I installed my first Nest system today and thought id share my experience.
I installed two, nest third generation room stats, their not cheap at around £200 each. The reason i installed them is for a disabled person, this way they can turn on the heating without clambering into a wheelchair.
The system was a dual zone combi and each zone needs:
Heat Link- fancy way of saying receiver for the new room-stat to communicate with the original wiring, its the white box in the photo with two flexes going in to it.
The Thermostat- This can be placed anywhere but if you use the original room-stat/position this can be used to power the new room-stat but its 12v so it needs to be connected to the relay inside the heat link. Or you can put in anywhere but then you need to use a plug to power it, which looks naff and you then have to purchase a stand and all that.
You could install it fairly quickly with a single zone system but if you have a dual zone system its a ballache as the wiring centre needs heavy modification. There is also very limited and poor wiring diagrams out there which are catered towards single zone systems, the destructions are pretty poor on the wiring side, so a decent working knowledge of heating systems is needed. I just made my own diagram up in my head.If you mess up the wiring and dont properly connect it you can blow the roomstat as its 12v dc.
The previous install was a bit messy and rough so i removed the small junction box and fitted a Time guard Central heating box-which was top notch and will be bought again! i also rewired the boiler as the flex was damaged by the previous monkey.
All in all after the wiring and the tight cramped HOT cupboard side of the job(im 6,2") the rest is really easy. The setup of the wireless network aswell as the online account is simple and intuitive. I will fit them again but will price in a day for the job i reckon.
