How energy efficient electric heaters are depends primarily on the type of technology being used and the application layout. The most efficient electric heater will use technologies such as directional infrared heating meaning that the energy consumption is maximized to ensure heat both reaches and is absorbed by users. Additionally, proper layouts entail thoughtful placement for necessary heat coverage only where it’s needed so as not to waste additional energy on unused spaces.
