In 1878, Edison patented the phonograph. One-hundred years later, teen-agers figured out there might also be benefits when records are played backward. Same goes for ceiling fans. They increase comfort and save energy once you learn their heating and cooling depends on which way they turn. All ceiling fans have a "forward" and "reverse" switch. When you click the switch to forward, the blades turn clockwise, and the fan blows air downward. This creates a breeze and a cooling effect. When you set it to reverse, the blades turn counter-clockwise, and the fan pulls air upward toward the ceiling. It's up to you to decide what's best. In winter months, many prefer reverse rotation where room air is pulled upward. This practice causes warm ceiling air to be gently recirculated, cutting down on the running of the furnace. For summer cooling, forward rotation creates a refreshing breeze that saves on air conditioning. What's best for you? Like kids with Edison's phonograph records -- experiment. And that's the On The House tip for today.
