Heating Appliances Retrofit Planning

Motivate consumers to plan and replace their old and inefficient heating systems with a modern solution combining energy efficiency and renewable sources, accelerating the modernization of EU’s heating stock and significantly contributing to the compliance of EU’s energy efficiency targets.


Consumers do not think about heating until their system breaks down. When it does, the replacement is always an urgent process, hindering the possibility to look for the best solutions in the market and making smarter choices regarding a heating system that will likely be in operation for the next 20 years. In Europe, there are more than 300 million heaters (space, water or combi) that have, on average, been installed more than 20 years ago. Considering the heating energy label framework, market assumptions are that more than 50% of these equipments perform as C or lower. Old and inefficient, this is the status of the installed heating stock. Now is the time to act and raise consumers’ awareness about the opportunities of a planned replacement. Taking advantage of the energy label for space and water heating, we can mainstream the labelling concept to the installed heating stock, allowing to use a well-known support decision tool to communicate and motivate the consumer to replace its heating system with modern high-efficiency and renewable solutions. HARP accompanies the consumer decision process, providing an impartial message, based on the energy label and presenting the market solutions that respond to the consumer’s heating needs, providing a quantified approach for economic and non-economic benefits and bridging the gap
with the market providers and available national incentives. HARP is promoted by key knowledgeable partners in the fields of consumer behaviour, energy efficiency, heating solutions and business models, working directly with the consumer, or indirectly via professionals who are critical multiplying agents. Promoting dynamic efficient heating communities, where all the agents, from the supply to the demand side are committed to an efficient heating market, supporting the consumer to make smarter choices.
This allows HARP to build a solid concept that will succeed in the participating countries and within the EU reach.

Main Activities ADENE

Project coordinator at the EU level, responsible for assuring the sucessfull implementation of all activities, smooth coordination between all partners and the consortium’s relation to the European Commission.
Responsible for the definition of the national action plans and for the implementation of the national activities at the Portuguese level.

Key Deliverables

• Two methodologies to label existing space heating and DHW solutions, in line with the EU labelling regulations,
• HARPa, an online app that provides the energy label of the installed heating solution and an overview of heating solutions on the market and potential savings, raising consumers awareness to their replacement needs and possibilities,
• Consumer engagement resources focused on energy efficient heating (videos, seminars, social media, gamification, etc.),
• A toolbox aimed at professionals (namely energy experts, installers, system designers, retailers), providing a training programme on how to interact with the consumer and promote efficient heating solutions as consumer advisor,
• Experiences and best-practices gathered from the roll-out of activities with professionals and consumers,
• A policy integration scenario for the uptake of these results at the participating countries regulatory context level,
• Recommendations for the implementation of the labelling methodologies for installed heating systems at the EU level and in specifically in non-HARP-participating countries with case studies analysis,
• A direct interaction towards the definition of new financing programmes that can build upon the experiences and tools developed within HARP.

Portuguese Deliverables

• HARPa, online tool,
• Consumer engagement resources,
• Professional toolbox and training materials,
• Policy integration scenario adaptated to the Portuguese energy efficiency policy framework.
