Yes, and would be annoying to operate, too. I think I'll just have to
do the Right Thing.

Without looking at the route for the flow and return pipes to the indirect
coil I can say how easy this is for you. Plastic pipe, used wisely and
correctly, will greatly simplify the running of pipes in suspended floors
and/or ducts.

If only I had any suspended floors or ducts! Alas my apartment block is
built like a car park - concrete everywhere! Plus the flat layout is
against me - the boiler in one corner, and the HWC in the far opposite
corner, separated by doorways and corridors. Even to get the pipework
from one side to the other will require going up into the suspended
ceiling - which will require some carefully placed air vents.
