Hydronic systems improve energy efficiency, indoor comfort, and long‑term flexibility by leveraging the superior heat‑transport properties of water, reducing air‑distribution losses and mitigating refrigerant‑related risks. Listen as Chris DesRoches, P.Eng., Business Development Manager of Heating & Cooling at Swegon, and Zachary Londo, P.E., Sr. Design Engineer at GF, discuss the wonders of water and reveal available hydronic system configurations and practical design strategies for integrating radiant, heat pumps, circulators, fan coils, mechanical equipment, and dedicated ventilation solutions across different building types.
