Uncovered 18" clay tile piping with some kind of fabric lining. Any clues?

    Where is it located, under your basement floor?

    Underground preheat for combustion air, or free ground cooling? I assume it is perforated?

    There was an error rendering this rich post.

    18" diameter?

    Single pipe 392sqft system with an EG-40 rated for 325sqft and it's silent and balanced at all times.

    I don't know where you are located or how old the house is but in my neighborhood, there are some houses that have/had 18" to 24" tile piping that tied into a "network" that ran through the neighborhood. It was an attempt to provide some passive air conditioning to the houses that had a connection. There was a grate in the basement floor. I don't know if it was an experiment, back in the day, or if it was an option that a home builder had to pay a connection fee but only a few houses were connected. It probably didn't work well as the concept never evloved. Not sure how they kept it drained/dry. It certainly would resolve any question about having enough combustion air in the basement to support today's equipment.

    Do you know where the piping begins and ends?

    Where are you located? It's possible this was a conduit for an abandoned district-steam system.

    Some old houses that were new built with gravity hot air had the return air duct under the basement floor. It would gather cold air (around the perimeter of the house at the windows) and drop risers would connect to the underfloor duct. The "furnace beast" would then sit over the junction of the RA. The supply would then be the familiar "octopus" configuration.
    Have never noticed round tile out here though.
