Web sites for the heavily advertised EdenPURE quartz infrared portable heaters such as:
Now, the Copper Development Association Inc., CDA, is the market development, engineering and information services arm of the copper industry, chartered to enhance and expand markets for copper and its alloys in North America:
Earlier this year the CDA was asked about cured copper. The question and their response follow.
Question: I just read an ad for a space heater which contained the following: 'Cured copper is a type of copper that goes through an extensive heating process to give it special properties'. Do you have any idea what they mean?
Response: They mean that cured copper has the property of storing large amounts of heat. In our opinion, it is not possible to do that to copper. (Tony Rakich)
Also, in October 2007 Consumer Reports magazine tested sixteen electric portable space heaters, most of which draw 1500 watts. Go to your friendly local public library and read their report on pages 32 and 33. The 1500-watt EdenPURE Quartz Infrared 1000 tied for last place (15 or 16 out of 16). So their "amazing heating element" hardly delivers amazing results in comparative tests.
