Positioning of manifold for UFH?

I am having an orangery built and it has been suggested to have a Prowarm high output water underfloor heating system installed. The boiler is in the garage and is a distance away from the orangery. I have an airing cupboard in the landing where the megaflo, heating pump, and zone valves are located.

I have a bedroom nearby the airing cupboard on the first floor which is 6-7 metres away from the airing cupboard. This bedroom contains a small cupboard. It has been suggested by a few plumbers to run 22mn pipes from the return & flow in the airing cupboard to this small cupboard where the manifold for the UFH can be positioned. From this manifold, a hole can be punched out of the wall in this small cupboard and the UFH pipes run down the wall down into the new orangery.

This drop is about 2.5 metres. However, I have had a UFH installer who does not recommend having the manifold on the first floor with the UFH pipes running down the wall. He thinks there will be problems later on with the flow and discourages from having 90 degrees bends which he says is likely when the manifold is on the first floor.

Does anyone see any issues with having the manifold on the first floor and the UFH pipes running down the wall into the orangery?
