BOILSIM a supporting tool for helping the set up of guarantee of results (for boiler energy efficiency). 

BOILSIM the existing EU method for calculation of the seasonal (annual) efficiency of domestic boilers main target was up to now to allow a fair comparison of boilers, taking into account the installation and climate influence. So it was mostly used as a labelling tool. In order to extend the application of BOILSIM and to convert the program into a heating system diagnosis tool, it is necessary to perform further work.

The objective of the project is the validation and extension of BOILSIM so it can take into account the interactions between the different elements in a heating system. In other words to transform BOILSIM into a diagnosis tool for installers, designers, and architects. In that way, BOILSIM might be used in order to offer a guarantee of result to the consumer, when efficiency of the system is concerned. The objective of the project also includes the modification of BOILSIM with the necessary functions in order to facilitate the wide use of BOILSIM by as many types of users as possible. A sub-objective of the project is to involve new EU countries in the development of BOILSIM and implementation of the method.

The project is organised in Working Packages (WPs). The technical part (WP 1, 2, 3, and 4) aims at improving BOILSIM on the basis of 3 different, but complementary methods: the comparison with models (WP 1), with on-site test results (WP 2), and with emulators (WP 3). A new computer program will be developed (WP 4). The task of The information part (WP 5) is to make sure that the tool developed is adapted to most of the users in the EU and to make BOILSIM known to partners who do not know it yet (installers etc.).

Therefore, the consortium of the project consists of the partners having built up BOILSIM (for the development phase). New partners will help set up the specifications of the new BOILSIM.
