Venissieux, December 7th 2021

BOOSTHEAT (FR0011814938 / ALBOO), a French industrial company in the field of energy efficiency, has announced the expansion of its partnership with DALKIA to include the development of a high-temperature heat pump based on thermal compression for water heating. A first field test is planned for the beginning of 2022.

Over the past decade, the regulations that Europe has put in place to meet its CO2 neutrality targets for 2050 have made buildings increasingly energy efficient in both renovated and new homes.

As a result, the energy consumption for heating drops significantly and that for hot water preparation, among other things, takes up an ever larger share.

The actors of the energy transition are now more interested than ever in improving the performance of water heating systems by integrating renewable energies and optimizing production. The recent and future energy price increases are encouraging the entire residential and commercial construction industry to consider these new solutions that guarantee energy savings and a reduction in their carbon footprint.

DALKIA is a historical partner of BOOSTHEAT, with whom it has been working since 2013 on issues relating to the heating of communal houses, tertiary and public buildings. BOOSTHEAT is now expanding its partnership to develop a heat pump intended for the production of hot water at high temperature.

BOOSTHEAT, a manufacturer of energy-efficient solutions, is working on the development of a high-temperature heat pump whose thermodynamic circuit is provided by the company’s patented thermal compressor.

This solution uses a natural refrigerant that has no impact on the ozone layer and negligible impact on the greenhouse effect with a global warming potential[1] of 1. It also has thermal properties that are particularly good for generating heat at high temperatures, making the solution ensure anti-legionella thermal shock while maintaining a high level of performance.

After the optimization phase of the current solutions in the laboratory, which began in September 2021, BOOSTHEAT is expected to carry out a field test in early 2022.

Eric Lambert, CEO of BOOSTHEAT, explained:

“DALKIA and BOOSTHEAT have been working together for a number of years on integrating our heating solutions into“ apartment buildings ”. oriented approach perfectly matches our roadmap announced last September, aiming to expand the scope of our technology beyond residential renovation, DALKIA brings us its industry knowledge, high standards and determination to be robust and profitable to see energy efficient Solutions are created quickly, we live up to your trust. ”


BOOSTHEAT was founded in 2011 and is active in the field of energy efficiency. The company’s mission is to accelerate the energy transition by integrating its technology with energy-intensive applications. BOOSTHEAT has designed and developed a thermal compressor protected by 7 patent families that significantly improves energy consumption in order to promote sensible and appropriate use of resources.

BOOSTHEAT has its headquarters, research center and production facility in Vénissieux, near Lyon (historically an HVAC * industrial area). The company holds the Entreprise Innovante (Bpifrance) and French Fab labels. The BOOSTHEAT share is listed on Euronext Growth Paris (ISIN: FR0011814938).
