Replace the plug, open the valves to let water back in, and bleed out the air.
Run the heating for a few days, then turn off the mains water inlet (in the airing cupboard , or even the house main) open bleed screws on all rads and drain the system using a hosepipe into a drain outside.
Once empty, turn the water back on and bleed all the rads (starting downstairs )
Sounds daunting, but it's easy enough.
