I agree. Hence my suggestion to put it all outside. Shop vacs are simply very noisy devices. I have a few of them and even the fancy ones are screaming machines. Unless you are running the vac for days, I'd bite the bullet and pay a little more for electric heat and put the noisy beast outside so your neighbors can think you are busy blowing leaves, at nite! :-)
Another thing to consider: Put the vacuum outside and pipe the exhaust back into the shop for less heat loss. If you go with 2" PVC there should not be much pressure drop. Also, I know some people run a wire through the PVC and ground it to avoid static build up.
