MATLAB: Customizable Hot airblower Model

airheater modelfanSimscape

I'm trying to design a customisable airheater model. In doing so I've broken up the model into subsystems i.e the heater, fan,pipe.
For the heater I was wondering if some assistance can be lent on how exactly to model a heater in simscape where air from the enviromnemt passes through the heater in which the air is heated, then is blown by the fan through the pipe. I'm considering using the convection and conduction block in simscape to develop the heater.
