Radiation is a term used to describe transfer of heat energy from one medium to another that can take place even in vacuum. In other words, radiation does not require a third medium to travel. Radiators were built initially to cool down a system of fluids by taking their heat and emitting it to the environment. The concept was used in exact opposite sense to provide heat to buildings in cold regions. Radiators pass a heat source, usually water, which radiates heat to surrounding air. Air when heated rises up and is replaced by new air pocket and the process continues, eventually warming the entire room. This is also called as heating by convection.Plumbers Crystal Palace is a must place for you to visit before you make an informed decision about where and how to replace your old radiator.We would also like you to know the following about radiators if you are planning a replacement:Its heavy.Radiators can be pretty heavy especially if the pipes are made of solid steel. There are radiators which use modern technology materials like fibre that can withstand the high temperatures and are also lightweight.Its dangerous.Radiators can produce a lot of heat and usually regulated, but in case the regulator fails, the generated heat can be high enough to pass ignition temperature of highly inflammable materials.Its costlyRadiators use a lot of electricity to produce the kind of heat that is required to heat a room or an entire building. They incur a huge expenditure for the user over a long period.Its technologically oriented.Radiators come in different varieties such as steam radiators which use steam as the radiating source or hot water radiators that use heated water as their radiation source. These two differ vastly in their design and thus technology.You will need to keep all the above mentioned points when buying a new one.But do not worry because Plumber Crystal Palace takes care of your safety, comfort and budget and strives to provide you the best products.
