Correct
01.
Q: How can the MAGNA3 pump ensure optimum condensation?
A: The FLOWLIMIT technology built into the MAGNA3 makes it possible to set a max flow and eliminate the potential overflow area to ensure that the return temperature stays below 57°C.
Correct
02.
Q: What are the benefits of using the handheld controller Grundfos GO with the MAGNA3 in terms of balancing?
A: The FLOWLIMIT function can be accessed remotely via Grundfos GO and the flow limit can be set in no time to make commissioning easier than ever.
Correct
03.
Q: What characterises a heating system’s life cycle costs?
A: The running costs are significantly higher than the initial investment. A ratio of 20:1 is not uncommon.

Q: Why is it important to keep an exact flow in condensing gas boiler applications?
A: Condensation of flue gas is only possible at a very high flow.
Correct
05.
Q: What makes balancing heating systems in commercial buildings a challenging task?
A: The distance from the pump to the final consumer means that the pressure can vary widely depending on the flow.
Correct
