I live in an apartment within a multi-family building (built in the early 2000s). My issue is that I cannot control the underfloor heating myself. It seems to adjust according to the outside temperature. In summer, there is little to no heating, while in winter, it’s quite strong. The controls in my apartment are always set to the lowest level. Still, the apartment is generally too warm, so I often have to tilt the window or take similar measures to regulate the temperature.
Attached is a photo of the underfloor heating system.

I tried opening and closing the red valves to completely shut off the heating during summer, but this had no effect.
Do you have any idea why I can’t regulate the underfloor heating and what could possibly be done about it?
Thank you.

If they are not properly installed, they won’t function correctly and might remain fully open. This could also explain why it is too warm.
Turning them manually might have contributed to this as well.
What does the landlord say, or is it your own property?

The landlord said at the time that I could turn the red handles at the bottom right to completely shut off the heating, at least during the summer. However, it keeps heating regardless.
I will contact the building superintendent to see if they know anything about it, and if not, I will call a tradesperson to have a quick look to check if it’s due to the settings or something similar.

The landlord is a miser; any good heating system should be able to turn off in summer, if only for economic reasons.
The rest has already been said by mycraft: check if the actuators are loose and whether a fuse might just be blown. Otherwise, the building manager will surely help, and it’s your money that you’re wasting.
