My daily paper once again ran a full-page ad for the EdenPURE Quartz
Infrared Portable Heater. The explanation for how this marvelous gizmo
allegedly works is pure Star Wars (movie) hocus-pocus.
It supposedly involves the use of "cured copper" which is "a type of
copper that goes through an extensive heating process to give it
Can anyone tell me how you cure copper? Do you just smoke it like a
fish, or do you first need to marinate it in brine (perhaps with
Here is how they claim their heater works. See:
"Electricity ignites the powerful quartz infrared lamp...The quartz
infrared lamp gently warms the patented cured copper tubes without
combustion... Heat from the copper tubes rides the humidity in the room,
providing moist, soft heat without reducing oxygen or humidity."
We do not believe what we write, and neither should you. Information
furnished to you is for topical (external) use only. This information
may not be worth any more than either a groundhog turd, or what you
paid for it (nothing). The author may not even have been either sane
or sober when he wrote it down. Do not worry, be happy.
"Cured copper is a type of copper that goes through an extensive heating
process to give it special properties"
So yes it's obiously heated in a special manner which may include burning
old oak trees.
( I always thought that was called Annealing or hardening ?)
If it is ignited then it's burning isn't it?
However i believe Quratz can't burn, it starts to melt at 1683C
11. What are the Pros & Cons of CDM vs. Quartz? This is perhaps one of our
most commonly asked questions. Ceramic Metal Halide, better known as CDM or
CMH is a high output, low wattage lamp source which utilizes an electronic
ballast. Depending on the type of unit in question a 150-watt CDM product
may equal or exceed the output of 750-1000 watt quartz unit. Lower wattage
high light output is the key to CDM. Due to a high color rendering (CRI) of
85+, CDM products make fantastic themed architectural products. In addition,
the CDM product has a lamp life of 6,000-12,000 hours where Quartz has
between 300-4000 hours. Though quartz lamps may use more energy and burn
hotter, they do have some key advantages. Quartz has the ability to dim from
0-100%; CDM does not. Quartz products do not require the use of a ballast
therefore they tend to be almost half the price of their CDM counterparts.
Although lamp life is shorter, the replacement lamp cost is also less. We at
Altman are pleased to be able to offer both CDM and quartz options, along
with a Quartz to CDM retrofit kit.
The bumph on there site is a laugh, basically most of it is comparing
gas/combustin burners with electric ones, as it's not gas it isn't burning,
not not using up oxygen etc.
Basically whatthis is is Qaurtz lamps inside copper tubes to spread the
heat, put in an oversized box so it isn't likely to get to hot on the
The have a very interesting concept of something that does not get hot yet
gives out heat !!
Ok first they say "Does not get hot" Then they say "It does not get hot
enough to ignite anything"
There must be plenty of substances that don't require a high temperature to
Anyway it's old hat, there are more effecient heaters than that.
However it reminds me of a comment made to me by a workmate last week.
He asked me if i'd heard of the new LCD Televison screens.
He'd been shopping somewhere and read some bumph which went as follows:
"Our LCD panels are unique and offer a much better picture than other
manufacturers, this is because our screens combine LCD technolodgy with TFT
He had seen these and was convinced it was special, so convinced he'd buy
it, i can only think that the shop deliberatly altered the pictures on the
others to make this one look good as LCD panels have used TFT for years, no
one makes anything else because there is no better yet.
It's the same ploy used by car manufacturers to sell cars, instead of saying
1600occ they say 16 valve, yet 16 valve engines were around a long time
before someone had the bright idea of pointing it out as a sales gimmick.
Likewise CPU manufacterers invented a new way of stating proccessor speed,
higher numbers sound better !
Yes, it is an old story. What is new is that in October 2007 Consumer
Reports magazine tested the EdenPure Quartz Infrared 1000 along with
fifteen other electric space heaters. The EdenPure tied for worst
performance in their ratings. So, it probably needed a redesign.
After rereading the Edenpure ad, I conclude that the medium used to
heat the copper is more likely horse manure (spewed by the marketing
department) than burning old oak trees as you suggest.
