What kind radiators can be found in new and secondary housing economy and business class? Says Roman Šidlauskas - development director of the Russian representative office of the Italian manufacturer of radiators Global Radiatori.
New
In recent years, buyers of apartments in new buildings Economy segment together with concrete walls prepared steel panel or aluminum battery Russian or Chinese origin.
The main advantage of the first - water resistance with high acidity. Where most other radiators start to corrode quickly, steel battery can last 5-7 years. Besides panel radiators have high emissivity and a well-heated room. However, they are not suitable for heating systems high pressureBecause it can withstand no more than 10 atmospheres.
Aluminum devices consist of separate sections and also have high emissivity: each section has lateral sipes, which increase the heat transfer area and, consequently, air is heated faster in room.
Panels of aluminum resistant to pressure differentials in Russian heating systems and the pressure was kept at break up to 50 atmospheres. In addition, they are durable and can last 20-30 years. Their only drawback - just susceptibility to water with a high pH. In heating systems with a pH greater than the critical level of 10-11, for example, in some areas of the Leningrad region and Ryazan, aluminum radiators do not live more than a year. However, for today's new buildings is a problem still rare, because most new homes are equipped with individual heating units with a good water treatment.
The economy segment has a third option, which is sometimes used in especially budget properties with heating wiring stoyakovoy - Steel convectorsThat cost is much cheaper than other developers heating devices. The main and perhaps the only of advantage - the possibility of welding stainless steel tubePassing through the convector, a riser pipe. Thus the possibility of leaksWhich may appear in the joints of other cells, is reduced to zero and convectors serve up to 25 years. Otherwise, they are inferior to the steel panel, and especially aluminum radiators and the level of heat transfer, and the operating pressure.
In new business-class heaters, of course, can not be found, but the steel and aluminum battery - it is, and often manufactured in Europe. Specifications of European instruments are not generally different from the Russian. The difference in the details. For example, the majority of domestic manufacturers, with the exception of some of the major brands, cover radiators one coat of paint. While European battery are multi-phase training and double staining, allowing longer retain the color, do not fade and do not lose their appearance over the years.
In general, the majority of buyers of apartments in new buildings, regardless of the class of property, change the radiators, installed by developers.
If the economy segment of the reason is questionable as instruments and their poor appearance. A business-class housing concept for the future interior designers often develop, which by default include an estimate of the replacement battery, because the standard options may not fit into the apartment style.
Secondary
The apartments on the secondary market range of different batteries. Especially if the previous owners of the property have not changed radiators, installed by the developer.
For example, the typical houses built in the eighties of the last century, can be found in the classic iron batteries. If you encounter such a rare instance, take a picture of it to memory as an endangered species and change. The fact that the radiators are made of cast iron, which stood in every apartment in the USSR, much inferior to modern heating devices from a technical point of view. They are slightly warm, consume a lot of water and slow to respond to changes in temperature coolant. And, despite the apparent reliability, cast-iron battery can corrode due to the acidity of the water.
Homes built in dashing the nineties, where the previous tenants had not changed the batteries, can already be found convectors. By and large they are only slightly different in appearance from modern steel convectors. Pros and cons are the same: the minimum probability of leakage, long life, the average operating pressure and poor heat transfer.
In the early 2010s among developers economy class housing became popular steel panel radiators and, if the apartment was not repairsNew owners can catch them.
The apartment is renovated - is quite another story. Look to your friends: 90% of the rooms are aluminum or bimetallic radiatorsThat could determine how tenants and management company at the time of major repairs at home. Bimetallic radiators are present in the Russian market since the late nineties and are gaining popularity with each passing year. The outer part of the device is made of aluminum, and internal - of the steel, whereby the bimetallic battery easily cope with coolant with a high pH. In this heat transfer, the working pressure and it remains at the reliability of aluminum radiators.
Aluminum and bimetal batteries can be found in business-class apartments in the secondary market, but here most of the products used European manufacturers.
Yet another type of heating elements, which the owners of business-class housing is often installed on their own - Steel tubular batteries. Not a bad option: they can work with pressures up to 10 atmospheres heating for 5-7 years, and the high quality performance of the heating system and longer. In addition, tubular radiators differ unusual design, which can evaluate the new tenants. But the beauty demands of the victims in this case have to sacrifice the heat dissipation, which is 30-40% lower than the aluminum battery, and slightly above the convector.
Anyway, the new owners of the business class apartments in the secondary market often changed radiators together with the interior. While buyers of economy class housing can leave radiators mounted predecessors, if they have a presentable appearance and well-heated.
