I don't know if people already do this, but I've started taking my damp/compressed sleeping bag out after a trip, zipping it up, and putting the hood opening over the floor vent of my heater at home.
This inflates the sleeping bag with warm air like a big wind sock, and does a nice job of drying out down and lofting it back up without the concerns of putting it through a dryer or when the weather doesn't allow sun-drying.
Anyway, just a thought that I figured might be usefull to others.

I think you have a pretty good idea. I'm going to have to give it a go.

Does your forced hot air heating system have a humidfier attached to it for humidifying the warm dry air? Just curious, as i'm thinking that the amount of humidity added to the warm air, while relatively low, is intended for dispersement throughout an entire room/home/apartment. I wondering how much of that humidity might remain in the bag's insulation (particularly if down bag) at the end. I wonder how much of the trapped humidity in the insulation will find its way out of the bag after the warm air stops blowing and the bag cools. I'm sure some will due to the temperature gradient (i'm guessing that the inside of the bag must get mighty warm).

Maybe a short 10min "Touch Up" tumble dry in the dryer afterwards to attempt to remove any remaining humidity might be in order?

I don't think I'm fancy enough to have a humidifier, and my heater doesn't exactly pump out super hot air, so I can leave it on and it ends up bone dry.
I suppose not everybody would have the same set up, but if it works for you, it's definitly a low-impact way to dry and loft the bag.
