Radiator Thermostats
I am looking to add thermostats to each of my upstairs radiators. Has anyone done this and if so, what thermostats have worked for you?

I guess I would be seperating the zones. Each radiator would have its own t-stat located where the valve is currently. Thus, each room would be its own zone. I currently have only one t-stat located on the first floor of the house, which does not allow for any zoning, creating a huge temperature difference between the first floor and the second. I know that Honeywell UK makes all sorts radiator t-stats, but I have not been able to locate any stateside. I am hoping that someone has installed these before and can provide me with some guidance.

Trv
Yes yes... I know exactly what you mean - good choice. I've never installed one but I'm sure other here have. I want to put one or two in downstairs when I get a chance and an old CI rad or 2...

Does your system have any flo-control valves on it ?
If not, maybe the upstairs is overheating due to thermo-siphon (gravity) flow.
I'm assuming this is a converted steam system ? (to hot water)
It might be cheaper and easier to add just the flo-control at one point near the boiler, rather than drop the bucks for all them TRV's ...
Check out www.patriot-supply.com and look for TRV (thermostatic radiator valve) if you decide to go that route. They also have the flo-control valves.

My system does have flow control Ts, but to the best of my knowledge, there are no valves. The system has always been a hot water system, though at one time it was a gravity system. The expansion tank was welded shut and moved to the basement sometime in the 1920's. Thanks for the link. I have my plumber coming to visit in the next few weeks so he and I will check it out further.

By flo-control tees, I'm assuming you mean the venturi type of tee...
When you say "welded shut" ... I guess you mean the tank that was probably originally in the attic, when it was an "open" system, way back when ?
Does your plumber know about heating systems ? some do, some don't...

just done it myself.
1. drain system, hosepipe
2.take of old valves (careful not to damage threads)
3. fit trv one one side and lockshield on other.
4.leave one rad without a trv ! two lockshields ! must do to allow flow always.
5. fill up system steadily bleeding out air on fillup. do it steady to prevent airlock.
boiler off allway through !!
set trvs lowest nr to boiler and wrk away so furthest is set highest

Great info Adamwakfield,
What tvrs did you use? I have not found any in the area and most local plumbers are rather dumbfounded by my questions regarding tvrs. Also, the only information I have found on tvrs is in relation to steam boilers. I assume that since you bled your's that your system is water. Finally, why are these valves not called trv's, the acronym would make more sense?

Any good plumbing and heating supply house should have them. Maybe contact Danfoss and see who represents them in your area. Then call the wholesaler and find out who sells them locally.

You are correct any good plumbing supply houses should have them. Unfortunately, is appears the I do not have any good ones in my neck of the woods. I did just receive the information from Danfoss and am looking over it right now.
