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 attractive modern design and reliable operation. They have become worthy competitors of foreign analogues of heating devices.
Features of radiators ROSTERM
Steel radiator ROSTERM is an optimal combination of heat transfer, ease of installation, attractive design and affordable price. The products of the Russian company undergo a special control system. The enterprises have laboratories to check the quality of each batch of heating devices. Products are exposed to pressures of up to 13 bar, which is 4 bar higher than their working value.
Panel type batteries are made from cold rolled steel sheet by stamping. The coolant circulates through the channels inside the structure, heating the metal. Convection fins are welded to increase heat transfer. The number of panels and U-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 grill is installed on top. Welding ribs made of thin steel plates increases the productivity of the structure by 40%. The manufacturer produces batteries with side and bottom connections. The latter option allows you to hide the heating pipes in the floor. Steel is a corrosion sensitive material. To prevent the appearance of rust, the products are coated with a special compound. Painting takes place in 4 stages:
- degreasing the broom;
- phosphating;
- priming of products;
- applying enamel.
One of the features of the products is their sensitivity to operating conditions. They are not intended for installation in damp areas such as bathrooms, greenhouses or swimming pools. When using devices in a humid microclimate, the manufacturer warns about the withdrawal of the warranty and a reduction in the estimated service life. ROSTERM products are sold assembled.

Advantages and disadvantages
When choosing heating devices, their advantages and disadvantages are considered. The advantages of steel panel structures include:
- The room is heated by transferring heat from the panel and convectively.
- The batteries have a 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 construction and shallow panel depth.
- Affordable cost of products.
- Simple installation that you can do yourself.
Disadvantages:
- Low corrosion resistance.
- Sensitivity to water hammer and pressure surges.
- Working pressure limitations do not allow them to be installed in systems where the parameter exceeds 9.5 bar.
The existing shortcomings are compensated by the advantages of the products and the observance of the operating conditions.
Designation system
ROSTERM products are marked with a combination of numbers and letters:
- the first digit is the number of battery panels;
- the second number is the number of convective plates;
- the third and fourth digits are the dimensions of the model (height and length).
For example: radiator ROSTERM 22 type 500 × 500 - model with two panels and two convective plates, height - 500 mm, length - 500 mm. This design is the most popular. It provides optimal heat transfer performance with an average size and weight of the battery.
Additional information is the connection method. Products with side mounting are designated 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, which determines the heating efficiency. The average working indicator should be 100 W per 1 m2 of the room.
- Maximum pressure - the parameter determines the scope of the products. In multi-storey buildings, the pressure reaches 9-10 bar, and in individual systems 5-6 bar.
- Dimensions - The dimensions of a radiator are important when choosing a mounting location. They give an idea of the required free space. It is important to consider the center distance - the length of the section between the inlet and outlet manifolds.
- Connection method - the buyer can choose the best option - side or bottom connection.
The design and cost of the devices are significant factors. ROSTERM products are distinguished by their attractive stylish appearance and affordable prices. The cost of products depends on the type and size of the model.
Installing radiators
The heaters are supplied with everything you need for a quick and easy installation. The kit includes:
- brackets;
- fasteners;
- stub;
- air vent (Mayevsky crane).
The installation of the battery begins after the completion of the wall decoration. To prevent the occurrence of mechanical damage, it is recommended to remove the protective film after installation. The selected area is marked out using a building level. The attachment points for the brackets are marked. Holes are drilled in the wall for hardware. Brackets are securely fixed with dowels. The radiator mounting brackets are attached to them. It is recommended to install a thermostatic valve with a head between the heating pipe and the radiator. This will allow you to control the room temperature.
The heaters are compatible with one-pipe and two-pipe systems. Depending on the features of the circuit, the nuances of the connection differ. When installing the device in a one-pipe system, a bypass must be cut in between the supply and return lines. This is a prerequisite for connecting a thermostat. The optimal connection option, which will provide the passport indicators of heat transfer, is to connect the supply pipe from the top, and the discharge pipe from the bottom.
A shut-off valve is mounted on the return line. Models with bottom 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 branch pipe, and in the upper air vent. The system is filled with water.In the process of filling, air is released from the Mayevsky tap. To exclude the rapid wear of the devices, the manufacturer prohibits the drainage of water after the end of the heating season. The liquid is drained only in the event of an emergency, when performing repairs.
Applications
Heating devices 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.
The batteries are designed for closed heating systems. They are compatible with low temperature heat transfer fluid. For apartments, experts advise using model 22. Large rooms with high ceilings are efficiently heated by type 33 radiators, which have several panels and convective fins.
Range of radiators ROSTERM
There are 7 types of radiators in the manufacturer's catalog. They differ in design features:
- 10 - single-row models 400-2000 mm long without a convector;
- 11 - there are a number of convective plates fixed by spot welding;
- 20 - two heating panels to increase heat transfer;
- 21 - a variant with two plates and a U-shaped convective lathing between them;
- 22 - model with double plates and fins, heat dissipation from 564 to 10887 W, depending on the size;
- 30 - three rows of steel panels with a circulating heat carrier;
- 33 - a device with maximum efficiency, it is distinguished by the largest dimensions, weight and heat transfer.
Models 10, 20 and 30 of the ROSTERm company are radiators related to hygienic products. The absence of a convection grille simplifies battery care.
Panel radiators are an improved version of cast iron batteries. They heat the room and become part of the interior.
