If you’re comfortable with metal working, cover up your old range hood vent using sheets of galvanized metal—the same material used to install flashing along a chimney. Your home center will have sheets or rolls of metal, as well as specialty tin snips for cutting. (If you need help check out these tips for cutting sheet metal.) If you’re looking for something with more of an antique flare, consider buying custom metal finishes to match your style.
If you have a huge family, and you indulge in commercial-scale cooking that requires a powerful exhaust fan, you’ll need to install a powered makeup air unit like those manufactured by Electro Industries of Monticello, Minnesota or Fantech. These units move a lot of air; in winter, the incoming air is cold, but it can be heated with 10,000-watt electric resistance elements if you want. Be prepared to suffer a huge energy penalty. The model EM-WH1025K from Electro Industries will supply 632 cfm at a 50 F° temperature rise. If you want a 1,200-cfm range hood, you’ll need two of these makeup air units; they cost about $1,800 each.
Some Passivhaus builders are experimenting with range-hood fans that don’t exhaust air to the exterior. Instead, they pull air from above the stove and pass it through a charcoal filter before returning the air to the kitchen. On the ceiling of the kitchen, in a location as far from the stove as possible, they also install a grille connected to the exhaust system of the home’s HRV.
