If the heating is on then I don't understand why you turn the cold water off - if the house is warm, the pipes wont freeze.
The only reason you would have been told not to do it - is because if the water is turned off - and the hot water tap is opened then there's no water in the DHW section of the boiler the next time the CH comes on
