Venting air xchanger into garage. Good or Bad?

7 posts in this topic

I'm thinking about venting my air exchanger into my garage for some free heat. It still draws fresh from out. Any thoughts or concerns.

Not a bad idea don't know how much it will help. But think about where the stale air registers are. Probably in the bathroom D I smell some cross contamination.

There are no cold air return ducts in my baths, only heat ducts and fart fans

I was assuming your air ex was a fully ducted system. Yes by all means dump it into the garage. There may be some humidity but that is not a bad thing either.

Where does your HE pick up the stale air from?

The reasons for a air exchanger, is to replace stale, humid air, with fresh, dryer outside air, Unfortunately, you have to send some heated air out with the exhaust.

I dont think it is a very good idea to dump your exhaust into the garage. It will be too much humidity for the garage to handle.

The stale air comes from the cold air returns for the furnace.

I have my air x on a timer so it runs for 14 hrs at night and off for 10hrs during the day.

It's a Broan/Nutone Guardian Plus fresh air and heat recovery system. Controls options are low ventilation, high ventilation,(both bring in fresh outside air) or recirculation (inside air only).

I leave the control on low vent. and let the timer turn it on and off.

I would find it hard to believe you will generate enough heat to make a difference. If your going to go through with a "garage" project just put in a heater. wink
