Integration
Some preparations must be made and to meet certain requirements for the use of CHP. The CHP will be integrated into the heating water circuit. A properly dimensioned electricity and gas connection should be available. In new buildings, it would make sense to calculate the necessary space required by the CHP from the very beginning. Integration: hydraulic integration – electrical integration – spacial integration.
Hydraulic integration
The cogeneration plant can be incorporated into several variants in an existing new heating system. In combination with a conventional heating (oil or gas burner), the CHP will be installed. Here, the CHP is coupled to the return line, as shown in the hydraulic diagram. Thus, no additional control of the heating system is required, since only the return temperature of heating water is lifted from the CHP. In this way, the CHP is responsible for the base load and the conventional boiler for peak load boiler.
Easy Integration
Easy integration form for the CHP (PDF)
Version A: The CHP in series with the boiler, which is always through flowing. Without buffer.
Hydraulic scheme
Version B: As version A. With buffer.
Hydraulic diagram 2
Version C: The CHP in series with a boiler. A switching valve determines the flow rate through the boiler.
Hydraulic scheme 3
Version D: The CHP in parallel with a boiler with buffer. We encourage this version of installation!

Electrical integration
The CHP is connected via cut-outs at the main bus terminal or the main busbar. Multi-module systems often recommend a sub-distribution panel in CHP-room, but the modules can also be placed individually on the main busbar.
The cable cross-section and backup size is based on the number and type of cogeneration module:
A module ASV 21, 20, 15 and 14 requires a cross-section of at least 16 mm² and a hedge 3 * 50 A type NH 00th
A module ASV 30 and 40 requires a cross-section of 25 mm² and a hedge 3 * 80 A type NH 00th

Spacial integration
The space requirement of a cogeneration plant is an important consideration in planning.
The cogeneration module ASV 21, 20, 15 and 14, as well as the CHP ASV 30 and 40 has a footprint of 0.8 m x 1.20 m. The module should be set up with available access around the module for installation and maintenance.
We are happy to consult with you.
Up to 40 kW electrical cogeneration unit requires only one square meter of floor space. This base corresponds to a Euro pallet.
Position of ports
Thus, the CHP is immediately functional, additional ports are needed. The position of the connections are clearly shown in the PDF document.
