Heating system and method for operating said system

Abstract

The invention relates to a heating system and a method for operating said system, comprising a first and a second heating device ( 1, 2 ) and a common control unit ( 3 ), wherein the first and the second heating device ( 1, 2 ) is designed such that it can be operated with the same fluid fuel and that it can be controlled by means of the control unit ( 3 ). According to the invention, at least one time-dependent process parameter of the control unit ( 3 ) is intended and/or used as a calculation basis for determining fuel consumption values of the first and/or second heating device ( 1, 2 ).

1 . A heating system comprising a first and a second heating device ( 1 ,  2 ) and a common control unit ( 3 ), wherein the first and second heating device ( 1 ,  2 ) are designed so that they can be operated with the same fluid fuel and can be controlled by means of the control unit ( 3 ),
 wherein at least one time-dependent process parameter of the control unit ( 3 ) is provided as a calculation basis for determining fuel consumption values of the first and/or second heating device ( 1 ,  2 ).   
     
     
         2 . The heating system according to  claim 1 ,
 wherein one of the two heating devices ( 1 ) is configured as a combined heat and power heating device, in particular as a Stirling engine, for generating heat and power.   
     
     
         3 . The heating system according to  claim 1 ,
 wherein one of the two heating devices ( 2 ) is configured as a heating boiler for generating heat.   
     
     
         4 . A method for operating a heating system comprising a first and a second heating device ( 1 ,  2 ) and a common control unit ( 3 ), wherein the first and second heating device ( 1 ,  2 ) are operated with the same fluid fuel and are controlled by means of the control unit ( 3 ),
 wherein at least one time-dependent process parameter of the control unit ( 3 ) is provided as a calculation basis for determining fuel consumption values of the first and/or second heating device ( 1 ,  2 ).   
     
     
         5 . The method according to  claim 4 ,
 wherein the process parameter is integrated over the time and the fuel consumption value is determined from this and using a predetermined correlation.   
     
     
         6 . The method according to  claim 4 ,
 wherein an electrical power generated by a heating device ( 1 ) configured as a combined heat and power heating device is used as a process parameter.   
     
     
         7 . The method according to  claim 4 ,
 wherein a rotational speed of a burner fan disposed on one of the two heating devices ( 1 ,  2 ) is used as a process parameter.   
     
     
         8 . The method according to  claim 4 ,
 wherein a temperature measured at one of the two heating devices ( 1 ,  2 ) is used as a process parameter.
