Should I install it myself?
First of all installing the Thermostat involves mains voltage electrical connection unless you are both competent and confident doing this I would strongly recommend you employ a certified installer to do the install for you. Assuming you are happy doing this type of work the next thing you need to identify is what type of heating system you have. I would say that unless you are a plumber or electrician you should only consider installing yourself if you have a combi boiler or fancy the challenge of figuring out a maze of wiring!
I decided to install it myself mainly because I have underfloor heating and felt it could take a while to explain how this is set up to an installer. The install was very simple and took me about 45min. I opted to mount my Nest on the stand which you need to purchase separately, it costs an extra £29.
I found the configuration very quick and easy it takes you through the steps one by one. A few things you need to be aware of:
- During the install you are asked if you currently have a programmer, if you say yes you have to enter your program into the stat. I found this very awkward to do at the stat, I would suggest its much easier to set this up through the web portal.
- The Nest does not support 5Ghz wifi, this did not cause me much in the way of problems but I know others have had issues with interference from neighbours etc.
- The auto away function does not work until it has had time to learn your habits.
To be honest its to soon to make any but so far my first impressions are good. I will update once I have some more experience with it.
