An assistant has been added in generic DHW systems to calculate and import the value of the average seasonal performance of combustion boilers according to the UNE-EN 15378 standard. Two of the methodologies included in the standard have been implemented. On one hand, users can choose a value of the average seasonal performance by default, which depends on the fuel, age and type of boiler (Table B.3 UNE-EN 15378). On the other hand, the boiler cycle method (Annex N UNE-EN 15378), can be chosen, which provides a more accurate estimate if technical and equipment consumption data is available.
