There are advantages and disadvantages to different types of heaters. Panel heaters (with and without Wi-Fi) and floor heaters with Wi-Fi have aluminum heating elements that heat up quickly and maintain a low surface temperature. Aluminum heating elements do not burn dust and hair but rather melt them. Therefore, these heaters should not pose a fire hazard. Our floor models without Wi-Fi use heating wires that burn hair and dust. These should not be used without supervision and should only serve as an additional heat source when someone is present. Turn off this heater before going to bed.
Oil-filled radiators take longer to heat up the oil. One advantage of oil-filled heaters is that they do not "burn" the air, which leads to better air quality. This is especially beneficial if there is a lot of dust in the air. When turned off, they also retain heat longer, as the oil takes more time to cool down.
In terms of efficiency, all electric heaters are inherently 100% efficient. This means that all the electricity the heater consumes is converted into heat energy. The control panel and Wi-Fi module use a negligible amount of power.
