How to check if it is the part for your boiler
The part reference, model, and equipment revision must be verified against the manufacturer's documentation.
- Locate the white label on the top of the motor and read the designation INTHB15/5-2 and the reference Wilo 4520784.
- Check the power ratings on the label: I = 60 W and II = 83 W. The motor body should indicate 230 V, 50 Hz, and TF95.
- Check if your pump also shows 0020072591 and 401891. If it has another reference, such as 0020084524 or 0020087275, do not request it without consulting us.
- Read the exact model on the boiler's rating plate, including its suffix (F25-A/1, F30-A/1 or NOx F24).
- Compare the format with the photos: Wilo motor with black plastic hydraulic body, connection ports, and cable with green connector.
- If in doubt, send us a photo of the pump label and the boiler control board via Contact, or call 911 17 77 77.

Where is the code for this pump and what do the marked numbers mean?
On the white label at the top of the motor, it has the designation Wilo INTHB15/5-2, the reference Wilo 4520784, and the power ratings I = 60 W and II = 83 W.
