Central Heating Radiators Buyers Guide
Central heating radiators are supplied with hot water from a boiler and circulate the heat from that water around your home by processes of radiation and convection. Hot air rises, so as the air close to the surface of a radiator becomes hot, it rises and is replaced by cooler air from beneath and so on. This creates a natural circulation current which distributes heat throughout a room.
Central heating radiators need no longer be anonymous rectangular boxes and there are enough styles, in enough materials, colours and finishes to keep even the most ambitious interior designer satisfied. Cast iron, for example, is an excellent material for radiators; it diffuses heat exceptionally well, yet is strong, durable and long lasting. Stainless steel, likewise, is a strong, non-corroding metal and is often used for towel rails in wet areas, such as kitchens and bathrooms, as well as for radiators. Highly polished or brushed stainless steel finishes are available. Style-wise, convection radiators, including low level skirting board radiators, where air is forced across the heated surface for greater efficiency, can provide an alternative to traditional radiators.
It is worth remembering that the heat output from, say, two separate radiators is always greater than that from one single radiator of equivalent size; in fact, distributing heat output between multiple radiators can also create a more natural temperature gradient in a large room.
