How Does A Thermostat Work?

Thermostats work by detecting temperature changes in a room using one of a few methods. Usually, this is done through metallic components or electric sensors, indicators that a thermostat will use to change the room temperature accordingly. Your home’s central heating system then does the rest to maximise comfort and control. 


What goes into making a thermostat work?

For generations, thermostats have offered control over a household’s heating system through temperature sensors and adjustment features. They 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?


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 room temperature, thermostats should be placed somewhere with free airflow, 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. For most people, this is somewhere between 18-21°C. After that, you’re all set! Simply adjust the temperature throughout 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 devices operate through your central boiler, which is the primary control centre for a smart room thermostat. You can then create heating schedules and change Room-to-Room Temperatures using an app downloaded onto an Apple or Android smart device. This lets you control your home’s smart heating system anytime, anywhere.


Moreover, they’re the most modern thermostat devices and have features to make programming quick and easy, such as Smart Modes and App Control. You can learn more about Wiser Smart Room Thermostats Here.
