Why Do Chrome Radiators Have a Lower Heat Output?

Currently, radiators are available in a wide range of models
that include modern, designer and traditional styles, each of which has its
range of finishes, from white to low profile oranges and bright chrome. Buyers
need not only comfort but also an elegant product to add to their interior
decoration, so heat production, as well as design and decoration are crucial
when choosing a heating product.
However, when it comes to thermal outputs, customers may
find everything quite confusing. One reason is that heat production may vary
only depending on the finish.
For example, a contemporary design style can be white, black
or chrome. You might think that with the same size, everyone will give the same
heat output, but this is not so. In contrast, black and white models produce
20% more heat than the chrome version. Chrome versions always generate less heat
(up to 30% less) than the painted equivalent.
So why do chromed radiators give off less heat than painted
radiators?
There are 3 main reasons why chrome models cannot emit so
much heat:
1. Firstly, this is due to a scientific phenomenon known as
“surface emissivity”. Chromium has a low emissivity; This means that chrome
tends to trap heat and is difficult to give off or radiate heat.
This explains why your car’s seat belt buckle is so hot on a
sunny day. Although this does not make them ideal for “radiators,” chrome
provides excellent material for drying towels.
2. Chrome is a coating applied to another metal, usually
mild steel or brass. This means that heat must penetrate through 2 layers of
metal;
3. Inside, chrome is as bright as outside, which means that
it reflects heat itself, reducing the amount that it can radiate; It affects
similar to the space blankets that you see, wrapping athletes over long
distances after the race.
10 years ago, chrome or chrome finish was the most popular
finish, but they are increasingly moving away from chrome due to reduced heat.
Now, customers often choose polished stainless steel, since this alternative is
very similar in appearance to chrome, but since it is not bare metal, but a
coating, it is better to “radiate” heat.
There is also some difference in the emissivity of not only
the finish but also the colors. Nevertheless, the industry agreed that in
practice this difference is not significant and that the production of
advertising heat for each tone can significantly complicate the consumer’s
decision. Besides, manufacturers will need highly accurate, sophisticated and,
therefore, expensive measuring instruments to quantify the difference by adding
unnecessary costs. Therefore, models with white trim and other “painted” or
powder-coated coatings are always advertised the same way.
Keep in mind that retailers may also advertise the same
products with the same finish with different heat output due to differences in
measurement standards used in the UK and Europe. For more information about
changes in heat output, see our article “Different companies sometimes install
different heat capacities for the same radiators, why?”

Feature radiators are widely recognized as one of the
leading heating retailers in the UK, and David Banyo, a Chrome
radiators fan, wants consumers to receive unbiased heating information:
“I would like to make sure our customers are as knowledgeable as possible so I
use ezine to convey interesting and informative information to help them always
get the best product that meets their specifications. ”
