USA radiators
The advantages of cast iron and aluminum radiators
Gone are the days when the radiators were exclusively iron. Today, manufacturers of radiators offer a wide range of products made from different materials - iron, steel, aluminum and bimetal radiators. Each material has its advantages and disadvantages.
The main advantage of cast iron radiators - their incredible durability and resistance to corrosion. The service life of cast-iron radiators is 50 years old! At the same radiators of this material is not demanding as a coolant for a long time keep warm. If, however, cast iron radiators increased cross-section of water channels, then wear it, as they say, will not.
However, cast iron, as a structural material, has its drawbacks. Among them - not very high heat transfer and a large internal volume. In addition, the iron particles can contaminate the heating system. Given the pros and cons, cast-iron radiators are widely used in the construction of buildings of varying height. Production of cast iron radiators is less expensive, which makes cast iron radiators available for most buyers. And their appearance is much more attractive than in Soviet times. Among the models of cast-iron radiators manufacturers offer products, stylized antique, as well as heating radiators with modern design.
Unlike the cast-iron radiators, aluminum radiators have a high emissivity and low weight. Among the advantages of aluminum radiator manufacturers also produce an attractive and modern look of the material. Aluminum radiators are more expensive than iron, and thus more demanding as a coolant. Therefore, when purchasing aluminum radiator is essential to specify how they are adapted to USA conditions.
However, manufacturers of radiators have found a solution for low-quality coolant. This - bimetal radiators. In the production of radiators of this type of aluminum are inserted water channels from the steel pipe. Therefore, bimetal radiators combine the reliability and advantages of aluminum radiators. Lifetime bimetallic radiators higher than aluminum. In this case, they are less demanding as a coolant, rather than aluminum radiators.
Most aluminum radiators are used in low-rise building, in private homes and cottages.
When buying a radiator, except for technical data, to draw attention to the manufacturer radiator. On the market today are many European and USA companies engaged in production of radiators. The advantages of European manufacturers - modern design and high quality materials. However, manufactured in Europe radiators are often not adapted to Chicagon conditions. Therefore, the reliability to take USA radiators, most of which takes into account the quality of the domestic carrier. Moreover, among USA firms have manufacturers producing radiators, not inferior in design and quality of European counterparts.

Amtrol expansion tanks for heating systems
They are used in modern energy-saving heating systems closed. What these systems differ from traditional described in the article "The Evolution of heating systems"
Amtrol Expansion tanks are steel housing with built-in membrane of artificial rubber and are designed to compensate for the expansion of the liquid circulating within the heating system.
Amtrol expansion tanks for heating differ:
*on the maximum allowable working pressure, ie wall thickness of the tank (depending on the operating pressure used type of heating system)
*the type of mounting flange to the tank - removable or fixed membrane (for tanks with small capacity are usually rolled manner of attaching the flange to the tanks of large capacity flange screw, which allows the replacement of membranes)
*the type of rubber - for systems operating on water use heat-resistant rubber SBR, for the systems to use antifreeze membrane of rubber Nitril
*in capacity, which should be specially calculated for each specific system, depending on its internal capacity and power boiler
The design, selection and calculation of the expansion tank for heating
