When transferring your clothes from the washer to the dryer, be sure to shake them out so they're not all wadded up - fluffed up clothes dry faster.
We purchased a thingamajobber called a "Heat Saver" at Menards (like Lowe's, Home Depot, etc.) that you install in the vent line. It has a flap that you can open or close seasonally, so in the winter, you can blow the warm, moist air into the house instead of outside. We make the electricity for the dryer do double duty - dry clothes and heat and humidify the house. NOTE: It is only recommended for electric dryers, because of possible exhaust fumes from gas dryers. In the summer, you flip the flap and it vents outside, but we don't use the dryer spring-fall - everything goes out on the line. The Heat Saver cost about $5. We haven't had to turn on the humidifier yet this winter, and the gas company says we're using HALF of the propane the previous owners did. (Our first winter in this house. The fairly mild winter and keeping extra rooms closed off with thermostat set to 62 day, 57 night might have something to do with that, too...

Sophie9910, isn't that great? And your clothes don't come out over-perfumed, either. I found that you can use 1/3 sheet per load and it works too. But 1/4 sheet doesn't get the job done. (Discovered by playing the "how low can you go" game.
