Is there any significant difference between Manual and Digital h

The key difference between manual and digital convection heaters is the latter’s ability to adjust room temperature automatically and with much more precision. Manual heaters offer five temperature settings, while digital heaters allow the user to select a specific temperature. The most important aspect of this is energy consumption. Digital heaters are able to monitor ambient temperature and reduce power consumption as it nears the set temperature, offering higher energy efficiency compared to manual devices. Digital heaters are also able to switch off and on automatically depending on changes to the room temperature, while manual heaters are only equipped with a thermostat to control device operation, with no continuous temperature monitoring to allow precise adjustments. As a result, they offer lower energy efficiency compared to digital models.
