💨 Cast Iron Radiators: types, advantages popular models

If you start the installation of heating, cast iron radiators can be an excellent choice. Such products have a number of indisputable advantages. They are presented in a large range and have different specifications. We offer to meet their design and features.

Design and operation of cast iron radiator

The composition of the cast iron radiator consists of several identical sections. Each element is molded individually in the factory. Channels formed within the sections circular or elliptical shape. During assembly, the sections are connected together by means of nipples. The joints are sealed by means of heat-resistant rubber or paronitovye gaskets.

In operation, the cavity in the cast iron radiators are filled with coolant. Last gives heat the metal, and that, in turn, to the surrounding air.

The main types of cast iron radiators

Most of the cast iron radiators has a section structure. They differ in the number of channels. there are:

• single-channel. Finding limited use. High enough products. Mounted advantageously in industrial areas with high ceilings;
• two-channel. Most widely;
• three- and four-channel. They are made mostly to order. Characterized by a large thermal capacity and depth.

performance specifications

The main operating parameters of the cast iron radiators is attributed:

• heat capacity. Depending on the model, one section can produce 100-160 watts. Thus the transported fluid must be heated to temperatures at least 70 ° C;
• dimensions. Dependent on the required heat output and the number of sections. The height can vary between 0,35-1,5 m depth of 5-15 cm.;
• operating pressure. Typically 9 atm., But some models are able to operate up to 15 atm .;
• capacity. It depends on the design characteristics of the battery. On average 0.9-1 liter.

Advantages and disadvantages

The main advantages should include:

The disadvantage is:

Whose products should be trusted: the leading manufacturers

Performance and service life of radiators depends on the manufacturer. Leading positions traditionally occupied by the production:

1. Minsk heating equipment plant (Belarus). The enterprise has made MS series, an analogue which is a Soviet battery. Compared with the prior art, they have a more advanced design.
2. "Santehlit". The Russian manufacturer MS series is available batteries with improved technical parameters.
3. Viadrus. Products Czech manufacturer has a modern design and compact size. Cast iron radiators are in need of painting.
4. Demrad. Turkish manufacturer offers products of different sizes, with modern design.
5. demir dokum. Turkish producer Products characterized by high emissivity. Issued in retrostile.
6. Konner. Chinese cast-iron radiators are fully adapted for use in the Russian heating systems.

PEA FM2 (CHERAD): 4,8 / 5

Allow installation in private homes and high-rise buildings. As the coolant can be used water and steam. Have a different number of sections: 5-11, depending on the desired heat transfer. Thanks to the original design harmoniously fit into any decor.

One section weighs 4.5 kg, and has a capacity of 0.7 liters. Have a depth of 100 mm and a height of 300 mm. Width 80 mm section. Designed for a maximum temperature of 250 ° C transported coolant. Working pressure up to 15 atm.

Some owners say the leak shortly after the start of operation. The integrity of the structure must be checked before installation.

Review of PEA model FM2 (CHERAD):

Choose cast iron radiators: the basic criteria

to mount heating system to cope with the tasks assigned to it, a number of factors to consider when choosing. Each of them defines the operational characteristics of radiators. We offer to meet them in more detail.

By the number of channel sections

The number of channels does not significantly affect the functionality of the device. For premises often choose two- and three-channel design. The latter have a greater depth.

According to the thermal power

So the room was warm and comfortable, installed radiators must have sufficient thermal capacity. Usually the technical documentation for each product, this parameter is specified for one section. To find the value of the total power should be multiplied by the number of sections.

Ask a Question

«For heating 10 m² 1 kW is required. "

When selecting the appropriate option, please note that for rooms:

• ceilings than 3m the required value should be increased proportionally;
• Fiberglass - 15% decrease;
• by heating the coolant below 70 ° C should be added 10-15% for every 10 ° C difference;
• with plenty of radiators, windows should be installed under each.

According to the overall dimensions

Dimensions of cast iron radiators may differ significantly. They depend directly on the stylistic product design and manufacturer. However, the spacing is the same. There is a classification of radiators in size:

1. low. They are 330-400 mm in height when interaxle 300 or 350 mm.
2. average. At interaxle 500 mm have a height of 400-660 mm. Depth sections depends on the manufacturer. The Belarusian devices typically 108 mm, in Russian - 93 mm.
3. high. Their height exceeds 660 mm. Typically, these dimensions are of designer products in retrostile.

In selecting an appropriate embodiment be guided to the installation site. heating radiator should be placed between the floor and the sill. Thus, the lower clearance should be 70-100 mm, the top - 100 mm. This will ensure sufficient air convection. The depth of product must be consistent with the projecting part of the sill.

On-site

Install the heat sink can be wall or floor. The first option is relevant only for load-bearing walls. Because of the heavy weight of iron products require fasteners that can withstand the applied load. The base that does not have sufficient strength may be destroyed.

Attention! Opting for outdoor installation is done and if you do not want to damage the finish of the walls.

Installation of cast iron radiators

That during operation of the heating system did not arise difficulties radiator installation must be performed in compliance with certain rules. The order of work is directly dependent on the design features of the product is installed. We offer to meet them in more detail.

Floor devices

When a floor mount positioned at the right place, providing the desired spatial position of the structure. The entire load in this case takes the floor. Install and secure, the battery is connected to the heating system.

For more information on outdoor units installation procedure can be obtained from the following video:

wall mounted radiators

To fix the wall models in the desired spatial position using special fasteners or metal studs. Their strength characteristics should be sufficient to hold the heavy batteries. In determining the desired position is required to provide a technological gap of at least 60 mm. Radiator It should be arranged vertically.

The procedure for connecting the battery to the heating system depends on its design features. If necessary provided valves restricting flow of coolant or thermostatic valves.

Tip! Given the large weight of products, assembly work together to perform better.
