Coffee with Caleffi Webinar Series

Domestic hot water (DHW) sizing and design is critical to optimize energy efficiency, reduce water waste, and improve safety.  Host Christoph Lohr, P.E. returns to the webinar series to detail the engineering methods that can help designers right-size their hot water return (HWR) system.  He will recap the September ’23 Coffee with Caleffi™ webinar (Ten Things to Read more

Domestic hot water (DHW) sizing and design is critical to optimize energy efficiency, reduce water waste, and improve safety.  Host Christoph Lohr, P.E. returns to the webinar series to detail the engineering methods that can help designers right-size their hot water return (HWR) system.  He will recap the September ’23 Coffee with Caleffi™ webinar (Ten Things to Know About DHW Return Design) and discuss three critical items regarding DHW return design:

  • Balancing Valve Selection Impact on HWR System Sizes
  • The Equations that Govern Right-Sizing Hot Water Return Systems (Hardy Cross Methodology)
  • Pipe Routing and Plumbing Fixture impact on Hot Water Return System Design

Christoph is IAPMO’s Vice President of Technical Services and Research.  As part of his duties he provides industry leadership through participation in strategic industry initiatives, and provides technical support to all IAPMO’s business units as needed. Christoph has over a decade of experience in designing plumbing systems and has a reputation as a results-oriented expert, particularly in the realm of balancing waterborne pathogen prevention and water sustainability.  He is a distinguished graduate from the Virginia Military Institute, with a Bachelor of Science in Mechanical Engineering.

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.

With energy efficiency being one of the four decarbonization pillars in the U.S. Department of Energy’s Industrial Decarbonization Roadmap, the goal of achieving a low-carbon economy and attaining carbon neutrality is possible with the use of radiant heating and cooling, hydronic hot-water heating, and chilled-water systems. Guest speaker Hailey Mick will explain how a thoughtfully Read more

With energy efficiency being one of the four decarbonization pillars in the U.S. Department of Energy’s Industrial Decarbonization Roadmap, the goal of achieving a low-carbon economy and attaining carbon neutrality is possible with the use of radiant heating and cooling, hydronic hot-water heating, and
chilled-water systems.

Guest speaker Hailey Mick will explain how a thoughtfully designed hydronic system can provide a compelling solution for comfort, efficiency, and Indoor Environment Quality (IEQ) benefits at the next Coffee with Caleffi webinar on Thursday, Dec. 21 at 12:00 p.m. CST.

Mick is an Engineering Business Development Manager at Uponor North America. She has 17 years of experience in the commercial HVAC industry. She holds a Bachelor of Chemical Engineering from Auburn University and is a member of ASHRAE, ASHE, ASPE, and the Uponor Sustainability Core Team.

A Certificate of Attendance is emailed to attendees following the event for continuing education audits. The monthly educational webinars are free and are intended for engineers, contractors, designers and wholesalers.

Air-to-water heat pumps provide a way to migrate existing hydronic heating systems supplied by fossil fuel boilers to sustainable electric energy.  In many projects there are compelling advantages for retaining the existing boiler and adding the heat pump to create a “dual-fuel” system.  These systems will likely be the most common application for air-to-water heat Read more

Air-to-water heat pumps provide a way to migrate existing hydronic heating systems supplied by fossil fuel boilers to sustainable electric energy.  In many projects there are compelling advantages for retaining the existing boiler and adding the heat pump to create a “dual-fuel” system.  These systems will likely be the most common application for air-to-water heat pumps in the near future as carbon reduction regulations reshape the market.

You’ll learn:
→ What’s the highest water temperature an air-to-water heat pump can produce?
→ Are buffer tanks always needed in systems with air-to-water heat pumps?
→ Should air-to-water heat pumps be connected in series with boilers?
→ Can air-to-water heat pumps be retrofitted to systems that use fin-tube baseboard?

Hydronics guru John Siegenthaler, P.E. will discuss the benefits of dual-fuel systems while examining the technical details for piping and controls in this 90 minute extended Coffee with Caleffi webinar edition on Thursday, Nov. 30 at 12:00 p.m. CST.

Siegenthaler is a seasoned industry leader and passionate teacher, eager to share his over 40 years’ experience in the understanding and proper application of water-based engineering principles with our audience.
