So you did not blow up the water pump or plug the core without coolant? All sorts of catastrphic tales on the web.
The only caveat that comes to mind is that with solely distilled water & cleaner in the system, this obviously isn't something you want to be doing when the temps are literally freezing cold.
Other than that, no doom & gloom -- actually, quite the opposite experience here. My F-150 wasn't exactly meticulously maintained prior to my ownership, and among the issues...zero heat. With distilled/cleaner in the system, whatever blockage was there dislodged, and excellent heating was restored!
