I find that the documentation of the surface Component is a bit misleading :
For the FixedTemperature Component, the heat_sink parameter appears whereas it is not actually read, nor is the depth.
For the SlabOcean I would precise that the temperature is the initial temperature, as this can be confused with a fixed temperature.
What is the height parameter (especially related to the depth) is unclear to me also.
