Tado with Radiators and underfloor heating

Bosis

Hi. 

I wonder if someone could help me to make the right decision please.

We have a new underfloor system in an open space Livingroom / Kitchen in a L-shape. The builder put 2 zones in the kitchen are ( one end of the imaginable L-shape ), one zone in the middle where the main Livingroom area is and one zone at the other end of the L-Shape area, where the dining area is, plus it goes over in a nearby small utility / toilet. ( see image )

At the moment we use upstairs radiators tado valves, and we have bought but not installed yet a Tado Starter Kit Wireless Smart Thermostat, to control the Worcester Bosh boiler, and one wired Smart Thermostat for the underfloor heating. 

The whole space is not huge, maybe 8x4m one direction an 8 x3.4 m the other.

I wonder how we can control it best via Tado and how many Tado wired Thermostats are useful, as I could just install them quite close together ( like around the corner with 1 m each from the corner ), maybe with new wiring one direct in the kitchen area and one in the Livingroom/dining room area

Somehow it feels that max two Thermostats would make the most sense, and to turn the existing pump for the underfloor heating with those on or off in addition.

( At the moment we do not have any electrical actuators installed , just manual controlled)

For example a heatmiser 4 zone with 4 actuators installed. Could I get each 2 Actuators controlled by 1 Tado wired smart Thermostat,

I would like to turn the underfloor heating off when a max temp reached and/or over night incl. controlling the underfloor heating pump.

When possible I would appreciate a wiring explanation too please, and what you would recommend to install. 

At the moment I am looking at the heatmiser UH4 and the Danfoss 088H3220 230V NC.

Our Worcester Bosh boiler is in the loft and the underfloor downstairs. Do I need wiring up to the boiler to control them, even when I use the tado wireless smart thermostat? 

Does this make sense or what are your thoughts please?

Thank you in advance for your help.

I'd keep it simple and use your one wired tado sensor to control all three underfloor pads. I can't comment on the wiring but this should be possible. I'm not sure you'd need anything else like your other wireless sensor if that wired sensor for your underfloor can be located on a wall say 1.3m out of the drafts and set at your preferred ambient temperature.
