HRV in Garage

[mnicholet]

Is it an issue to have a HRV (Heat recovery ventilator) in a Garage?

My understanding is, this can cause a carbon monoxide entry source into the home. Thank you.

Hi Mark,

I would call it out for the same reason that you have stated, nothing should draw air from the garage into the home as it could draw gasoline fumes, plus it is a clear breach of the fire wall.

I think the HRV can be located in the garage, since it's just the heat exchanger. It's the inlet for make up air that needs to come from a safe (exterior) area. I've seen HRV's installed... seems like 20 or 30 feet from the exterior wall in which the actual inlet was mounted. Intake duct ran from the inlet to the HRV, so the home was still pulling makeup air from the exterior even though the HRV was located at the interior.
But right... no make-up air from the garage.
