Hello guys
could you help please, i don't understand what went wrong, i had the top room radiator not working for a while, i googled about the problem and i have understood that the air might be the problem, and the boiler was showing slightly under 1Bar pressure which is not normal.
i got the bleeding key for the radiator, i got all the air out, i've understood that if you bleed the radiator the pressure will automatically drop, and from what i have understood the pressure must be 1.5Bar when the heating is off in cold water
using the Valve (1) i adjusted the pressure to 1.5bar, and then turned the heating on, everything seems to work like a charm, pressure OK in the green zone, and the radiator worked again
but after 4 hour from that, i have checked the pressure again just to make sure everything is working ok, i knew that the hot water might cause the pressure to raise, which it did but the pressure went straight to 3.5Bar and it stayed there
i though i put more water than i should put in, i turned the heater off and bleed the first floor radiator about 15L
the pressure when down under 2bar but it raised again, there's like clicks sound in the heater it is like the boiler is off then on and the pressure goes back to around 3.5bar
i though i didn't close the valve (1) nicely so i have checked it and made sure it was tight, but still the boiler pressure goes up
could you please advice for what i have to do next, thank you very much
the boiler ( i can't tell the mark)
valve general
valve close up
pressure bar
bleeding valve
