Which electric heater to choose? (Inertia radiator, radiant, heated floor ...)
Surface to be heated, heat distribution, purchase cost and long-term profitability ... to choose the most suitable electric heating, several criteria must be taken into account.
The most comfortable, the inertia radiator
In the new electric heating solutions, inertia radiators are among the most comfortable.
At fluid inertia, they store heat from an electrical resistance in a so-called “coolant” liquid. With dry inertia, they store thermal energy in solid materials such as ceramic, volcanic stone, cast iron, aluminum, brick or soapstone.
This storage allows a stable and homogeneous distribution of heat, with a good perimeter of radiation: without cold corner, without "jolts" or sudden thermal variations, the heat is gentle, the room will be much more pleasant to live in. In general, inertia technology is recommended in living rooms and living rooms.
The rise in heat of an inertial radiator varies depending on the material. For a quick climb, prefer aluminum. The slowest rise is that of fluid inertia radiators.
If inertia heaters are among the most expensive to buy, they are also the most profitable and more economical in the long run.
The cheapest to buy, the convector and the heaters
The very classic electric convector heats the air directly by resistances. Its cost is rather moderate to purchase… for limited comfort.
The heat is poorly distributed, the air is dry, and it is generally not energy efficient. It remains reserved for small rooms where we do not stay long, such as hallways or kitchens.
For additional use in a bathroom, for example, the fan convector is a good solution.
For the same price range, radiant panel type radiators first heat an aluminum plate to optimize the radiation. The softer heat will be better distributed than with a conventional convector.
For its part, infrared energy allows the convector to have better radiation and more pleasant heat than the conventional convector. Also greedy in energy, it does not heat up over time and is more suitable for bathrooms: we need heat, but we don't stay there!
The invisible, the heated floor
To heat large areas, underfloor heating is one of the essentials.
The resistances placed in the ground, under a chappe, heat the space by the ground in a soft and well distributed heat. The system is completely invisible.
However, this will take time to build up, and remains difficult to regulate in the event of heat input from outside the system, such as by the sun, for example.
