On the opening day of the AHR Expo in Chicago—Monday, January 22—the crew from Mechanical Hub was fully immersed in the very first Coffee with Caleffi Live from the Caleffi booth. There, emcees John Mesenbrink and Tim talked with industry powerhouses John “Siggy” Siegenthaler, Bob “hot Rod” Rohr, Eric Aune and Andy Mickelson about the lifelong learning in the trades.
From l to r: Emcee John Mesenbrink, John Siegenthaler and Bob Rohr
In the first half of the presentation, the hosts asked “Siggy” and “Hot Rod” where they go to find the resources they need to keep up in today’s contracting world. Having forgotten more than most have learned in a lifetime, where do these legends go to learn?
From l to r: Emcee John Mesenbrink, Eric Aune and Andy Mickelson
Part two featured Eric Aune and Andy Mickelson as they shared their point of view from the eyes of a business owner and working contractor, and discussed the importance of social media and its impact on learning.
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.

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.
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.

John Siegenthaler, P.E., a favorite to the webinar series, will discuss design details, challenges and lessons learned from a from a recent project profile of a modern hybrid approach utilizing an air-to-water heat pump system that checks all of the boxes during this 90-minute extended edition.
You’ll learn:
→ Back-up heating. When is it necessary?
→ Can a single 44 watt circulator supply all space heating flow for a 2,300 square foot house?
→ Does chilled water cooling and heat recovery ventilation require separate duct systems?
→ Can panel radiators operate at supply water temperature below 100 ºF on design days?
→ Where does an “extended manifold” piping system make sense?
→ How are 3-way diverter valves applied in air-to-water heat pump systems?
→ What are the advantages of multi-zone heating combined with single-zone cooling?

Air-to-Slab Heat Pump Systems
Thursday, Nov. 17
12:00 – 1:00 p.m. CST
Technical Content Level: Intermediate
Air to water heat pump technology is steadily gaining traction. When a heat pump’s coefficient of performance is maximized, energy efficiency and resiliency benefits are substantial. How can engineers, designers and installers effectively apply this emerging technology to high thermal mass floor heating applications? Which commercial systems are good candidates for this type of design?
Hydronics expert John Siegenthaler, P.E. will detail the approaches that can best utilize this technology.
You’ll learn:
→ Do all air to water heat pump systems need buffer tanks?
→ How does the thermal mass of a floor slab compare to that of a buffer tank? → What is a simple way to control a heat pump supplying a heated floor slab? → What are the benefits of using constant circulation in “garage-type” floor heating systems?
