Heating Radiators.

A heating radiator is one of the main elements of a water heating system.

The name of the radiators is derived from the word "radiation" (heat radiation process). The coolant (water or antifreeze) contacts the internal walls of the radiator and transfers heat to the air in the room. Radiators or, as it is often called, batteries can be conditionally classified into:

• Tubular radiators (as an example, water towel rails or design radiators)
• Sectional aluminum and bimetallic heating batteries, which consist of several sections)
• Panel steel batteries.

By its purpose, the batteries can be divided into two main groups:

• For autonomous heating systems (country houses, cottages, freestanding buildings)
• Universal, suitable for any, both stand-alone and central heating systems (buildings of any type, including multi-family houses).

Steel radiators are manufactured in the form of stamped steel panels.

The main advantages of such batteries:

-small inertia

-relative simplicity of product design

Steel batteries in the opinion of experts are better to install in autonomous heating systems. They are manufactured in a wide range with different dimensions, thermal characteristics and types of connection.

Cast-iron radiators are the most popular in Russia.

The main advantages of such batteries are that they are not subject to corrosion, are very durable and have a long service life.

From the point of view of modern heat engineering they have one very big minus - a large volume of water and, as a consequence, a large thermal inertia.

Aluminum batteries are light, have high heat dissipation. In addition, they have a very nice appearance and attractive price. In the rating of selling in Russia, they occupy an honorable second place. One and minuses of such radiators are relatively short lifespan, this is due to the fact that aluminum is an active metal and has the property of oxidizing.

Bimetallic sectional heating radiators are an improved type of aluminum batteries (the design consists of steel pipes filled with aluminum alloy under pressure). In fact, we can say that bimetal radiators are the same aluminum, only with a longer service life and operating at higher pressures of the central heating system.

To seriously approach the purchase process and choose a specific battery, you must first calculate its required heat output. Usually it takes 1 kW per 10 square meters of heated area, but this range can vary with an increase in the ceiling height of more than 3 meters, as well as the specifics of the region and the structure of the room. Then it is necessary to determine the dimensions of the instruments, since there should be enough space around the battery for air circulation.

Before buying a radiator it is better to consult with specialists.
