[quote=Anonymous]When we gutted and reno'd our bathrooms, my lazy contractor insisted he didn't have to vent to the outside--because my attic has ample cross-ventilation, he swore that sending fan exhaust into the attic was enough. I insisted that he use a flexible duct to exhaust the fans horizontally to a soffit vent, based on this intuition: venting vertically through the roof (which would have been shorter and easier) would result in heat loss from heat just naturally rising out of the vent, constantly, even when the fan was off. With a horizontal duct, there's not a natural chimney-type flow--the heat rises to flat duct, and stops (or seeps much more slowly), so it's only really sucking out heat when the fan is turned on. Fan might work harder, but it's not a constant heat suck. Now, this is based on nothing but my intuition. Someone who knows about this tell me: am I right or am I wrong? [/quote]
