The heating system in each house is formed from a coolant, a heat source, radiators and a pipeline. A common heating unit or boiler houses are the main sources of heat in centralized highways. To heat country houses, owners must first purchase a boiler, from which a piping system will be carried out. Batteries get, given the large number of parameters. STI heating radiators in the domestic market are rapidly gaining popularity.
General characteristics of STI batteries
STI radiators are manufactured by an Italian manufacturer that has specialized in the manufacture of heating equipment for over 30 years. Products are fully consistent with quality requirements, standardization is made according to the standards of European countries. An additional advantage is reasonable cost. STI radiators have been imported into the Russian Federation since 2013. Today, products occupy about 56% of the total heating equipment market.
The Italian company produces radiators in bimetal coating, aluminum and cast iron. Also, regulating and stop valves are supplied in large volumes to the Russian market.
The company is developing new heating equipment that combines the advantages of all modifications. At the manufacturing stage, all products undergo a three-stage quality control.
Advantages and disadvantages
Advantages of heating equipment STI:
- upon purchase, the manufacturer gives a guarantee for its products for 15 years;
- the equipment fully complies with GOST No. 31111-2005;
- STI radiators are universal in their use, they can be installed in centralized and autonomous heating systems;
- each unit is completely tight, as evidenced by a multi-stage verification system;
- attractive design;
- high-quality and durable casting of batteries eliminates the possibility of leaks, and also favorably affects the duration of the operational period;
- in order to increase resistance to mechanical damage, STI aluminum and cast iron radiators are powder coated in several layers;
- STI bimetal heating radiators are equipped with thickened walls of steel channels, which allows them to withstand water shocks and high pressure in the heating system;
- In bimetallic radiators, cast steel collectors are installed to increase the durability and strength of the structure.
When choosing radiators, it is important to give preference to models adapted to the technical parameters of the heating network.
Varieties of radiators Sti
STI batteries are made from bimetal, cast iron and aluminum. Radiators made of different materials have several modifications, so the consumer will be able to choose a design that meets all the technical parameters of the heating system.
Aluminum radiators
STI Thermo is coated with a high polymer composition with anti-corrosion components. All segments are resistant to the effects of salt, alkaline and acidic environments, they do not form corrosion.
Specifications of aluminum models STI Thermo:
- The height, width and depth of each section are 380/580 * 80/100 * 80/80 mm, respectively.
- Permissible operating pressure of 1.8 MPa.When choosing radiators, it is necessary to familiarize yourself with the indicator of the maximum level of pressure of the coolant, especially when connecting the device to the central heating pipeline.
- The weight of each section ranges from 1.12 to 1.35 kg.
- The maximum allowable temperature is +110 degrees.
- The volume of each section varies between 0.24-0.42 liters.
- The heat transfer, depending on the model, reaches 120-204 watts.
Of particular note is the STI Grand Thermo. It has the following specifications:
- Operating pressure 1.8 MPa.
- Height * depth * section width - 580 * 100 * 80 mm, respectively.
- The maximum allowable working temperature is +110 degrees.
- The weight of each section is 1.31 kg.
- The heat dissipation of each section is 205 watts.
- The volume of one section is 0.41 liters.
STI Classic and STI Grans models with similar specifications are available.
Bimetal batteries
Models made of bimetal deserve special attention due to their increased strength and the possibility of use in a central heating system. With increased pressure, the structure does not deform, the tightness is not broken.
The radiator frame is made of bimetal by welding, is a tubular structure made of carbon steel. A steel collector, which is characterized by increased heat transfer, is placed in a cast aluminum shell of high strength. Due to the absence of contact of the coolant with aluminum, the duration of the service life is significantly increased.
The most popular model is the STI Grand. It has the following specifications:
- Height * depth * width of each section is 570 * 90 * 80 mm, respectively.
- The working pressure of the coolant is 2.4 MPa.
- The weight of each section is 1.8 kg.
- The highest permissible coolant temperature is +110 degrees.
- The volume of each section is 0.2 liters.
- The heat transfer rates of each section are 195 watts.
Before purchasing bimetallic radiators, it is important to make sure that the structures will withstand pressure drops in centralized highways.
Cast Iron Radiators
The product line of cast-iron radiators is represented by the NOVA-500 model. This appliance is adapted for domestic heating systems; it can also be integrated with autonomous heating systems. Cast iron batteries are installed in industrial, recreational and public facilities.
The design has a concise appearance and small dimensions, it has an acceptable cost. The heat transfer of STI cast-iron radiators is 36% higher than that of analogues. The minimum operating life reaches 50 years. Radiators are not afraid of corrosion and undemanding to the composition of the coolant.
Technical characteristics of NOVA-500:
- Height * depth * width of each section 580 * 85 * 60 mm, respectively.
- Permissible working pressure 1.2 MPa.
- The weight of each section is 4.2 kg.
- The most admissible temperature of the heat carrier is +130 degrees.
- The volume of each section is 0.52 liters.
- Heat dissipation - 150 watts in each section.
Batteries consist of 7-10 sections, which are connected by sealing heat-resistant rings of polymer materials.
On the Internet you can find mostly positive reviews about STI radiators. The most noteworthy is the Nova-500 model. This is due to the fact that it is best optimized for domestic operating conditions and technical characteristics of heating networks. Cast iron products are considered a classic version of radiators, which have a large number of advantages, including an aesthetic appearance.
