What is the difference between the electric baseboards and a radiating panel or inertia-type radiator ?

Electric baseboard heating simply applies and optimises well-known physical and thermodynamic principles, which are convection, inertia, radiation, the fact that heat rises, that the cold enters a room mainly via external walls.
A radiator is a point of diffusion of heat in the middle of a wall. Electric baseboard heating distributes this diffusion over the entire width of the wall, at ground level. It thus creates an ascending thermal wall along the wall which prevents the penetration of the cold.

The wall accumulates (inertia) the temperature which reaches 26° at approximately a height of 1.5 m and restores heat by radiation.
This a low or high temperature heating system which provides the following advantages:
• Maintaining an ambient humidity rate between 50 and 60%
• A slow convection which provides enough time for the ascending air to cool, prevents hot air pockets at ceiling level and maintains dust at ground level.
• Near the baseboard or at the opposite end, at 1 cm from the ground or 1 cm from the ceiling, the temperature difference is below 1 degree.
• Significant reduction of the installed capacity.
