The products of the Russian company "ROSTerm" are intended for the installation of heating systems in residential buildings and commercial buildings. Steel panel radiators of this brand are distinguished by an attractive modern design and reliable operation. They have become worthy competitors of foreign analogues of heating appliances.
Features of ROSTerm radiators
ROSTerm steel radiator is the best combination of heat transfer, ease of installation, attractive design and affordable price. The products of the Russian company pass a special control system. The enterprises have laboratories for checking the quality of each batch of heating devices. Products are exposed to pressures up to 13 bar, which is 4 bar higher than their working indicator.
Panel-type batteries are made of cold rolled steel sheet by stamping. The coolant circulates inside the structure through the channels, heating the metal. Convection ribs are welded to increase heat transfer. The number of panels and U-shaped plates depends on the model. An increase in the design leads to an increase in the efficiency of the device, but at the same time its cost increases.
Radiators, consisting of several panels, are equipped with decorative plates on the sides, and a grille is installed on top. Welding fins from thin steel plates increases structural productivity by 40%. The manufacturer produces batteries with side and bottom connection. The latter option allows you to hide the heating pipes in the floor. Steel is a material sensitive to corrosion. To prevent rust, the products are coated with a special composition. Painting takes place in 4 stages:
- broom degreasing;
- phosphating;
- primer of products;
- application of enamel.
One of the features of the products is sensitivity to operating conditions. They are not intended for installation in rooms with high humidity - bathrooms, greenhouses or pools. When using the instruments in a humid microclimate, the manufacturer warns about the withdrawal of the warranty and the reduction of the estimated service life. ROSTerm products are sold assembled.
Specifications
Steel panel batteries have gained popularity due to their attractive design and high heat dissipation. ROSTerm heating radiators in technical characteristics are not inferior to competitors, and in some parameters they surpass them:
- working pressure - 9.5 bar;
- maximum pressure - 13 bar;
- coolant temperature - 110 ° C;
- the recommended pH value of the coolant is 8-9.5;
- connection size - 1/2 ″;
- dimensions - length 400-3000 mm, height 200-900 mm;
- center distance - 246, 346, 446, 546, 846 mm.
The high quality of the products is indicated by the thickness of the steel sheet, which is 1.25 mm. Convective plate of products 0.44 mm. The main color of the devices is white.
Advantages and disadvantages
When choosing heating appliances, their advantages and disadvantages are considered. The advantages of steel panel structures include:
- Room heating occurs when heat is transferred from the panel and convectively.
- The batteries are notable for their small capacity; the system does not require a large volume of coolant.
- The simple design and significant thickness of the panels ensure long-term operation of the devices.
- Nice design, ergonomic design and shallow depth of panels.
- Affordable cost of products.
- Simple installation that you can do yourself.
Disadvantages:
- Low corrosion resistance.
- Sensitivity to water hammer and pressure surges.
- Limitations of working pressure do not allow them to be installed in systems where the parameter exceeds 9.5 bar.
The existing disadvantages are compensated by the advantages of the products and the observance of operating conditions.
Notation system
ROSTerm products are marked with a combination of numbers and letters:
- the first digit is the number of battery panels;
- the second digit is the number of convective plates;
- the third and fourth digits are the dimensions of the model (height and length).
For example: ROSTerm 22 radiator type 500 × 500 - a model with two panels and two convective plates, height - 500 mm, length - 500 mm. This design is most popular. It provides optimal heat transfer performance with average dimensions and battery weight.
Additional information is the connection method. Products with side mounting are marked with the letter "K", with side and bottom - "KV".
ROSTerm radiator selection rules
Among the main criteria that you need to pay attention to when buying:
- Heat transfer - the characteristic allows you to design the required number of devices. This is the main parameter of the battery that determines the efficiency of heating. The average operating indicator should be 100 watts per 1 m2 of room.
- Maximum pressure - the parameter determines the scope of the product. In multi-storey buildings, the pressure reaches 9-10 Bar, and in individual systems 5-6 bar.
- Dimensions - the dimensions of the radiator are important when choosing a mounting location. They give an idea of the required free area. It is important to consider the center distance - the length of the section between the input and output collector.
- Connection method - the buyer can choose the best option - side or bottom connection.
Significant factors are the design and cost of the devices. ROSTerm products are distinguished by attractive stylish appearance and affordable price. The cost of products depends on the type and size of the model.
Installation of radiators
Heaters are equipped with everything necessary for quick and easy installation. The kit includes:
- brackets;
- fasteners;
- stub;
- air vent (Mayevsky crane).
Battery installation work begins after finishing the wall. To prevent mechanical damage, it is recommended to remove the protective film after installation. The selected area is marked using the building level. Mounting locations for brackets are marked. Holes in the wall are drilled under the hardware. The brackets are securely fixed with dowels. Mounting brackets of a radiator fasten on them. It is recommended that a thermostatic valve with a head be installed between the heating pipe and the battery. This will allow you to control the temperature in the room.
Heaters are compatible with single pipe and double pipe systems. Depending on the features of the circuit, the connection nuances differ. When installing the device in a single-pipe system, a bypass must be inserted between the supply and return lines. This is a prerequisite for connecting a thermostat. The best connection option, which will provide passport heat transfer indicators, is to connect the supply pipe from above and the discharge from below.
A check valve is mounted on the return line. Models with a lower connection are equipped with a thermostatic valve; a thermal head is screwed onto it. After connecting to the heating circuit, a plug is installed in the lower pipe, and in the upper air vent. The system is filled with water. In the process of filling air from the Mayevsky crane.To exclude rapid wear of the devices, the manufacturer prohibits the discharge of water after the end of the heating season. The fluid is drained only in case of emergency, when performing repairs.
Fields of application
Heating appliances are designed for use in individual and centralized systems. They can be installed in private and apartment buildings, cottages. Scope of products:
- water heating of residential buildings;
- administrative buildings;
- medical and children's institutions.
Batteries are designed for indoor heating systems. They are compatible with low temperature coolant. For apartments, experts advise using models 22. Large rooms with high ceilings effectively heat radiators of type 33, which have several panels and convective fins.
Range of radiators ROSTerm
The manufacturer’s catalog contains 7 types of radiators. They differ in design features:
- 10 - single-row models with a length of 400-2000 mm without convector;
- 11 - there are a number of convective plates fixed by spot welding;
- 20 - two heating panels to increase heat transfer;
- 21 is a variant with two plates and a U-shaped convective crate between them;
- 22 - model with double plates and fins, heat transfer from 564 to 10887 W, depending on size;
- 30 - three rows of steel panels with a circulating coolant;
- 33 - the device with maximum efficiency, has the largest dimensions, weight and heat transfer.
Models 10, 20 and 30 of the type from the company "ROSTerm" radiators related to hygiene products. The absence of a convective grill simplifies battery care.
Panel radiators are an improved version of cast iron batteries. They heat the room and become part of the interior.
