I am retrofitting an old house with an HRV and cannot decide the best way to run the stale-air-ehaust.
Here's what I'm planning to do:
HRV located in basement of bungalow, run one 12"x3" wall stack up to the attic, and then, using a 12x3 to 6"round stack boot, spider 6" insulated ducting to the bathroom, kitchen, living room, and main bedroom using ceiling diffusers.
I also want to run a few diffusers to the basment.
I will be running the fresh air return through the existing furnace ducts.
Does this sound acceptable?
Will I achieve an adequate draw to the HRV using this method?
Please help me out with any suggestions or advice,
