Moving floor vent to toekick area
Hello. We are renovating our kitchen as well as baths and new flooring. Our house builder put the floor vents in several poor locations. There are two I'd like to move, but the one in the kitchen is the focus of this post.
The vent is currently just inside the door to the garage in the kitchen right in front of the built-in pantry. Vent runs perpendicular to the garage door toward the hinge side of the door. Vent runs horizontally to the (tiny) pantry just in front of the pantry door.
I am removing the (tiny) built-in pantry and replacing it with larger pantry cabinets. I'd like to move the vent 8-10" to under the cabinets and put a toekick vent on the front of the cabinets.
My GC says that usually people just have the vent dump into the space (plenum) under the cabinet and have the vent cover on the toekick. He says this isn't very efficient, and also heats up the pantry. I understand his point. (Is this a valid point?)
Is there a good way to do this venting? Could most of the opening under the cabinet be blocked off so it has a smaller opening to force the air out of the vent. Or is there a small 90 degree venting solution to connect to the toekick opening so the are is directed into the kitchen rather than under the pantry?
I've searched the internet, but haven't seen pictures or good ideas for this solution.
Thanks for any advice!
