Abstract:
A service water heating unit (2), provided for use in a heating installation, includes at least one heat exchanger (6), defining a first flow path (10) for a heating medium and a second flow path (12) for service water to be heated. The two flow paths (10, 12) are guided relative to one another in a first portion (A) in a countercurrent arrangement with directions of flow oriented in opposite directions, and in a second portion (B) connecting downstream, viewed in the direction of flow of the service water, in a co-current arrangement with directions of flow oriented in the same direction.
Abstract:
The invention relates to a service water heating unit (2), which is provided for use in a heating installation, comprising at least one heat exchanger (6), which comprises a first flow path (10) for a heating medium and a second flow path (12) for service water to be heated, and a first circulating pump (46) for the heating medium, which circulating pump is connected to the first flow path (10) of the heat exchanger (6) and is fastened on the heat exchanger (6), wherein a second circulating pump (76) is fastened on the heat exchanger (6) and serves as a circulation pump for heated service water.
Abstract:
The invention relates to a heat exchanger unit (2), in particular for the heating of service water in a heating installation, comprising a heat exchanger (6), which is formed as a plate heat exchanger, a first connector (26), which is attached to a first fluid connection point (20) of the heat exchanger (6), and a second connector (30), which is fastened on the heat exchanger (6), wherein the first (26) and second (30) connectors each comprise at least one identical base element (28) which comprises, internally, at least one flow duct (32, 34).

A service water heating unit (2) provided for use in a heating installation includes at least one heat exchanger (6), having a first flow path (10) in which a heating medium flows and a second flow path (12) in which service water to be heated flows, and a first circulation pump (46) which pumps the heating medium. The first circulation pump (46) is connected to the first flow path (10) of the heat exchanger (6) and mounted onto the heat exchanger (6). The service water heating unit (2) can also include a second circulation pump (76) mounted to on the heat exchanger (6), that pumps the heated service water.
Abstract:
A heat exchanger unit is utilized for heating service water in a heating installation. The unit includes a plate heat exchanger a first connector, attached to a first fluid connection point of the heat exchanger, and a second connector, fastened to the heat exchanger. The first and second connectors each include at least one base element. The base element of the first connector and the base element of the second connector have an identical configuration. Each base element includes at least two distinct flow ducts.
