Global environmental evolutions are creating new business opportunities and generating technical challenges which require both agility and global innovation.

We consider time-to-market to be a strategic asset and we invest continuously to actively contribute to our customer’s success.
We have demonstrated this with the introduction of new solutions such as the first hybrid electronic control in Europe, a patented solution with embedded smart algorithm, as well as the first plug & play intelligent controller for heat pump water heater.



Cotherm global R&D strategy is to permanently develop our technical expertise by anticipating economical and social environment evolutions and by positioning technologies in business perspectives. We design technical platforms ready to be implemented and adapted to our customer products in a timely manner. Special attention is given fluent, transparent and long term collaborations in order to establish the confidence with our partners and create the conditions for project success.





The technology environment is becoming more and more complex from new materials to network connectivity. In order to create innovative products and maintain an up-to-date technology expertise, it is necessary to acquire knowledge from various domains and technology partners. As a result Cotherm actively invests and contributes to a variety of advanced collaborative research programs. These include new materials, heat pump technologies, home automation system, smart grid and connectivity.

Cothem has been selected by the French Ministry of Industry to participate the COMETE program. The aims of the program are the study and implementation of cloud services, and product solutions for comfort and energy efficiency in dwellings. Other partners in the program include:



In addition, Cotherm is an active member of professional and public organization to provide our expertise in different application field as sanitary hot water, heat pump water heaters, and space heating. More recently, Cotherm was invited to participate in new collaborative programs in the area of smart grid development standards.


We constantly seek to contribute to collaborative research with new potential partners as a permanent effort to continue innovating with industry leaders.



As expert in water heating and space heating, Cotherm offers product performance qualification services in advanced laboratories based on major international standards. Laboratories represent more than 50% of our R&D investments and allow us to make performance qualifications, provide conformity to standards and guarantee real energy savings which are the basis for our products and solutions.

In the collaboration with our customer and partners, laboratories play a key role in the R&D project and we permanently benchmark our results with partner laboratories which recognized as major international organizations. As examples, our laboratories cover expertise in the field of water heater (EN 50440, EN 60335-2-21), heat pump water heater performances (EN 16147), space heating (EN 60675) for measurement of product reliability, safety and energy savings.




Energy efficiency is the new dimension added to Energy Related Product (ERP) and, as such, from the origin of the European commission project to introduce energy a new label, we anticipated committed significant investments in training, ecruitment, equipment, and product development.

Cotherm is now recognized as the independent expert in Energy labeling and ecodesign for water with more than 400 products of different sizes and materials tested in our laboratories.
