WEST LAFAYETTE, Ind. (AP): Hoosiers trying to cope with the propane shortage may find helpful hints on a new Purdue Extension website. The site contains tips to help users conserve propane gas and use it more efficiently in heating their homes. Among the tips are placing rugs on bare floors, humidifying the air, turning down or shutting off the heat in unused rooms, and reducing the use of kitchen fans, bathroom fans and other ventilating fans, which pull air out of rooms. Leaving a fan on too long will result in more fuel being used to heat the home.
