Electrical Heating Device with a Hold-Down Device

An electrical heating device comprising:

• a circulation chamber with inlet and outlet openings which are configured to receive a heat carrier;
• an electric heating assembly that is connected to the circulation chamber in a heat-conducting manner, the electric heating assembly being configured to heat the heat carrier in the circulation chamber;
• a connection chamber;
• a partition wall that is located between the circulation chamber and the connection chamber;
• and
• a control unit that is arranged in the connection chamber above the partition wall, the control unit comprising a printed circuit board for controlling the heating assembly;
• a hold-down device that is arranged on an upper side of the control unit;
• and
• a wall which is located above hold-down device and which closes an upper surface of the connection chamber;
• wherein the hold-down device is provided with at least one of
• a groove which is formed in an upper surface of the hold-down device and which is configured to collect condensed moisture and to keep moisture away from the printed circuit board,
• a roof surface which is formed in the upper surface of the hold-down device and which has a depression which is configured to collect condensed moisture and to keep the condensed moisture away from the printed circuit board.
