The bottom floor displays radiant tubing loops beneath the floor in each zone, symbolizing individualized heating control. The illustration includes the title “Radiant Heating Zones Explained” at the top, making it a strong visual companion for educational content about multi-zone hydronic heating systems and their benefits in comfort, energy savings, and system longevity.
