Top 7 Smart Thermostat Suppliers 2020

Smart Thermostat

What’s in this guide?


Smart thermostats are the newest addition to the range of smart gadgets for your home, following smart meters and AI like Alexa.

They control your heating using the internet, meaning that you can switch your heating off remotely via your phone or smart tablet.

This can be handy if you’re going away at the weekend and want to ensure that your home isn’t using an excessive amount of energy.

Or, if you’re at work and you can’t shake the feeling that you left the heating on.

This guide will tell you everything you need to know about smart thermostats, including where you can get them, how they compare against each other and the types of costs you can expect.

What is a Smart Thermostat?

Not to be confused with smart meters, which sends your energy usage information automatically to your supplier, a smart thermostat takes care of the heating in your home.


Like a traditional thermostat, your smart thermostat controls the heating in your home, but with a few key differences.

For one, you can control everything remotely from your phone – even if you just can’t be bothered to get out of bed in the morning to turn the heating down.

Secondly, some smart thermostats can even learn your routine which would then lead to it being able to predict when you want your heating turned on and off. It should then do that for you automatically!

Finally, smart thermostats tend to come with an added load of extra features that can help you better understand your heating and your energy usage. This can include things such as a breakdown of how much energy you use as well as even doing things such as controlling your hot water, provided you don’t have a combi boiler.

How can they save me money?

Smart thermostat Reviews


Mark Davis on Amazon: Don’t buy this. If you want a headache with the so-called Geo Location function, then go ahead. In the process of ripping mine out.


Andrew C Rowsell-Jones on Amazon: The remote app for smartphones is super basic. It should mimic the controls offered by the device itself. It does not. You can see Honeywell is a heating and controls business, not a software developer. If your customers value fancy mobile apps install a Nest, not a Honeywell.


Berther on Amazon: It does what I want, easy to use, much cheaper than competitors. My house schedule changes week by week, so this is a perfect solution for me. I spend a few minutes adjusting heating times on a Sunday and that it for the week.


Rick on Amazon: Installed and working and this oozes quality, the stat was very easy to program to Wi-Fi and set up and even has a program schedule to work with the auto-learning. Stat body has some weight which backs up the quality of feel and touch.


Vincent Cullen on Amazon: The thermostat is simple to use and when weather conditions change it is easy to alter the Target temperature to maintain a stable, balanced temperature particularly during icy conditions. A system is expandable and can include motion detectors and lights. Great piece of kit and easy on the eye.


Steven Williamson on Amazon: The app to control central heating and hot water are so simple to use I have also installed on wife’s phone for her to use even though she usually’s not good with technology. The system does everything I need, looks very good and doesn’t have and daft panel flaps that eventually break.


CR8 on Amazon: Tado is hands-down the best smart thermostat on the market, and so far, the best smart home device I own. The best thing about it is that you don’t have to think about it once it’s installed; as soon as you leave your house, it starts saving you money.
