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

Comments about Thermostatic Rad Valve w/ Vac Breaker (1 Pipe Steam):
Purchased two of these TRVs to install on radiators that I couldn't control with various radiator vents. The radiator vents would either allow too much or not enough steam.Installed these and the radiators/room temperatures are controlled exactly where I want them.MUST have vacuum breaker on one pipe steam system to function properly.
Bottom Line Yes, I would recommend this to a friend

When combined with the thermostat, this works great. It really helps to regulate the heat coming from the radiator. I no longer have to suffer in a super hot room or sleep with windows open. Strongly recommend!
Best ting since slicded bread
from Turners Falls, MA
After 30 years of trying to regulate my heat in my house this is the answer to my problem. I had tried using two thermostats and shutting one radiator off or having one room 5 degrees higher than the other. Now with this I don't even have to think about manipulating the radiators any more. Now I'm planning on getting more for the upstairs. I highly recommend this product. I've been asking local suppliers for years and none seemed to know of a way to regulate one pipe systems. I'm glad I found this online.
No more 90 degree second floor
from Providence Rhode Island
Installed four of these in the second floor of my house, before installing we would have a 90 degree second floor and a 60 degree first floor with a gas bill that was out of this word. albeit winter has yet to really hit us but I can already tell you that these were worth every dollar, we now have a comfortable first floor and a controllable second. note that all of the way turned to minus (coldest) you get just enough heat to take the chill out of the air, just the way we want. I'm confident our gas bill will be much lower this year. A must of old steam heat homes.

Radiator steam control that works.
from Washington DC
The three-part Danfoss steam valve, operator, and vent control the "too hot" and "too cold" radiator complaints. Easy to install.
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.
