Nest Thermostat Review (3rd Generation) The Most Intelligent Thermostat?

Nest Thermostat ReviewIntroduction

Welcome to my Nest Thermostat review.

The third generation of this smart thermostat was launched in September 2015.

It comes with a larger screen which has better resolution than the previous version and it works with the Amazon Alexa system, which is a digital assistant that can be controlled with your voice.

It looks very sleek and stylish and Nest is now owned by Google which means that it comes with a huge reputation.

I have tried to write one of the most detailed reviews on this device that is available.

In order to help you, I have split it into sections. And so, just click on the section that you want to know more about.

Editors’ Pros & Cons

OK, if you are in a rush let me just cut to the chase and show you a list of pros and cons.

I created these after spending many  hours reviewing lots of smart thermostats.

Later in this post is a list of pros and cons that I have created from all the buyer reviews that I could find.

Basic Specifications

Smart Heating Features (1)

In the following two charts, I look at the features for this device that directly relate to heating and cooling.

[table id=246 /]

Programming

The Nest does not need to manually programmed as it “learns” from your needs.

During the first week that you have your device, if you just adjust the temperature on the thermostat as needs be, the Nest will then remember these settings and keep using them.

Compatibility

The nest is compatible with about 95% of all heating and cooling systems.

There is an easy to use compatibility wizard that you use.

You can find it here.

In order to use it, you need to uninstall your existing thermostat and then compare the wires that you have in your system.

Don’t panic, it is easier and quicker than it sounds.

Hot Water 

Unusually for a smart thermostat, it can control your hot water as well as your heating.

Humidifier

This device will connect to most humidifiers and dehumidifier systems.

Some systems have one wire to control the humidifier, other systems use two wires.

If you are unsure if your system is compatible, then take a photo of your wires and send them to photos@nest.com.

Smart Heating Features (2)

[table id=245 /]

[expand title=”Read More” tag=”font color= green”]

Room Sensors

Some smart thermostats come with room sensors. These are placed in different rooms around the house and linked to the thermostat and help to monitor the temperature around the house, not just in one room.

Unfortunately, the Nest doesn’t use room sensors but it does have ten temperature sensors within it!

GeoFencing

The Nest has geofencing capabilities. Geofencing is a virtual boundary that is created using a GPS system.

When your phone is linked to your thermostat, your location can be tracked and the thermostat will know when you have left home or when you are coming home and turn the heating on or off.

Energy Saving

You will be emailed a monthly home report, part of which details your energy usage and any savings that you have made.

You will also have access to a large bank of tips and tricks about how to save energy.

Weather Forecast

This device provides you with a local weather forecast, as long as it knows your exact location.

For many users, the Nest thermostat will determine your exact location automatically but if it doesn’t you can easily set it up manually.

Popular Questions

At the time of writing this review (February 2017), well over 1000 questions had been asked about the Nest Thermostat and 942 questions have been answered.

[expand title=”Read More” tag=”font color= green”]

The 5 most popular questions are;

  1. What is the difference between the 2nd generation and the third generation Nest thermostat?

There are three differences between the two devices.

*the third generation works with Amazon Alexa, whereas the 2nd generation doesn’t.

*The third generation has a larger display with a higher resolution and a slimmer body than the 2nd generation device.

*The third generation has 2.4 Ghz and 5 Ghz wi-fi compability whereas the 2nd generation only has 2.4 Ghz compatibility.

2. Can the app be installed on several devices at once?

Yes, it can. It can be installed on several devices (Apple and Android) which are all signed into the same Nest account.

3. If I have a 2 zone heating system, will I need two thermostats?

It is far easier to have a Nest thermostat for each heating zone.

4. Will the Nest make any clicking noises as the heating turns on or off?

There is nothing mechanical in the thermostat to make a “clicking” noise.

It has been designed to work silently.

5. If I am not at home at regular times and my pattern is completely random, will the Nest learn from this?

Not as such! However, if you pair your phone with your Nest thermostat then it can detect when you leave your house and when you are coming home.
