Can Space Heaters Be Hazardous?
Normally during the winter season fuel prices tend to rise and most residents in Atlanta, GA will be making use of space heaters to kill the chill. According to a report published by US Consumer Product Safety Commission (USCPSC), more than 25,000 residential fires are caused by these heaters, which also cause about 300 deaths. More than 6000 patients are admitted to hospital emergency rooms for injuries caused due to contact with the heated surface of these heaters.
Since space heaters carry a much higher risk of fire than a central heating unit, people who are planning to use these during the winter months should be extra careful. These heaters have proven to be hazardous, mostly due to human errors like placing them too close to combustible substances, leaving them on without the supervision of an adult and improper maintenance.
Electric space heaters are mainly used to warm up small spaces. These heating devices are preferred by Atlanta residents who cannot afford the cost of running their centralized heating unit and rather heat just a single room and not the entire dwelling unit. Also, these heaters are found in the work place under a desk to heat the feet of an employee that isn't getting the full effect of the central heating unit.
Space heaters can help Atlanta residents get some much needed warmth, but these devices should not be left on for the entire night, or unattended because of the following reasons:
Safety concerns: The Consumer Product Safety Commission (CPSC) suggests that these heaters should only be operated when an individual is available to monitor the status of the device. Today, electric space heaters are being used to produce just enough heat for the surrounding areas in a matter of minutes. The CPSC suggests that using these heaters in bathrooms and kitchens could also prove to be dangerous. Electric space heaters should not be placed near water sources. Cause Fire hazards: A report by the National Fire Protection Association (NFPA) suggests that these heaters should not be operated without a person being present to supervise it. This is because the heaters that were left running overnight causes 54,900 fires in 2008 that lead to 220 deaths. The risk of fire is greater with kerosene space heaters, which are now banned in some states. Health risks: Fuel operated space heaters also emit carbon monoxide, which can cause various breathing disorders.
To protect yourself from the dangers of space heaters, never operate them when you are sleeping. Also seek the services of an electrical contractor to install a smoke detector in the room where these devices are being used.

Is an Electric Heater Right for You?
Most heaters are usually powered by either electricity or fuel, and while both types of heaters have their own individual benefits, electric heaters seem to be the most popular option because they are often inexpensive to purchase and easy to maintain. They primarily work by converting electricity into heat via an electric resistor within the heater, and an electric current flowing through the resistor then coverts the electric energy into heat energy.
Some of the benefits of an electric heater are obvious - electricity is available anywhere, and they do not require any fuel to be stored.
It is also important to understand safety issues when purchasing a heater. New models of electric heaters are required to pass rigid safety tests in order to ensure safe operation. Wire grills, tilt switches, automatic shutoff controls, and thermostat controls are all safety features to look for.
Although all electric heaters use the same basic principle to generate heat, there are variations in how they provide this heat to the environment. Here are some different electric heating methods available:
Convection Heaters:
These types are great for providing background warmth for a closed space. Convection heaters warm the air near the element or body of the heater by using air convection currents to generate heat, and these currents circulate throughout the appliance and across its heating element. Examples of convection heaters are oil-filled radiators, which are perfect for personal spaces such as under desks and electric baseboard heaters, which are great for heating rooms such as a bedroom or lounge area.
Infrared Heaters:
Infrared heaters transfer thermal energy via electromagnetic waves, and all infrared heaters share one common characteristic: heat is emitted or radiated from the heated object or substance, and only objects are warmed (as opposed to entire areas). In general, infrared heaters are energy efficient and great for multi-purpose use, but they are especially effective for industrial use such as warehouses and even greenhouses where high temperatures are required to be quickly reached.
Fan Heaters:
A fan heater is a type of convection heater that uses a fan to pass air over a heating element in order to speed up the airflow. This heating element heats the air, the air leaves the heater, and the surrounding area is warmed. This can result in extremely rapid heating in a room, but these may not be the best choice if sound is a concern, as fan-type heaters can sometimes be noisy. However, fan heaters work well in areas where installing other types of heating devices would be impractical, and examples of fan heaters would be portable fan garage heaters, which are placed on the floor and provide blasts of warm air onto the body.
Of course, fueled heaters such as those using propane or kerosene are also heating choices, but these types of heaters may not suitable for home use because they need to be vented due to carbon monoxide emissions. However, if you are concerned about the cost of electricity and are looking to rapidly heat your patio, warehouse, or other large, well-ventilated area, these can also be considered.
