    Hi,

    I have problem with two radiators in the house. Basically all are roasting hot part from two that are lukewarm when gas CH on for a while

    I bled them and both seems to turned on fully.

    Any suggestions?

    Most likely a circulation or balancing issue?
    At a guess, are the two rads downstairs, one in that hall, the other in the living room the other side of the wall?

    Well used to them.
    You will also have the pipes coming out of the walls to the rads downstairs & out of the floors to the rads upstairs.

    Your boiler pressure will be reading 0.5bar.

    Basically, if yes to above, you have the dreaded drop down & most likely a semi-sealed system.

    If you boiler has any age to it, it most likely only has a 5m head pump. This in a highly restrictive system with 2 rads fed on a drop down 1/2" pipe in the wall is the issue.

    Can it be fixed? Yup.
