If in doubt, always choose a higher power emitter so that the thermal emitter works more efficiently. Choosing a power lower than the square meters of the room where you want to install your radiator, would force the device to have to operate at full power to obtain the desired level of heat, without being able to benefit from thermal inertia, and with the consequent energy consumption that this entails.

Please note that you can combine different radiators with different powers in the same room to achieve the recommended power level.

Please remember that these data are indicative, and that to ensure a correct level of comfort, the type of insulation of the house, the orientation of the room and the type of heating…
