About us

Created in 2015 by two entrepreneurs with complementary skills, newHeat relies on a multidisciplinary team and experienced managers to become one of the major players in the production of renewable thermal energy.

Our mission

Sustainable, local and competitive heat production

Heat is the first primary form of energy consumed in the World; it represents around 47% of the total. Today, 80% of this heat energy depends on fossil fuels.

The use of renewable energies as an alternative to fossil fuels is a priority focus for reducing CO2 emissions. Efficient energy savings combined with solar energy – an inexhaustible, competitive, and local resource – provide a lasting response to the sustainability of human activities.

Our job

Independent producer of solar heat and waste heat recovery

We offer two kinds of complete solutions to meet the expectations of each client

  • Solar heat "at the meter"

    Bearing the full costs of studies, implementation, and operation (third-party investment).

  • Turnkey EPC installation

    Combined with a full maintenance and servicing solution over time with guaranteed performance.

Our expertise

Modelling, engineering, and piloting

  • Modelling

    The precise modelling of our systems and their interaction with our clients’ processes and networks allows us to provide a suitable design and optimized operation.

  • Design engineering

    Our projects require extensive mastery of various technical skills: solar, hydraulic, thermal and automation engineering. These skills allow us to select the most suitable technologies for the operation of our clients' heat processes and networks, and for optimizing their design and set-up.

  • Control & command system

    We define and implement a dedicated and optimized management solution for each project, making our plants' equipment efficient and reliable, in coordination with our clients' equipment.

Thibault joined newHeat in 2018 as the head of development in France. Thibault graduated from the Ecole Centrale Nantes and the polytechnic University of Catalonia. He holds a master’s degree from minesParis Tech.

  • Nicolas Graveline
    Head of international development

    At the beginning of his career Nicolas worked on water treatment in France, Germany, Australia and Indonesia and has since 2011 switched his focus to energy efficiency and renewable energy production and on the means to get this type of projects financially viable (subsidies, carbon pricing mechanism, white certificates, debt, ESCO model…). Nicolas holds a Master’s of Engineering in Environment and Energy from the EPF engineering school.
