Insufficient heat - The pump's performance is too low

What does Insufficient heat mean?

The heating system is not providing enough heat, indicating that the pump is not circulating water effectively or at the required rate.

• Pump operating at a lower speed or output than required for the system's heat demand.
• Incorrect control mode selected in the Grundfos GO Remote app.
• Suction head set too low for the application.

Click steps to track your progress.

1. 1

   Access the Grundfos GO Remote app and review the pump's current operating mode and settings.

2. 2

   Increase the pump's suction head or adjust its control mode to deliver higher performance and flow.

3. 3

   Ensure the pump is operating in a mode appropriate for your heating system (e.g., radiator mode, underfloor mode).

4. 4

   Check that system valves are fully open and there are no blockages restricting flow.
