Q3 2025

OUR PURPOSE

The Radiant Professionals Alliance (RPA) is advancing intelligent hydronic heating and cooling systems to transform comfort in buildings. Since 1994, we've championed the efficiency and health benefits of hydronic radiant systems, driving progress through education, standards development, and strategic partnerships. We’re harnessing water’s potential as an energy source to pave the way toward a carbon-neutral future.

FROM THE TECHNICAL DESK

Alliance Members,

Live from AHR 2025

We captured eight standout sessions on-site at this year’s AHR Expo. These conversations featured industry leaders sharing insights on radiant design, workforce development, and the future of sustainable heating and cooling.

If you missed the live event, now is a great time to catch up and add the playlist of our eight amazing speakers to your list.

AHR Expo 2026 will take place in Las Vegas, NV, Feb. 2-4. The world’s largest HVACR event brings together manufacturers, engineers, contractors, and industry professionals from across the globe. The show features thousands of exhibitors showcasing the latest innovations in heating, ventilation, air conditioning, and refrigeration. It’s the premier platform for networking, discovering new technologies, and staying at the forefront of the HVACR industry, and the RPA will once again be offering a radiant education track. We’re still looking for 1–2 more speakers. If you’ve got a story to tell, reach out soon; the lineup is already shaping up to be a strong one. Sign up today!

Blue Book Revision – September Meetings

This fall, the Radiant Heating and Cooling Installations Guide (a.k.a. The Blue Book) is getting a fresh revision. Beginning in September, we’ll be holding meetings to review, revise, and prepare for republishing this industry staple.

Check your email to register and get involved as an author, contributor, or reviewer. Your input will shape the guide that continues to set the standard in our industry.
