Help -- Heated hose too hot!!

meister · Post by **meister** » Sun Mar 06, 2005 3:11 pm

My Radio Shack adapter can be set at 9v, 10.2v, 12, and 13v.
What is the correct setting to use for this Aussie contraption?
My hose turns into a steam pipe and starts to cook my schnoz
like a Ball Park frank. Hopefully someone knows how to set this
thing to a cooler temperature. I better hear "No worries, mate!"
before my steam pipe cooks my entire air pipe like a sausage.
Right now I need to wake up and turn it off, but as the famous frog
experiment goes ... You can drop a frog into hot water and it
will jump out, but if you slowly raise the temperature on it during
the night, you will have some nice frog legs in the morning.

Meister,

I would keep that thing unplugged until you have the answer to your question. If your hose is heating up really hot, it isn't set correctly. If you keep it plugged you may hurt yourself and or burn your hose down.

Be Safe.

This is actually one of my concerns about the aussie heated hose. One of the reasons why our xPAP machines are so expensive is that they're so carefully regulated (this is also why we need prescriptions to buy them, right or wrong).

The AHH is not regulated in any way, and not even made within this country. Does that automatically make it suspect? Certainly not, and a lot of people have had great success with it.

But I'd be astounded if I heard anyone tell me that their heated humidifier could be set high enough to emit steam (assuming they bought one made by an xPAP manufacturer), while it's perfectly believable that someone might take one of those electric "hot pot" things, rig up a hose connector, and sell it as a cheap heated humidifier, and that could do great damage.

Caveat Emptor, as they say, or "CYA".

Liam, not intentionally casting aspersions on the AHH, just noting the difference between it and most of the rest of our xPAP equipment.

Unless the power supply is malfunctioning the hose can not overheat. Take your power supply back to radio shack and see if the electrical output is as it is suppose to be. The hose calls for 12V 1.0MA.

It is putting out 800mA. Is that 800 times to much?

The part number is 273-1631 at http://www.radioshak.com

Does the hose need DC voltage or a specific polarity?

On the back of the RadioShack box it says in bold letters. "THIS IS NOT A GENERAL-PURPOSE ADAPTER FOR RADIOS, TAPE PLAYERS, TV SETS, VIDEO GAMES OR OTHER EQUIPMENT."

I wonder, if laying there all night with my mouth taped closed, with my
ear plugs in, after a couple of sleeping pills, if the smoke pouring
out of the hose down my windpipe will wake me up.

Wader, it is 12v 1amp!! Not 1ma. You can use a supply greater than 1 amp, but you really shouldn't use one that is rated lower (like the 800mah one you have, that is equal to .8 amp)

I found that 12v made it too warm for me also. As the "Heated Hose" is only a wire element, you can use a lower voltage. By doing so, it will generate less heat. I use 9v 1amp myself. Give it a try. If that is too hot, then try 6v.

Mike,

You're right!!!! I typed too fast.

I use the 12V 1amp fixed voltage power supply and it works just fine!

I was just stating that from my non-expert, what the heck do I know, position

I think in the original post, the heat issue is one of a preference thing. IF the room is fairly warm already, the hose is going to make the air warmer. Personally I don't like the warmer air, (my asthma seems to like it even less ) So, the lower voltage works for me. The other variable in this is, how high you have your heated humidifier set. The higher it is, the warmer the air. Basically the goal of the heated hose is to raise the dewpoint. To do so it just has to raise the temp of the tube above the dewpoint. The amount of the heat generated by the 12v supply most likely raises the temp quite a few degrees above it. But, if all you are trying to do is stop rainout, try a lower voltage.

Course I am not a meterologist, so if you lower the voltage and still get rainout, blame the weatherman!

We live on a very frozen lake. We routinely get ice forming on the insides of
our windows, facing the lake, 'cause we keep the humidity up at
70%, when the temperature drops below 22 degrees outside. Remember we rarely see the sun in Michigan, as Lansing is the 2nd most cloudy city in the US.
We don't get much rainout in our hoses, we get more "snowout".
Turning down the heat on the humidifier is a good thing to try tonight.
Hopefully the ice crystals won't form on the inside of my FF mask
if I get it too low. One winter I had ice crystals forming in the corners
of my eyes when I was out shovelling. If you want to what Hell looks
like when it is frozen over, come up to the Great Lake State and visit Hell, Michigan.

Born in upstate NY, and raised in Michigan. No thanks, I gave that up and moved to the south.

With the heated hose, you really shouldn't have to turn down the humidifier...

Really suprised Liam didn't comment on the "heated hose"

they say to use a 12vdc 1.0 amp, but you can use less if it is too hot.

I use a 9vdc 800ma which is 3volt less and 200ma less than they suggest.

don't use an adjustable power supply, get one that is single voltage.

I am new to this forum, juat about 1 week now. I have been on a pap machine for about 3 years. I am trying to figure out the value of the heated hoses. I guess I am a bit thick. Can someone try to explain to me what the purpose or value of a heated hose is? I am most curious about it.

Thanks!

Joey

My heated hose came with a power supply (I just bought it a few weeks ago) and I found that it seemed too hot to me. I noticed, however, that all I needed to do is turn down the hot plate on the the humidifier (yes, I know this has NO impact on the heat of the hose) and the temperature of the air coming out of the hose seemed to be somewhat less.

I'm loving my heated hose now that I have the humidity adjusted correctly.

Joey, the reason I got my heated hose was to stop the "rainout". An added benefit is that it blows warm air (not hot), instead of cold air. Most of us enjoy that in the winter time.

To me, it feels like body temperature when it goes through the mask. But if I hold my hand over the hose - after it has preheated, then I can feel warm air coming out.

I also just got mine mainly to use occasionally on an unheated porch or this summer on a screen porch with the ocean wind blowing in off the Gulf of Maine. I tried it in the bedroom first and had to turn my humidifier down or off otherwise it was to hot. I haven't tried it on the porch yet.
