Boiler in garage, which is only 'room' on ground floor apart from entryway and stairs. Flow and return pipes disappear into brickwork next to boiler, with half a dozen rads at first floor, and five at second floor with two rad-style towel rails. No sign of a manifold anywhere. The radiator pipework is "microbore", if I have my terminology correct, with the visible pipework leaving the boiler in 10mm copper.
We want to get a heater in the entryway, which has none at the moment, and reasoned between ourselves that without access to the manifold, we could not do this (prev thread in electrics - https://www.diynot.com/diy/threads/...-for-oil-filled-radiator.623750/#post-5653793)
Is it a realistic possibility to take tees off the 10mm to hook up a rad directly off the flow and return adjacent to the boiler, or does it really need to be done at the manifold? Is there likely to be expansion capability at the manifold, with perhaps our dozen or so rads fitted to a 15-way or 20-way manifold?
Also, where would the manifold be, most likely, since it's not visible in any utility cupboard? Under floor? Between the cavity wall brickwork? Would it routinely be between the two floor levels which have the existing radiators?
