Venissieux, February 15, 2022

BOOSTHEAT (FR0011814938 / ALBOO), a French industrial player in the field of energy efficiency, and the CETIAT (CEntre Technique des Industries Aérauliques et Thermiques) announced to have signed a one-year renewable collaboration contract to support the development of the BOOSTHEAT Thermally Drived Heat Pump (TDHP) in various applications. A second measurement campaign was completed in mid-January and confirms the technical improvement path pursued by BOOSTHEAT as well as the efficiency of its heat pump in Domestic Hot Water (DHW) applications.

The collaboration contract signed with CETIAT perfectly illustrates BOOSTHEAT's commitment to work with expert partners from its ecosystem and to set up a regular validation process of its heat pump performance by an independent laboratory.

Indeed, not only will BOOSTHEAT benefit from regular measurement campaigns of its heat pump performance by an independent and recognized laboratory, but CETIAT's expertise will also contribute to the interpretation of the tested products' performance in order to accelerate their development. Finally, CETIAT will support BOOSTHEAT in the design and the improvement of its internal test laboratories in Venissieux.

This contract formalizes a process started a few months ago that has already resulted in two campaigns to measure the performance of the BOOSTHEAT thermal heat pump. During the second campaign at CETIAT, BOOSTHEAT presented a version of its heat pump specifically adapted to the production of hot water at high temperatures (≥65°C) for collective or tertiary buildings. Initial tests show a GUE efficiency of 148% for A7W15-65 conditions and 171% for A25W15-65, confirming the clear interest of thermal compression for such applications.

Since then, the company has initiated discussions with several leading operating companies to validate these performance levels in real-life conditions.

Éric LAMBERT, CEO of BOOSTHEAT, states:

 « I am particularly pleased to be founding this collaboration today, at the heart of the performance measurement of our products, near Lyon, with CETIAT whose expertise is internationally recognized. Our roadmap is moving forward according to plan... Not only is BOOSTHEAT today taking an essential step in its structuring as an "extended" company, but the latest performance measurements confirm the relevance to explore new targeted applications for our heat pump. »

Bernard BRANDON, CEO of CETIAT, states:

« This collaboration is fully in line with our mission to support our manufacturers, to enable the French HVAC industry to improve the reliability and speed up the development and marketing of innovative solutions. »
