Grundfos Alpha 3 Pumps and Circulators

The first home circulator with integrated Bluetooth for professional balancing

The Grundfos Alpha 3 range redefines the standard for residential circulators. Thanks to native Bluetooth connectivity, this pump communicates directly with your smartphone via Grundfos apps, making installation, monitoring, and balancing the system simple and straightforward.

Why choose the top of the range Alpha 3?

• No Extra Accessories: No Alpha Reader required. The data reader is integrated into the pump.
• Guided Hydronic Balancing: Use the Grundfos GO Balance app to balance your radiators or underfloor heating and save up to 20% on fuel.
• Smart Scheduling: Set night modes, summer modes (to avoid blocking) and time schedules directly from your phone.
• Professional Reports: Ideal for installers: generate a PDF report at the end of the job to send to the customer.

Alpha 3 vs. Alpha 2: What's the real difference?

At first glance, they appear similar, but the Alpha 3 offers a superior level of interaction. While the Alpha 2 is an "automatic" pump, the Alpha 3 is a "connected" pump.

The key difference is the built-in two-way Bluetooth . With Alpha 3, you can use your smartphone as an advanced remote display. You can read the exact flow rate, head, consumption, and error history without having to decipher codes on the pump's small display.

Performance and Reliability

In addition to the smart part, Alpha 3 maintains the robust mechanics that made Grundfos famous:

• Vibrating descaling: In case of limescale deposits, the pump vibrates when starting to break down the scale.
• Dry run protection: If water runs out, the pump stops before it gets damaged.
• Summer Mode: The pump turns on for 2 minutes every 24 hours during the summer to prevent it from freezing in October.
