Heating help, Nest upgrade

[jimboy2]

I want to upgrade my heating system to Nest or Hive.

I hate heating systems so I have taken some pictures of what i have.

 

Wireless thermostat

 

Reviewer for thermostat

 

Timer and timer connections and wiring diagram.

 

 

Will this be a straight forward upgrade? The thermostat receiver is in the loft with the boiler. The time is on ground floor

 

Thanks!

I did a load of research and I opted for NEST. Yes it's fairly simple to install for a competent DIYer.

I installed my Nest about 3 weeks ago. Looking at your system above it should be pretty straightforward. You will have to make up a couple of short links to go from the incoming 240v to the hub ( original controller) to each switch of the hub ( heat on and water on).

It'll make more sense when you start to install but it is easy to do.

So is the nest going to replace my timer in the hallway? Or will It be replacing the receiver in the loft with the Nest heat link?

It would be able to be installed in either position as the wires from the timer will run back to the boiler in the loft. It would be more work to trace out which wire is which up there. The easier option would be to remove the timer in the hall and mount the heat link there.

Your choice really. If you weren't so far away I would've helped you.

The main "white" heat link nest box replaces your old controller. The sexy multicoloured round thing can go in place of your stat. But as you have a wireless one already. I would suggest buying the optional stand as well and plugging it in somewhere (it comes with plug and lead)
