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: 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: 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: 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 happens if a heating system is imbalanced?
A: Operating costs are increased
Q: What happens if a heating system is imbalanced?
A: The building will be too hot
Q: What happens if a heating system is imbalanced?
A: The pump will vibrate excessively
