How Does A Thermostat Work?

For generations, thermostats have offered control over a household’s heating system through temperature sensors and adjustment features, and have long been an essential fixture of UK homes. But how do they adjust the conditions in a given room to maintain a setpoint temperature? And what’s the easiest way to control, monitor and change thermostat settings to make your home more energy efficient?


What goes into a thermostat?

Whilst thermostats can come in a variety of forms, with different settings and heating controls, most fall within two categories:

  • Mechanical – These normally control the heating using two metal components, which expand and contract when the temperature changes. An electric circuit then allows the mechanical device to read and maintain room temperature.
  • Digital – These modern thermostats use accurate electric sensors which can detect, react, and adjust to changes in room temperature.


How do you set a room thermostat?

To accurately read the temperature of a room, thermostats should be placed in an area with free air flow, as opposed to a very sunny or sheltered area. When this is done, your thermostat will be easier to manage. Using the interface (whether it’s buttons, dials, a touchscreen etc.), set the temperature to a low but comfortable level; most find this is somewhere between 18-21°C. After that, you’re all set! Simply adjust the temperature through the year as conditions change.


What is a smart thermostat?

If you’re looking to manage your heating in the most energy-efficient way, you’ll need a smart thermostat. These are the most modern thermostat devices and have features that make programming quick and easy, such as Smart Modes and App Control. You can learn more about Wiser Smart Room Thermostats Here.
