3: Which of the following statements is correct?
For flue gas to condensate, the return temperature must be as low as possible
3: Which of the following statements is correct?
The more efficiently a system operates, the more gas is required

4: What is the main reason for a heating system being out of balance?
Owners buy pumps that are oversized
You can find the answer here >
4: What is the main reason for a heating system being out of balance?
The new pump can’t work with the old pump
You can find the answer here >
4: What is the main reason for a heating system being out of balance?
Commissioning of heating systems is generally poorly done
5: What can happen if systems and zones are poorly balanced?
This may result in too high Delta T, which means you pay too much for energy
You can find the answer here >
5: What can happen if systems and zones are poorly balanced?
Nothing to worry about, if the extra energy costs don’t bother you
You can find the answer here >
5: What can happen if systems and zones are poorly balanced?
This may result in decreased Delta T and lower end-user comfort
6: What is the efficiency increase achieved if FLOWLIMIT is enabled in an intelligent circulator pump?
10%
6: What is the efficiency increase achieved if FLOWLIMIT is enabled in an intelligent circulator pump?
Less than 10%
