Q: What are the consequences of an unbalanced system?
A: An unbalanced system will add to the energy consumption and also affect the indoor climate of a building.
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 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 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.
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: 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.
