Merry xmas everyone.
I've a studio flat in my house which has 4 radiators and out of those 4 one is completely cold and the other is partially cold. I've 16 radiators in the house which are powered by a Vailant system boiler. To fix the problem, I spent some time today to balance them, primarily the upstairs one by completely closing the return return valve on all the rads and then opening them up about a quarter. This has improved the situation somewhat in the studio by getting the one a bit more hot but its still cold in the middle from the bottom. The other one is still cold, though I can feel the pipe with thermostatic valve getting some hot water.
I've the feeling the hot water is not getting distributed enough to those rads, any idea what can I do to improve the situation?
