Help! moving from Nest Y plan to Tado PDHW (X Plan)

Options

Hi All,

We're currently undergoing an extension, and I'm planning to switch our heating control from a Nest system on a Y Plan to a Tado system on an X Plan (Priority Domestic Hot Water - PDHW), including the integration of Underfloor Heating (UFH).

Could you advise on the specific Tado equipment required for this transition? Additionally, I'd appreciate guidance on the optimal setup.

I've attached the current plans and my proposed layout post-Christmas for your reference.

Thank you,
