Column -type cast -iron radiators have been heating our apartments for many years. At the same time, their design has not changed.
But why the radiator has such a winding shape? As practice has shown, it is this design that allows you to increase heat transfer. At the same time, it is in contact with the air with a larger area. Hot water enters the radiator under high pressure. Cast -iron radiators ways to withstand pressure in 6 atmospheres and even higher. Such great popularity is associated with their great reliability and strength.
Moreover, cast -iron radiators can be increased in accordance with individual preferences of the owner of the apartment.
But their appearance leaves much to be desired. They do not fit into the modern design of the premises. Therefore, they are hidden using various screens and curtains.
Moreover, they largely lose its high heat -radiant ability. A terrible appearance is a significant drawback of this type of radiators.
Steel radiators are deprived of such a serious drawback. This is a cast product, which consists of the upper and lower collector and the channel connecting them.
The ribs on its surface are used to increase heat -emitting ability. But most of these radiators are not produced in Russia. Causes sincere surprise of the ability of Europeans to create such devices. After all, they do not have such frosts.
But many construction companies I consider steel radiators extremely uneasive.
The height of panel radiators is about 600 mm. Due to this height, they are easily installed under the windowsill. Elegant appearance and maximum stability of color allows you to place them in any room.
Bimetallic radiators are the top of technological perfection. In their production, a special combination of materials is used. Steel core contributes to the strength of the structure, and a special aluminum coating provides high heat transfer. Bimetallic radiators withstand pressure 10 atmospheres. Therefore, they are not afraid of periodically arising pressure drops that occur during hot water supply.
