RE: Arctic blast
It's perfectly safe. The hose itself doesn't get "hot", but the coils inside will hold the warmth and stop condensation.
The heated hose and cover made a huge difference for me.
RE: Arctic blast
I'm sure you're not melting a thing with the covered heated hose. Marshmallows, chocolate, butter.

RE: Arctic blast
+1 to the hose cover suggestion. I have one and it's one of the best improvements I've done. Another big improvement is a hose hanger / holder. Much, much better hose management that way.
And yes, even with a hose cover, you can still keep it under the covers if you wish.
RE: Arctic blast
I've been using a hose cover (again, get the 8ft one, the 6ft hose and 6ft covers do NOT match LOL) over a heated tube all year. Even at its hottest, it only gets slightly warm to the touch. It won't get hot enough to do any kind of damage.
RE: Arctic blast
desaturation thanks for asking these questions. The responses have taught me a lot.
RE: Arctic blast
Just thinking what I might do if in the same situation, and one thing that popped up was preheating the intake air just a little without warming the entire room. A coffee cup warming pad emits a bit of heat without noise and wouldn't be hazardous, but would it be enough to raise the humidity carrying capability of the air ? Do they make very low wattage space heating cubes ? (but they would have a fan which might be noisy on the bedside table).
