How to optimize your heating with a smart thermostat for sustainable savings?

In a context where energy expenses represent a significant part of our household budget, optimizing heating becomes a priority. In 2025, with the constant increases in energy prices such as gas and electricity, it is crucial to explore technological solutions that allow for energy savings. Among these solutions, connected thermostats stand out for their ability to provide comfort and efficiency. This article guides you through the world of connected thermostats, allowing you to optimize your heating and achieve sustainable savings.

The advantages of connected thermostats in heating optimization

Connected thermostats have revolutionized the way we manage our thermal comfort. Their connection to the Internet allows them to be controlled remotely, via a smartphone app, but also to learn and adapt to user habits. Here are some of their advantages:

• Personalized programming: Have complete control over your home's heating based on your schedule.

• Energy savings: A reduction in heating costs of up to 15%, according to a recent study.

• Increased comfort: Enjoy temperature adjustments to the exact degree based on your preferences.

• Interaction with other devices: Easy integration with other smart home equipment such as Philips Hue lights or security systems.

How do connected thermostats work?

To better understand how to take advantage of these devices, it is essential to know how they work. A connected thermostat uses sensors to monitor the ambient temperature of your home. Depending on your settings, it regulates heating to maintain the desired temperature.

A significant aspect is their learning capability. For example, after a period of use, a thermostat like the Google Nest can anticipate your heating needs, adapting even to outside weather conditions, which optimizes energy consumption.

The best connected thermostats in 2025

In 2025, several models of connected thermostats stand out in the market. Here is a selection of the best that combine performance, price, and features.

This selection allows you to make an informed choice based on your specific needs. Each of these thermostats features interesting functionalities, but it is vital to consider which device best integrates with your existing heating system.

Choosing the thermostat suitable for your heating system

Before making your choice, it is essential to check the compatibility of your thermostat with your boiler or heating system. Here are the key points to consider:

• Type of heating: Each thermostat may not be compatible with all types of boilers (gas, oil, electric, etc.).

• Installation complexity: Some models require the intervention of a professional for proper installation.

• Advanced features: Some options such as geolocation or compatibility with third-party devices (like Qarnot for decentralized heating) can influence your choice.

How to configure your thermostat to maximize savings?

Once you have chosen your connected thermostat, it is essential to configure it correctly to achieve real energy savings. Here are some practical tips:

Setting the comfort temperature

Defining a comfort temperature is the first step. Generally, recommendations include:

• 19°C for living areas such as the living room and kitchen.

• 22°C only during active use in bathrooms.

• 17°C in bedrooms for good sleep.

By having defined time slots, do not hesitate to lower the temperature during periods when you are absent or at night. This allows you to generate significant savings.

Program heating modes for each room

A modern thermostat allows differentiated control of heating in each room. Thus, tailored programming for each room provides optimal comfort without overconsumption. For example, if you do not use the guest bedroom, there is no need to heat it, while a living space should be kept at a pleasant temperature.

Manage the maintenance and efficiency of your thermostat

Maintaining your thermostat and the heating system in general is essential to ensure their efficiency over the long term. Here are some simple steps to follow:

• Regular checks: Regularly check your thermostat to ensure all functions are working correctly.

• Boiler maintenance: Proper maintenance of your boiler is necessary to ensure its proper functioning and longevity.

• Connection tests: Check your thermostat's connection to the Internet to avoid any remote control issues.

How to detect overconsumption?

Use the features of your thermostat to monitor your energy consumption. For example, the Tado° offers detailed reports on your usage. Thus, you will be able to adjust your programs and spot anomalies. Quick adjustments can make a significant difference on your final bill.
