The hose should not be connected at all times, this is against water regulations. The hose should only be connected to re-pressurise the system. Also there should be a non-return valve on the heating side.
As for having use a hose, this is perfectly acceptable.
The mains cold water valve head has probably snapped off. This is not against any regulations but it would be easier if a new valve was fitted, but this is just for ease, not law or regulations.
Hope this helps
