Smart Thermostat Buying Guide & FAQ
A lot of thought and care goes into the selection of products on our buying guides. Every single product has been through an extensive sorting process, matching up to our guidelines, feature expectations, practicality, and more. We understand that you’re likely to have a few niggling questions sitting in the back of your mind, especially if you’re about to hit purchase on the thermostat of your dreams. This is why, with you in mind, we’ve got all the handy information available for you below.
How We Chose Our Selection Of Smart Thermostats
As we mentioned, the products in our buying guides are selected very carefully. The products in this guide are the best of the best, meaning they have met (or gone above and beyond) our guidelines. The following three aspects were the most important when finding the best thermostats, and you can rest assured we checked everything countless times so that you’re only presented with the most perfect product. From the quality of brand to customer reviews to affordability, we’ve thought of it all.
Brands - It might feel like the easier option to purchase a thermostat from a designer brand, but this doesn’t always mean that you’ll end up with the best product. Of course, well-known brands are popular for a reason, and the excellence in their products will be sure to keep you satisfied. However, when it comes to our buying guides, we understand that top-of-the-range brands aren’t accessible to everyone, as they usually come with a hefty price tag. This is why we’ve carried out thorough research into smaller brands too; the brands who are working away in the shadows yet still creating awesome products. While researching, we treated each brand the same, no matter how big or small they may have been. This not only gave every thermostat out there a fair chance, but it meant that there is no bias data in this buying guide whatsoever.
Reviews - What better way to judge the success of a product than with customer reviews? It’s all well and good reading a list of awesome features that a product has, but when out in the real world, does the product live up to its expectations? We had hours of entertainment sifting through reviews, and these played a huge role in deciding which final nine thermostats made it onto our buying guide. All products mentioned were commended by buyers all over the globe, so expect to see plenty of 4 and 5 star rated products. You deserve only the best.
Price - Smart thermostats have plenty of impressive technology stacked up inside them, meaning that the price tag can sometimes reflect. What you might not know, however, is that cheaper products which perform just as well are available for you to get your hands on. We kept budgets in mind when choosing the products in this guide, and we feel confident enough to say that there is a thermostat to fit any budget in this guide. So, whether you’ve been saving for this gadget for some time or just want a quick fix which does the trick; we’ve got you covered. Just bear in mind that if you’re on the hunt for a thermostat with very specific features, that the price tag may go up. If you want one with Wi-Fi and geofencing, for example, you can be expected to pay slightly more than the thermostats which do not have these awesome features. Of course, the money you spend will all be worth it though, and the products in this guide are accurately represented with their prices.
Features To Look For In Smart Thermostats
The very best smart thermostats will have a variety of different features which you’ll soon realise you can’t live without. You might not even recognise the name of some of these features, but as we start to explain what each one is, you’ll realise how epic they are. Use the following list of features as a pick-n-mix guide to establish which one’s appeal to you the most. From here, you’ll be able to make an informed decision on what features you’d like your thermostat to have. Are you ready?
C-Wire - Thermostats use up a lot of power, meaning they’re going to need as much energy as they can get. Not all thermostats will require a C-wire, but it’s perfectly common for many designs to need one. Basically, a C-wire (also known as a common wire), helps to provide a continuous flow of power to the thermostat. Most of the time, Wi-Fi thermostats will need a C-wire so that all of the advanced features have enough energy to run to their best ability. If you have no problem with a wired thermostat, then a C-wire won’t be a problem, but just be aware that not all homes are equipped with one. Check if you can cater for a C-wire before making a purchase - there will be plenty of wireless options available if your home won’t allow one.
Self-Installation - Are you okay with being a handyman or would you rather someone did the job for you? If you’re purchasing a thermostat online, then there’s a high chance that you’ll be expected to install the device yourself. Don’t worry though - this whole process is usually fairly simple and you’ll be given a clear guide to follow. The makers of all of these wonderful thermostats don’t expect their buyers to be qualified electricians, so you won’t find the task too much of a struggle.
If you feel that self-installation isn’t the right route for you, then get in touch with your local technician; they’ll be more than happy to get the job done for you. Some thermostats even have a team of installers ready to help you; take Nest as an example, who have their very own Nest Pro Installers to give you a helping hand.
Zones - Some thermostats are so smart that they even use the power of teamwork to keep your home a reasonable temperature at all times. A zoned system involves having multiple thermostats working together to control a single heating system. This means that different areas of the house will receive different treatments depending on what the temperature is in that particular zone. The zoning feature is particularly important to have if you live in a large residence or a residence which can never hold a consistent temperature throughout.
Sensors - If you want a thermostat which won’t let you down with questionable temperature control, then a sensor feature is what you’ll need. Sensors are placed around the home and will act as a wireless alert system for your thermostat. When that particular area of the room gets too cold or too hot, the thermostat will be alerted to make some tweaks. Sensors are a particularly modern feature and eliminate the problem that old designs had when they wouldn’t distribute heat effectively.
Motion Activation - Similar to the sensors, motion activation means that the thermostat will get to work when it senses that you, or someone else, is in the room. This is a pretty nifty feature to have for those wishing to lower energy usage, as it will only turn on when you’re using it.
Another form of motion activation consists in the screen of the thermostat. As you begin to approach the thermostat, the screen will light up and give you an array of options to work with. Once again, this is a great tactic to avoid wasting energy and means that tweaking temperatures in a dark-lit room won’t be a challenge.
Smart Home Integration - Thermostats which are equipped with smart home integration really are products from the future. Just like the globally-known Amazon Alexa, a thermostat with smart home integration will mean that you can control all other devices in your home at the same time, usually with the help from a single app. Need to turn the heating on? No problem. How about some music? Sure.
Smart Voice Assist - Gone are the days of having to walk up to a device to turn it on. Now, in our incredibly lazy and technology-riddled world, we simply have to say a command to get the desired action. The story is no different with thermostats either, as nowadays, a lot of smart thermostats will have smart voice assist, allowing you to make changes to the temperature of a room without having to move a muscle. Whether you’re cosy in bed or hooked on an epic film, smart voice assist will be your new best friend, in a completely not-so-sad way… we promise.
Geofencing - If setting schedules aren’t something you’re great at or your routine differs on a daily basis, then getting a thermostat with geofencing enabled with help you to use energy efficiently no matter where you are. If you’re unsure as to what a geofence location is, it’s basically the particular area that your home falls in. When you enter the geofence area, your thermostat will be notified and will start to change the temperature accordingly. Likewise, when you leave the geofence area, your thermostat will understand that no one is home and cut back on the energy being used. Who knew that a smart thermostat could take such great care towards your wellbeing?
Smart Thermostat FAQ
Q: Can you install smart thermostats by yourself?
A: The majority of smart thermostats require self-installation, meaning you’ll be expected to follow a guide and set up the device yourself. This saves time and money outsourcing an electrician to do the job for you and thanks to the handy instructions, self-installation will be accessible for everyone.
Q: Do smart thermostats save you money?
A: If your smart thermostat has a scheduling feature or geolocation enabled, then it will be sure to save you money in the long run. In fact, many thermostats claim that you’ll get your money back within just two years of use! By using a thermostat, you are in full control of how and when energy is used around the house, meaning when it’s not needed, it won’t be circulating. This means that you aren’t throwing money down the drain when you leave the house, as your thermostat will know when to turn everything off.
Q: Does lowering the thermostat save money?
A: Yes - lowering the temperature on your thermostat will help you to save money. When you bring the temperature down to a lower setting, it will be using less energy to heat your home, meaning you will be cutting down on electricity use and therefore saving costs. You might find that the savings from doing this aren’t anything too drastic, but every little bit helps, so it’s worth lowering your thermostat whenever possible. Even if it’s just by a few degrees, your electricity bill will show the difference.
Q: Is it better to turn the heat off or down?
A: Although it might seem like the logical option to turn the heating off when you leave the house, it’s actually more practical just to turn the temperature down. Unless you’re going on vacation over a long period, turning the heating off will actually end up using more energy as it will have to reboot whenever you get back in the house. The thermostat will be working hard to get back up to a more comfortable temperature, and as a result, will be wasting both time and money. So, for a more comfortable experience and to avoid the shock of entering a freezing home, turn the heating down rather than off.
Q: What should you set your thermostat at in the winter?
A: The winter months are going to be when your heating is at work the most, so it’s important to figure out the setting which will keep you toasty but not result in an eye-watering bill each month. Finding the best temperature will depend on your preferences, but as a general rule of thumb, it’s recommended to set the thermostat to anything between 68-72°F when someone is at home, and 62 to 66°F when the house is empty. These temperatures should give you a comfortable way of life without having to worry about frostbite or overheating.
