# Software toolsHARPa, the app that estimates the energy class of old domestic boilers
Most heating appliances currently installed in European countries are old and inefficient. Replacing them with more energy-efficient and/or renewable technological solutions will help to significantly reduce greenhouse gas emissions and, consequently, the environmental impact on the planet
- English
HARPa was developed as part of the Harp research project, which ran from 2019-2022 with funding from the European Horizon 2020 programme. It is based on European Regulations 811 and 812 of 2013 and is dedicated to stand-alone domestic heating and hot water systems.
With a few simple data, HARPa calculates the energy class of the old generator and expresses it in the form of a label.
The update of the HARPa app, carried out by ENEA in cooperation with Assotermica - ANIMA Confindustria and Institute for Renewable Energy - Eurac Research, adapts the app to the national context, based on the results of the awareness-raising campaigns carried out between 2021 and 2022.
The HARPa energy label is a voluntary tool and does not overlap with the scope of the mandatory label.
