Modelling and dimensioning a hot water floor heating system

The Centre Scientifique, et Technique du Bâtiment and Gaz-de-France carried out a comprehensive study for providing professionals with dimensioning rules for hot water floor heating systems. 
In the first phase we used a general purpose finite element analysis program called MARC and developed a three-dimensional mesh integrating the different floor heating components. 
In a second phase, simulation results were compared to an experimental result data set created for this study from a test cell specially dedicated to heating floor assessment. 
Finally, the numerical model was compared and validated against experimental results in both steadystate and dynamic regime.
