Frequently asked questions

• How do I choose the correct output (head) for a circulating 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 an average 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 technician who can size the flow rate and head precisely for you.
• What does the connection size (e.g. 6/4") on a pump mean? This is the threaded connection of the pump to the pipe - it must match the pipe diameter in your system, or a reducer can be used. This value must not be confused with the DN suction/discharge size, 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 manually switch between several fixed output levels according to the system's needs, while an electronic (controlled) pump automatically and continuously adjusts its output to actual demand - meaning lower electricity consumption and usually quieter operation.
• Why is the pump noisy and can this be fixed? Increased noise can be related to an incorrectly set (too high) output level for the system's needs, air present in the system, or the chosen model not being designed primarily for quiet operation in living spaces. If the noise bothers you, we recommend trying a lower output level, 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 threading) can be handled by a skilled DIYer; however, we recommend having the electrical connection to the power supply and commissioning, together with balancing the whole system, checked by a heating technician.
