[Shop-talk] Kitchen vent hood?

[Pat Horne]

True. Make up air can be a problem. For cooler climates there are heat exchangers that Transfer heat from exhaust vents (like the vent hood or fart fans) & add it back into exterior air being drawn in.

My stove hood has a fan in the attic that then vents out the side wall.  Definitely quieter.  They make different cfm models.  If you have a reasonably tight house and a fireplace or furnace, a big fan can reverse the flow in the flue and cause CO or smoke problems.  It's not usually a problem with typical consumer stuff, but if you want to suck pets into space like Jim, you should consider where the replacement air is going to come from.
