where

do you live?

There may be a local distributor that has them in stock. It would save on shipping costs.

trv alternative

there is one cheap alternative to trv's to reduce the radiator output: remounting the air vent so it leaves less room for steam, and more room for air. drill a new hole at the top of the radiator and tap it for the vent. plug the old hole. even more drastic, mount the vent at the valve end.

while you have the system off for this, prepare the "melting butter test" to see how much more quickly this rad heats up before the others. let the rads cool down and take identical pats of butter on identical plates, out of the fridge, and put 1 on this rad, and 2nd one on another elsewhere on the SAME floor[even better if close to the thermostat]. have someone else watching the butter melt. when each melts, call the other, and you will see how much different the speed of steam arrival is.

this difference can usually be evened out by increasing the main venting, so that you have no back-pressure in the mains until the main vents close, and begin forcing steam up the risers. on the top floor all the rad vents should be the same, so the steam arrives all at the same time.

remember you can get 3 gorton #2's for the price of 1 trv! i have 54 rads and no trv's and now have pretty even heat, as a result of putting 2 gorton #2's on each dry return. low pressure [12 oz.] also helps keep the system honest.--nbc
