Should I be alarmed about a cardboard & Styrofoam-lined intake vent?


We purchased a house about 3 months ago. It's a 1955 ranch-style - some bits are modern and some are 1955 original. While painting a while back, I removed the heating intake vent cover (I assume that's what it is - it's covered by magnetic panels at the moment), and saw the image below. I'm not sure whether that's what things are supposed to look like and I'm looking for a "that's pretty standard," "that ain't great but it ain't a big deal for now," or "holy nuts - what fool installed that?"

This area is at the main level ceiling - just below the attic. The metal HVAC line runs about three feet below this image and just terminates, open-ended, in the middle of a 2' x 2' shaft that runs from there down the basement ceiling, just above the boiler. A few electrical cords use that shaft as a conduit. The shaft is also home to a 1" water pipe that is connected to nothing whatsoever.

Our house has oil heat/water boiler/baseboard radiators. It has a totally separate central A/C system.

Thanks.

The previous owner's husband, who passed in 2000, seems to have fancied himself a DIYer.

That shaft just ends as an opening above our boiler/furnace (which has a separate and actual vent stack). One of those two cables just stops halfway down - with exposed wires and all. I need to figure out what the purpose of this odd opening was in the first place.

If I can see loose fill insulation from the attic, then I've presumably got a pretty major air leak here.

Below that mess, there's this shaft:

Above that mess, that metal conduit just ends:

So, apparently, this is simply a pointless shaft that houses a pointless length of old rigid heating conduit which has a pointless hole cut into it which lines up with a pointless space covered by a pointless vent cover. The shaft is also home to a pointless water pipe that connects to nothing on either end, one live cable, and one dead cable.

But why, previous owner who is now deceased, why?
