    you can drain it from one of your lowest rads then fit a draincock at the same time.

    if you want to be there alday.
    otherwise from one of the radiator valve.
    shut both the valves on a rad that you wish to fit the draincock and drain the rad then when the rads drained you can undo the rad valve from the rad and drain the system.
    theres a few different ways to go about it.

    get yourself a bowl or tray (paint tray) that will fit under the rad valve.
    shut both rad valves, then slacken the nut between the valve and the rad and that will drain the rad.

    uncouple the rad, drain it.

    Fit hose to rad valve, drain CH system

    Cut pipe going to rad and fit a t piece with a drain off it.

    Change cylinder.

    Although, by you lack on knowhow I might recommend getting in a plumber....does house insurance cover DIY disasters???
