This online tool for “calculating package efficiency and class” is under development. It is available online as a test version in order to allow users to try it out and provide feedback about the tool to the Labelpack A+ consortium. This feedback can be sent by e-mail to info(at)estif.org.

The use of this calculation tool is free.

Professionals using the tool are responsible for the use they make of the calculation provided or of the energy label for packages and fiche generated with this tool.

General users must confirm the results of the calculation with professionals specialized in the installation of heating systems.

This online tool has been developed by the Labelpack A+ consortium based on a tool made available by the European Commission: “Tool for calculating the energy efficiency of packages of heaters, water and combination heaters”, developed in an excel spreadsheet.

You can download it here:   

More information about the EU energy labelling and ecodesign requirements for space and water heaters in households can be found in other sections of this Labelpack A+ website or in dedicated section of the European Commission website:

Information regarding the calculation for solar devices’ target

The calculation of packages including solar devices require two parameters:

  • Annual non-solar heat contribution (Qnonsol)
  • Auxiliary electricity consumption (Qaux)

When not provided by the equipment supplier, these parameters have to be calculated. These can be calculated used the so called “SOLCAL” method. The Labelpack A+ tool shall incorporate a module for the SOLCAL calculation. In the meantime we suggest the use of the following tool (excel file):
