What is a Smart Thermostat?
Before we list the best smart thermostats available in the UK, let’s find out exactly how a smart thermostat works and what makes them different to a conventional thermostats.
Smart thermostats can be controlled from mobiles and tablets, giving you the power to adjust the heating around your house whether you’re at home or out and about. All you need is an internet connection.
Not only are more homeowners turning to smart thermostats but other smart devices too, such as voice-controlled devices like the Google Home and Amazon Alexa. Many smart thermostats can be paired with these devices, allowing you to control the heating with your voice. It’s important to check that the smart thermostat you’re considering is compatible with your voice-controlled device before purchasing though.
One acronym you might see quite a lot when looking at buying a smart thermostat is IFTTT, which means “if this, then that”. Smart thermostats that have IFTTT capability can be set to activate when a room drops to a temperature you’ve selected.
Is a Smart Thermostat Right for Your Home?
Smart thermostats can help with reducing energy bills and this is a common reason why many homeowners are interested in installing one. You’ll feel the most benefit, compared to a conventional programmable thermostat, if you’re in and out of your home at different times of the day and don’t have a set routine. This is because many smart thermostats will be able to ‘learn’ your habits and adapt to the way you use central heating and geolocation technology gives smart thermostats the ability to know when the house is empty.
Despite these energy saving technologies, a smart thermostat will work best when paired with a modern, highly-efficient boiler and if you want to get quotes for a new boiler or book an appointment with a fully-qualified heating engineer about thermostat options, send us an enquiry today.
Something that puts some homeowners off installing a smart meter is thinking that they wouldn’t then be able to switch energy suppliers. The good news is that you can continue looking for a cheaper energy bill and still switch to another supplier after you have a smart thermostat installed.
How do Smart Thermostats Help You Save Money?
For many, saving money on energy bills is the primary reason for installing a smart thermostat and they boast many features to help your home do just that.
- Learning: A smart thermostat will track how you currently heat your home and programme itself to this schedule so you only use energy when you need it.
- Geolocation: Using your smartphone’s GPS location a smart thermostat can tell when you are home or away and turn the heating on and off accordingly.
- Motion Detecting: A monitor is used to detect when you leave and enter your home so that heating can be automatically adjusted.
- Weather Responsive: A smart thermostat checks the weather forecast or temperature outside and adjusts your home heating to account for this. This stops energy wastage on warmer days and prevents frozen pipes in winter.
- Website and Smartphone Controls (Control the central heating from a mobile phone): Control heating from your mobile phone or via website controls wherever you are, which means you can turn the heating up or down wherever you are.
- Multi-zone: You can control individual rooms or ‘zones’ in your home separately, so you only heat the areas you are using.
How to Choose the Right Thermostat for your Home
As well as the many features you can look for in a smart thermostat, there are a few essentials you might want to consider before committing to a certain make and model:
- Compatibility with other smart technology (Google Home, Amazon Echo)
- Hot water control in addition to central heating
- Whether compatible smart thermostatic radiator valves (TRVs) are available
- A mobile app for complete control
Before jumping in and buying a smart thermostat, it’s a good idea to speak with your energy supplier to see if they recommend a certain model or supply their own. Doing this could also help you to get a great deal.
