Online Heating Supplies

October 1st, 2009 No comments

Over the last decade or so the world of commerce has changed into something completely different to what it used to be. Gone are the days when you would buy all of your required materials from whoever was your local supplier and this is down to the arrival of the Internet. With online buying and cheap delivery costs, you can buy your desired supplies from whomever you like wherever they happen to be based.

The companies that were quickest to move from a Bricks operation to a Bricks and Clicks operation have been the ones to see the biggest benefit to date. It is easy to feel that many others have been left behind, but the Internet has changed the face of enterprise across the world. There are some household names that as little as 5 or 10 years ago didnt register in our collective consciousness. Companies such as Amazon, Google, Twitter, Facebook, Itunes, ebay etc

Some of these sites will go the same way as sites like Netscape in the future i.e. lose popularity and become redundant. The reason for this is that a new site usually comes along that does the job better. Online competition moves so fast that many organisations get left behind, and keeping up with the pace is a full time occupation for those wanting to secure the top positions in the Google results.

With cheap and reliable courier services available, the size of the product you want to buy is almost irrelevant, if you know where to look, you will be able to find it for a bargain price online.

Online stores will offer the same warranties and returns policies as traditional high street stores, as well as offering considerable savings on top of that. The possibility of receiving a faulty item or of the item being damaged in transit is cancelled out by the saving made at the time of purchase. Many online companies use the price of the item as their main selling point.

Radiators Use Convection, Not Radiation

The appliances found in most households that we commonly refer to as radiators, in my humble opinion, should not be called radiators as they do not technically radiate. In fact, radiators transfer heat using convection.

The term radiation applies to when heat or energy of some kind is emitted outwards in all directions to ultimately be absorbed by whatever body happens to get in its way, this could be a person or anything really.

Convection is the process of heating liquid, which then passes the heat on to the matter around it, in the case of a house hold heater, the water inside a radiator would be heated, then circulated round the (usually white) iron casing, which would then transfer the heat to the surrounding air. There is very little difference in the end results of radiation and convection (at least not in terms of household heating in the short term) but the way the heat is transferred that makes them different.

So despite the fact that the most common household heaters all (or at least mostly) use convection, they are referred to as radiators.

However convection is far less harmful than radiation. This is because convection is simply the air getting warmer whereas radiation is energy travelling in electromagnetic waves which if youre regularly exposed to, can be dangerous.

The two most common types of radiation are alpha and beta radiation. Beta is stronger than alpha but it wont take all that much to block either of them. A sheet of aluminium would take care of both of these radiation types, but if your household heaters were emitting these waves throughout your life, then that could cause some serious health issues such as microscopic damage to your inner tissue, tumours, cancer and possibly damage to the skin.

So all in all, we should really be calling radiators convectors as that is technically how they function, but considering the potential health risks that are presented with radiation, Id personally rather have it the way it is than the other way around!
