3. An entertainment system according to claim 1 , wherein said entertainment system furthermore comprises a fluid monitor ( 1027 ) measuring fluid pressure of at least a part of said fluid system and in that said control means ( 1009 , 6 ) are adapted to perform said shutdown process based on said measured fluid pressure.

4. An entertainment system according to claim 1 , wherein said purging system comprises a gas pump ( 1011 ) pumping gas through at least a part of said fluid system during said shutdown process.

5. An entertainment system according to claim 1 , wherein said purging system comprises a liquid pump ( 1005 , 8 , 10 ) pumping liquid through at least a part of said fluid system during said shutdown process.

6. An entertainment system according to claim 1 , wherein said smoke generating means comprise a heating storage ( 4 , 304 ), which heating storage ( 4 , 304 ) comprises at least one first electric heater, which heating storage block comprises at least one flow channel ( 122 , 605 , 322 , 324 ) which flow channel ( 122 , 605 , 322 , 324 ) comprises a number of turns, which channel ( 122 , 605 , 322 , 324 ) has a length that at least is longer than the longest side of the heating storage ( 4 , 304 ).

7. An entertainment system according to claim 6 wherein said heating storage ( 4 , 304 ) is formed of at least two sections ( 106 , 108 , 306 , 307 , 308 ) which sections ( 106 , 108 , 306 , 307 , 308 ) are fastened towards each other by fastening means.

8. An entertainment system according to claim 6 , wherein a number of entertainment systems are operatively linked by communication means, whereby the heating elements are operating in time share mode depending on the actual heating demand.

9. An entertainment system according to claim 6 , wherein the rate of operation of said at least one pump is controllable by said control means dependent upon the temperature of the heat storing block.

10. An entertainment system according to claim 1 , wherein at least one of said at least one pump is a diaphragm pump used for pumping liquids.

11. An entertainment system according to claim 1 , wherein all internal systems components are powered from an internal power supply to allow software controlled shutdown irrespective of shutdown of external power source or the presence of AC network power.

12. Method of operating an entertainment system ( 1001 , 2 ), comprising the steps of:

supplying at least one flow channel of at least one heat exchanger of a smoke generating means ( 1007 , 4 ) from at least one pump that is ( 1005 , 8 , 10 ) connected to at least one container of smoke fluid ( 1003 , 12 , 14 ), directing entertainment smoke produced by said smoke generating means into the ambient area ,and automatically performing a shutdown process upon detection by a control system of malfunctioning of at least a part of said entertainment system, and wherein said shutdown process comprises the step of purging ( 2009 , 3003 a, 3003 b) at least a part of said at least one flow channel by pumping a fluid through the at least one heat exchanger during the shutdown process.

13. Method of operating an entertainment system according to claim 12 wherein said shutdown process is performed upon interruption of power ( 1025 ) to said entertainment system, and said shutdown process comprises the step of supplying power to at least a part of said entertainment system by a battery ( 1015 ).

14. Method of operating an entertainment system according to claim 12 , wherein said method comprises the step of measuring fluid pressure of at least a part of said fluid system and by performing said shutdown process based on said measured fluid pressure.

15. Method of operating an entertainment system according to claim 12 , wherein said shutdown process comprises the step of pumping gas ( 3003 b ) through at least a part of said at least one flow channel.

16. Method of operating an entertainment system according to claim 12 , wherein said shutdown process comprises the step of pumping liquid ( 3003 a ) through at least a part of said at least one flow channel.
