radiators will not get up to temperature upstairs

[boardy_61]

Hi there, i have a problem with my upstairs radiators, my downstairs one,s are fine and get up to temperature nice but the upstairs remain luke warm, i have tried to bleed them but when i open the bleed screw no air seems to escape and there is no water comeing out either, any help would be appreciated, thankyou.

If it's a pressurised system, check system pressure and top-up if necessary.

If not or if system pressure is fine, then the bleed points could be blocked. Turn off both radiator valves, remove bleed nipple and insert a pin into the radiator to clear blockage - replace nipple open valves and bleed as normal.

thankyou for your reply, but im not sure how to check if the pressure is ok, and how to top up if necessary, thankyou.
