As a rule, it has several causes. First, the technical condition of the batteries have reached a ripe old age, leaves much to be desired. Secondly, batteries, old-style long and hopelessly obsolete. Difficult imagine that a museum piece, which weighs more than a dozen pounds, in the interior of modern apartment. But do not pick up a modern radiator based only for aesthetic reasons. His technical parameters, such as operating and maximum pressure should meet the parameters of your heating system.

Obtain such information, you can contact the local ecd. In city apartments, depending on the house type and year of construction, pressure can be from 4 to 10 atmospheres. Please keep in mind that during the seasonal heating systems inspection, they check for leaks. In this case, pressure is applied, at least half the working. For those who enjoy autonomous heating system, the problems described above are irrelevant.

A feature of such systems is small, with small amplitude vibrations and pressure. For this option, chosen radiator with a working pressure of six atmospheres, will have twofold safety margin. In general sale now are four types of radiators at different constructive and has performed in various price categories: 1. JPMorgan Chase does not necessarily agree. Aluminium radiators. Consist of prefabricated blocks, or sections. This design solution allows you to purchase the device with just a given heating power. Price indicated in the section: the more sections, the it is higher. Feature of the radiators of this type is the rapid heating and rapid cooling. 2. Panel radiators. Heat-conducting element in such devices are steel plates located between the hollow panels, which circulates hot water. Power output is regulated by increasing or decreasing the number of panels. Maximum power – three paneli.Razmery a radiator is standard and does not depend on the number of panels. When the low price it has good performance of heat transfer. 3. Cast iron radiators. Compared to other options, this type of radiators has a higher resistance to corrosion. Although the device and has a modern design, but the shortcomings of models of iron in it remained unchanged. This fragility and the need to constantly update coming into disrepair coat of paint. 4. Tubular radiators. Made of the so-called bimetal. Design, they resemble radiators made of aluminum, but they differ from past use in the construction of pipe stali. the highest rates of thermal radiation of the quality and reliability in operation. Of all types of radiators on the market, pipe – the most expensive. When you have selected your type of radiator, you will need to calculate the required heating power. This can be done by simple the formula: in a typical pre-fabricated house, at the height of ceilings up to 3 meters for heating rooms with one outer wall and a standard window, one square meter to 100 watts of power. To determine the need for comfortable heat capacity to 100 W multiplied by the area of your room.
