Remove or keep ancient radiators?

Good day everyone,

we recently bought a house and are a bit skeptical about the radiators on the upper floor.
Would you replace them or keep them as they are?
Have you ever seen such radiators and if there are any experts, what are the advantages and disadvantages of these? Thanks a lot in advance.

Are they connected to the heating circuit or are they storage heaters? They look like the ones we had, just painted white

Thank you for the answer. They are connected to the heating circuit. However, they do not necessarily heat well.

Then it's definitely not the asbestos-containing storage heaters

If they don't heat well, out with them. That's my opinion

To me, they look like simple panel radiators. We once had them in the office. In the second photo, they look quite low... anyway, panel heaters are panel heaters. Next time a scale would be helpful, right-angled corners always have the same measurements.

Thanks for the answer. They are connected to the heating circuit. However, they do not necessarily heat well.

What does "do not necessarily heat well" mean – do the radiators not get warm? Does the room not get warm? Do things need to be placed in front of them? In principle, such things are not bad.
