So. My living room radiator acting wired. It have two valves one on each side (no trv) we use to open and close one valve in order to get more or less heat. Accidently some one touch the other valve (the one you not spouse to touch) and from than the radiator become colder. It is still warm but not burning as it uses to be before. I try to play with it but I cant get it to work as it was I was thinking that if both sides are open all the way it should give you to most high heat. What am I doing rung? Do I need to close the out valve to create a pressure in the radiator in order to get more heat? or do I need to open them both all the way in order to get more heat I want that radiator to be on full blast. Thanks for the help.
