You can reduce your utility bill by extending your dryer vent high into the attic while saving energy and money.
Extending your dryer vent into the attic can reduce your utility bill.
One issue I have yet to see addressed in an energy conservation article concerns the air supply used for common household clothes dryers. You can reduce your utility bill by constructing a simple duct that runs from the air intake on the rear of the dryer to a high point inside the attic near the ridge, where the hottest air is on sunny days. This attic-intake system saves in two important ways: First, no conditioned air is taken out of the house; and second, the hot air used from the attic reduces the amount of electricity the dryer requires to create heat. The duct system consists of a 6-inch diameter sheet metal pipe fitted into a fiberglass insulation sleeve made for round ducts. I hope this information will be useful to others looking to reduce utility costs.
