These French professional rules concern solar combisystems provinding space heating and hot water to renovated houses or existing houses with a new system.
The rules include three parts in three separate documents:
- The first part (121 pages) describes rules for the design and dimensioning of such solar combisystems (solar collector, water tank, pump, auxiliary heating source, hydronic circuit, controls, heat emitters).
- The second part (113 pages) describes rules for installation and commissioning of the system.
- The third part (63 pages) details rules for maintenance. These rules are the same as in new buildings.
These rules result from the French Programme "Règles de l'Art Grenelle Environnement 2012".
