintaining the health of water circulating within hydronic and plumbing systems is vitally important for optimal performance. The ideal fluid within these systems would have no impurities, air bubbles or dissolved gasses. But have you experienced such symptoms as insufficient flow, pump air lock, low temperature, noise, low heat transfer or corrosion? These are telltale signs of excessive air contained in a system. Bob "Hot Rod" Rohr, Caleffi training and education manager, will discuss how air enters a system, common air related symptoms and discuss venting solutions for successful air removal at the next Coffee with Caleffi™ webinar on Thursday, March 19 from 12 noon-1 p.m. CDT.

Recently recognized with the 2020-2022 Carlson-Holohan Industry Award of Excellence, Rohr is sure to delight the audience with his expertise and quick wit. He travels from sea to shining sea, sharing his 30+ years' of experience as a plumbing, radiant heat and renewable energy contractor. Rohr is a regular contributor for industry publications where he puts his rubber-to-the-road experiences to pen.

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 audits. Please visit our website at for schedule details and registration.
