Is this my filling loop?

[Kevine]

Hi, I need to drain my system after running cleaning fluid into the system a few weeks ago.

I have a Greenstar 24i boiler that has no filling loop, so I need to find where the mains water is getting into the system. Looking at the picture that I've attached appears to be the filling loop. Do I simply use this to refill the system once drained?

Secondly it appears I have no drain off cock anywhere... So I'm thinking to take off a radiator at the lowest point and hook up a hose to one of the valves and drain there or is there a better method?

Many thanks!!
