Ceramic heaters can take a while to heat up the air around you, but they’re slightly more efficient. They also tend to louder because of the fan, but are better suited to larger spaces than infrared heaters. Infrared heaters are quieter and more effective in heating the radius they’re in. However, the area they can heat is relatively small, they tend to be pricier and there’s some unsubstantiated concern that frequent use may be linked to skin cancer.
