To add you need to use some care here.  If you scale the energy input you risk altering the W/m2 and therefore the system temperature. If you use the same W/m2 the overall flux may be different, but that also depends on how you scaled the flow....  If you want an interesting one to think through, what about mass flow and velocity: how do you scale those? 

Changing the reference also requires care as no one ever remembers to check it when viewing the results. It's also an easy setting to miss in a future case.Â
