The module provides the possibility of designing any heating system, including network and fitting sizing and hydronic balancing. Any kind of heating terminal (including fan-coils) is simulated by a ‘Receptor with known hydraulic resistance’. Together with the ‘Radiator sizing’ module, convective radiator systems can be designed. Together with the ‘Radiant systems’ module, the following radiant systems can be designed: floors, walls, ceilings. In combination with the ‘Panel systems’ module, modular panel systems can be designed. In projects with a common heat source for both convective and radiant systems, it is possible to use mixers or pump-mixing sets to obtain temperatures appropriate for radiant systems.
