What Is Tnf Treatment

Earth continuously receives solar energy in varying proportions. Today, we know how to collect and exploit this powerful energy.

Using solar energy is back up nature reserves and produce no emissions. Whether one is in Lille and Nice, solar radiation is sufficient to produce hot water and / or use it to participate in home heating and / or a swimming pool.

The innovative new range of De Dietrich solar systems allows many combinations to form a quasi-measure and optimize the performance of solar energy inputs.


  • In France, a year on average equivalent to 1000 kWh of solar energy available per square meter of roof.
  • Up to 60% of your hot water needs can be met by a solar system, across France and regardless of the region.
