Heater ventilation

https://imgur.com/a/pGp5Ju5 I live in Sweden and I recently moved to a new apartment. The heaters have an old ventilation system that draws a lot of cold air in the room. As you can see from the image there is a slit that is opened towards the heater and a knob on the side that can move up and down 2-3 cm. I thought it was connected to the slit but it's likely not. I tried to close the slit manually with a broom but can't understand if it's not supposed to rotate or it's simply very old or stuck. The vent box itself is very cold compared to the wall to which it's mounted. I was thinking to insulate it with some thermal-insulation foil but the slit would still remain open anyway Have you ever seen such a system? Any suggestions? Cheers :) submitted by /u/NectarinePretty3173 [link] [comments]
