I live in a house that is 3 years old with an open vented central
heating system.

I am trying to remove a radiator and was looking for the option of not
draining down the system completely.

I was going to use bungs in the feed and vent pipe. When I looked at
the expansion tank there appears to be no vent pipe hanging over the
tank.. The boiler supports a combined a feed vent option but looking on
the internet this looks to be an out of date practice.

Is it still possible to bung the single pipe as you would with the
separate pipes and so not drain the system?

if its only the rad why not turn off both valves and then just drain the
water from one side of the rad by 'cracking' the joint and opening the
bleed valve, use a roasting dish or like to contain water and wrap an
old towel around the bottom of pipe and on the floor to save carpet etc
