If you're using a current release they should be the same (user error permitting), in an older version of the code there was a glitch. I'd need to see images of what you have selected when reporting & the results. 

I can't comment on the HTC reference. It's entirely dependent on how you want to report the value. My approach is to compare the heat flux per area (W/m2) if looking at experimental data.
