How to check if reference 59895542 is the part for your boiler

The part reference, model, and equipment revision must be verified against the manufacturer's documentation.

1. Check the label on your pump motor: it should say Grundfos UPS 15-50 AO 130.
2. Compare the powers: 45, 70, and 95 W (0.21 / 0.32 / 0.42 A).
3. Check the model and power on your boiler's label: the Eolo Star and Nike Star of 24 kW have a different pump.
4. If your boiler is an Immergas Eolo Star 23, confirmed: for this pump. Another model? Send us a photo of your pump's label and the boiler's PCB from Contact.

El folleto oficial de la Eolo Star 23 da como circulador la «Grundfos UPS 15-50 AO», el modelo de esta etiqueta. Si es la 1.015561: Immergas la sustituye por el kit 3.021396, que vale también para 1.020573 (investigación de la #33). Mismas potencias y condensador que la #41 (UPS15-50 J1 CIAO, P/N 597/2501M, también anotada para la Eolo Star 23), pero otro modelo, otro P/N y otra presión máxima (6 frente a 3 bar). Sin confirmar: que sean la misma pieza.
