Both types are beneficial depending on the space you are trying to heat. There are also different subtypes of each type.
Radiant Heat: Radiant heaters have heating elements which give off infrared radiation. This type of heat will warm the people and objects in a space, but it will not heat the air. This type of portable electric heater is ideal for small areas. There are two types of portable electric radiant heaters: metal-rod radiant heaters and Quartz heaters.
Metal-Rod Radiant Portable Electric Heaters: These portable electric heaters are great on-demand heaters because they heat up quickly. They have a heating element strategically placed in front of a reflector, which radiates the heat outward. The down-side of these is they give off very high direct heat, which can be a fire hazard. It is important to never leave these portable electric heaters un-attending and never place them near loose fabric, such as curtains or bed spreads.
Quartx Portable Electric Heaters: This particular type of heater contains heating elements within a quartz glass tube. These portable electric heaters can be extremely dangerous because the glass tube breaks easily, which can start a fire. Don�t use these heaters anywhere they could potentially get knocked over.
Convective Heat: convective heaters circulate hot air around a room. Due to the fact they heat the air in the room, they are better suited for larger rooms. These particular portable electric heaters come in three different styles: electric-element, liquid-filled or ceramic.
Electric-Element Portable Electric Heaters: These portable electric heaters are attractive because they are inexpensive and easy to use. They work by moving air past a heated coil. The coil warms the air and keeps it moving. It works quickly and heats the air in the room. If you buy one with a programmable responsive thermostat, they can be used to maintain room temperature.
Liquid-Filled Portable Electric Heaters: These work by heating water or oil with a heating element. The hot liquid is then used to heat the air that passes through the heater. Although liquid-filled portable electric heaters can maintain the heat in a room better, they take much longer to start working, which does not make them good for on-demand heating.
Ceramic Portable Electric Heaters: These heaters are very light and compact. They contain a ceramic heating element, which draws in air and then heats it before releasing it back into the room. These heaters can not be used to maintain a certain room temperature. On the good side, the ceramic element can not get hot enough to start a fire so they pose less of a risk as other portable electric heaters.
When purchasing a portable electric heater, there are a few things you should look for. Make sure the heater has an automatic shut-off if it is tipped over. It should also have an automatic shut-off if the unit gets to hot. These are the two main causes of fires caused by space heaters. If you have young children or animals, make sure the heating element is securely enclosed.
