The U.S. Consumer Product Safety Commission does not list any recalls for Delonghi portable heaters or any other Delonghi products. The site features incident reports, but these reports are filed by individual consumers or agencies other than the CPSC. They do not constitute an advisory or recall.
Delonghi's portable heater FAQ provides consumer safety recommendations. These safety tips include keeping heaters away from children and pets, clearing the area around the heater of foreign objects, not using heaters with frayed or damaged cords and ensuring the heater does not get wet. Delonghi recommends against dissembling or servicing their portable heaters for safety reasons.
