Abstract: A panel heater with enhanced safety features for us as room heaters disposable on at least one of a wall and a floor includes: a flat panel heater component; at least one protrusion provided on at least one of a top surface and a bottom surface of the flat panel heater component; and a covering surrounding at least one of the top surface and the bottom surface of the flat panel heater component. The flat panel heater component includes one of a) an electrical heating element incorporated in an oil filled chamber; and b) a wire heating element covered with an electrical insulating material. The at least one protrusion creates an air gap between at least one of the top surface and the bottom surface of the flat panel heater component and the covering, thereby reducing temperatures attained on surfaces of the flat panel heater component and the covering significantly.
