In EnergyPlus the system you describe can be modeled with the ZoneHVAC:LowTemperatureRadiant:VariableFlow (or :ConstantFlow) object. This object will reference heating/cooling coils which are attached to the respective plant loop demand branch with nodes as any hydronic coil would. It will also reference a surface or list of surface which define where in the space the panel is located (in this case, a ceiling surface). This surface must have a construction of the type Construction:InternalSource, which defines the material makeup of the panel as well as the dimensions of the tubes.
There is no explicit way of modeling biomass boilers in EnergyPlus that I'm aware of.

PS. This question did not specify OpenStudio, but for the record here is a good video explaining modeling and calibrating these systems in OpenStudio: http://youtu.be/6vMBXIM_yjU
