Nest installation and setup

Heat link

Install Google Nest It is not too complicated if you are a handyman. The purchase package includes both Google Nest and a connection box called Heat Link, that is, the link or interface to connect the Nest thermostat to your home's air conditioning system.

And by the way, Google has created an extensive network of official installers who do everything themselves for about € 90 if you don't know. However, if you know what you are doing, you can choose to proceed on your own and follow the steps below.

Once the package arrives and you take it out of the box, the steps to follow for installation are:

  1. Connect the Nest Thermostat to the Heat Link. You can do it wirelessly or through a couple of cables. The ideal is the first to save you the cables and to be able to place the Heat Link next to the boiler thermostat (or in replacement of it) and the Nest thermostat in the living room or main room. Also included in the kit is a 5v USB power adapter for the thermostat.
  2. Both the Nest Thermostat and the Heat Link are ready to screw them to the wall if you prefer. They can also be put on a desktop stand (sold separately) or wherever you want.
  3. Turn off your boiler and cut the light to manipulate the cables (it will avoid accidents with discharges). You old boiler thermostat it should have two cables (there could be others where there are more cables). To connect it, follow the guide where he explains all the cases. And is that the Heat Link has several connection ports to adapt to all types of boilers, so you must follow the steps for your specific case.
  4. Once the cables are connected, you can close the lid of the Heat Link and give the light of home again. Also turn on the boiler.
  5. Now turn on the Nest thermostat and the screen will turn on to start configuring it by following the software wizard that is very simple. In the end, in 15 or 30 min you will have it ready. By the way, Nest has a battery, so if it's charged you can take it to other rooms ...

  9. If you want, at any time you can configure information displayed on the screen. For example, if you don't want it to show the temperature, you can configure it to show a digital clock or imitate an analog one, and even the weather forecast ...


As I have commented, it is not a simple thermostat. Have more capacities than you imagine. Among its most outstanding functions are:
  • Thermostat: you can vary the desired temperature of a room, turn the heating off or on when it reaches a suitable temperature, turn the system back on if the temperature is no longer set, program various temperatures depending on the day, etc.
  • Financial: learn from habits to create a personalized schedule. Recognize the preferences of each home, based on how you interact with the thermostat to adjust the temperature without your intervention. You will generate a temperature schedule and understand the heating and cooling cycles after the first few days of use to become more efficient.
  • Connectivity: through the mobile app you can interact with it from wherever you are. Even from any other computer with a web browser.
  • Sensors: if it does not detect presence at home, then it will lower the temperature to save.
  • Ecosystem: There are many other products compatible with the Nest thermostat to continue domotizing your home and extend its capabilities. For example, with the Phillips Hue light bulb, Whirlpool appliances, surveillance cameras for security (both indoor and outdoor), etc. For example, you could install security cameras and see what happens from the Nest app itself.

Is the Nest Thermostat worth it?

The question that you may be asking yourself that cannot be answered in a too direct way. Everything it will depend on your needs. But to make it a bit easier for you, here are some possible cases:
  • You have a somewhat older heating system with a basic thermostat or this thermostat has broken. In that case, a Nest thermostat can replace your traditional thermostat and make things easier for you and bring much more efficiency, reducing your electricity bill. Therefore, this would be the case in which it is most worthwhile.
  • If you already have a programmable thermostat, then it is no longer so clear that the Nest thermostat is so worth it. On the one hand, the energy savings you can achieve with the Nest is minimal, although it is somewhat more ECO. But it is true that with the programmable thermostat you will not have the extra capabilities that a Nest provides. For example, the possibility of controlling it from the mobile app, or the use of home automation devices compatible with the ecosystem ...
  • You already have a home automation with a smart thermostat, then the truth is that it is not worth having a Nest. It won't bring too many improvements in comfort or efficiency ...
