I had lots of issues with trapped air in my rads, these vents work, and prevent the need for regular bleeding.
This is a straightforward replacement for the standard vent valve. It works well, although it protrudes a bit further than the normal vent.
Price was good and perfect replacement that had been on for 30 odd years
got rid of a load of hot air at a turn of a screw
My towel radiators required frequent bleeding. These vents solved the problem. Bought this one as a direct replacement for one that was fitted fifteen years ago so they do last.
This is for the end of radiatiors, it isnt automatic
Good solution for that rad in everyones house that always need bleeding, once the washers /valve inside was wet it didn't leak at all. I've not had to bleed it since. Cheap and easy to fit
Air vents working as expected and service by staff excellent.
Does what it is supposed to do.
Bought these as a possible fix to sir in a swimming pool solar system. Fitted work a treat.
