Contents.Operation Space heaters are powered by electricity or the combustion of flammable fuel. Space heaters burn flammable fuel, such as natural gas, kerosene, propane, or wood.Electric space heaters fall into three main categories:. pass electricity through a, causing the element to become hot. The elements are either metal or, and the process is known as. Heat is transferred to the air in the room.
Some heaters have a to increase air circulation, but do not have fans. also pass electricity through a conductive wire, heating it. Most of the heat is, rather than convection. The hot wire emits rays, which transfer heat to a solid surface rather than the surrounding air. use the same process as and, but in reverse.
While convective and infrared heaters make heat from electricity, heat pumps move the location of heat. Heat pumps move heat from outside a room to inside, warming it. Many are reversible, able to cool the room by pumping heat out.Convective heaters Many residential space heaters use convective heating.
They can be divided into two categories: those with a fan (to distribute warmth), and those without a fan. Convective heaters provide constant, diffuse heat to well-insulated rooms.With a fan. Goldair ceramic heaterSome convective heaters use a fan to help circulate warm air throughout a room. Their heating elements are metal or ceramic and are in direct contact with room air, allowing to warm a room quickly.Without a fan In convective heaters without a fan, the heating element is surrounded by oil or water. These heaters warm a room more slowly, because the liquid must be heated before the heat can reach the surrounding air. They produce more heat after being turned off, however, because of the hot liquid inside the heater.

The risk of fire (and burns) is sometimes less with oil-filled heaters than those with fans, but some fan-assisted heaters have a lower risk of fire (and burns) than other oil-filled heaters. Radiant heaters. See also: andThe main advantage of radiant heaters is that the infrared radiation they produce is absorbed directly by clothing and skin, without first heating the air in a space. This makes them suitable for warming people in poorly insulated rooms or outdoors, and allows more distance between people and the heater.Some of the earliest electric heaters were radiant, consisting of heating wires held by or insulation at the of a (usually) polished metal.
The cost was very low since nothing else, not even a switch, was needed. Later models included a wire guard to prevent accidental contact with the heating wires or the hot ceramic.The metal reflectors needed to be fairly thick, however; a thin metal housing would get too hot to be safe. Inexpensive mid-20th century heaters were radiant, with the heating wires stretched relatively closely across a larger, thin, metal reflector separated from a thin metal housing.
A small fan blew just enough air between the housing and the reflector to cool them, and the main output to the room was radiant heat (not heated air). Stretching the heating wires across a larger area required fewer (expensive) ceramic insulators, and a small fan was cheaper than a larger (or heavier) housing.Quartz heaters are radiant heaters which are more efficient in the amount and direction of heat, with coiled heating wire inside unsealed tubing.
The wires could be thinner (or operate at a higher temperature) than ceramic-supported wires. If the heating elements are at a higher temperature, proportionally more energy is radiated than open-wire heaters.Halogen heaters have filaments in sealed quartz envelopes, mounted in front of a metal reflector in a plastic case.
They operate at a higher temperature than nichrome-wire heaters but not as high as incandescent light bulbs, radiating primarily in the infrared spectrum. They convert up to 86 percent of their input power to radiant energy, losing the remainder to conductive and convective heat. The reduces darkening of the quartz envelope, extending filament life.Power sources Many space heaters (including oil-filled radiators and natural stone heaters) are plugged into an electric power source, most commonly a two-prong – for older models – or three-prong outlet.
Appliance power is measured in kilo (kW), which permits simple estimation of operating cost per hour (since electricity is billed in, or kWh).Safety Fire, burns, and are the main risks of space heaters. About 25,000 fires are caused by space heaters in the United States each year, resulting in about 300 deaths. Roughly 6,000 hospital visits annually in the US are caused by space heaters, mainly from burns. Operation Improper use can increase the risk of fire and burns.
Safe operation includes:. Plugging space heaters directly into a wall outlet or heavy-duty (14- wire or larger) extension cord. Light-duty extension cords can overheat and cause fires. Plugs and cords should be checked periodically for cracks or damage, and replaced if needed. Flammable materials, such as curtains, furniture, and bedding, should be kept at least 3 feet (0.91 m) from the heater. Turn off the heater when the last adult leaves the room or goes to sleep. Children and pets should be kept three feet from the heater.
Heaters should be placed on a flat, hard, nonflammable surface. Avoid using heaters near flammable materials such as paint or gasoline. Smoke alarms and should be installed nearby.Features No one type of heater is safer than any other type. The risk of fire and burns can vary, depending on model and manufacturer. However, lower surface temperatures generally reduce the risk of fire and burns. Safety features have been added to some space heaters.
Safety switches will shut off the heater if a dangerous situation is detected:. Tip-over sensors detect if the device is no longer upright (often found in the bases of halogen heaters). Thermal shut-off switches detect if the heating element becomes too hot. Spectrasonics omnisphere keygen torrent.
Airflow sensors detect if an object is blocking the heater exhaust.Certifications In the United States, ' UL 1278 (for portable electric space heaters) and UL 1042 standards (for portable and fixed baseboard electric heaters) certify heater safety. Although the had Specification W-H-193for electric space heaters, it was replaced in 1995 by the UL standards. Additional information on portable-heater safety may be found at the Energy Efficiency website. Efficiency The has evaluated a number of space heaters, but none have received its label.
