Poorly designed ductwork - need opinions!
I have a fifth wheel with a heating problem. The duct feeding my bedroom is basically made of a sheet of 1/2" foam board taped across two aluminum floor joists. Both ends are capped off with foam board, and the space is fed by a flexible hose attached to the heater's distribution box. A neat idea, but kind of DUMB in its execution.
The foam board has warped and pulled away from the joists, so now there is no heat going to my bedroom and lots of heat going into the basement.
This makes DW very angry. Like, "Hulk Smash" kind of angry. We're going cold-weather camping next month, and I need to fix this before then or I'm a dead man. "D-E-D" Dead. She will stomp me flat and burn down the trailer if I let her freeze to death at night as if we were still tent camping.
What I'm planning to do is to get a rectangular to round 90 degree boot and attach it to the underside of the vent, then run galvanized round duct back to the flexible pipe from the furnace. I would then insulate the whole thing with some Roxul before putting foamboard back up across the joists.
I'd also like to replace the plain in-floor vent cover with one that allows me to partially close it (because it gets mighty darned hot in the bedroom if the ducting is working properly).
I am a jack of many trades, but HVAC isn't really one of them. Is this a good idea, or a bad one? Why? Other suggestions or helpful hints?
