Systems that use either hot or chilled water require which components to circulate and control the water?

Systems that use either hot or chilled water require which components to circulate and control the water?

• A. Pumps and valves
• B. Only pumps
• C. Only valves
• D. No pumps or valves

Answer: (A)

Hydronic systems rely on two types of devices to move and manage water: pumps and valves. The pump provides the energy to move the water through pipes, overcoming friction and elevation differences. Valves regulate and direct that flow, isolating zones, throttling flow, and mixing or bypassing as needed to achieve the desired temperature and distribution. Without a pump, water won’t circulate; without valves, you can’t control where it goes or how much flows to each part of the system. Therefore, to circulate and control hot or chilled water effectively, you need both pumps and valves.
