HB Specify Position of a Heating System within a Room

Hi,

I would like to simulate and create a thermal map of a room, in which a Radiator is placed in the middle of it (to show, how much the temperature drops towards the walls). However, I can’t find a way to do so with Honeybee, as the HVAC systems are always applied to the whole of a room and cant be placed more specifically.

Is there any way to do such a simulation/specification of the heater-position or do I have to use additional/other tools?

Deeply appreciate any Inputs or Ideas!
