Sample interview questions: Can you explain your knowledge of different types of balancing methods used in hydronic systems and their benefits?

Sample answer:

1. Manual Balancing:
2. Involves adjusting individual valves or dampers in the system to achieve the desired flow rates and temperatures.

3. Benefits:

   • Simple and cost-effective method.
   • Provides precise control over flow rates in each circuit.
   • Can be used in both new and existing systems.

4. Automatic Balancing:

5. Utilizes pressure-independent control valves (PICVs) or variable flow valves (VFVs) to automatically adjust flow rates based on system demand.

6. Benefits:

   • Maintains constant flow rates regardless of changes in system pressure or load.
   • Eliminates the need for manual balancing.
   • Improves system efficiency and reduces energy consumption.

7. Thermostatic Balancing:

8. Employs thermostatic radiator valves (TRVs) or zone valves to regulate flow rates based on temperature.

9. Benefits:

   • Provides individual room temperature control.
