Ich habe festgestellt, dass sich die Einlass- und Rücklaufventile meiner Heizkörper von denen in Großbritannien unterscheiden, und die Wärmebildkamera zeigte, dass sie die gleiche Temperatur hatten.
Hat sich jemand mit dem gleichen System damit befasst? Wahrscheinlich muss ich sowieso einen Techniker rufen, wollte aber trotzdem eine Meinung haben.

Don’t know a lot about it but it being a single metal piece it doesn’t seem that weird to me that it has the same temp.
Input and output… if your radiator is up to temp, i dont see what is wrong with this.
What is the temperature of the radiator ?
Isn’t that what matters?
You’re measuring the temp of the metal. As they are connected they will be almost equal.
What you are thinking of is the water temperature of the input and output. That should be 10-12° difference according to your heating system, and is a means of knowing your installation is working efficiently, but I don’t think you should measure it this way.
It’s quite possible they have not been calibrated and are simply fully opened. You could try screwing off the caps, most likely you will be able to limit the water flow with a hex key socket underneath and see if that makes a difference.
I recently learned about the valve at the bottom of the radiator and I think it’s what your seeing: there is a valve (Source : YouTube https://share.google/6y5gUknJX3uAaRVvD) that can be opened or closed to regulate heath outflow from the radiator. It is used when an intervention is needed on the radiator and you need it isolated from the heating circuit but also to regulate heath outflow
Next to your boiler, there should be an warm and cold collector with lines going to each radiator. You should check the temperature difference between those.
Check the tweakers forum. There is a nice calculator available.
You are aiming an infrared camera at a reflective surface.
The measurement shows a low temperature due to the reflection of the opposite wall .
If you look at the part above it , you can see already a difference in temperature, but still not so trustworthy measurement. The painted parts are clearly better emitting the correct infrared radiation for your camera.
Like others said: it is the water temperature which defines the power of the radiator, not the surface temperature at the common connection part.
Since the radiator needs to dissipate the heat, its efficiency is only really important on very cold days, where you would put the heating curve quite high.
So better aim in preventing the losses of the other parts of your house, like doors windows roof….
What infrared camera are you using?
