IBO OHI 15-60/130

Product detailed description

Circulation pump for all water distribution in the home, IBO OHI 15/60-130

IBO OHI pumps are equipped with a 3-speed mechanical rotor switch, ensuring optimal electricity consumption depending on the specific conditions in the home.

Main advantages of the OHI model range pumps:

• savings on electricity and boiler fuel
• standard dimensions
• ease of use and installation
• long trouble-free operation
• materials and parts are resistant to an aggressive water environment and require no additional maintenance costs
• the design allows the control unit to be separated from the pump in the event of a fault or maintenance
• quiet operation even at higher speeds thanks to the bearing material used

Frequently asked questions

• How do I choose the correct output (head) of 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 is chosen (8 m or more) - 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") of 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 of the suction/discharge port, which indicates the bore of the pump's own port.
• 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 as needed by the system; an electronic (controlled) pump adjusts its output smoothly and automatically according to current demand - meaning lower electricity consumption and generally 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 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 output level, thoroughly bleeding the system, or considering an electronically controlled model, which is usually quieter especially at partial output.
• Must the installation be carried out by a professional? Fitting the pump into already-prepared pipework (with the correct union fittings) can be managed by a competent DIYer; we recommend having the electrical connection to the power supply, commissioning, and balancing of the whole system checked by a heating technician.
