Generated explanation

This simplified schematic depicts a boiler supplying three radiant heating zones through a supply manifold, with a separate circulator pump on each zone branch. Red piping carries heated water to the serpentine radiant loops, and blue piping returns water through a common return manifold to the boiler; arrows indicate flow direction. A domestic water supply connects to the heating circuit, and an expansion tank hangs from the supply piping near the boiler. A connection between the supply and return piping is identified as requiring a mixing valve if the water temperature exceeds 120°F.
