Worcester Bosch greenstar boiler?

By opening the drain off, small brass thing normally on the outside of your property some where, to realease some water. Or a little longer way is to take the water out of your radiator via the way you normally bleed the radiator for air, have a bowl or something to rain the water into, but remember to switch your boiler off while doing it.
