Heating is one of the highest expenditure items in the budget of French households, representing more than 1,500 euros per year.

A cost that has led to the development of connected objects in the home, and in particular thermostats.

These devices, which are numerous on the market, offer energy savings by managing the temperature of the home according to various criteria.

But are they really relevant?

How it works ?

Connected thermostats are connected to your heating installation and work with the house's Wifi.

Unlike the classic thermostat, which can only adjust the temperature, the connected model offers many possibilities.

This smart device first optimizes the temperature of your interior according to its surface and its insulation via the dedicated application.

It also makes sure to maintain the desired heat throughout the day or night.

They also allow you to learn about your energy consumption through graphs and statistics.

The most sophisticated models even adapt to the lifestyle of the occupants.

Indeed, some are able to anticipate the needs of users by starting the heating before their arrival through geolocation.

They can also be programmed remotely using the app.

Others consult weather data to heat your home to the right temperature based on weather conditions.

Finally, the most sophisticated devices can detect open windows and suspend the heating or alert the user in order to avoid any waste.

What advantages?

The first use of a connected thermostat is obviously to save you money.

According to the Ecological Transition Agency (formerly Ademe), this type of device would reduce, on average, the amount of the heating bill by at least 10%.

But it can go up to 20 or 30%.

If these smart tools cost between 120 and 250 euros to purchase, their investment can therefore be amortized in just one year.

Finally, connected thermostats make life easier by anticipating your needs and managing the heating in the house for you.

However, they also have some drawbacks.

First, most connected thermostats are not able to manage the ideal temperature in several rooms at the same time.

You have to invest in different boxes if you have several floors, for example, which can quickly become complicated in terms of management.

Second, not all heaters are compatible with connected thermostats.

Indeed, electrical installations (adopted by nearly 40% of French people) cannot work with this type of system.

It is only viable with boilers controlled by a pilot wire.

So do your research before taking the plunge.
