- To remove air from the circulating water.
- To mix hot supply water with cooler return water.
Correct answer: To distribute and collect heated water to and from multiple heating zones or emitters.
Explanation: A manifold in a hydronic system serves as a central distribution point, routing heated water from a common supply line to individual heating zones or emitters (e.g., radiant floor loops, radiators) and collecting return water from them. Pressure regulation is done by expansion tanks, air removal by air eliminators, and mixing is typically done by mixing valves.
