Hose Melted!!

1. Is the big square heavy plug thing supposed to get hot when in use?
2. Is it okay to plug this big thing into a power strip or should it plug directly into the wall. (The lamp, cpap, and hose are currently plugged into the power strip. Mistake?)

I checked and the big heavy power supply thing has a "UL" approval on it, but there's nothing like that on the actual heated hose.

Thanks!

Based on the original post ... seems it was the hose that melted, not the power adapter. In other words, the power adapter may well be "UL" certified but that certification may not apply to the heated hose iteself.

They already did. That's why we buy them from Australia and they don't make them here.

Difference in the Pur Sleep case is that it was being made and marketed here.

blarg, I'm lost (not unusual). Can you explain? (Or are you joking.) I know there is some type of heated hose thing for some of the F&P machines (hose sold on cpap.com), but that might be different.

I have 2 of them, one I purchased over a year ago and one I purchased a month or two ago. They both are still working.

However, I don't use the power supply recommended or that it came with. First one didn't come with a power supply and you had to obtain it in the states. The 2nd one I got came with the 1AMP x 12VDC power supply. It is huge.

Where I live it gets cool but not cold, so I found a 1AMP x 12VDC power supply to be too warm. So to run it cooler, I found in my junk drawer a 9VDC x 800ma power supply with same plug connector (came off an old Linksys router) and I have been using it nearly every night in the winter. I have the power supply on a digital timer, it only runs from 12AM to 6AM daily. I don't even keep track when it is on or off.

So far, my hose(s) have been working fine with the lower voltage power supply. I suspect the problem is with the new chinese made power supply, if it was getting hot, it means it couldn't handle the resistance of the hose, if it over supplied power it would melt the hose.

All the workers came to the Us for free health care.

Mexico went on Siesta Daylight Savings Time, and now only work 2 hour days, so production has dropped.

Most of the work force is at the Y.M.C.A., taking swimming lessons. Jim

Well, I dunno what the specific story is, but you can't straight up buy heated hoses here unless you get that F&P machine. I was more joking than anything.

Bump. Still curious if any one else had this happen and what solved the problem.

Me too. Especially since I have two heated hoses.

Since Ellie and I (at least) had almost identical experiences, my recomendation is that you consider not using the power supply which came with the hose. I also believe that the fact that we both had the failure within a few weeks of getting the hose may mean that it is a failure which shows up in "infancy" of the power supply and if you haven't had the problem you might never have it. I don't think there is anything wrong with the hose.

I'm going to order another hose and I'll use the radio Shack power supply I got to replace the original one.

Just my 0.02 as an effected user (who loves his heated hose too).

TerryB, did you get the same type of power supply at Radio Shack, or something different?

Pam

TerryB · Post by **TerryB** » Tue May 08, 2007 10:02 am

I guess you'd say it is the same type in that it is a wall plug in transformer in a single case. The output is to a cord which accepts multiple plugs to connect to the load. I took the old supply to the store to find the right size plug. Voltage and current rating are also similar if not identical.

TerryB

Remember that the original power supply overheated the heater coil wire before dying. Although the hose is damaged, it still has no appreciable leaks. I expect it to fail from fatigue where moved around the humidifier connection or where coming over the headboard. I guess I should get busy and order the replacement before I have a failure and have to put up with rainout again.

It's been over a year since the event, but my recollection is they said, more or less, Nah, can't happen, we run a hose and power supply night and day have never had one overheat. I'll look back into the emails and get some more direct quotes, but as I've said, I think the failure was in the power supply/transformer.

Terry, I got my first heated hose about a year ago and it didn't come with the power supply. I had to buy it from Radio Shack.

So, are you saying that you and Ellie got your hoses about a year ago and they came with the power supply? And you think those original power supplies are the culprit?

Oops, just reread and see that Ellie has only had her's a short period of time.

Here is the exchange with Donald,
Note time frame from shipment Late April to failure late May to disccovery of coils penetrating hose late Jun.

I'm going to order a replacement hose right now.

I was rinsing out the other day and I lookedin the two ends and found heating coils visible inside the hose at oneend and not the other end. Does this mean that I have managed tooverheat the coils and melt them through the hose and that the hosewill fail soon in this area? I suppose it could also mean this is theway the coils are anchored so they dont change position. If it is asign of overheating then I am concerned about my ability to use theequipment safely as I know that some nights I decide to remove the maskfor a while and I forget that I should unplug the hose. On the otherhand could it be that the failure mode of the first transformerprovided too much current and fired this area?

I hadcondensation problems last night a first since receiving the HH, andupon checking I believe the power supply has failed. I read no voltageon the output. The hose is reading 6 ohms DC resistance. I hope youcan verify that this is correct for the hose as I will go and get aRadio Shack Power supply if the hose is not the cause of the powersupply failure. Since I see less than 1 Ohm output winding resistance,I believe the transformer secondary has shorted in the power supply.
