Which is the Best Smart Thermostat?

With rising energy costs a top concern for British homeowners right now, smart thermostats let you take control of your energy usage. These clever devices allow you to tailor your heating to suit your lifestyle – reducing wastage and saving you money on bills.

How do Smart Thermostats Help You Save Money?

  • 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: You can control a smart thermostat on the go through your phone or a website. This means no more forgetting to turn the heating off on the way out.
  • Multi-zone: You can control individual rooms or ‘zones’ in your home separately, so you only heat the areas you are using.
