Frequently Asked Questions

• How to choose the right output (head) for a circulation pump? The head (delivery height, given in metres) must cover the pressure losses of your specific heating circuit - these depend on the pipe length, the number of radiators/circuits and the resistance of the fittings. For a typical family house a pump with a head of up to 6 m is usually sufficient; for larger or multi-zone systems a higher head (8 m or more) is chosen - if in doubt, consult a heating engineer who can size the flow rate and head precisely for you.
• What does the connection size (e.g. 6/4") mean on a pump? This is the threaded connection of the pump to the pipework - it must match the pipe diameter in your system, or a reducer can be used. This value must not be confused with the suction/discharge DN, which indicates the bore of the pump port itself.
• What is the difference between a single-speed and a multi-speed/electronic pump? A multi-speed pump lets you switch manually between several fixed power stages according to the system's needs, while an electronic (controlled) pump continuously adjusts its output on its own according to current demand - this means lower electricity consumption and generally also quieter operation.
• Why is the pump noisy and can this be resolved? Increased noise can be related to an incorrectly set (too high) power stage relative to the system's needs, air present in the system, or the fact that the chosen model is not primarily designed for quiet operation in residential spaces. If the noise bothers you, we recommend trying a lower power stage, thoroughly bleeding the system, or considering an electronically controlled model, which is usually quieter, especially at partial output.
• Must installation be carried out by a professional? Fitting the pump itself into already-prepared piping (with the correct threaded fittings) can be handled by a skilled DIY-er, but we recommend having the electrical connection to the power supply and commissioning, together with balancing the whole system, checked by a heating technician.
