Hi all - 8 years ago I finished my basement. The heat pump heating unit/AC is gas heat. Next to it is my gas water heater. It was in what is basically was a hallway. We walled this off, but I put 12x18inch vents in the drywall high and low leading to the space where the HVAC/WH is. On the other end of that hall is a 12x12 room (unfinished). The room is open to this unfinished hall where the HVAC/WH is. There is a door leading to this room from my finished area, and I put a 2x2 foot vent in the bottom of it.
I vented it as such because there was concern about combustion/CO2/etc. I wanted air to be able to get to the HVAC/WH. The finished area outside this in my basement is about 1500 square feet or so. There is no venting to the outside. When doing this project 8 years ago, someone suggested maybe I run a breather vent of sorts to the HVAC area.
The HVAC/WH vent into what seems to be 4-6inch diameter tin double-wall that merges and heads out a stack in my roof.
I have had no issues in 8 years. I keep a Co2 detector nearby the HVAC. Never went off.
Now I want to finish that 12x12 room. I would basically be adding a door which would close off the HVAC/WH hall. I could put vents high/low in this door if needed. While the room would now be drywalled, etc., everything else is the same.
My question is whether this would somehow reduce airflow to the HVAC hall and choke it off, or cause other problems/CO2 issues, etc. While I've had zero problems in 8 years, I'm concerns that maybe there is just enough air getting to these devices, and added a door (although vented) could tip the scales.
Thanks in advance for your thoughts...
