3 zone smart thermostat

And one of those zones isn't controlled by a thermostat?

I believe both are using the same thermostat

Which as I said before is effectively one zone if they both switch on and off with the same thermostat. You can do the same or add another stat for much better control.

So just power needed for the thermostats or are these battery?

The Wiser system has it's own wiring centre so all the wiring would need to be checked for suitability.

So it uses existing wiring? Not wireless?

Yes Wiser is wireless, but still needs the receiver wiring in. It appears the Tado does have the option of being a 3 channel.
