Hi Sandy-Eyed,
I wouldn't wrap your CPAP in a blanket. You might occlude the air intake and like any electrical appliance, you want to maintain air flow around it so that it doesn't overheat. How is your humidifier working now? Besides keeping the hose under the covers to keep the air inside warm, you can make a fleece hose cover or just buy cheap tube socks, cut the toes off and thread them on. There is also a hose with an internal heating coil that can be bought online. I know rainout wasn't your problem though.
