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 ceili ng is currently down). The exit points are are at socket height (behind whe re the radiator would be) so I would just cap off the pipes in a back box a nd cover them with a blanking plate.
Once my project is complete there will be limited access to the ceiling spa ce so I was planning on connecting all the radiator feeds up to the ma nifolds now hence the unused ones will likely be sitting there for a long t ime with either air or water in them. Does anyone anticipate any potential issue(s) with this?
