Tado and Zone Valves
Hello folks.
I'm stuck on what to tell my plumber and electrician to do, I really hope you can help! I'm in England if that helps.
I'm renovating a property and putting in a new GCH Ideal combi boiler and rads with all new pipe work.
I've bought Tado wired thermostats, 3 in total, to have 3 heating zones. I've bought Smart rad valves but now here's the bit I'm stuck. What do the thermostats wire in to? Do they need a zone valve per thermostat?
I chose Tado rather than Nest as I didn't want 3 sets of pipes to go with 3 zone valves. My plumber said with Nest you need a circuit (pipes to boiler) per zone valve. I was hoping with Tado I could just add it to my central heating system instead of adding another heating circuit.
I just need to say to plumber and electrician you need to do this, this and this!
or I could just install the wireless?
Please help :-)
Thank you

Tell them you want an S Plan Plus system for three separate heating zones. The Tado thermostats are programmable so you don't need a separate programmer. The thermostats are battery powered and don't require a Neutral - just Live and Switched Live. For the radiators you want TRVs fitted with an M30 x 1.5mm thread so you don't need to use an adapter when attaching the Tado heads.
You will need three water circuits. You'll have a single outgoing pipe from the boiler that divides into 3 pipes. Each of these pipes goes into a zone valve to give you 3 temperature controlled circuits.

Alternatively don’t use zone valves at all and just use a wireless receiver and put tado trvs on your radiators. You can effectively create virtual zones with the app by defining rooms.
If you’ve got a big house, there may be connection issues due to Tado’s limitation of having a single bridge.0 -
@Pauldiy Building regs require two heating zones for properties over 150 sqm. Usually that means extra expense with multiple zone valves, multiple wired stats, and two pipe runs for rads. With Tado you get to control up to ten zones with up to 25 devices.
I’d agree with Johnny. With a combi boiler, use the Tado system (wireless stat/receiver and TRVs) to create the zones you require, and comply with building regs. No zone valves to seize or motors to fail, less complicated plumbing, less wiring. Should save £££ on the install.
The limitation is where you have a big house: the number of room (zones), distances from trv to receiver, etc. We still use one manual trv for a room rad too far from the bridge to be reliable, and two rooms with Tado trvs set as independent.
