Hi Folks,

I've recently bought a house and need to move two radiators before moving
in, the central heating system is run of a Worcester Bosch 24CDi BF combi
boiler (sealed primary system).

So my question is this, when I want to drain the system, do I simply shut
off the boiler (on the control panel and at the supply), open the drain cock
and the radiator air vent until water stops?

Conversely when I have moved the radiators do I simply reverse the procedure
and fill the system (using the filling key) until the gauge indicates
0.5bar?

Hope someone can shed a little light on this subject.

Cheers

Jeff
