Project description

HARP is the acronym for “Heating Appliances Retrofit Planning”. It is a project funded by the European Union under the Horizon 2020 framework, and implemented in 5 countries (Portugal, Spain, France, Italy and Germany) by 18 partners.

The main objective is to motivate European consumers to plan the replacement of their often old and energy-intensive heating appliances with more modern and efficient systems. The stakes are enormous because more than 126 million central heating systems (boilers) are installed in the EU.

Why is this important ?

Heating and hot water represents 80% of the energy demand of EU households

60% of the heating stock consists of inefficient boilers (class C or lower)

Consumers are not informed about the efficiency of their installed heating systems


We have recently launched a survey to understand what motivates people to renovate their heating systems in France and Europe. We now need your answers.

The survey will only take a few minutes. Thank you in advance for your help and do not hesitate to contact us for more information!

Thank you for completing this short survey and help us transforming the heating systems market in France and Europe!


an application to contribute to the European energy transition

An online application will be developed shortly, called HARPa. One version will be for consumers, and another, more advanced, will be dedicated to professionals in the heating sector, so that they can advise consumers on the different alternatives that suit them best.

Users will thus be able to obtain a quick indication of the classification (on the scale of the energy label) of their already installed central heating unit, an estimate of the costs generated (in terms of energy consumption, maintenance, etc.), and a view alternatives available on the market by presenting their direct benefits (reduction of energy costs and consumption, reduction of CO2 emissions, etc.), as well as indirect ones such as the improvement of indoor air quality or noise reduction.

In order to facilitate the replacement of old heaters with more efficient and recent alternatives, the financial supports and incentives available nationally for each of the project partner countries will be listed in the HARPa application. The goal is to encourage and help consumers plan for the replacement of their heating system.
