Quartz Heater Efficiency
What makes quartz heaters so efficient is that they use a wound resistance coil that runs through a series of parallel tubes. All of the parts are encased in highly reflective, aluminum steel body, which prevents heat from escaping to the back of the devise.
Ceramic Heater Efficiency
Ceramic heaters are robust and efficient heaters and are responsible for providing a long wave infrared radiation. These types of heaters use a specialized process, which involves an alloy resistance wire that is wrapped around a ceramic body.
Quartz heaters convert 100 percent of the electrical energy it uses into heat, but lose their efficiency after 10-15 feet. Quartz heaters are made for situations where you are sitting in one particular place and only need to heat the one area. Properly designed ceramic heaters offer 85 percent efficiency and are able to heat up an entire room. Ceramic heaters offer flexibility in zoning, long life and uniformity.
You need to be careful when using quartz heaters, and they shouldn't be situated closely to a solid object. If the heat becomes too concentrated or focused on a small area, it can result in burns or even cause a fire. Ceramic heaters tend to be more safety efficient, because they operate at a lower temperature.
The ratio of convected heat to radiated heat is higher in ceramic heaters; therefore, quartz heaters are a popular choice for overhead heaters. Quartz heaters can move up to full working temperature more quickly, because they don't have the mass of a ceramic heater.
