Space Heater Identification
A space heater is a heating unit that produces warmth for a small area as opposed to central heating systems, which cycle warmth throughout an entire structure. Space heaters are typically electric; they are plugged into wall outlets or run on batteries. They come in two main types: convection heaters and radiant heaters. Convection heaters produce heat for an entire area whereas radiant heaters direct the warmth from the heater in a specific direction.
Ceramic Heaters
Ceramic heaters are typically electric heaters but sometimes can use other types of fuel (such as propane) to produce heat. Unlike other electric heaters, a ceramic heater reflects the energy produced by the electricity or fuel between many different reflectors within the device, heating ceramic plates that produce heat, which is blown through a fan into a room. Because of their construction, ceramic heaters are more energy efficient than other electric heaters, cutting down on electric bills.
Electric Heaters
Electric heaters use electricity to heat up metal coils within the machine, which then give off warmth. Some also use quartz rods to produce the same effect. Electric heaters are generally less efficient and thus more expensive than operating ceramic heaters. They can also carry some hazards. Metal coil electric heaters can grow very hot to the touch and even start fires. Ceramic heaters, on the other hand, are generally cooler to the touch during operation.
Costs
Electric heaters come in a variety of types, and the cost of a space heating unit depends on which type of heater you are buying. Ceramic heaters can cost anywhere from $30 to $60, as of June 2011, while convection heaters can cost anywhere from $15 to $100. Radiant electric heaters run anywhere from $30 to $100. Cost largely depends on the model you buy and the manufacturer. Purchasing a well-made electric heater is essential; shoddily-made heaters can pose increased safety risks.
