Radiant heaters use a variety of heating elements. Many use quartz tubes. Quartz heaters generally cost less than $70 and are rated between 750 and 1500 watts.
Parabolic heaters use a ceramic core. They cost a little more than quartz and put out about the same amount of heat per watt used. Ceramic element heaters are safer than heaters with coils. They use a larger heating area so it doesn't need to be as hot.
Halogen or reflective heaters use an energy saving halogen bulb to produce heat which is reflected on nearby objects. The feeling is much like having the sun shine on you.
Convection heaters can heat a whole room more quickly than a radiant heater. That works well if there are a number of people in the room or they're moving about within the room. Some convection heaters also have fans to circulate the air in the room. Convection heaters are inexpensive. You'll get one rated up to 5,000 Btu's for less than $50.
Like radiant heaters, convection heaters use a variety of heating elements. Ceramic disc heaters cost up to $150 and produce up to 5,000 Btu's per hour.
Oil and water filled units are the most efficient convection heaters. They utilize a heating element in a bath of oil or water. Like a water heater, the element cycles on and off. The water or oil stays warm in it's container and heats the surrounding air.
