Introduction

The 3rd generation Nest Learning Thermostat is slimmer, sleeker and very elegant.  It features a large, bright display as well as Farsight: you can see the time and temperature you have set from far away.  This device also controls your hot water tank.  Nest Thermostat learns the temperature you prefer and programs itself.  It employs built-in sensors to check that no-one is at home and it knows how long it takes to heat your home to ensure the temperature is perfect when you arrive.  When you leave, it turns itself down to save energy.  You can also check your energy history with the Nest app.

Description

The Nest Learning Thermostat is compatible with most central heating systems including:

  • Combi boilers and heat only boilers, domestic hot water tanks
  • Air-source and ground source heat pumps (heating only)
  • Zoned systems (one Nest Thermostat per zone), heating systems with OpenTherm technology
  • Hydronic underfloor systems

With the Auto-Schedule feature, there is no more programming required.  The Nest device learns from you and just programs itself.  The 3rd Generation device also has Auto-Away which means it will turn itself down after you leave to conserve energy. It has built-in sensors to check that no-one is at home. The device can control the hot water tank, and you can adjust the schedule from your mobile.  It is compatible with Amazon Alexa and Google Home voice control.  There is remote control so that you can alter the temperature, check your energy history and even receive an alert should your home get too cold.

Pros
  • Slim, sleek and compact
  • Easy to use
  • Money saver
  • Fast learning & efficient
Cons

Some customers found the Smart features behaved unpredictably, especially if you don’t adhere to a set schedule which can confuse the learning on the device.  However, Nest has responded:

”It is true that a bit of predictability is required in your schedule. We’re not quite at the level yet of fully knowing what the home owners every move might be but if it helps, we’re probably working on it already!”

Our Opinion

We found this to be a remarkable device it even turns the heating off if it is sunny outside, or turns it on if it is snowing!  It learns your habits and adjusts accordingly.  Once you have tried this heating device you will wonder how you ever managed without it.  We would highly recommend it.

Buyer’s Guide

Smart heating devices are becoming more and more sophisticated due to advancing technology.  Smart thermostats enable you to remotely control your home temperature via Smartphone, tablet or laptop.

A Smart heating device allows for more efficiency and gives you control over your home heating while reducing energy use which in turn cuts down on your electricity bill.  It employs the following three components:

The first plugs directly into your boiler and can wirelessly talk to the second component, the in-home device that is the thermostat and main control.

The third component is an app that is downloaded to your Smartphone, tablet or laptop.  You can then remotely control the thermostat/main control device via the app to adjust your heating from wherever you are.

This is just the basics, but the following seven best Smart heating devices listed above can do far more as you will see.  They can ‘learn’ what temperature you prefer when you arrive home.  They can detect when there is no-one at home with built-in sensors and lower the heat to save energy.  They will send you alerts if the home becomes too cold.  They can control the hot water and much more.

Benefits of a Smart Heating Device

If you lead a busy lifestyle, being able to control your home temperature is a huge benefit.  If you are at a meeting and will be late home, there is no need to heat an empty house – you can just program the heat to come on so that it is warm when you arrive.  If you go away for a few days and forget to turn off the heat, this is easily resolved with your Smart heating device.

You save money as well as energy.  You can check your energy history with the app and make necessary adjustments.  Your home is heated more efficiently which is a definite plus.

Below are the six best Smart heating devices on the market in 2018 in our opinion.

Conclusion

We hope this article will be of use to you in choosing the right Smart Heating device for your home.  While there are many to choose from on the market, we feel the above listed are the most reliable and give the very best value for money.
