UFH v3 addon using radiator thermostats

Hi all,

We have a good setup of a pellet boiler supplying a water tank using 3-way valve, the other circuits supply. We have had Tado running good for us in many years.

The pellet boiler may be replaced by a air-water heatpump or by a new pellet boiler, in a few years.

1) 8 radiators in 7 rooms on 2 floors - all on v3 Smart Radiator Thermostat with one wireless temperature sensor in one room.

2) UFH on ground floor on local themostats with remote sensor (not connected)

3) UFH on 1st floor supplied through the shunt manifold with separate pump in the picture below. There is two wireless sensors with dial for temp, it's an old 833 MHz system which does not work on one of the circuits and a replacement that might work costs €200 or more.

We would like to change it to Tado controlled system instead. Can I just use 2 smart radiator thermostats and 2 wireless temperature sensors added to the system?

I would like have the pump turned off when there is no need for heating but it is a low-energy model so it is not absolutely needed. I assume I need the Wireless Receiver for that?

Or am I better off converting the entire setup to the new X series? Given we are about to put the house on the market, that's a lot of money I would rather avoid spending,

Thank you for your help.

    Without knowing what specific heat pump you'll be using, impossible now to know what the X series and the new range of Tado products will bring to help you in the longer term.

    Suggestions:

    1. Dont use a Tado rad valve for the UFH manifold. They dont work well in that setting.
    2. Instead use a Tado wired thermostats to control one or more UFH loops, through the UFH wiring centre, determining which valves open and close. The wiring centre will then send a request to the UFH pump. You'll need that wiring centre to also open the UFH zone valve.
    3. If you need the triggers for those wired thermostats to be actually portable, it is possible in the app to set it up so that a wireless Tado temp sensor commands its respective WIRED thermostat.

    That clear? Need something else clarified?
