One of the components of the heating circuit is a radiator. Manufacturers offer them for sale in a wide range, which is why even specialists sometimes find it difficult to choose. If we look at the statistics, then one of the most bought are Oasis batteries, radiators of this manufacturer are of high quality and reasonable cost.
How to make a choice
Having visited the stores of the corresponding goods, you can meet the devices that are most often manufactured in China, Russia and Italy. Many of them are made for highways, which are characterized by high pressure and long length. This is typical for heating systems in Russia. The technology provides a variety of solutions for Oasis radiators, this may be the number of collectors, the method of fastening elements, and so on. That is why sectional and panel models are presented for sale.
Characteristics of bimetallic models of radiators of the Oasis brand
Oasis products are quite common on the market; radiators of this company are bimetallic and aluminum. In order to deal with the pros and cons of products, you need to familiarize yourself with the overview of the characteristics. For example, bimetallic batteries are made of steel and aluminum. Steel forms the basis of gratings and internal bulkheads. A feature of these models is that they are all composite. This allows you to increase the number of sections to the desired value, which depends on the conditions. Such radiator options are designed for at least 30 atmospheres, so they are not afraid of pressure surges.
Among the advantages can be identified:
- inertness to aggressive substances;
- lack of restrictions in use;
- increased strength.
As for the latter characteristic, it can be noted that bimetallic radiators are able to undergo any water hammer in the system. However, there are also disadvantages, one of them is expressed in a higher cost compared to peers.
Why choose bimetal
Such radiators are chosen because of the all-steel collector; manufacturing technology, which is injection molding; as well as a small volume of coolant, which provides high energy efficiency and low inertia. Bimetal heating batteries are manufactured according to a certain technology, which provides for the application of resistant paint in two layers at the final stage. As a result, it is possible to get a perfectly white color.
Reviews of steel radiators
In the manufacturing process of such batteries, low carbon metal is used, subjected to special heat treatment, degreasing and applying a protective layer. Such batteries are available in several versions, they can be supplemented with stiffeners. According to customers, such batteries are sectional and tubular, the latter are less impressive wall thickness, while the former can not be repaired, but are characterized by increased strength.
Their cost is much higher, and the elements are connected by welding. Customers love the high efficiency, which reaches 87%. It should also be noted the low inertia, which is expressed in slow heating and fast cooling, which is also characteristic of aluminum radiators. Users note that steel radiators are subject to corrosion, so it is not recommended to drain the coolant during the off-season. If you want to choose such heating batteries, then you should take into account the specifics of pressure testing, the acidity of the medium and the nominal pressure. Steel radiators are suitable for private buildings, as well as houses with individual heating.
Reviews of aluminum radiators
Quite often, consumers today choose Oasis aluminum batteries, radiators of this type are made by injection molding, the walls have a more impressive thickness. If the technology involves the use of extrusion, then there is no way to change the number of sections. As users emphasize, the Oasis aluminum radiator has a protective polymer layer on the outer surface, and copper elements are present in the circuit. The heat transfer level is maximum, and if you install such a radiator in a closed system, then fuel savings can be 30%. Users emphasize that with the help of aluminum radiators, it is possible to achieve a fairly quick heating of the room.
Negative characteristics of aluminum batteries
Oasis radiators made of aluminum are sensitive to high pressure, so they can be operated at 16 MPa or less. The mechanical strength of such products is not high enough, since the metal is soft, so care must be taken during operation. When using aluminum batteries, it is necessary to bleed air from the circuit from time to time, if this is not done, then there is a risk of an increase in the concentration of hydrogen in the pipes. Among other things, the devices must be handled as carefully as possible, because the protective layer can be damaged. The described products can be installed in autonomous systems, since the central heating pipes create conditions that are not suitable for them. Common advantages are light weight and attractive appearance.
Specifications for some models
Oasis radiators, the reviews of which you could read above, are offered for sale in a large assortment. Among the most common models, 350/80 (6) can be distinguished, which is a bimetallic product capable of heating an area of up to 10 m 2 . If necessary, the Oasis bimetallic radiators can be supplemented with sections. The dimensions of the described model are 413 x 80 x 80 mm. As for the nominal pressure, it is 25 MPa, while the temperature of the coolant is 110 ° C. The number of sections in this model is six, for one of them you will have to pay 385 rubles.
If you wish, you can choose an aluminum radiator brand SV - 500/12, which is prefabricated and is able to heat the room up to 24 m 2 . The dimensions of the model are 580 x 80 x 80 mm, but the nominal pressure is much less than the above model and is 10 MPa. The temperature of the coolant can reach 100 ° , the number of sections in the model varies from 4 to 12, and the cost of one of them is 375 rubles.
Oasis products are offered in a wide assortment today. Radiators of this manufacturer can be steel, one of them is OV - 11/3/04, the dimensions of which are 400 x 300 x 68 mm. This panel radiator has a bottom connection. And he can effectively heat a room with an area of 8 m 2 . The nominal pressure that the radiator is able to withstand is 16 MPa. As for the maximum temperature of the coolant, it is 120 ° C. The radiator has one section, for which you will have to pay 2200 rubles.
Performance Reviews
Oasis radiators are popular with modern consumers for the reason that they have many advantages. Buyers are attracted by the excellent technical characteristics of bimetallic models. Due to the fact that the heating system in a city apartment can give out any surprises by the type of pressure drops, the presence of aggressive additives in water and water shocks, the best option, according to buyers, is the bimetallic model. Such radiators cost a little more, but you can not be afraid of leaks, and the service life is quite high, it can reach 15 years.
Oasis radiators, reviews of which are often quite positive, are popular with consumers for the reason that they are a good combination of price and quality. Some believe that this manufacturer is one of the leaders in this field. A number of buyers are quite satisfied with the steel models that are installed in autonomous systems and have been working flawlessly for several years. The heat transfer in these models is high. And the appearance is quite attractive, which is especially noticeable after the cast-iron radiators were in the house.
Conclusion
Oasis heating radiators may turn out to be an overhead purchase, but after some time you will realize that such batteries are ready to last a long time, and during operation they do not require repair. In terms of parameters and weight, they are among the best.
