install.res is an EU project that aims at stimulating large-scale demand for heat pumps in existing buildings. In five different countries, alternative and innovative business and delivery models are tested, demonstrated and scaled-up to support a simple and affordable heat pump roll-out.

install.res focuses on the existing building stock since it holds the highest greenhouse gas reduction potential as most buildings still rely on fossil fuels for heating. However, it is not yet broadly known that developments in heat pump technology already allow for a very efficient and broad application of heat pumps in existing buildings. Modern heat pump can supply flow temperatures of 55°C with a very high efficiency which makes it possible to install modern heat pumps in existing buildings – often even without changing the radiators or retrofitting the building envelope.
The project deals with innovative, cost- and time-efficient delivery and business models for the installation of heat pumps in existing buildings. It thereby goes beyond the scope of just showing ways how to implement heat pumps but showcases how heat pumps can be installed faster and in a more simple and affordable manner.
In Austria, North Macedonia, Poland, Slovenia, and The Netherlands, install.res sets up demonstration project to develop, test and evaluate alternative and innovative delivery and business models for heat pumps. Such models aim at reducing barriers like high up-front investments, lack of financing possibilities or reliability risks for end consumers.
Building on the experience from the demonstration sites and knowledge from experts in the field, a set of dedicated and tailor-made resources (e.g. manuals, tools, guidelines and trainings) – the so-called fast-track schemes – are developed. These materials are intended to provide assistance in the areas of technical implementation, financing, communication and best practices. They will be integrated into established national and European platforms and training curricula for heat pump solutions.
The fast-track schemes are designed to enable implementers, end consumers and other relevant stakeholders in the building sector to roll out heat pumps at a higher speed than today and increasing affordability. This way innovative delivery and business models for heat pumps will become ready to be replicated across the EU.
