So I'm guessing you are wanting to know alternative ways of draining?

You could shut off both valves to a downstairs radiator, drain that rad and remove. Then place a tail of copper into each of the valves and attach some hosepipe to the copper tails leading to outside, and open the valves to drain.

If the radiators downstairs are all on drops, you will have to do this to each one individually.

Are you sure there are no combined lockshield/drain off valves anywhere?

Have a look around outside the house, sometimes the drain off has been
taken directly outside.

If no drain off then remove a radiator and drain directly from the rad valve.

When empty you can fit a drain cock for use in the future

You could get yourself one of those self-cutting washing machine water valves, and fit that as a drain off.

Once you have drained the system, remove the self-cutting valve, and the short secton of pipe it has mangled, and fit a proper draincock in it's place
