When thinking about a central heating system, one needs to consider its various components and how each one works to provide the heat. And next to the boiler, perhaps the most important component of this system is the radiator. Central heating radiators warm up due to the hot water from the boiler and then radiate the heat into the room. It does this by letting the water pass through hollow tubes, which are bent back and forth about 10-20 times to maximize the surface area by which the water’s heat can radiate outwards.
These radiators can be made of two materials: aluminium and steel. Aluminium radiators are cheaper than steel, and are also highly efficient and effective in handling high temperatures and pressures. Another side benefit is that aluminium is light, and can be easily installed. However, this metal typically lasts only about 20 years. The seals between aluminium parts are also prone to rupture, which may increase maintenance costs. On the other hand, steel is better than aluminium in handling higher temperatures, and may have less maintenance costs. However, they still need to be maintained regularly for proper operation.
The radiators can also be found in several designs. These are intentionally made to suit various house interiors. As such they are available in rectangular, hoop, curved, or columnar shapes. They can also be mounted horizontally and vertically. And needless to say, they also come in various colours. But for those who are less particular about design however, the columnar shape is an excellent choice, for this configuration promotes a more even heat distribution.
Knowing these things, one may be tempted to immediately scout around for a good radiator model. One should keep in mind though, that an expert’s opinion on the matter should also be sought. For instance, the calorific value, or the amount of heat that the system can put out, should be determined precisely by a professional. That way, there will be no disappointment on the adequacy of heat.
