Test results
Congratulations. You have passed the test and completed the 48 - Heating systems in commercial buildings
Achieved badges:
Q: What is it a correctly balanced system helps with?
A: Keeping return temperatures high
Q: What is it a correctly balanced system helps with?
A: Adapting performance to increase flow
Q: What is it a correctly balanced system helps with?
A: Keeping Delta T at the design flow level
Q: What is the main reason for a heating system being out of balance?
A: Owners buy pumps that are oversized
Q: What is the main reason for a heating system being out of balance?
A: The new pump can’t work with the old pump
Q: What is the main reason for a heating system being out of balance?
A: Commissioning of heating systems is generally poorly done
Q: How does Grundfos GO Remote help you?
A: Makes it easy to find pumps hidden away in small and crowded technical rooms
Q: How does Grundfos GO Remote help you?
A: Guides you step-by-step for correct pump setup and commissioning from a smartphone
Q: How does Grundfos GO Remote help you?
A: Enables you to intervene and reset FLOWLIMIT, if pressure and flow are incorrect
Q: What is the efficiency increase achieved if FLOWLIMIT is enabled in an intelligent circulator pump?
A: 10%
Q: What is the efficiency increase achieved if FLOWLIMIT is enabled in an intelligent circulator pump?
A: Less than 10%
Q: What is the efficiency increase achieved if FLOWLIMIT is enabled in an intelligent circulator pump?
A: The primary benefit is improved occupant comfort, not system efficiency
Q: Which of the following statements is correct?
A: For flue gas to condensate, the return temperature must be as high as possible
Q: Which of the following statements is correct?
A: For flue gas to condensate, the return temperature must be as low as possible
Q: Which of the following statements is correct?
A: The more efficiently a system operates, the more gas is required
Q: What can happen if systems and zones are poorly balanced?
A: This may result in too high Delta T, which means you pay too much for energy
Q: What can happen if systems and zones are poorly balanced?
A: Nothing to worry about, if the extra energy costs don’t bother you
Q: What can happen if systems and zones are poorly balanced?
A: This may result in decreased Delta T and lower end-user comfort
