Discuss Grundfos Alpha v UPS sorry cross post in the UK Plumbers Forums area at PlumbersForums.net

I think that pump is a 34W, Alpha 1 Model B., thats why all the settings showed the same power.
Its circulating ~ 1.3m3/hr, 21.7LPM at a 4.5M head, (this can be checked by changing to PP2 where the power should fall to ~18W to give 0.9m3/h, 15LPM at a 2.2M head).

The UPS 3 which is a 60W pump will give the 1.3m3/hr on CC2 which will be less noisy but if a greater flowrate is required then it will have to be changed to CC3 which should give ~ 1.5m3/hr, 25LPM at a 5.8M head but might still be quieter than the Alpha 1 as the power at ~ 44W will be less than its 60W max so running a little slower.
