Thermostats, Controls and Sensors: What’s the Difference?

When it comes to modern heating systems—whether it’s underfloor heating, air source heat pumps, or radiators—you’ll often hear terms like thermostats, controls, and sensors. They might sound similar, but each plays a unique role in how your heating system works. At BPC Heat, we know that understanding the difference can help you make better decisions for comfort, efficiency, and cost savings.

What Is a Thermostat?

A thermostat is the device most homeowners are familiar with. It’s the part you use to set and adjust the temperature in your home.

- It measures the room’s current temperature.

- It switches the heating system on or off to maintain your chosen setting.

- Modern thermostats can be programmable or even smart, allowing you to control heating schedules or adjust settings from your phone.

👉 Think of the thermostat as the “user interface” between you and your heating system.

What Are Heating Controls?

Controls refer to the wider system that manages how your heating operates. This includes:

- Timers and programmers (to decide when the heating should run)

- Zoning systems (where different areas of the house can be heated to different temperatures)

- Smart home integrations (like apps, voice assistants, or automation features)

Good heating controls allow you to customise your heating so you’re not wasting energy heating empty rooms or running the system unnecessarily.

👉 Controls are the “brains” of the system, optimising when and where heat is delivered.

What Are Sensors?

Sensors are the hidden heroes of heating systems. While thermostats are the visible part you interact with, sensors are often tucked away in walls, floors, or even outside. They gather data to make sure the system runs efficiently. For example:

- Room sensors measure the air temperature.

- Floor sensors are often used with underfloor heating to prevent overheating.

- Outdoor sensors can detect the weather, helping systems like air source heat pumps adjust performance accordingly.

👉 Sensors are the “eyes and ears” of your heating system, feeding information back to the controls and thermostat.

How They Work Together

- Sensors provide the data (temperature, conditions).

- Controls use that data to decide when and how to heat.

- Thermostats let you set your preferences and make manual adjustments.

When combined properly, they create a heating system that is comfortable, energy-efficient, and easy to use.

Why It Matters

Choosing the right thermostats, controls, and sensors for your system can make a big difference in:

- Energy savings – by avoiding unnecessary heating.

- Comfort – by keeping temperatures consistent where you need them.

- System longevity – by preventing overuse or strain on your heating system.
