Philips Respironics DS400S M Series Pro C-Flex

I've been using a Philips Respironics DS400S M Series Pro C-Flex machine since January 2008 which also has a heated humidifier with a water chamber. What I don't remember when I first started using this machine was if the air coming through my hose to my mask by the time it reached my face was heated or not. The humidifier I assume still works because I fill up the water chamber each night to the black fill line and when I check it the next day the water level has gone down. I have been setting my humidifier dial to 3; it goes from 0 to 5.

If anyone on this board has this same machine with the integrated heated humidifier; when using the machine at night with a standard 6' hose; not a heated one; can you tell or feel the air coming through your hose and to your mask is warm or only room temperature? I spoke to CPAP.com yesterday about purchasing one of their heated hoses; the rep in customer service told me none of their heated hoses would work on my machine; I'd have to buy a new machine.

I usually keep the central heat in the house set on 72F at night because I don't like it hot at night and I was told by my original DME back in January 2008 when they delivered my machine and set it up for the first time that the air coming through the hose and to my mask would be the same as my bedroom's temperature. Could my machine's heated humidifier be going bad since my machine is now 6 years old? I planned to call Philips Respironics yesterday but I waited too late to call but I will try to call them later today to ask them this question.

The Hybernite heated tubing system would work with your machine:

The user guide mentions it is compatible with M Series humidifier. For some reason, the Hybernite is not recommended for PR Series 50 machines running software versions lower than 1.24, but that seems to be the only contraindication.

I have read that M Series users have used the Aussie heated hose, so I don't see why the Hybernite wouldn't work.

I used to use a PRS1 without heated hose, and if the temperature in my bedroom went below 70 the air would feel too cold on my nose.
