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.
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.
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.
Q: What is the added bonus of using a MAGNA3 pump?
A: Reliable condensation conditions increase system efficiency by 10% – which in turn means more cost-efficient operation, as also the amount of gas required is reduced thanks to the increase in efficiency.
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: What characterises the FLOWLIMIT technology?
A: The FLOWLIMIT technology makes it possible to set a max flow, which means that the design flow is never exceeded regardless of pipe diameter and pressure loss.
