Old House Rehab - HVAC
Dealing with a very old house (late 1800’s) Joists are actual logs, and most framing in the house is 1x2’s. Right now there is an Oil burning forced air furnace in the basement that supplies heat to the first floor. This unit was installed in the mid 90’s. There is also an older (not used) fire based furnace that would have supplied heat to the first floor via the same ducts that was installed prior to the 90’s (don’t know when) The Oil furnace exhausts through a chimney that runs through the entire house , it is a concrete block chimney that is sealed in the wall on the first and 2nd floors, and exits through the roof. The wood burning furnace is no longer in use (but too large to remove through current basement door). The framing/plaster that surrounds the chimney on the finished first and 2nd floors, left a lot of empty space around the chimney (about 1ft in each direction), I can only assume this was because at the time, if/when the fire burning furnace was being used, the chimney could get very hot, and there needed to be enough space from the framing to account for that. Given that the fire burning furnace is no longer in use, I have the following questions. Can I reframe closer to the chimney to reclaim space for the first and second floors? Given that it’s just Oil exhaust running through the chimney, is there any risk in framing right up against the chimney today? Can I reroute my oil burning furnace exhaust directly outside of the house from the basement, and remove the chimney entirely? (This may actually be more work than its worth, as removing 30-40 foot of concrete block chimney inside your house sounds like a mess and a pain in the ass, plus I’d have to patch the roof where it exits, but I’m considering this option as I believe at some point in the future I will need to replace this furnace, and would like to size it with a unit capable of heating/cooling the upstairs in addition to the downstairs, this will require me to run trunk ducts (supply/return) up to the attic from the basement, and the best place to do this is in the spot that the chimney currently occupies, otherwise I’ll need to frame out and create some other linear space through the first/second floor. Appreciate the help, also we do have HVAC technicians coming out to quote a new system but likely wont’ replace immediately (heat works fine), but will ask the above questions as well, just looking for guidance from this group. submitted by /u/AlertImprovementTime [link] [comments]
