As radiant heating and cooling systems continue to grow in popularity for their superior comfort, energy efficiency, and quiet operation, the importance of proper system installation cannot be overstated. A poorly installed system—no matter how advanced its components—can fall short of expectations, leading to hot and cold spots, energy waste, or costly callbacks.
The Radiant Professionals Alliance (RPA) provides superior comprehensive educational activities and innovative product awareness. This was evident at the 2025 AHR conference held in Orlando Florida. The RPA hosted eight sessions providing education to professionals and students. From the eight sessions, I would like to highlight five that deal with industry patterns, installation practices and innovative design.
Radiant heating and cooling systems integrated with geothermal ground source heat pumps (GSHPs) offer an energy-efficient, comfortable, and sustainable approach to indoor climate control. This combined system leverages the stable temperatures of the Earth to provide heating and cooling through radiant surfaces, most commonly on floors but also on walls or ceilings.
As the building industry shifts to electrification, decarbonization, and high-efficiency infrastructure, radiant heating and cooling professionals lead the change. At this year’s AHR Expo in Orlando, FL, Greg Cunniff of Egg Geo presented 'Future of BEST – Net the Energy with Community Thermal Energy Networks'.
Advancements in the plumbing industry are driven by U.S. Department of Energy regulations, with new efficiency standards for fractional horsepower pumps set for 2028. Plumbing & Mechanical's Nicole Krawcke discussed these changes and performance improvements with Becky Henderson from Grundfos Pumps.
Edward Little High School in Auburn, Maine, utilizes an efficient radiant floor heating system designed by Harriman Associates, using lower temperature water and primarily geothermal energy for a comfortable, sun-like warmth.
The 2024 Uniform Mechanical Code's Chapter 17 introduces Thermal Energy Networks (TEN), enabling buildings to independently manage heating and cooling sustainably, reducing environmental impact and enhancing energy efficiency across communities.
In Ottawa, a homeowner's dream of a luxury clubhouse with an outdoor pool comes to life with True North Mechanical's innovative heating system, ensuring a perfect New Year’s Eve party despite the freezing temperatures.
The Radiant Professionals Alliance (RPA) is enhancing energy efficiency through innovative hydronic systems under new leadership, focusing on collaboration, education, and strategic partnerships.
The Radiant Professionals Alliance (RPA) enhances the radiant industry through education, advocacy, and member support. It offers training, networking, and updates like a new website and geothermal partnerships. Members can participate in committees and events such as the 2025 AHR Expo.
