Thermal solar technology


The best of the thermal solar technology for sustainable installations



For more than 20 years, 2ES has developped a competence in the design and the realisation of building integrated thermal solar solutions. 2ES is focused to fulfill the real energetic needs of the buildings. The sizing of the installation and the usage patterns are optimised in order to be coherent and integrate the thermal solar into the buildings energy mix.

2ES performs the design and sizing of the installation, the selection of components, calculation, energy production simulation and installation.

2ES has always striven to achieve installations that meet the need of the building from an energy point of view.


Always striving to blend aesthetics and functionality, 2ES takes care to work in collaboration with European technology leader solar collector manufacturers.


In addition, 2ES has developed an unique solution : the controlled thermal solar – STC ®


This solution comes with a simple and secured technology that ensures an optimum production related to the heating and domestic hot water needs .

This solution ensures several advantages :


  • An auto-drain feature means that there is no risk of overheating of the solar thermal collectors


  • An easy and fast restart of the total installation


  • A minimized energy consumption of the whole system


  •  A low maintenance thanks to an enhanced life cycle for pumps valves and pipes.
