Vent offset on open vented cylinder

[Dannyparty92]

Hello everybody. Could somebody please tell me why it is necessary to offset the vent pipe by 450mm directly off the top of an open vented cylinder. Iv heard its to "prevent one pipe circulation" what exactly does that mean? Thank you.

What do you mean offset the vent pipe?

Well as soon as the hot pipe leaves the top of the cylinder you have to elbow it you can't run the pipe straight up from the cylinder to loft.

i heard daniel day lewis finds it hard to work with some actors. But rather than moan about them while at work he preferes to " vent offset"

Something to do with cylinder constantly heating and filling, i think

Because heat rises. Heat will travel upwards then get cold then more heat will rise then get cold then more heat will rise then get cold then more heat will rise then get cold then more heat will rise then get cold......
