Just about all of the new homes I photograph power vent the furnace and hot water heater out the side of the house. Anyone that has a foursquare with a chimney going straight through their house could benefit greatly by using one of these including myself. I'm trying to find out the downsides of using such a contraption. I asked this question to the Fine Homebuilding podcast and I'm crossing my fingers that it will be used. I'd be curious to see what they have to say. Does your house use this?
