Hot water ring pipe system

[Brenard]

I HAVE A LONG DEAD LEG ON MY HOT WATER SYSTEM. IT HAS BEEN SUGGESTED THAT I INSTALL A RING PIPE SYSTEM. HOW DO I DO THIS?
HOW DO I CONNECT THE RETURN TO THE DIRECT CYLINDER? DO I NEED A PUMP AND IF SO HOW DO I SIZE THIS? WHAT CONTROLS ARE NEEDED? ANY ADVICE WOULD BE APPRECIATED.

THERE IS NO SUCH THING AS A RING PIPE SYSTEM FREAKIN DEAF ARE WE

however should you mean secondary circulation it's no big deal
you need a flow and return to the furthest outlet and a "bronze pump"

you may well also need an essex flange fitted to the cylinder
