Apparatus for heating service water

Abstract

An apparatus is described for heating service water with a solar collector, comprising a service water tank ( 7 ) with a partly cylindrical jacket ( 8 ) as an absorber and an enclosure ( 1 ) which covers the service water tank ( 7 ) and forms a translucent cylindrical jacket ( 3 ), the axis of which extends parallel to the axis of the jacket ( 8 ) of the service water tank ( 7 ). In order to provide advantageous heating conditions, it is proposed that the service water tank ( 7 ) is connected in a thermally conductive manner with an absorber plate ( 4 ) forming a bottom part of the enclosure ( 1 ) and that the absorber plate ( 4 ) and the jacket ( 8 ) of the service water tank ( 7 ) are covered with a wide-meshed, thermally insulating fabric ( 11 ).

1 . An apparatus for heating service water with a solar collector, comprising a service water tank ( 7 ) with a cylindrical jacket ( 8 ) as an absorber and an enclosure ( 1 ) which covers the service water tank ( 7 ) and forms a translucent, partly cylindrical jacket ( 3 ), the axis of which extends parallel to the axis of the jacket ( 8 ) of the service water tank ( 7 ), wherein the service water tank ( 7 ) is connected in a thermally conductive manner with an absorber plate ( 4 ) forming a bottom part of the enclosure ( 1 ), and wherein the absorber plate ( 4 ) and the jacket ( 8 ) of the service water tank ( 7 ) are covered with a wide-meshed, thermally insulating fabric ( 11 ). 
     
     
         2 . An apparatus according to  claim 1 , wherein the fabric ( 11 ) consists of a glass-fiber fabric. 
     
     
         3 . An apparatus according to  claim 1 , wherein the absorber plate ( 4 ) accommodates the service water tank ( 7 ) in a cylindrical bulging portion ( 6 ) sitting close to the tank jacket ( 8 ). 
     
     
         4 . An apparatus according to  claim 1 , wherein the service water tank ( 6 ) is composed of a jacket ( 8 ) which approximately forms a semi-cylinder and a cylindrical wall ( 12 ) which is connected to the inside of the jacket ( 8 ) and whose axis extends perpendicularly to the jacket axis. 
     
     
         5 . An apparatus according to  claim 4 , wherein the jacket ( 8 ) of the service water tank ( 7 ) is integrally arranged with the absorber plate ( 4 ).
