1) We do not recommend the use of convectors.
2) For the range of inertia radiators, soft heat radiators or certain radiant panels, we recommend electric heaters with an energy label A (presence/absence detection, open window detection, consumption indication).
Beware of the aptitude coefficient, which reflects the performance of the radiator and should be as low as possible. For more information on this subject.
3) For the family of high-performance radiant heaters, we recommend the sub-family of far-infrared heaters. In this family we recommend heaters with a certified radiation rate of > 50%. As there is no standard for this element, we recommend requesting a study that justifies the radiation rate claimed by the distributor. These radiators cannot provide an aptitude coefficient as they do not «embed» a thermostat in the heater (which has many advantages). As the main manufacturers are German and Austrian, CE and TUV certification is the norm.
