Flushing micro bore central heating

[mickfos]

please help,
Ihave a noisy Baxi 105e ( whining loudly when cold and a lesser whine when running ) this throughout the whole central heating system.
I have a central heating system that has 8mm micro bore and have been advised to have it flushed, as I have a noisy boiler/system.
Can I do this myself and if so what is involved, or do I need a profesional
to do it.
If I need a pro what cost can I expect for a 3 bed house, with rads in each room.

thankyou Mickfos

Dont powerflush if you have twin entry rad valves.

DS40 it.

AND...it wont melt!

what is DS40 ? And would a powerflush really melt a microbore system ?
