The radiator in one of my bedrooms was oversized because the room didnt get sun. This radiator placement is from  1926.

The room gets too hot! Aside from a thermostatic valve and changing the radiator,

what other options?

Thanks, Happy new year to all.

    Hi Irv- I'm assuming this is one pipe steam as with two pipe you could just throttle the inlet valve.

    You might try a different air vent like an adjustable Ventrite #1.

    You could put a small ball valve between the radiator and air vent and choke it down.

    I use a TRV and would recommend this approach.  I have a bedroom that gets too hot from be exposed to sun all day long in winter but as soon as the sun goes down, the room temperature plummets. The TRV evens the temperature out beautifully. I use to use a Ventrite but got tired of having to turn it up and down each day. I'm a TRV fan. I use them in "problem" rooms like yours  and also use them to shut down sections of my house during the winter which saves on my fuel bill.

    You might build an inefficient cover for it.  Even a blanket thrown over part or all of it will reduce the output on days when it's too hot. In one room I don't use too much, I installed a Watts adjustable air vent, and rotated the adjustment cap so that the vent hole is completely covered.  The radiator still gets hot, but slowly.

    Like Rod said, a Thermostatic Radiator Vent would probably be your best option, albeit a blanket is cheaper..
