Apologies for the rather cryptic title...

I am in the middle of creating an open-plan kitchen/lounge/dining area and cannot with certainty decide where best to put the radiators. Indeed, I can envisage that the 'best' position might well change over time if/when the more mobile elements of the room move around.

I was wondering, therefore, if there would be any issue with me piping up a couple of areas to cater for the potential alternative siting of radiators at a later date? In keeping with the rest of the system I'll be using 10mm plastic piping run down from the ceiling behind the plasterboard so it'll be a straightforward job to do at this stage of the construction (the ceiling is currently down). The exit points are are at socket height (behind where the radiator would be) so I would just cap off the pipes in a back box and cover them with a blanking plate.

Once my project is complete there will be limited access to the ceiling space so I was planning on connecting all the radiator feeds up to the manifolds now hence the unused ones will likely be sitting there for a long time with either air or water in them. Does anyone anticipate any potential issue(s) with this?

The unused legs would be better filled with water rather than air. How
about connecting each flow and return together through an isolator valve
behind the blanking plate? You could then allow them to fill with water
and then turn off the valves.
