Ideal for improving thermal comfort, the inertia radiator provides constant heat without consuming a lot of energy.
Its design allows it to store the heat produced in a coating allowing its accumulation to distribute it gradually.
This mode of operation makes it possible to maintain the temperature while achieving substantial savings in use.
It advantageously replaces a very energy-intensive classic model or a radiant-type radiator that tends to dry out the air and only heat the area in front of it.

Why buy an inertia radiator in 2022?
Currently, the electric inertia heater is the most efficient heating model using electricity.
Equipped with a resistance and a heating body accumulating the heat produced by the first, it is regulated by a thermostat.
The latter is responsible for triggering the resistance to maintain the temperature according to the user's instructions.
It provides a homogeneous return of heat in the room unlike a radiant radiator.
In addition, it is a heating almost without any maintenance apart from a simple dusting.
Its installation is also simplified.
It can take the place of an old radiator as long as the electrical supply is correctly sized to supply it.
How to choose your inertia radiator according to your accommodation?
Inertia radiators use different materials such as lava stone, refractory brick, cast iron, ceramic or soapstone.
Each of these materials has advantages and disadvantages.
Some heat up faster like ceramic, but do not accumulate heat as well as soapstone for example.
Cast iron has many advantages, but is particularly heavy, it must be firmly fixed to a wall capable of supporting its weight.
You can also opt for a fluid inertia radiator, but its performance is less interesting, the heat transfer liquid it contains does not retain heat as well as a dry inertia radiator such as ceramic or lava stone.
The dry inertia radiator is an ideal choice to replace an old radiator. Its performance is high while significantly reducing power consumption. It is able to provide a very appreciable soft heat.
