Heated tubing: Solo?
I was looking at the clinical manual for the AirSense 11, which mentions that the control of the heated tubing is separate from the humidifier controls. I've never used a humidifier, but I'm intrigued by the idea of trying the heated tubing to lessen the occurrence of "froze nose" in the winter.
I mean, at the velocity of air movement through the tube, I can't imagine it having that great an impact, but... this will not harm anything, will it?

When using the ClimateLine 11 tubing, it is detected automatically, and the Climate Control gives you an Automatic and a Manual setting. In the Automatic mode, you can control the tube temperature between 16 and 30 C. The machine controls the water temperature to give approximately 80% RH I believe. In the Manual mode, you can select both the tube temperature and the humidity level from off to 1 to 8 But I have no idea what that amounts to in RH levels.
I have always had the ClimateLine 10 and always used it, and always put water in the tank, so I have no experience with a dry machine.

The heated hose is used to make the interior of the hose warmer than ambient so that the moisture in the incoming air doesn't drop out of the airstream and condense on the hose. Think glass of ice water in the summer, condensation.
In used of my ResMed AirCurve 10 ASV, I've run the humidifier in manual mode, between 4-8 and heated hose at 80-86°F. I know the heat from the hose isn't really much warmer, but it felt more comfortable than if the hose weren't heated. I try to keep my sleeping space at 70-73°F at night. Some like living in a deep freeze bedroom and others live in a tropical bedroom. So all those variables means YMMV/your mileage may vary.

Thanks. I understand the "rain out" issue, and how the heated tubing assists with that. We tend to keep the winter temps inside no warmer than 65F, and my room is the most-exposed to temperature extremes. Plus, I have the PAP sitting on a box that raises it to ~6" off the floor. So, the air is colder, there.
