There are two solar water heating technologies:
Solar thermal energy is the transformation of solar radiation into thermal energy. This transformation is used directly (to heat a building for example). The fundamental principle applied is to capture the energy of visible light through a black body.
On the scale of an individual or collective dwelling, it is possible to install a solar water heater: these are glazed collectors usually installed on the roof, in which a heat transfer fluid heated by solar radiation circulates which then transfers the heat to a water tank.
This process makes it possible to cover between 50% and 70% of the annual hot water needs (in France), and to possibly provide additional heating.
Solar thermal energy is collected by collectors and used by a heat pump to recover available calories. The solar panel also captures calories from the ambient air ( for more information on how a heat pump works, see how an Air / Water heat pump works)
Thermodynamic solar energy consists of a solar panel connected to a storage tank by a connection containing a refrigerant. The balloon is replaced by a thermodynamic system that recovers the calories transmitted by the fluid. The panel can be placed on the roof or on the facade.
This totally ecological process has proven its worth for more than 30 years and the figures prove it:
This product is eligible for the tax credit (2012: 32% alone and 40% in work packages).
This product is also eligible for Eco-PTZ (zero interest loan), if installed as a work package.
For example: if you install a heat pump with attic insulation or with a solar water heater.
You can combine the two grants if your income does not exceed 30,000 € per year.
Simple, robust and market-recognized solutions provided by: From Dietrich.
All configurations are possible:
New: the Solen solar water heater, it captures the heat present in the environment (rain, wind, sun……) and returns it to the thermosol block that heats the water in the tank.
Ecological, design and economical, it operates 24/24 360 days a year.

With the sun, you cover a large part of your family’s hot water needs for free. Solar energy is collected and converted into heat using thermal solar collectors. These heat a heat transfer fluid that circulates in the tubes and heats the hot domestic water. Everywhere in France, solar radiation is sufficient to operate an installation.
Inisol ensures you a quality and abundant supply of domestic hot water for a long time.
Extremely flat (70mm) equipped with black clips, the Inisol neo sensor is unique.
Integrated in the solar station or in wall mounting, Diemasol A guarantees you an intelligent and completely autonomous control of your installation.
