Draining a central heating system

[jmcclintock77]

Hi,

I have a condensing boiler with an unvented water tank in the airing cupbord. I want to change a few radiators and fit a new bathroom. Can I drain the system like you'd drain a combi boiler system? If I can, how do i repressurise the system when I fill it back up with water?

Regards

James
