A central heating plant having a principal heat source and a make-up heat source which can operate simultaneously. A series of principal heat diffusers are connected in parallel and arranged to be supplied with heat-carrying fluid from either or both of the heat sources, and a series of make-up heat diffusers are connected in parallel and arranged to be supplied from either one or both of the heat sources. The two series of diffusers are arranged to be supplied with heat at the same time, separately, or alternately. The principal source is a low-temperature heat source arranged to supply the series of principal diffusers via a first mixing cylinder; the make-up source is a high-temperature source arranged to supply the series of make-up diffusers via a second mixing cylinder; and, the first and second mixing cylinders are joined by a double connection so that each can supply the other, with the arrangement being such that the principal heat source can supply the series of make-up diffusers via the first mixing cylinder and then the second mixing cylinder, and that the make-up source can supply the series of principal diffusers via the second mixing cylinder and then the first mixing cylinder.
A central heating plant comprising a principal heat source and a make-up heat source which can operate simultaneously, a series of principal heat diffusers connected in parallel and arranged to be supplied with heat-carrying fluid by one and/or the other of said heat sources, and a series of make-up heat diffusers connected in parallel and arranged to be supplied by the one and/or the other of said heat sources, in which the two series are arranged to be supplied with heat at the same time, separately, or alternately, the principal source is a low-temperature heat source arranged to supply the series of principal diffusers via a first mixing cylinder, the make-up source is a high-temperature source arranged to supply the series of make-up diffusers via a second mixing cylinder, and the first and second mixing cylinders are joined by a double connection so that each can supply the other, the arrangement being such that the principal heat source can supply the series of make-up diffusers via the first mixing cylinder and then the second mixing cylinder, and that the make-up source can supply the series of principal diffusers via the second mixing cylinder and then the first mixing cylinder.
