Using a heating radiator is one of the most common ways to provide heating to buildings. In the following section, the calculation of capacity, technical specifications, models and brands, how to check them, and the best purchase price for all types of heating radiators are provided.
Guide to Selecting the Heating Radiator
The water in the heater (radiator) in the building's central heating system (engine room) is heated by equipment such as torches and boilers. The heated water in the engine room is directed to different parts of the building by a pump, enters the radiators of each part of the building, and transfers its heat to the environment through the heating radiators. The heat of radiators is distributed through heat transfer and displacement in the air near them. After the air is heated in the vicinity of the blades of the heating radiators, the hot air moves upwards and then the cold air replaces it. This continuous flow of air causes the room temperature to gradually warm up in the winter. They do not have humidity, because heating radiators usually reduce the ability to adjust the temperature and humidity of the room relatively. (Of course, today, if you install and use a radiator thermostatic valve, you can completely adjust the temperature of your environment in addition to saving energy consumption by about 30%)
Note: Due to the accumulation of hot air under the ceiling, the use of radiators is suitable only when the distance between the floor and the ceiling of the desired location is at most 3 meters, and for spaces with a higher ceiling height, the use of Blower heating devices such as fan coils, heater units, fan and radiation heaters, air conditioners, air washers, etc. are recommended.

Types of heating radiators
The types of heating radiators used in residential and office buildings mainly include the following:
Aluminum radiator: Aluminum radiators are produced from suitable A413 aluminum alloy and mainly in diecast form, in blocks of 3, 5, 7, and 10 blades. These radiators are completely stainless, beautiful, stylish, and in terms of price, they include the highest price category among other types of heating radiators. Complete and technical explanations about the types, advantages, and other characteristics of aluminum radiators in the relevant group on the site Damatajhiz HVAC is provided with all kinds of products, sizes, brands, and reasonable prices.
Panel radiator: Panel radiators are included in the group of steel radiators and are a new model of steel radiators that are more beautiful, integrated, light, and stylish than the previous models of steel radiators. They are more and are produced and supplied in panels of 50 to 200 cm.
Radiator or electric heater: Electric radiators have limited heat and are safe, beautiful, silent, and sometimes portable, and all types of metal, glass, and... are produced and supplied.
Plinth radiator: Plinth radiators are installed around the perimeter wall of the building in question and increase the temperature of the environment in winter.
Towel radiator: Towel radiators are usually installed and used in bathrooms. These types of heating radiators also have beautiful and diverse types, sizes, models, colors, and designs that are presented on the Damatajhiz HVAC Group website.
Steel radiator: Basically, steel radiators are produced and supplied as an inseparable block. That is, outside the factory, you cannot add or subtract a blade to them. (But in the case of most Aluminum radiators has this capability.) The width of each blade of the steel radiator is 4.5 cm and each square meter of the surface of the steel radiator under normal conditions and a temperature difference of 60 degrees Celsius (between the ambient air and hot water) entrance to the radiator) has a heat output of about 440 kilocalories per hour. To calculate the number of steel radiator fins needed for each of the spaces in your building, while announcing its dimensions and location, consult with facility engineers or experts of the specialized heating equipment group. Of course, for the weather conditions such as Tehran, Mashhad, Isfahan, Shiraz, Rasht, Kermanshah, Mosul, Kirkuk, Erbil, Aleppo, Damascus, Kabul, etc., provided that the cold air does not penetrate too much inside And the presence of only one wall exposed to the cold outside air, it can be approximately 85 kilocalories for each square meter of useful building in the middle floors of the building, and about 95 kilocalories for each square meter of useful building for the top floor of the parking lot, and also for the unit Those that are located under the roof of the building should be considered about 120 kilocalories. (And usually, for each additional wall that is in contact with the cold outside air, 20% is added to the above heating values.) Now you can multiply the useful space size by the kilocalories required for heating that space. Calculate the amount of heating required for each of the spaces in your building in terms of kilocalories per hour. Finally, by dividing the required heating number of each of the spaces by the heat produced by each blade of your chosen radiator, you will get the number of radiator blades. (The heat produced by each blade of the radiator is specified in the technical specification table of that model.) - We emphasize again the use of Thermostatic valve of the radiator to adjust the air temperature inside in winter will save about 30% of your fuel consumption.
steel radiator and its production process
The steel radiator production process does not require complex technical knowledge, and its steps are common operations in metal industries, including sheet metal (cutting, pressing, and forming), welding (resistance welding and (oxyacetylene) welding), paint coating, and control. It includes the quality and the main materials used are ST12 steel sheets with a thickness of 1.25 mm. Also, in the stage of painting the steel radiators, the choice of common gray or cream color is the responsibility of the manufacturer or the customer.
Types of steel radiators
Each panel radiator block is made of two pressed ST12 steel sheets with a thickness of 1/2 mm facing each other, with hot water flowing between them. Panel radiators are produced and supplied as single convectors or as double convectors (double width).
The type of steel radiator blade is produced from a standard sheet, with a thickness of 1/25 mm in different sizes, which are usually 600 x 200, 500 x 200, and 300 x 200 mm radiators, and the number is 200 in the model. It shows the width of the radiator blades and the number is 600. 500 300 is the distance from the bottom axis to the top of the steel radiator in millimeters. The thermal surface of the 600 x 200 steel radiator is equivalent to 0.31 square meters and the thermal surface of the 500 x 200 radiators is equivalent to 0.26 square meters and the thermal surface of the 200 x 300 steel radiator is equivalent to 0.18 square meters. The connection of the radiator fins to each other can usually be done by welding or by using round left and right ribs only in the factory. (The width of each steel radiator fin is equal to 5.4 cm.)
Steel fin radiators can also create a good heat exchange surface in a relatively small space because they are made in the form of fins.
Advantages and disadvantages of panel radiator
Panel radiators are made of sheet steel and today their use has become popular in most European countries. As the use of panel radiators or panel radiators, which are offered in the steel radiator group, due to their elegance and beauty and more reasonable price It is increasing to other types of steel radiator.
Features and advantages of panel radiators include the following:
More uniformity in ambient heating than finned radiators
Uniform and broad radiation levels and more radiant heat compared to the types of blade radiators (the more the contribution of radiant heating compared to convective heating, the more pleasant it will be in terms of the physiology of the human body.)
Beauty and compatibility with most interior decoration designs
Integrated installation and good sealing
Possibility of installing radiators on both sides of the block
Also, the panel radiator has disadvantages and weaknesses as follows:
Due to the use of steel, there is a possibility of rusting and holes in steel and panel radiators, compared to aluminum types of radiators, especially in wet weather conditions and in the long term.
If the radiator panel is damaged and punctured, there is almost no possibility of cost-effective repair of the panel and steel radiators. (The entire panel must be replaced)
It is not possible to increase or decrease the thermal capacity of the radiator to the panel. (In such cases, the thermal capacity can be increased by branching off the heating pipe and using a separate radiator panel.)
choice of aluminum, panel, and steel radiators
According to the dimensions of the installation site and calculating the heat loss of the desired space, you can choose the number of radiator fins you need according to the shape, dimensions and heating rate of each radiator model, and in the case of aluminum, steel and panel radiators, According to the required heat, the type and length of the panel radiator should be selected by sales experts or facility engineers using the technical specifications table for that model.
tips regarding choosing aluminum, panel, and steel radiators
As usual, our emphasis is on the accurate calculation of the building's thermal loads by the software, as well as the verification of the calculation results by a facility engineer, which will definitely reduce your costs during the purchase and implementation phase.
It is necessary to install the radiators near the peripheral and cold walls of the building (under the windows and near the external walls).
Today, considering the high fuel costs on the one hand and also the phenomenon of global warming on the other hand, using radiator thermostatic valves instead of normal valves for radiators is a necessity and a completely smart and economical choice. It reduces the cost of fuel consumption (up to 30%) and your gas bills, and also has a noticeable effect on increasing the life of the engine room and package.
Considering that the working pressure of aluminum, steel, panel radiators, and towel dryers is between 5 and 6 bars, the installation and use of these radiators is not allowed for buildings that have more than 14 floors.
Using the radiator's automatic venting valve facilitates the annual venting of radiators and also reduces the risk of water leaking from the radiator to the furniture.
Regular and timely venting is one of the most necessary principles for maintaining heating equipment, and note that basic and timely airing of the heating system should be done carefully every year at the beginning of the cold season when you have turned off the radiator water circulation pump.
Another point When choosing the required aluminum or steel radiator or panel, please pay special attention to the dimensions of each radiator block in addition to the type, material, model, color, and price of the radiator. so that it does not hit the opening of the window above it during installation or is not placed in front of the electrical sockets installed at a height of 40 cm on the wall.

Electric heater or radiator
As mentioned, the use of electric radiators or electric heaters to provide suitable heat is one of the most popular and favorite choices of heating system consumers due to the ease of operation, high safety, and noiseless operation. It is an addition to the building.
A radiator or electric heater, which is also known as an oil radiator and also an electric heater, has the general shape of a radiator grid and inside it is filled with oil instead of water. The elements placed in the radiator or electric heater cause the oil to heat up and its movement in the radiator fins, and the heating of the radiator fins causes the environment to heat up. The oil in this heat transfer device is permanent and does not need to be changed at any time.
The oil heating element is placed inside the electric radiator and when the oil is heated by the convection system, hot oil is transferred to the top and cold oil to the bottom of the device and this cycle continues continuously. The heat capacity of the oil causes absorption More energy in less volume (compared to water). Of course, compared to a gas heater, an electric radiator has a greater safety and, of course, a higher cost of electricity consumption, and for this reason, it is recommended to be used as additional heating in the bedroom and small to medium-sized rooms, because gas heaters generally And especially the models without chimneys should not be used in the bedroom in terms of safety. Electric radiators mainly have 5 to 15 blades and power consumption of 900 to 2000 watts. Also, electric heaters usually have an automatic thermostat and two heating modes (low and high) and some models have a fan to speed up the distribution of hot air. (Of course, glass radiators are also included in the group of electric radiators.)
The electric radiator is suitable for optimal and continuous heating in small to medium-sized environments and is safer due to the lack of direct connection with the element or heat-generating factors. (Also, some electric radiators have drying towels)
Also, one of the other advantages of all radiators or electric heaters is the ability to move them using the wheels installed in the space where they are placed.
How to choose an electric heater or radiator
A 5 to 7 blade electric heater or radiator can be suitable for a room of 6 to 8 square meters with a ceiling height of about 2.8 meters in not very cold weather conditions.
7 to 9 blade electric heater can be suitable for a room of 8 to 10 square meters with a ceiling height of about 2.8 meters in not very cold weather conditions.
9 to 11 blades electric radiator can be suitable for a room of 10 to 12 square meters with a ceiling height of about 2.8 meters in not so cold weather conditions.
The 11-13 blade electric heater or radiator can be suitable for a room of 12-15 square meters with a ceiling height of about 2.8 meters in not very cold weather conditions.
Buying a heating radiator
Purchasing a heating radiator requires an advertisement and sufficient information in this regard, which has a significant impact on an optimal purchase. As mentioned, heating radiators are produced and supplied in different dimensions and sizes with various materials. If you have visited the market while buying a heating radiator, you will undoubtedly come across dozens of different brands, each of which has its own price, dimensions, color and features. On the site of the specialized collection of Damatajhiz HVAC Group, technical information of dozens of models of heating radiators, from reputable brands with original warranty, has been presented in order for you, dear ones, to enjoy the good feeling of an optimal and smart purchase.
Heating radiator price
Currently, due to the wide variety of products in all product groups, making an affordable purchase is the concern of many consumers. Also, the number of heating and radiator fins affects their price, so the lower the number of fins used in heating radiators, the lower the price. Therefore, we emphasize again, choose the number of blades of each block of radiators you need using the opinion of expert installation engineers or experts in the heating equipment department in the specialized collection of Damatajhiz HVAC Group.
choosing the installation location of radiators
In the winter season, heat is constantly added to the room by the heating radiator, but the room temperature does not rise and this temperature remains somewhat constant. The reason is that most of the heat produced is lost through the cold walls of the building.
Heat losses are done in two ways. One is the heat loss caused by the walls, such as the ceiling, floor, wall, window, etc., and the other is the heat loss caused by the penetration of cold air through the window seams.
In other words, this heat loss is done in any case. Of course, we can reduce the amount of heat loss by using UPVC double-glazed windows and using a thermostatic radiator valve.
The height of steel radiator blocks after installation on the corresponding base is 6 cm higher than the total height of each blade, so when estimating the height required for installing steel and panel radiators, to avoid Pay enough attention to the possible problem with the opening of the windows.
As mentioned before, when choosing any aluminum, steel, or panel heating radiator block, pay attention to its height and length so that it does not collide with the opening of the upper window or electrical outlets installed on the wall.
