Advantages and disadvantages of Oasis radiators
An oasis battery, depending on the material of manufacture, has the following advantages:
- inertness to aggressive substances;
- the ability to install on any heating structures;
- high degree of strength;
- lack of restrictions in use;
- good level of heat transfer, contributing to the rapid heating of the room;
- relatively low cost of aluminum and steel models;
- the possibility of use in multi-story and single-story buildings.
Oasis heating radiators also have disadvantages. Not every user can afford bimetallic models, since their cost is higher than other types. Steel and aluminum products are susceptible to corrosion processes, and also do not have the highest mechanical strength.
The main types
Oasis radiators are made of several materials: steel, aluminum or an alloy of metals (bimetal). Each type has its own scope, lifetime.
Bimetallic
The bimetallic Oasis radiator can be installed on centralized heating systems, as well as in closed systems of private houses. Due to the special design, such products are not harmful to pressure surges in pipes up to 45 atmospheres. In the manufacture of devices used such materials:
- Aluminum. Heat exchangers are made of it, through which heat enters the room. There is a large number of air channels under the decorative panel. They provide a high level of heat transfer.
- Steel. The material is used for the manufacture of the internal structure, inside which the coolant moves. The core is of high quality and characterized by mechanical strength. Due to this design, the liquid cannot contact aluminum parts, so the risk of corrosion is reduced.
In the product line there are 2 models of bimetallic radiators: Oasis 500/80 Premium, GMB. The minimum number of sections in the fixture is 6, but if necessary they can be increased to 12.
Aluminum
Oasis aluminum radiators are characterized by fast heating and slow cooling. They are installed both on centralized and individual heating systems. By the method of manufacturing, the products are injection molded and extrusion. The first option is corrosion resistant. It consists of 4-12 sections. Extrusion devices are small in size and have a smooth surface. Sections in this case consist of 3 blocks interconnected.
The outer surface of the product is coated with a polymer coating that performs a protective function. Aluminum radiators are made taking into account the climatic characteristics of the regions, therefore, are well suited for our country. Warranty period - 15 years. In parallel with such radiators, metal or plastic pipes can be used.
Since the design is collapsible, it will not take much time to install the product. The aluminum radiator can operate at high pressure (16 atm.) At a coolant temperature of 110 degrees. For effective operation of the system, regular air removal is required.
Steel
For the manufacture of Oasis steel radiators, cold-rolled metal is used, the thickness of which is 1.2 mm. A polyepoxy paint is sprayed onto the surface of the panel, which protects it from the negative influence of the external environment and gives a decorative look. Connection models side or bottom. The manufacturer offers fixtures consisting of 2 or 4 panels. Some models are equipped with additional stiffeners.
Sectional or tubular options can be purchased. The first type is difficult to repair, and the second has thin walls. Steel radiators have good heat dissipation, but slowly heat up. The efficiency is about 85%. They are resistant to mechanical damage, but do not withstand the increased pressure inside the pipes, and are also prone to corrosion.
Installation methods
Before starting installation of Oasis heating radiators, you need to determine the installation method of the device. The following methods are used for fixing the product:
- Side. The coolant supply pipe is connected to the upper radiator nozzle, and the outlet is carried out through the lower. If you increase the number of sections, the opposite section of the structure will warm up worse. The heat transfer will decrease. This feature must be taken into account when adding sections.
- Lower. This option is not the most effective, since the efficiency in this case is reduced. This design is suitable for installation in systems where the heating pipe passes under the floor covering.
Which connection method will be used depends on the type of heating system.
Oasis radiator operation
The owner of the radiators must follow the instructions for use. It provides for preliminary preparation of the coolant. It should have a pH in the range of 6.5-8.5, and the maximum heating temperature is 110 degrees. It is also important to adhere to such rules:
- if necessary, or the period of completion of the heating season, the radiator is disconnected from the system;
- since water will remain in the system, you need to make sure that the temperature in the room does not fall below 0 degrees;
- when venting, do not illuminate the air vents with open fire;
- taps installed at the inlet / outlet open smoothly to avoid water hammer;
- filters are installed on the risers that prevent the control and air valves from clogging;
- external cleaning of devices is carried out with soapy water or mild means - it is forbidden to use abrasive powders;
- if there is a need for frequent air bleeding or breakdowns, a specialist consultation is necessary.
After installation, before starting the system, the operability of the radiators and the tightness of the joints are checked.
The main problems in operation
During operation, some problems may occur:
- blockages in the heating pipes;
- air traffic jams;
- reduced efficiency due to improper operation or installation;
- leakage in the places of installation of plugs and regulators;
- incorrect calculation of the number of sections.
Oasis radiators for Russian heating structures are chosen more often than others due to low cost. However, you need to correctly calculate the number of devices themselves, as well as the number of sections in them. If installed incorrectly, the heating devices must be replaced. In addition, you must follow the rules of operation.
