Q: Is it worth getting a smart thermostat?

While everyone has different requirements for a smart thermostat best suited to their smart home, the range of choices available means there’s a smart thermostat out there just for you.
Q: What is the point of a smart thermostat?
The best smart thermostats even offer zoning, which means you can fine-tune your heating on a room-to-room basis.
Q: How does a smart thermostat work?
Smart thermostats work by connecting your heating system to the internet through your Wi-Fi connection so that you can control your heating remotely on your device of choice.
Some smart thermostats offer a range of other options, for instance, sending you notifications to warn you of temperature alerts and can even learn your routines through AI to adjust the temperature automatically.
Q: How do I control my smart thermostat?
Smart thermostats can be controlled either from the thermostat’s device or from your device, such as a mobile phone.
When choosing the best smart thermostat, you need to ensure that it is compatible with your existing smart home setup.
For instance, if you’re using Apple’s HomeKit, make sure the smart thermostat can connect to this service.
Q: What are the advantages of a smart thermostat?
Smart thermostats offer a range of advantages over a traditional central heating setup.
The basic smart thermostats will allow users to control the heat of their home as one central block, as well as setting timers and schedules.
For example, different routines can be programmed for weekdays and weekends to match the times you get out of bed.
The best smart thermostats bring in a whole host of additional features.
These include zoning so that you can control individual rooms and geofencing, which knows when you’re on the way home and can put the heating on ready for you.
Additional smart home integration lets you sync them with other devices such as motion sensors for even greater versatility.
Q: What are the disadvantages of a smart thermostat?
While smart thermostats offer a great range of controls, they aren’t for everyone.
First, you’ll need to check if your current heating is compatible with the devices, and the cost of installation is also something you’ll need to consider.
While some smart thermostats can be set up in minutes, others will require a professional to come round and install them.
Programming the more advanced smart thermostats can also be time-consuming, and if you haven’t got the patience for this, it’s another disadvantage to consider.
If you live alone and work from home, chances are you’re not going to require the kind of nuanced control the best smart thermostats provide, either.
Q: Does a smart thermostat make a difference?
The additional scope a smart thermostat brings to controlling the temperature of your home absolutely makes a difference.
Some of the more advanced features, such as detecting when a window is open or turning up the heat to prevent your pipes from freezing over in the winter, can save a lot of hassle and money.
And as with any other smart device, the more you put into getting your head around its features, the more difference it will make in your life.
Q: What is the difference between a smart thermostat and a programmable thermostat?
When using a standard programmable thermostat, you can set a pre-programmed daily and weekly schedule to adjust the temperature in your home.
Programmable thermostats can be tricky to use properly, and smart thermostats solve the issues these devices have.
Q: Do you need Wi-Fi for a smart thermostat?
The (very) short answer is yes.
While you’ll still be able to use the main thermostat control to adjust the temperature, unlock all the additional features, and access your heating via your phone, you’ll need a Wi-Fi connection.
If you don’t have a Wi-Fi connection in your home (which is unlikely), you’ll have to make do with a more traditional programmable thermostat.
Q: How long do smart thermostats last?
Smart thermostats are durable bits of kit, and the average device can be expected to last you somewhere in the region of 10 years.
It’s worth checking the warranty on your smart thermostat to make sure you’re aware of when you’ll need to consider servicing your equipment.
If you think there’s a problem with an old smart thermostat set up, you should look into troubleshooting the device for any issues.
If the temperature settings suddenly don’t feel right, or radiators aren’t turning on when they should, conduct the necessary checks to see if you can isolate the problem and get it fixed.
Q: Can a smart thermostat detect room occupancy?
If you want to set up your smart thermostat to detect room occupancy, you’ll need to pair the device with motion sensors.
These will notice whenever someone is in the room so you can program your smart thermostat to behave accordingly.
You’ll need to check to make sure your smart thermostat is compatible with the relevant smart home device ecosystem, too.
Q: Are smart thermostats hard to install?
Smart thermostats are relatively easy to install, provided you follow the installation guidelines carefully to avoid making any mistakes.
For most smart thermostats, you’ll need to switch off the entire HVAC system at the breaker panel, and there will be some wiring required to set up your new thermostat on the wall.
In some cases, professional installers will visit your home and get everything set up for you, but this depends on which smart thermostat you choose to install.
Q: Are smart thermostats really worth it?
Smart thermostats earn their worth on two key metrics: convenience and cost-saving.
If you’re looking for a flexible home heating system that learns your habits and can be easily programmed, the benefits absolutely make these a worthwhile purchase.
While the energy-saving implications of using a smart home are a little murky, there’s no doubt a greater degree of climate control means that your energy bills are likely to go down.
With a wide range of smart thermostats available to choose from, making sure you invest in the one which matches your needs and fits your budget can be headache-inducing.
This guide should set you well on the way to making the best decision for your new smart thermostat, whether it’s your first time buying one or if you’re upgrading to a better model.
