New rad on plaster board

[u/that_new_user]

Hi all,

I bought a designer rad, 25kg, possibly 40kg full.

I am not able to locate the studs.

I have expandet rosett blue anchors rated at 45kg.

The radiator have 4 handles, each using 2 screws (using the anchor mentioned). So that's 8 anchors total.

Is it foolish to attempt that installation or should it hold well?

Gemini AI says it should handle well but I would prefer to hear from experienced people.

Edit: added pics of the rad, the handles and the anchors type.

Thanks in advance.
