In this section, we will tell you about the optimal height of the radiator and compare the technical data of foreign product samples and their domestic counterparts. We recommend that you find out the total area of ​​the room and the number of connection points (tie-ins) before starting.

In the domestic market of heating radiators, for a long time, the leadership remained with imported samples demonstrating the highest consumer qualities. Among them you can find such heating devices as the Sira RS 500 or the Global Style 500. In addition to their pleasant design, they are famous for their reliability and durability, they fit perfectly into any interior and at the same time do not cause trouble for the owner. But the last word in terms of the warranty period and technical data remains with the Rifar Monolith 500 model of domestic production.

Heating radiator models with a height of 500 mm

The range of heating batteries is represented by various product series, each of which consists of sections of different heights. The most popular are sections with sizes of 200, 300, 350 and 500 mm, however, only the 500th are considered to be truly practical. One section with a height of 500 mm is capable of heating an area of ​​two square meters, while smaller ones are barely able to heat one and a half squares (for 350 mm). In terms of cost, more expensive blocks turn out to be cheaper even at the stage of purchase. For example, elements with dimensions of 350 and 500 mm differ in price by a maximum of 100-150 rubles, more often the difference goes to amounts of less than 50 rubles, while 350s will be required one and a half times more than their counterparts of 500 mm. From here, already on areas of 50 square meters or more, the difference in final costs can reach at least 10 thousand rubles.

Next, we would like to tell you about the features of a one-piece non-separable design, its unambiguous advantages and implementation features in stores and service centers. At first glance, the impossibility of independently choosing the number of blocks should scare off a potential consumer, but its advantages and possible savings (due to trouble-free operation) in the future clearly outweigh this controversial point in favor of an urgent purchase.

Radiator Monolith 500

Rifar sectional radiators are of particular interest in the heating market. The Russian company of the same name opened their production in 2002 and provided consumers with an opportunity to purchase high-quality, reliable elements for autonomous or centralized heating systems and heat premises of any area.

Criteria for distinguishing radiators Rifar

The Russian company Rifar uses a variety of materials for the production of heating radiators, including high-quality aluminum and special steel. Aluminum products are able to withstand strong changes in temperature, pressure and are designed for heating systems with unstable performance. For the production of bimetallic radiators, steel pipes and aluminum alloy are used. In addition to the material of manufacture, the list of distinctive characteristics includes:

• weight and dimensions;
• number of sections;
• design and color scheme;
• center distance;
• heat power indicators;
• coolant volume;
• material of gaskets when assembling radiator sections;
• section cost.

Features of production

The production of aluminum and bimetallic radiators Rifar is based on the use of innovative advanced technologies and modern equipment from world manufacturers from Japan, Germany, Sweden and Italy, patented innovative proposals and multi-level control at all stages of the production process.

After passing the preparatory cycle, which includes refining, degassing, checking the compliance of the quality of the starting material by spectral analysis, the aluminum alloy is poured into the foundry complex. The production of radiators is based on the injection molding method. It is he who makes it possible to obtain castings of specified sizes and shapes. The machining center carries out the grinding and assembly of the radiators. A strictly regulated assembly process ensures a high tightness of the product.

After testing, the radiators are mechanically marked. In the painting chamber, a robotic arm paints the prepared products in an electrostatic field, and then the paint is polymerized under the influence of high temperatures.

The automatic line shrinks the finished radiators twice. This process allows you to effectively protect the coating of radiators during transportation and installation.

Rifar radiator range

Rifar heating radiators are presented in a wide range of models and include several series:

• it is distinguished by its long length and shallow depth, intended for rooms with large windows and narrow window sills;

Having set out to choose a quality one, the first thing that you will find is a large assortment of different-format products on the market. How not to get confused and buy really worthwhile equipment? Only after studying the offers of the most trusted manufacturers. That is why today we offer to discover Rifar radiators. We bring to your attention the technical features of three popular series of Russian products - Monolit, Forza and Base, as well as feedback from specialists and buyers about the radiators in question.

Monolit

A series of advanced bimetallic heating radiators designed to withstand any harsh environment. The manufacturer assures that the devices are designed to operate at temperatures even up to 135 degrees.

Monolit is perhaps the most sought after line of Rifar products, which has won recognition for its high technical performance. Externally, the radiators of this series are not much different from traditional heating devices, but the main feature of the product lies inside: here the coolant moves through a one-piece non-separable system of steel channels, designed using unique welding technologies. Such a design of the radiator completely excludes the occurrence of equipment leaks and guarantees uninterrupted heating.

Radiator Monolit

But the advantages of Monolit radiators do not end there either. Also among the notable pluses:

• increased anti-corrosion qualities - channels for the movement of the coolant are made of special steel with an anti-corrosion coating;
• maximum heat transfer - achieved due to the complicated geometry of the heat exchange surfaces;
• complete independence from the type of coolant;
• the possibility of using non-freezing heat carriers of any type;
• absence of any joints between sections;
• high strength - the device can withstand nominal pressure up to 100 atm;
• manufacturer's warranty - 25 years.

Advice. Monolit is a suitable option for those who cannot or do not want to deal with various adapters when installing radiators: devices of this line are connected according to the standard G1 / 2 or G3 / 4 circuit without adapters.

Forza

A series of relatively low-cost medium-power Rifar radiators. Depending on the indicator of the center distance, the models of this series can be of three types:

1. B200 - radiators with a center distance of 200 mm. They have a closed rear section - due to this design feature, the batteries are perfectly combined with French windows, which are demanding in terms of aesthetics of the interior.
2. B350 - batteries with a center distance of 350 mm.Often used in rooms with certain height restrictions in the installation area - such bimetallic radiators allow you to keep the style of the space unchanged.
3. B500 - the most powerful models in the series with a center distance of 500 mm. Ideal for large areas with poor thermal insulation - these high-performance batteries are able to provide high-quality heating even in such difficult conditions.

Radiators are designed for uninterrupted operation at temperatures up to 135 degrees and are able to withstand pressures up to 20 atm.

Forza radiator

In the operation of Forza radiators, the main focus is on the maximum allowable heat flux of one section: for models with center-to-center gaps of 200 mm and 350 mm, this value is 136 watts, for 500 mm - 200 watts. The manufacturer's warranty is 15 years.

Base

Another popular Rifar series, presented, like the previous line, with three bimetallic models with different overall dimensions and center distances:

All three radiators can be both basic and special - in the Flex or Ventil modification.

Radiator Base

Base Flex - bimetallic batteries with a certain radius of curvature. Curved models can be installed against a wall with a radius of at least 1450 mm. The company produces devices for both convex and curved working walls. Thanks to the use of innovative Flex technologies, the consumer gets great opportunities in terms of choosing the dimensions and appearance of Base devices.

Important! The curved Base Flex models are not inferior to the basic devices in terms of thermal performance - even after complex manipulations with the shape and size, they retain the operational characteristics of the original product to the fullest extent possible.

Base Ventil - batteries designed for connection to a heating system with a bottom outlet of the coolant. In this case, the role of connecting fittings is played either by an ordinary lower unit with an center distance of 50 m, or by a single valve corresponding to the type and configuration of a specific heating system.

The maximum heat flow per radiator section depends on the center distance: 200 mm - 104 W, 350 mm - 136 W, 500 mm - 204 W. The batteries operate at temperatures up to 135 degrees and withstand atmospheric pressure up to 20 atm. The models can be produced with a different number of sections - from 4 to 14. The manufacturer's warranty for all Base series radiators is 10 years.

Before you - three demanded series of Rifar radiators, differing in a whole set of technical characteristics. Which battery to choose for your heating system - Monolit, Forza or Base - is up to you, but when making such an important decision, do not forget about the above-mentioned product features and be sure to focus on customer and specialist reviews about it.

At the stage of building a house or repairing a heating system, the question arises of the correct and competent organization. Incorrect installation leads to accidents and unnecessary costs. Especially, this must be taken into account in the winter, when you can freeze in an apartment, and in a private house pipes may burst from such drops. First you need to decide on the heating area, the number of windows, the height of the ceilings.

The procedure for calculating sections Rifar Monolith.

The radiator manual contains a description of all technical parameters. Most residents know the formula: per 1 sq. M. you need 90-100 watts. An example is the calculation of heating radiators Rifar Base 500, a room measuring 20 sq. m. The power of one section of the radiator is 204 watts. Applying our formula, we get: 20x100 / 204 = 9.8. This figure means that for a room of 20 sq. M. requires 10 radiator sections. This calculation was made taking into account: one doorway, window, outer wall. In the case of end or corner living spaces, this result should be multiplied by 1 or 1.3.So for a corner room with the same area, we make the following calculation: 9.8 x1.2 = 11.76, that is, 12 sections are required.

Bimetallic radiators Rifar Monolith

Rifar specialists created a new modification of rifar monolit bimetallic radiators specially for rooms with a large area and having poor thermal insulation characteristics. In addition, batteries of this series can be used in extreme conditions, including in the Far North, for which sudden temperature changes are common.
This model differs from other rifar bimetallic radiators in that it is able to warm up large volumes of air in a room in a short time. In this regard, it can be used not only in residential premises, but also in commercial buildings. These radiators will be an excellent solution for shopping and office centers. They can also be used in industrial workshops and warehouse buildings.

One of the distinguishing features of rifar monolit radiators is that they have monolithic construction... Thanks to this, such radiators are protected from leakage. This makes the operation of bimetallic radiators of this modification more reliable, they last longer.

As a feature and at the same time advantages of the Rifar Monolith battery is its ability to work with different types of coolants. Therefore, they can be used in buildings with an autonomous heating system.

Varieties of reefar radiators

If you need a battery with high heat dissipation rates, choosing bimetallic batteries from this company is the right decision. Bimetallic products of Rifar Monolith modification allow provide stable heat indoors under critical operating conditions. They are able to withstand operating pressures up to 20 atm. They can operate at coolant temperatures up to 110 degrees Celsius. For Russian operating conditions, rifar monolit radiators are the best choice. They can be installed as part of not only centralized heating systems, but also one of the elements of autonomous systems. If we talk in more detail about the Rifar line of batteries, we will single out several models:

• Rifar Monolit;
• Rifar Base;
• Rifar Alp.

Steel pipe - the main element of the Rifar battery sections. It is cast with high pressure aluminum alloy. This ensures high strength characteristics of these products and excellent casting properties. The product of a monolithic type, which is obtained during the production process, allows achieving high heat transfer from the Monolith series radiators with a good safety margin of the product.

Among all models of radiators offered by the company, the Rifar Monolith battery has the best technical characteristics.Also, rifar monolit radiators are characterized by a high degree of fire resistance and resistance to corrosion processes. In the process of their manufacture, a unique technology for assembling collectors is used, which are made of durable steel. Steel ducts are not connected using nipples, as is the case with heating devices from other manufacturers, but using a unique welding technology. The result is non-separable design.

Benefits of Rifar Monolith

The most important advantages of Rifar Monolith batteries are their reliability and durability. The working pressure movement for metal instruments is 70 atm. Another feature of these radiators, which is worth knowing for those who are interested in this heating product, is an even number of sections. Their number can vary from 4 to 14.

Radiator options Rifar

Rifar bimetallic radiators can be made in various versions:

Flex - in this version, the battery can have any radius of curvature. This allows it to be conveniently placed side by side behind convex and concave walls. The use of special brackets ensures easy installation of such a heating device along the wall with a minimum radius of at least 1300 m.

Ventil - a feature of this version of bimetallic batteries is the presence of a lower connection in which a thermostatic regulating valve is built.

Market positioning

Any businessman starting his own business in a sector of the market that has long been divided between players must, willy-nilly, think over his positioning, ask himself: how exactly can I attract a buyer against the background of competing solutions?

In the case of the hero of our article, the stake was made on reliability. The business card of the manufacturer, his, so to speak, top solution is bimetallic heating radiators Rifar Monolith.

These radiators are mounted with steel pipes only. Why? You will understand by learning more about them.

Before giving their characteristics, let us mention the normal parameters of the coolant in the heating system at the peak of frost:

• Temperature - up to 95 degrees Celsius.
• Pressure - not higher than 4.5 kgf / cm2.

In the supply pipe of the heating main, the parameters can reach 140C and 7 atmospheres, however, due to mixing in the elevator unit, the supply water makes up only a small part of the volume of the coolant entering the batteries. And now - a close-up view of the characteristics possessed by bimetallic heating radiators Rifar Monolit 350 and Monolit 500 (the difference is only in the center distance of the connections).

• There are no intersection joints. Monolith, remember? One potentially problematic spot.
• Plugs with adapters for 1/2 or 3/4 threads are not required. Radiators are supplied with ready-made threads in standard sizes. Another vulnerability has been fixed. DIY installation is somewhat simplified.
• The coolant ducts are made of steel with increased corrosion resistance... No, this is not stainless steel; but under normal operating conditions, the manufacturer assures us that there will be no rust. Another problem with the shoulders.
• The maximum operating temperature is 135C. Obviously excessive, given that the current SNiP prohibit the supply of ANY liquids with a temperature above 95C to the house.

Please note: in fairness, in reality, this rule is sometimes violated. First of all, during extremely cold winters: the houses of some projects in the North simply cannot be heated otherwise.

• Finally, the working pressure. Recall that the norm for aluminum and many bimetallic radiators is 16 atmospheres. 25 kgf / cm2 is considered a very good indicator, 35 - excellent and clearly excessive.

Monolith Rifar bimetallic heating radiators are designed for an operating pressure of 100 atmospheres, and are tested at 150.

With this list of characteristics, the manufacturer gives a quarter-century guarantee for the entire line (against a maximum of 10 for most manufacturers).

The Monolith line includes two standard sizes - 350 and 500 mm. Both are shown in the photo.

The sections, we recall, do not disconnect, so it is better to immediately choose a radiator of the required length... Radiators are available in lengths from 4 to 14 sections. Thermal power - 196 watts for a section with a height of 577 millimeters and 134 - for a section with a height of 415 mm (between the supply axes, respectively, 500 and 350).

Finally, the recommended market price for one section: 500 mm - 580 rubles, 350 mm - 570 rubles. Against the background of all European solutions in terms of price / functionality ratio, it is an absolute hit.

Chinese products and other domestic solutions can be taken only and extremely cheaply.
