One of the novelties in the InstalSysytem 5 package is the ability to design a heating installation in which the main source of heat in the rooms are radiators supplemented, for example, with a heating floor in the bathroom. The heating floor can be supplied from the return of the radiator installation, which is a new feature compared to the previous generation of software (InstalSystem 4), in which it was possible to supply such a floor only from the supply pipe-run, i.e. with higher parameters.
