Guide

How to check if reference 4521070 is the part for your boiler

Compare the label and the hydraulic assembly before choosing the spare part.

  1. Locate on your label INTHB15/6.7-2, 4521070 and 0020075437.
  2. The extension allows reading the model, the codes, and the power levels I (64 W) and II (85 W). The markings 230 V, 50 Hz, and TF95 are embossed on the motor cover.
  3. Compare the distribution of outlets, the fixings, the bleeder, and the cable connector with the gallery.
  4. In the detail of the green connector, you can compare the shape of the housing, its slots, and how the conductors fit in.
  5. Check the complete version of the boiler and the breakdown before placing the order; a family designation does not identify this variant.
  6. Inventory Alfonso notes Isofast Condens F35-A/1, Isomax Condens F35 B/1, and Isofast 21 Condens F30-B/1. These applications are warehouse annotations. Check the breakdown of your version and the configuration of the part.

Frequently asked questions

Frequently asked questions

Do 4521070 and 0020075437 appear in the same part?

Is only the motor advertised?
The photographs show the motor mounted on a multi-port hydraulic body, with a bleeder and cable. It is that configuration that you need to compare with your spare part.
Is it enough for my pump to be INTHB?
Compare the full designation, the two label codes, and the connections. The INTHB family includes other variants that are not identified by their general appearance.
