In tests that I ran last year, with one Fisher & Paykel HC-100 and one HC-150, with each of the devices set to maximum, both performed almost exactly the same, raising water from room temperature by about:
8 degrees C in 5 minutes
19 degrees C in 10 min
26 degrees C in 15 min
35 degrees C in 30 min
37 degrees C in 45 min and stable thereafter
This is indeed FAST and HOT. Simply as a matter of operating efficiency, the F&P humidifiers have a much larger heating plate area than the integrated units I've seen, and excellent physical and thermal contact with the humidifier chamber. ALL of the water in the chamber is directly over the heating surface (unlike some integrated units). The large volume held by the typical reservoirs, about 500cc, will generally last all night. The water surface area in contact with airflow remains constant, and is reasonably large, providing excellent humidification. The tray system provided by F&P holds most PAP machines and keeps everything organized and stable.
The HC-325 "disposable" chambers are quite inexpensive, and with care can last a very long time. Heavier and more durable HC-300 chambers cost a bit more and can be fully opened for cleaning (and are claimed to be "dishwasher safe"). I prefer the HC-325's over the HC-300 units, which can be a nuisance to pry open for cleaning.
Depending on your attitude toward emptying and drying after use, it does take some effort to get all of the water out of the HC-325 reservoirs. (I gently insert a threadbare washcloth most of the way into one of the ports, and then shake the reservoir, with the washcloth absorbing almost all of the water.) Keep the blue plastic caps that come with new HC-325's: they make excellent dust-covers when the reservoirs are not in use.
About the only thing these units don't do too well is travel as conveniently as the integrated humidifiers.
Overall, I think these F&P humidifiers are very impressively engineered. Add the plumbing right-angle adaptors recommended by 'rested gal' to your connector tubing, and they can't be beat!
