In recent years the popularity of Cast Iron Radiators has experienced a tremendous increase with an ever-growing number of

home owners seeking to purchase such heaters, favouring them over other types of radiators such as electric convector heaters.

There are several reasons as to why this is the case. Firstly, it is speculated that the

increasingly popular fashion of ‘vintage’ and antique items (or items which at least appear

to be vintage).

However, another reason why a lot of people choose to purchase Cast Iron radiators is due

to their reputation of being far more economical to run than many other forms of heater, due to their ability to keep producing

heat even when they are switched off, possibly resulting in the home owner

experiencing considerable savings on energy costs. It may also be solely due to the fact

that Cast Iron Radiators are very easy on the eye and therefore appeal to a large number of

home owners.

Despite the many reasons for one seeking to buy Cast Iron Radiators, it is highly unlikely that the majority of people who purchase them actually

know How Cast Iron Radiators Work.

There are different operating systems for different styles of Cast Iron Radiators depending on whether they operate in steam or hydronic systems. In a one cylinder system, the steam enters the radiator and

is then pushed out of the heater through an air valve on the other side of it.

However, once the air has escaped the steam then hits the air valve before closing it, allowing the radiator then to pressurize. On the other hand,

once the radiator begins to cool down, the steam is then condensed back into water, thereby enabling the air valve to open up again and allows the water

to travel back down to the boiler, allowing it to then be reheated.

In a hot water system, on the other hand, the radiator is permanently filled with water. As the

system is then heated up, the hot water circulates throughout the radiator and heats up.

The particular characteristics of Cast Iron also play a large part in the operation of Cast

Iron Radiators. For example, the ability of this particular alloy of iron to conduct heat exceptionally well (making it a very suitable substance in the creation of radiators) but it is also difficult to corrode, meaning that it is very suitable for a purpose involving a large amount of water (in the form of steam and

liquid) passing over it.
