Vertical Radiator Connections - is BBOE same as TTOE ???

[timtimmo]

Hi to all,

Newbie on this forum and need some help on this ..... trawled the web for hours trying to find an answer!!!!

Anyway, Mrs wants these fancy vertical rads and I can save myself a bundle of work if I mount the flow and return connections at the top for the downstairs radiators.

I intend to use a Drayton TRV4 & conventional locksheild and according to my school boy physics, this is the same as a conventional BBOE (Bottom Bottom opposite Ends) connection used by every man and his dog.

Given that hot water rises etc... only downside might be a cooler radiator at the bottom but the convection water circulation action should be the same? - or am I being a complete numpty!

Any help much appreciated good people.

You are not too bothered about heating the room then.

Come on Bacho - Don't leave me hanging!! What is the gem of information behind your comment.

I am ready to be officially labelled a numpty!

hot water rises.

If your flow of hot water goes into the bottom of a rad, it will rise up and fill the top.

If it goes in at the top and out at the bottom, it will push the cold water out and fill the rad with hot water.

If it goes in at the top, and out at the top of the other side, it will not spread downwards, so all but the top inch of your rad will be cold.

OK

You are a numpty.

The most important thing to remember is the amount of work it will save you

Well, it works fine on a Towel Rail in my house...ladder style one about 4 foot tall Try putting a 10mm copper tube down inside the flow side ..like the double entry microbore rad valves used to .that`s only an idea............before all the corgi`s start barking

Thanks guys,

Really appreciate the feedback - guess I am off the on wrong track but it still intrigues me how a BBOE works given the explanation of hot water rising by by JohnD

The inverse must be true - cold water falls - hence the circulation action.

Many thanks once again - time to chase those walls!

Fitted a towel rail with top entry/exit pipes.

Soldered a lengtth of copper to the inside of a rad insert and put it on the return.

Works a blooming treat.

Blah,Blah,Blah
Of course you did Dan
Why don't you scan your qualifications so we can marvel at your experience
ps.......it's flow and return pipes
exit is what you will see in cinemas while watching cowboy films
