      Adding thermal capacitance to the model itself would involve
    changing the source code and asking for some additional parameters
    so that you would be able to solve the first order differential
    equation that describes the behavior.  You'd need a Fortran compiler
    in order to modify, recompile, and relink the code into a modified
    component. You would also need to change the proforma.<br>
    <br>
      Another method that you could use to accomplish something like the
    same effect without modifying the source code would be to put a tank
    model (Type534 ideally) either directly upstream or directly
    downstream of the boiler. This would at least account for the
    thermal capacitance and standby losses of the liquid volume
    associated with the boiler.<br>
