Tado with floor heating plus radiators

Options

Currently I have the following setup:

* Downstairs: Wired Smart Thermostat with 4 radiators. Radiators have taps (not thermostatic valves)

* Other rooms: Tado TRV knob in each room radiator.


I'm planning to upgrade the heating system as follows:

* Downstairs: Wired Smart Thermostat with 3 radiators. Each radiator will get a thermostatic valve and a Tado TRV.

* Also Downstairs: Underfloor heating with 6 groups. I want to control this with Tado.

* Other rooms: Tado TRV knob in each room radiator. (no change)


What I want to do:

* Independently control different rooms.

* Because underfloor heating can take a lot of time to warm up, use few radiators downstairs as additional heating.

I'm not an expert - but I thought it may be a good idea to keep a few radiators downstairs in case the quality of insulation under the concrete is uncertain.


Questions:

* What are the additional Tado devices I need to purchase? Is it only a Wireless Extension Kit?

* I've seen some pictures where people connected TRVs to the distributor pomp. Is this a safe setup?


Thank you in advance!
