Ooops--just an oversight. You're right. But I do prefer to shorten
the original posts up so it all looks neater and simpler... sometimes
it takes more time to scroll down and find the actual new response--and
what a disapointment when you actually read it... hehehe

Peace, Dan

Yep - similar situation. The input vent would still run from outdoors. Just
thought I might be able to dump the exhaust into the vented garage.

Sorry - I said vented into (ie exhausted), not sourced from. The ERV input would
still be from outdoors.

I still don't like the sound of it--I'm no airflow expert, but you
would have some resistance to the exhaust? How much airflow out of the
gargage vent compared to the forced-air flowing from the ERV? There
would be a two different lengths of duct for in and out too... not sure
if that makes a difference? But I don't understand the motivation....
Are you trying to heat up the garage a bit? It's vented??

I still say you run two lengths across the garage to the outside and
terminate with a "tandom" connection (both go into one connection with
a cap that separates in and out). Very tidy and seems to be working
great in my case.

Peace, Dan
