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'.

The ANS2 is universal, field-adjustable and designed for simple calibration and instillation. 

A recent design approach for air-to-water and water-to-water heat pumps is "direct-to-load" piping. This method utilizes an inverter-driven scroll compressor, which operates across a wide range of speeds and can handle on/off cycling without the high inrush current typically seen in fixed-speed compressors.

Last month's column discussed piping for air-to-water heat pumps. A 2-pipe system allows staging but not simultaneous heating and cooling, while a 4-pipe system with motorized valves enables both modes of operation.

Air-to-water heat pumps, especially for larger systems, can be used in stages for efficient temperature control and flexibility, utilizing variable-speed compressors and specific piping setups to manage heating and cooling loads.

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.

Use the PIM Method (Preparation, Installation, Maintenance) for effective radiant heating installations, emphasizing clear project intent, proper manifold placement, and regular fluid maintenance to ensure efficiency.

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.

A review of a flawed hydronic heating system uncovers critical errors, such as improper circulator placement and restrictive mixing valves, leading to uneven warmth and corrosion issues. This underscores the need for proper design and installation in hydronic systems.
