The inertia radiator is a heating solution that combines the comfort of gas central heating with the simplicity of electric radiators. These radiators have the particularity of accumulating and then diffusing the heat, which brings a comfort and a soft heat.
How does an inertia radiator work?
This type of radiator works in two stages. First, a resistor warms a mass that can be either solid or liquid. The heat accumulates and then diffuses steadily. This feature features the inertia radiator among the soft heat heaters.
The heat is distributed by radiation, like the rays of the sun. The solid bodies of the room are heated first and then warm the ambient air homogeneously.
There are several types of radiator with inertia:
- The radiator with dry inertia: the refractory mass which composes it is solid (bricks, stones, cast iron, aluminum, etc.).
- The radiator with fluid inertia: the mass which equips it is a fluid in a closed circuit (oil, glycol, mineral or vegetable oils, etc.). An example is the heat transfer fluid radiator or the oil bath radiator.
The radiator with inertia: advantages and disadvantages
Thanks to the constant diffusion of heat, the radiator works even off, which allows a significant saving of electricity. Economy which can be increased if one associates a programmer with the apparatus. The temperature rises rapidly and the heat is homogeneous.
Side disadvantages, the radiator is a device whose prices are higher than other electric heaters, even if it is quickly profitable. Similarly, it diffuses heat from both sides: when placed against a wall, it is necessary to provide a reflective insulation. Finally, it is not suitable for a room where it is desired a rapid increase in temperature over a short period, unlike fan heaters.
