Comfort Spot Heaters for Commercial, Residential and Industrial Applications Spot heating locates the heater above the areas you are located so the air in the entire room is not heated. Infrared heats objects not air, so you are kept warmer even in a relatively cold room.
Some heaters use a quartz glass heating element and some use a metal sheath tubular element.
Metal heaters last longer, do not emit light, and are not as subject to damage from environmental factors, shock and impact. Most types of infrared heaters can be used outdoors, providing it is entirely shielded from rain and wind driven rain. Typically quartz lamp heaters are used because they reach higher temperatures and they are less susceptible to heat loss from wind because of less mass to hold heat which can be lost to a rise in temperature of the air crossing it.
