A device for thawing a frozen drink in a glass drinking bottle, with: - a housing; - a bottle receiving space, which is arranged in the housing and which is configured to receive a glass drinking bottle with a frozen drink for thawing; - a heating means, which is arranged in the housing and has radiant heaters, which are arranged around the bottle receiving space in order to radiate heat energy onto the glass drinking bottle during the thawing operation; - an electronic circuit, which is configured to detect whether at least one of the radiant heaters is defective, - a thermal insulating and cooling means, which is arranged in the housing, the thermal insulating and cooling means having: - a thermally insulating space, which is formed in the housing between the radiant heaters and an outer housing wall and so as to circumferentially encompass the outer housing wall; and - an air cooling, in the case of which cooling air is drawn from the surrounding area into the housing by means of an air conveying means via an air inlet and is conducted in the housing via an air duct to an air outlet, wherein the air duct is formed so as to encompass at least the thermally insulating space; characterized in that a regulating algorithm is configured to determine the heating power missing due to defective radiant heaters and to compensate it with the help of a longer heating time in such a way that the heat energy supplied as a whole by means of the non-defective radiant heaters remains constant, independently of the number of the defective radiant heaters, insofar as a defined number of defective radiant heaters is not exceeded. - a housing; - a bottle receiving space, which is arranged in the housing and which is configured to receive a glass drinking bottle with a frozen drink for thawing; - a heating means, which is arranged in the housing and has radiant heaters, which are arranged around the bottle receiving space in order to radiate heat energy onto the glass drinking bottle during the thawing operation; - an electronic circuit, which is configured to detect whether at least one of the radiant heaters is defective, - a thermal insulating and cooling means, which is arranged in the housing, the thermal insulating and cooling means having: - a thermally insulating space, which is formed in the housing between the radiant heaters and an outer housing wall and so as to circumferentially encompass the outer housing wall; and - an air cooling, in the case of which cooling air is drawn from the surrounding area into the housing by means of an air conveying means via an air inlet and is conducted in the housing via an air duct to an air outlet, wherein the air duct is formed so as to encompass at least the thermally insulating space; - a thermally insulating space, which is formed in the housing between the radiant heaters and an outer housing wall and so as to circumferentially encompass the outer housing wall; and - an air cooling, in the case of which cooling air is drawn from the surrounding area into the housing by means of an air conveying means via an air inlet and is conducted in the housing via an air duct to an air outlet, wherein the air duct is formed so as to encompass at least the thermally insulating space;
