The heating circulation pump Alpha 3 from Grundfos is an innovative product with high quality and functionality, which also fulfills ecological requirements. It is the first circulation pump which allows doing a simple hydraulic adjustment – which is crucial for the efficient operation of heating systems. The adjustment is done by using the ALPHA READER. It is temporarily fixed at the pump’s head, the operating data is read out and transmitted to the Go Balance App via Bluetooth. The App then supports the user in doing the hydraulic adjustment. Naturally, ecology doesn’t fall short: the Alpha3 reaches an energy efficiency index (EEI) of less or equal 0.15, which is the highest efficiency in its class.
