First, i must say that i thoroughly research EVERY product i buy... i like to see a return on my investment..so yes, i thought twice before forking out the money for these valves...but i'm glad i did....i have a 3000 heated sqft. 3floor, 120 year old home in Northern NJ. i am 12 years in house with 9 years using Danfoss thermostatic valves.i have 14 radiators on 3floors...5(1stfloor) 6(2nd floor) & 3(3rd floor).11 of these radiators have Danfoss Valves..i swear by these valves.... yes i know they aren't "cheap",but trust me, you will recover your money because you will see a dramatic decrease in your utility bill. it allows you to control heat in unused rooms. it can be 20degrees outside and my boiler is only pushing steam into a few of my rads.. NOT all 14 of them. MY ONLY WARNING is this: the Danfoss Valve is NOT meant to be inside an enclosure(radiator cover)...it will cause a false temp reading. Sooo, if you use a Danfoss valve make sure you have it exposed so it can read the ROOM TEMP, not the temp inside the rad enclosure.if you have steam heat, i highly recommend these valves... it will keep you from heating rooms you dont use or allow each person to keep the room as warm or cold as he wants...Don't let the cost scare you from buying them... Try ONE valve...trust me, you will buy more...

Produces horrible high-pitched whistle
We have both this model and the Honeywell Braukmann (without the vac breaker). The Honeywell works just fine; while this one also performs acceptably, it emits a high-pitched whistling that drives us...Read complete review

Radiator steam control that works.
from Washington DC
Comments about Thermostatic Rad Valve w/ Vac Breaker (1 Pipe Steam):
The three-part Danfoss steam valve, operator, and vent control the "too hot" and "too cold" radiator complaints. Easy to install.
Bottom Line Yes, I would recommend this to a friend

Great way to cool down hot rooms
from Long Island, NY
I have a two story colonial with 3 bedrooms that vary greatly in size. I originally used vari-valves to try to control the heat and they worked, but the rooms always still received heat during each boiler cycle.Since i changed to this product i see a huge difference. My wife likes to sleep in a cold room, so we keep the dial turned way down. It's better than turning the valve off complately because if the temp drops below 64, the heat will come on in the next cycle.It works great too for my sons small bedroom, where the ambient heat from downstairs keeps his room warm enough on it's own.Overall, it seems a bit pricey per room, but in the long run, the comfort is worth it. We're probably saving a bit to on heating costs since my wife no longer opens the windows in the middle of the night.
thermostatic vent tames hot rads
By living large in Cleveland
The polar votrex was kicking my butt this winter causing my 2nd floor steam rads to run hot as heck. installed a couple of thermostatic air vents with operators that have remote sensors (the rads have covers) & the 2nd floor temps are now the same as the 1st floor. These units are long so you have to make accommodations if you have covers on your radiators like I do. Worth every penny & then some.
Work as stated!!
from Bogota, NJ
My son wanted these for Christmas. OK - a little weird - but that's what he wanted! He and my daughter in law rave about how well they work!! They finally have even heat in their steam-heated house.

No more spitting !
By Dave from Millerton
from Millerton, NY
Thanks to the vacuum breaker, this valve finally stopped my one pipe steam radiator from spitting. Works fine. You also need the direct mount operator and steam air vent. Assembly is very easy.
Works perfect on one pipe steam system
I installed these in all three upstairs bedrooms to keep the rooms from getting too warm. I tried Honeywell but they lack a vacuum breaker so the radiators would accumulate water and spit it from the vents. I tried Macon and while they have a vacuum breaker, the low pressure of my system couldn't activate it so the result was again radiators accumulating water and spitting it from the vents.Then I tried these Danfoss TRV's. They work perfect. The vacuum breaker works perfectly and is activated with only an infinitesimal amount of vacuum pressure. Our radiators are staying dry, vents aren't spitting water, and all bedrooms are staying cool just like I wanted.I could have saved myself hundreds of dollars by choosing these TRV's in the first place.
