Any evohome gurus here?

I am looking at a system but dont think it is possable to do so need some guidance.

System boiler with unvented cylinder in loft space.
Every room downstairs has wet UFH over a 12 zone manifold.
Upstairs we have a traditional radiator system of a 'open' rad on the landing and one in each of 3 bedrooms. one in the main bathroom and one in the ensuite.
In the loft we have a pump and 3x 2 port zone valves (hw, ufh,radiators)
There is also a pump downstairs by the manifold.

Customer wants in the evohome system.......
Each room downstairs 8 zones beind independantly controlled.
3 rads in the bedroom each independantly controlled.

With the current setup i think.....

get rid of the 2 heating valves and put back to one and get rid of the pump by the manifold so its all on one loop.

then at the manifold use the 8 zone controller for all the downstairs rooms with stat in each room, use evo wireless trv's on all upstairs and a cylinder pack for the hw.

sound about right?

why would you get rid of the UFH valve and pump?

I gave you the answer on facebook! Yes this will work (the EvoHome bit - your plans to remove the UFH pump sound dubious!) but you need to have two controllers cascaded together to give you 24 available zones. Otherwise you won't have enough zones.

The app sees it as all one system because the base units, once cascaded, act as one unit.
