The innovation relates to a multi-boiler central heating system with a heat flow exchanger as a so-called hydraulic exchanger according to the generic term of the protection claim.

In heating systems with two or more heat generators, such heat flow exchangers have been known for a long time and form the prerequisite for functional, hydraulic relationships between the heat generators and heat consumers, i.e. only they enable energy-saving operation of such multi-boiler systems.

systems if the circulating water quantity in the heat generator is independent of the water quantity of the heat consumers.

The disadvantage of the previously known boiler systems with heat flow exchangers is that the devices themselves represent a complex and relatively expensive construction and their installation requires a lot of space due to the large amount of pipe assembly work that occurs when inserting such a hydraulic switch between the boiler system and the heating circuit distributor leading to the heat consumers. In addition, the known systems also have a high energy loss despite high insulation costs due to the many heat-emitting surfaces of the large amount of pipework.

The aim of this innovation is to simplify all of this considerably and to improve it both functionally and in terms of energy efficiency.

The solution to this problem is a heat flow exchanger

According to the generic term of the protection claim, this is primarily to be seen in the fact that the heat flow exchanger 1 with its heating front and rear connection pieces 2 and 3 is directly connected to the corresponding pieces

9 and 10 of the heating circuit distributor 7, 8 and has flow guide elements (ring diaphragm 4, retaining webs 5, impact plate 6) located in its interior 1a between the connection pieces 2 and 3 that narrow the cross-section; the guide elements 4 to 6 shown only as examples in the associated system sketch can, however, be replaced by any similar structural design that generates flow resistance.

In the sketch already mentioned, the arrow line P also indicates the flow state of the hydraulic switch when the so-called mass flow of the heat consumers is greater than the boiler water flow 1, while the line P ₂ shows the opposite situation.
