  "textContent": "An electrical heating device for a motor vehicle has a housing which encloses a circulation chamber. The housing has inlet and outlet openings for a medium to be heated which communicate with the circulation chamber. An electrically insulated PTC element projects into the circulation chamber and is electrically conductively connected to conductor elements leading to connections of different polarity. The housing forms a connection chamber in which the connections to the PTC element are electrically connected. The connection chamber and the circulation chamber are separated from one another and are sealed against each other. A a flat tube is curved in a U-shape for a good heat discharge. The flat tube has opposite legs which each contain at least one PCT element and against which rests at least one heat-emitting element which is exposed in the circulation chamber.",
