An oscillating fan rotates from side to side while blowing cold air out. Because of this movement, it is more effective than a stationary fan. While a stationary fan can only push air straight ahead, an oscillating fan sends air in multiple directions, creating better air flow.Know More
Oscillating fans are driven by a magnet and an electric motor inside the stand itself. When electricity flows into the coils surrounding the fan's inner rotor where the magnet is housed, a magnetic field is created. The central rotor is pushed partway in a circle away from the magnetic repulsion, but then electricity flows into another coil on the opposite side, and the rotor is again pushed in another direction, sending the fan back across its path until the cycle is completed and then repeated.
In some fans, the oscillation isn't from side to side but rather up and down. The basic mechanical process remains the same, only the direction the rotor moves in is altered. Most oscillating fans are best placed strategically in a corner of a room, as from this position they can spread the air out across the greatest area. That being said, many oscillating fans also feature a switch or knob that can lock them in place to focus the air straight ahead in one direction as well, mimicking the style of a conventional fan.Learn more about Heating & Cooling
The easiest way to tell if the fireplace flue is open is by placing a hand into a cooled fireplace and feeling for cold air. If there is a burst of cold air, the flue is open. Ceiling-to-floor metal fireplaces have a metal latch located on either side of the fireplace that allows for easy testing of the flue.Full Answer >
The Family Handyman recommends that owners check their thermostat before assuming the problem causing the furnace to blow cold air is something deeper. There are several things to check at the thermostat. The switch needs to be on heat and not cool. If the fan is set to automatic it blows air, regardless of the room temperature. If the thermostat is set too cool, the furnace does not provide heat.Full Answer >
The most common signs of a bad or malfunctioning thermostat are lack of hot or cold air when the device is turned on and an unlit display light. Malfunctioning thermostats occur for a variety of reasons, and in many cases, troubleshooting the issue and following up with a simple fix can alleviate the problem.Full Answer >
An enclosed ceiling fan is a fan with completely or partially enclosed blades. These fans, also referred to as caged fans, can be used in commercial, industrial and residential settings. Cages, commonly referred to as grills or nets, are made from metal, wood or plastic.Full Answer >
