Different configurations of inertial radiators
Several types of inertial radiators exist. Their heating core differs and responds to specific needs: Radiators with fluid inertia have a heat transfer liquid which rotates in a closed circuit inside. The fluid, often based on petroleum or glycol, is heated thanks to a resistance. Dry inertia radiators work with resistors that heat ceramic or soapstone blocks, the most efficient. These can also be made of aluminum or cast steel, with their own characteristics of heat setting and cooling speed. Soft heat radiators are a combination of fluid inertia and dry inertia radiators. Oil-filled radiators are similar to radiators with fluid inertia, but can be moved by means of rollers placed underneath.
The importance of heat accumulation
Inertia radiators allow smooth heating. The heating core accumulates heat which is then distributed throughout the room through the body. Then the thermostat controls the heat in order to regulate it to the desired temperature.
Inertia radiator, appreciable heating quality
These radiators heat long and steadily, without sudden variations. The heating is uniform and allows an equal temperature everywhere, including at the feet. The heat transfer liquid or the ceramic or cast iron blocks do not cool immediately, which makes it possible to maintain the heat for some time after the resistors stop. Finally, radiant heating does not dry the air. Take care that the rear of the radiator does not get too hot. This could mean a high heat loss, projected on the exterior walls.
