ᐅ How does the heating system work in our new rental apartment?

Hello,

we recently moved into an old building that is listed as a historic monument. The front facade is not insulated.

The heating system is different from what we are used to, and we are wondering how it works.

In our previous apartment, we had a boiler in the kitchen and a radiator thermostat in the living room. The heating technician explained to me how to use these optimally, including the temperature settings on the radiator valves (1 = 12°C (54°F), 2 = 16°C (61°F), 3 = 20°C (68°F), and so on).

Now, in our new apartment, we no longer have a boiler or radiator thermostats.

We have older “ribbed radiators” (as I call them) and a heating system with a boiler in the basement. The consumption value can be read on a pipe assigned to each rental unit.

Is it possible to read a usable consumption value there, or is this converted somehow?

Heating costs are billed by the landlord, but they have not provided us with any information about the heating.

The problem is: if I turn a valve even just to 0.5, the radiator seems to heat up strongly within a few minutes. After a while it cools down somewhat, but there is no noticeable difference compared to setting it to 5.

Could it be that the valves only have “on” and “off” positions?

Regards

. . We are not familiar with houses and apartments, and therefore not with the heating system.
So how are we supposed to know how the heating works?
You need to upload photos.

Wherever you turn something without a thermostat valve: if there is a "half" setting, it logically cannot be that there are only "on" and "off" positions meaning fully open or fully closed (at least that’s my reasoning — which is the same on both sides of the cathedral and Deutz).

The controller has the standard scale 0 * 1-5.

Here are the pictures; I hoped my description would be sufficient.

In the last photo, there is a thermostat, right?! Why do you say there isn’t one?
At least it looks like a thermostat to me. I had one like that in my apartment back then, and my parents still do.

For me, this is a radiator valve, but yes, it seems to be called a thermostat.
What I mean is that we don’t have a central control system, no "room thermostat".

Sorry.
