Heating device

Abstract

A device for heating a flowing medium (e.g., water), wherein the device comprises a heating module and a heat exchanger enclosed by an insulating material comprising a vacuum-packed core material. The heating module and the heat exchanger may further be received in a housing having a number of walls, wherein the vacuum-packed core material is arranged between one of the walls and the heating module and/or the heat exchanger.

1 . Device for heating a flowing medium, wherein the device comprises a heating module and a heat exchanger at least partially enclosed by an insulating material comprising a vacuum-packed core material. 
     
     
         2 . Device as claimed in  claim 1 , wherein the heating module and the heat exchanger are received in a housing having a number of walls, and wherein the vacuum-packed core material is arranged between at least one of the walls and at least one of the heating module and the heat exchanger. 
     
     
         3 . Device as claimed in  claim 2 , wherein the vacuum-packed core material comprises a panel arranged along at least one of the walls. 
     
     
         4 . Device as claimed in  claim 3 , wherein the panel is arranged along a substantially closed wall of the housing. 
     
     
         5 . Device as claimed in  claim 1 , wherein the vacuum-packed core material is at a distance from at least one of the heating module and the heat exchanger. 
     
     
         6 . Device as claimed in  claim 3 , further comprising at least one spacer arranged between the panel and at least one of the heating module and the heat exchanger. 
     
     
         7 . Device as claimed in  claim 6 , wherein the panel further comprises a reflective foil enclosing the vacuum-packed core material, and wherein the at least one spacer is substantially permeable to radiation. 
     
     
         8 . Device as claimed in  claim 7 , wherein the at least one spacer comprises a plate with a number of openings. 
     
     
         9 . Device as claimed in  claim 6 , wherein at least one of the heating module and the heat exchanger is fixed with bolts to a wall of the housing, and the at least one spacer further comprises a bush or ring arranged around at least one of the bolts. 
     
     
         10 . Device as claimed in  claim 1 , wherein the flowing medium is water. 
     
     
         11 . Device as claimed in  claim 2 , wherein the vacuum-packed core material is at a distance from at least one of the heating module and the heat exchanger. 
     
     
         12 . Device as claimed in  claim 3 , wherein the vacuum-packed core material is at a distance from at least one of the heating module and the heat exchanger. 
     
     
         13 . Device as claimed in  claim 4 , wherein the vacuum-packed core material is at a distance from at least one of the heating module and the heat exchanger. 
     
     
         14 . Device as claimed in  claim 4 , further comprising at least one spacer arranged between the panel and at least one of the heating module and the heat exchanger. 
     
     
         15 . Device as claimed in  claim 5 , further comprising at least one spacer arranged between the panel and at least one of the heating module and the heat exchanger. 
     
     
         16 . Device as claimed in  claim 7 , wherein at least one of the heating module and the heat exchanger is fixed with bolts to a wall of the housing, and the at least one spacer further comprises a bush or ring arranged around at least one of the bolts.
