Best practices for ERV register locations and vent hoods
My ERV plan is to use a dedicated duct system to bring supply air (fresh air) into the rooms near the ceiling. This makes sense to me so cooler air can mix with conditioned air from the mini-split. I would have the return air register about a foot up from the floor. I read that most installations have both supply and returns near the top of the walls. This would make for longer duct runs. Is this recommended?
I’m ending up with more penetrations through the envelope for ERV, bath fans and dryer venting than I would like. All have built in backdraft dampers. (I don’t think the dryer does) What is recommended for a product or method to improve air sealing the outside air openings? Good vent hood products, another damper?
