Steel Radiator Experts' Buying Guide and Price List
One of the oldest methods of heating in apartments, houses, and office spaces is the use of steel radiators. It works in such a way that the heat of the steel radiators is distributed through heat transfer and displacement in the air.
After warming the air near the radiator fins, the warm air moves upwards, replacing the cold air. This continuous air displacement causes the room's air temperature to increase gradually. Of course, part of the heating of the radiators is also done by the radiation method.
The water in the panels of the radiator is heated in the central boiler of the building (engine room) using burners and boilers or using a combi boiler inside the unit and then directed to different parts of the building by the pump. After that, this hot water enters the radiator and transmits heat through radiation to the environment.
The most suitable places for installing and operating a radiator are places that do not require precise control of temperature and humidity, as radiators usually do not adjust the temperature and humidity of the environment and even reduce the room's relative humidity.
However, if you install a thermostatic valve, you gain the ability to adjust the ambient temperature in a good way, and not only that, you also save energy and relevant costs.
Note: Unlike aluminum radiators, steel and panel radiators are produced as an invisible block, which means the number of fins cannot be reduced or increased by the user.
Types of Stainless Steel Radiators
The panel type of steel radiator is made of two pressed iron sheets with a thickness of 1/2 mm facing each other, with hot water flowing between them.
Flat steel radiators are produced as single convectors or as two convectors (with twice the width and more heating) in blocks of 50, 60, 80, 90, 100, 120, 140, 160, and 200 cm long.
The sectional type of steel radiator is made of an iron sheet with a thickness of 1.25 mm in different sizes; usually, radiators of sizes 200x600, 500x200, and 300x200 mm are among its types. The number 200 mm indicates the width of the sections, and the numbers 600, 500, and 300 are the distance from the bottom axis to the top of the steel radiator in millimeters.
Steel radiators can create a good thermal surface in a relatively small space because they are made in the form of sections.
Flat/Panel Steel Radiators
Panel steel radiators are often made of steel, and today, their use has become popular in most European countries. The use of panel radiators is increasing due to their greater elegance, beauty, and more reasonable prices than other types of radiators.
Advantages of Panel Radiator
More uniformity in providing ambient heating than sectional radiators
The surface of the uniform and widespread radiation and the heat of the radiator more than the sectional radiator (the greater the share of radiation heating than convection heating, the more Suitable·)
Integrated installation and good sealing
Ability to be installed from both sides
for most interior decoration designs
Disadvantages of Panel Radiator
Due to the use of steel, it is possible to rust and pierce steel radiators in humid environments compared to a variety of aluminum radiators, especially in the long run.
If the body of the panel stainless steel radiator is damaged and pierced, it is almost possible to repair it. (The entire panel should be replaced.)
It is not possible to increase or decrease the length and thermal capacity of each block of steel and panel radiators. (In such cases, the heat capacity can be increased by branching from the radiator pipe and using a separate radiator panel.)
Stainless Steel Radiator Production Process
The steel radiator production process does not require complex technical knowledge, and the production process of its conventional operations in the metal industries, including sheet stages (cutting, pressing, and forming), welding (resistive welding and oxyacetylene), coating, and quality control.
After that, it comprises the water test, and the main materials used are ST12 standard steel sheets with a thickness of 1.2 mm. Also, in the stage of painting steel radiators, a common gray color or electrostatic cream is usually chosen by the manufacturer or the customer.
Factors to Keep in Mind When Buying Steel Radiators
As usual, we emphasize the accurate calculation of the building's thermal loads by the software, and the confirmation of the engineer is required. To buy the most suitable steel radiator that will serve you for a long time. Here are the 4 tips you best keep in mind when buying a steel radiator:
You need to install steel radiators at the cold spots of the building (under the windows and near the outer walls of the building) so the device can deal with the cold more efficiently.
Today, the use of stainless steel radiators thermostatic valves instead of conventional ones is a completely intelligent and economical choice, and high fuel cost of up to 30 % (due to the heavy fuel costs), which will result in a lower gas bill as well as a significant impact on extending the life of the boiler.
The use of an automatic bleeding valve makes it easy for the bleed and, in addition to providing complete heating of your home in the winter, reduces the risk of steel radiator leakage.
Regular and timely bleeding is one of the most necessary maintenance of heating equipment. Note that the moral and regular bleeding of the heating system must be carefully performed every year when the circulator pump is turned off.
To estimate the right heating capacity of a stainless steel radiator consider the following formula:
QT = [(U1 x A1 + ... + U1 x An) x ΔT + (V x 0.0749 x 0.24 x ΔT)] x 4
QT: heating load (heating capacity) of steel radiators in kilocalories per hour.
U1 to Un: the heat transfer coefficient of each of the surfaces between the inside and outside of the building in terms of Btu in / (h ft2 of), which should be determined based on the material of each of the walls using engineering reference tables.
A1 to An: the area of each of the peripheral surfaces of the corresponding unit that transfers heat to the outside of the building. This area (in square feet) includes walls, windows, doors, and ceilings.
ΔT: the temperature difference between the inside and outside of each unit under normal conditions, which is in °F.
V: Total amount of air infiltrating through door or window seams (CFH) in ft3/hr Constant factor 0.0749: air density in conventional conditions in the English unit system. Constant coefficient of 0.24 specific heat capacity of ambient air in conventional conditions in English units.
In the above formula, by calculating the values of all the parameters, you can get accurate results to determine the value of the steel radiator in each of the rooms.
Note: The exact values of U and area A for each of the surrounding surfaces must be considered based on specific details in each building and engineering tables of the heat transfer coefficient.
Stainless Steel Radiator Installation Location
In winter, the steel radiator transfers heat to the room. However, the temperature of the room does not rise, and this temperature often remains constant. The reason is that the heat produced is lost through the walls and the penetration of outside cold air.
Heat loss occurs in two ways. One is the heat loss caused by the surrounding walls of the building, such as the roof, floor, wall, window, etc. The other is the heat loss caused by the penetration of cold air outside through the window seams.
In other words, whether we like it or not, thermal losses occur in buildings. Of course, we can use double-glazed UPVC windows and the use of radiator thermostatic valves; in addition to reducing the amount of heat loss, we can also be completely economical in energy consumption.
The height of steel radiators is 6 cm higher than the total height of each blade after installation on the base, and you might as well keep it in mind when doing your calculations so that the steel radiator height does not collide with the window above it.
Pay attention to the overall dimensions of each panel or steel radiator block you choose according to its installation location in the unit so that the height of the steel radiator does not collide with the window above it and the length of the stainless steel radiator block does not collide with the electrical outlets.
