steam vent releasing too much steam into room

The radiator in my apartment bedroom releases too much steam from the steam vent causing steam to condense in the bedroom, the steam vent position was on 1/2, however moved it to the fully closed position, last time it was on it hissed a little and released some water rivulets but no steam, is this a correct maneuver? or should it stay open ? can anyone help? Thanks

    Vent needs replacing

    The vent should pass NO steam, never mind too much.

    The vent is designed to release air ahead of steam then close when the internals are heated by steam. When the radiator cools, the vent opens to release the vacuum to let the condensed steam back out.

    It could be that the system is run on too much pressure. Venting should be a silent affair. If the system is run at too high a pressure, vents failures accellerate and the spitting issue is exacerbated.

    Too much steam from radiator?

    I have one radiator that seems to put out too much steam when the house heats up (from the radiator relief valve). It was never this bad before but after 10 years it is starting to warp the furniture around it.Is this a simple fix or does something need to be replaced?

    Could this be as simple as closing down the main vale to the radiator, by closing down I mean just cracking the valve a bit to stay open without closing off the entire radiator?

    Steammmmmmy heating

    A properly functioning system will never release steam into the room. When steam is lost, the boiler must be refilled too often, introducing too much fresh oxygenated water into it shortening its life drastically., as well as causing the other humidity problems you mention, (along with mould).

    Replace the radiator vent with a good quality Hoffman or Gorton, not one from the big box store. Check the pressure the system is reaching, and adjust the pressuretrol to below 2 psi, or lower.

    If you have any more questions, start a new thread, so as not to get lost in this one.--NBC
