Removing a Microbore radiator

We are unfortunate enough to have a microbore central heating system. For a plumbing simpleton like myself this complex system serves up a few headaches when I need to remove radiators for decorating. Microbore is supposed to be quite an efficient system that reduces heat loss through pipework but it also lends itself to pipe clogging because the pipes are typically only 8 or 10mm in diameter. I’ve posed a question on the DIYnot.com ‘microbore heating’ forum (under the alias of ‘funkydung’. If anybody else is in the same position as me, or has the answers, I’m keen to know exactly how one might remove radiators from a microbore system in order to do some decorating.
