With our complete buying guide, you will find everything you need to know about smart thermostats!

What are thermostats?

Thermostats and, particularly, smart thermostats are among the latest trends in house heating. They serve multiple purposes, like switching on and off the heating remotely using the WiFi or creating a heating/cooling schedule according to your needs. But, they are not only plain heaters; they have many more capabilities. They show you information about heating and energy usage and learn your routine by monitoring your daily heating or cooling needs. There are several different thermostats currently available on the market, and each works differently. So, before purchasing one, check our tips to find what is the best buy for you. 

Why do you need a thermostat?

A smart thermostat is always a good investment for any household. There are several reasons why you should buy one, and all of them serve a different purpose.

1. They reduce your energy consumption. 

Using an automatic thermostat to control your heating is the best way to save on bills since it can only adjust the room’s temperature when needed. It might sound insignificant the amount of energy you save every day, but if you add them up, you’ll be surprised. Buying a thermostat feels like more of an investment since it pays off really soon. 

2. They integrate perfectly with your smart home devices.

They also have smart speaker capabilities. The majority of the smart thermostats are compatible with all the well-known platforms -using voice assistants- like Google Assistant, Google Home, Amazon Echo, Amazon’s Alexa, and Apple’s HomeKit and Siri. In that way, you can use voice control commands to adjust the temperature and other automated ways that maximise the efficiency of your system. 

3. They are eco-friendly. 

Installing smart thermostats is an excellent way to save energy for the good of the planet. The amount of energy spent on central heating is massive, and most of the time, experts agree that it’s a waste. Thus, having electronic devices that optimise the systems and monitor energy consumption will affect the planet positively as a whole.

4. They save you time and effort.

Nowadays, in the dawn of automation, most of us want things to be as automated as possible. We might not have time to control everything manually, or we simply want to go back home after a whole day of work and find it cosy and warm. Thermostats have that capability. Who doesn’t want to find a warm place when they go home without doing anything rather than having scheduled ahead of the arrival the heating system?

What to look for when buying a thermostat?

Most modern thermostats provide a wide array of features. If you’re not familiar with them, you might have some difficulty finding what suits you best. Is location tracking really what you want? Or does manual 7-day scheduling fit your lifestyle better? Would you prefer total app control? Or do you want some usage on the thermostat itself? Here’s a list of features that you should be aware of:

1. Zonal heating or entire home heating

There are 2 main types of thermostats. Those who set the temperature to the entire house as a  whole and those who can differentiate the temperature between separate rooms of your home. The former is usually more affordable, they can be installed easier and are better for small houses that don’t have many rooms. The downside is that you may find quite regularly rooms that you’re not using, yet they’re heated. 

Zonal heating, on the other hand, controls each room’s temperature separately via an app. This would be particularly useful if you have many rooms in your house, and you don’t want all of them to be heated. Let’s say, for instance, you’re relaxing in your living room watching TV with your family while no one else is in the rest of the house. With a zonal heating system, you can have your living room cosy and warm and turn down the temperature in other unused rooms. On the downside, the installation process can be tricky and complicated as you might have to install a smart valve on each radiator/ cooling outlet. In that way, it can be more expensive too, as you might have to buy a different thermostat for each area and each radiator of your house you want to isolate.

Before deciding which type you want, weigh the advantages and disadvantages of smart thermostats. Keep in mind that even if zonal heating is more expensive, you’ll save much more on energy bills by controlling which areas need to be heated each time. 

2.  Hot water control

There are smart thermostats on the market that control your heating and, in addition, your hot water. Who wouldn’t like to have some hot water ready when they arrive home after a long day, only by pressing one button on the home app? It’s much more convenient than waiting for your boiler to warm up, that’s for sure. Even if you forget to turn on the hot water from your app, you can schedule the day/time you’re planning to have a hot shower beforehand. So, if you’re off for the weekend, preschedule to have some warm water when you come back home on Sunday evening. 

3. Smart home system integration & connectivity

Every smart thermostat comes with an app and Wi-Fi compatibility, but not all can be integrated with the rest of your home devices, creating that way a synchronised ecosystem. This can range from -as said before- being able to control the temperature with a voice command via a platform, even to control your smoke detectors settings. In that way, the fan will turn off automatically as soon as the fire is detected, preventing the circulation of the smoke in your home. Other options include IFTTT support ( If This Then That) or even tie-ins with home security systems and security cameras

Another important feature that’s really exciting and unique, is the machine learning capabilities of the smart thermostat. This means that your thermostat can learn from your habits and adapt, creating temperature schedules on its own, saving you the trouble of programming a schedule yourself. 

4. Geofencingremote sensors

This interesting feature uses your smartphone’s GPS tracking to establish a perimeter around your house. When you leave this perimeter, the thermostat presumes that you no longer need heating and cooling in your home, and it turns it off. Once you set foot again inside the perimeter, the thermostat automatically turns on the system again. 

Motion sensors provide an alternative to determine if you’re present and, therefore, need climate control.  Some thermostats receive that kind of information from your doors/ windows/ room sensors or even the security cameras.  In general terms, these features are helpful, but sometimes they can get quite irritating, so we recommend testing them first on your own and then decide if you go with that option. Anyway, you can turn the remote sensors and GPS on and off whenever you want. 

5. Compatibility

When choosing a smart thermostat, it’s important to ensure that it’s compatible with your air conditioning, ventilation and heating HVAC system (High-Voltage Heater Support) as well as with your smart devices. Also, in case you’ll be controlling with your thermostat whole-house dehumidifiers or heat pumps, make sure that your device supports them. If you have a particular smart home ecosystem already in place, make sure that it’s not only compatible but offers you full functionality. The last thing you want is to be unable to unlock your smart thermostat’s full potential.

6. App functionality

One of the benefits of a smart thermostat is controlling it remotely via a smart device. Some apps offer more functionality than others. Smart features like geofencing, usage monitoring, rebate/ exemption finder, and other money-saving tools can significantly improve the user experience. Before buying, try to test the app first and see how easy it can navigate and use with your phone’s OS (Android or iOS). Also, check how often the app is updated and maintained.

7. Weather-responsive

Some smart thermostats can analyse the data from the environment, such as temperature and humidity and adjust the temperature of the house -as well as other settings- accordingly. So if suddenly the temperature outside drops and you’re sleeping, your thermostat will automatically read the information and turn the heat up until the house reaches the ideal temperature.

8. Display & Interface

While the main draw of a thermostat is the remote voice and app controllability, the interface on the thermostat itself is also essential. After all, this is what will be on display in your home. Try to think about what information you’d like to see on display. Also, consider the readability of the screen. Is it clear enough to see from anywhere in the room? What’s the resolution? How easy is it to navigate? If it has a touchscreen, how responsive is it?

9. Aesthetics

Regarding their features, most of the thermostats are similar. But design-wise, they have certainly quite a lot of differences. They might be black, white, colourful, round or square in shape. There are ones that stand on a table and others that are wall-mountable. Before investing in one, consider how it will blend with the rest of your rooms’ design and decor.

Can you install a thermostat on your own?

Most of the newer models are usually relatively easy to install and come with helpful and comprehensive instructions so that you can install them without hiring a professional electrician. One vital thing to know before installing is how your system is wired. The wires should be colour coded, and the thermostat should indicate clearly which wire goes where. 

If you live in an old Victorian home, you may see that there is no C-wire in your system. This wire provides constant power to the thermostat. Even though most thermostats have C-wire adapters, it’s recommended to have a new wire installed by a professional to avoid unnecessary damage to the system. In general terms, you can totally install it yourself, but if you feel uncomfortable doing so, you can always go for a professional installation to have peace of mind

Do thermostats save energy and money?

Newer models will use significantly less energy than the old ones or the traditional non-programmable thermostats. It is estimated that if you install a smart thermostat, you will use 8% less energy per year than having a regular thermostat. That percentage is roughly equivalent to £40 in energy savings per year. Of course, it always depends on how you use your heating/cooling system and your personal preferences. If you have it on all the time, without having activated the temperature sensors, your savings won’t be big, but still more than having a conventional thermostat. 

How much should you spend on a thermostat?

If you’re in the market for such a product, in addition to all the above things you should have in mind, you should consider the cost. 

  • Affordable

 In this category, you can find smart thermostats for less than £100. These products will cover the basics. The majority of them are Wi-Fi thermostats, meaning that you should be able to connect them with your mobile phone.

  • Mid-range

Most of the thermostats fall in this category. The price range is between £100 and £200. They have most of the features we discussed above, and they should be sufficient for most houses. They might lack some premium features like voice assistant, but they’ll undoubtedly leave you satisfied.

  • High-end

In this category with a price range of over £200, you will find all the premium models with the most features. They’ll be capable of many different things, like two-stage heating and voice assistance. They support more complex HVAC systems, and, on top of that, they look aesthetically pleasing.

Closure

Whichever smart thermostat you choose, you can be confident that your life is about to get a whole lot easier. Control your heating/ cooling from a distance, from your mobile phone, even if you’re far away from your home and want to find a cosy place upon arrival. Now, thermostats are more modern than ever. They do not simply connect with the internet; they have countless more capabilities that assist you and make everyday life comfortable and hassle-free.
