Coffee with Caleffi™ Schedule

Controlling Pressure in Plumbing Systems
Thursday, June 27, 2019
12 noon - 1:00 p.m. CDT

Water pressure within a plumbing system should remain within a predetermined range as conditions vary both inside as well as outside the building in order to provide adequate flow at the various plumbing fixtures and prevent unsafe conditions. Accomplishing this requires an understanding of what causes pressure changes and knowing how to apply various devices used for pressure control. Bob Rohr and Cody Mack, Caleffi training and education managers and maestros of the trades, walk through the issues and share their compelling solutions.

You'll learn:
→ What are typical water pressures within buildings?
→ What problems can occur with inadequate pressure? Excessive pressure?
→ Thermal expansion, water hammer, back-syphoning and pressure fall-off: what are they?
→ What are the roles of expansion tanks, T&P valves, pressure reducing valves, backflow preventers and others?
→ What unique issues do private well systems present?

Mack has nearly 20 years’ experience as installation contractor, service technician, application engineer and most recently training manager for Caleffi. A family man, gear-head and motorcycle-enthusiast, our audience will appreciate his thoughtful delivery and common sense product approach.

A familiar and favorite speaker to the webinar series, Hot Rod 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.

Lowering Water Temperature in Existing Hydronic Systems 
Thursday, July 25
12 noon - 1:00 p.m. CDT

As the North American market for high-efficiency boilers and renewable energy heat sources continues to expand, there’s increasing need for hydronic delivery systems that complement those heat sources. In new construction situations, there are ample methods and materials for creating low-temperature hydronic heating distribution systems. However, tens of thousands of existing buildings have “high-temperature” distribution systems that severely limit the potential of these contemporary heat sources. John Siegenthaler, P.E. will present techniques to evaluate those existing systems for potential operation at significantly lower water temperatures. He will also show practical methods of modifying them for low-temperature operation and expanded capabilities such as room-by-room zoning.

You'll learn:
→ Is it practical to operate fin-tube baseboard at 120 ºF water temperature?
→ Should you add heat emitters to an existing series baseboard circuit?
→ What needs to be checked prior to using older cast-iron radiators in a modified hydronic system?
→ How can an older single zone distribution system be converted to room-by-room zoning?
→ Do all supplemental heat emitters added to an existing system have to be the same type?

A seasoned industry leader and passionate teacher, John shares his over 35 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.
