I have a couple of these throughout my home, on the 1st and 2nd floor. The radiators get heat but quickly disapate.

Should these be replaced? I don't exactly know how these work. I have one in a bathroom that does not get heat at all, but I confirm heat is able to come from the inlet. We have a two pipe system.

    There isn't much that can go wrong with those things… provided all the parts are still there.

    HOWEVER

    There is one thing that can go wrong: excess operating pressure. Anything over about 6 to 7 OUNCES per square inch is too much, and may prevent some radiators from heating.

    Two other possible reasons for a specific radiator not heating are that something is amiss with the trap elbow on the outlet side and it is unable to vent or drain — stuck closed — or that someone closed the inlet valve. Check the valve first… remembering that clockwise is closed.

    or someone replaced the vapor valve on another radiator with a standard valve. or various knuckleheading at the boiler.
