HEATING RADIATOR

One of the most common methods of heating in residential apartments, offices, schools, and stores is the use of heating radiators. The device works by transferring its heat to the air around it. After the air is heated in the vicinity of the fin, the hot air moves upwards, and then the cold air takes it place. This continuous flow of air causes a gradual warming of the air temperature in the room during cold seasons.

If you want to use a heating radiator to heat up your desired space and you do not know exactly what type of heating radiator works better for you, as what capacity, brand, price, and specifications, stay with us for the rest of this article to answer all questions. We will guide you through the journey of choosing the right types, the calculation of the heating radiator capacity, the purchase price, technical specifications, the best types of heating radiators, etc.

How Does a Heating Radiator Work?

The water is first heated up by the boiler in the engine room. The heated water is then directed to different parts of the building by a pump, enters the radiators of each part, and transfers its heat to the environment through the heating radiators.

The best environment for using heating radiators are places that do not require precise control of temperature and humidity because regular heating radiators usually reduce the ability to adjust the temperature and humidity of the room relatively. However, in modern radiators, if you install a radiator thermostatic valve, you can completely adjust the temperature of your environment, in addition to saving energy up to 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. Otherwise, fan coils and radiation heaters, air conditioners, air washers, etc., are recommended.

Heating radiators

Different Types of Heating Radiators

Types of heating radiators used in residential and office buildings mainly include the following:

Aluminum Heating Radiator

Aluminum radiators, which are made of A413 aluminum alloy and mainly in die-casted metal, are produced in blocks of 3, 5, 7, and 10 fins. These radiators are completely stainless, beautiful, and stylish, and in terms of price, they include the highest price category among other types of heating radiators.

On the website of DamaTajhiz HVAV, technical information about the types, advantages, and other characteristics of aluminum radiators is provided, along with the types of products, dimensions, brands, and appropriate prices.

Panel Radiator (Flat Surface Radiator)

Panel radiators are included in the group of steel radiators and are a new model of steel radiators that are more beautiful, integrated, more lightweight, and stylish compared to previous models of steel radiators and are produced and supplied in 50 to 200-cm panels.

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 also produced and supplied as a single convector or as two convectors.

Flat Surface or Panel Heating Radiator Pros & Cons

Panel radiators are made of steel and today their use has become popular in most European countries. Due to their elegance and beauty, as well as more reasonable price compared to other types.

Among the features and advantages of panel radiators, the following can be mentioned:

  • More uniformity in ambient heating than finned radiators
  • Uniform and wide radiation surface and more radiant heat compared to finned radiators (the higher the share 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
  • Seamless installation and good sealing
  • The 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.
  • In case of damage and perforation of the radiator panel, it is almost impossible to repair the panel and steel radiator in a cost-effective way. (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).

Electric Heating Radiator

Electric heating radiators have limited heat and are safe, beautiful, silent, and sometimes portable, they are also produced and supplied in all types of metal, glass, etc.

The use of electric radiators or electric heaters to provide suitable heat due to ease of operation, high safety, and noiseless operation of electric radiators is one of the most popular and favorite choices of consumers of additional heating systems in the building.

How Does an Electric Radiator Work?

An electric radiator, which is also known as an oil radiator, has the general shape of radiator grids, and inside, it is filled with oil instead of water. The elements placed in the radiator cause the oil to heat up, and its flow in the radiator fins causes the environment to heat up. The oil in this heat transfer device is permanent and does not need to be replaced 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. The heat capacity of the oil causes more energy to be absorbed in the volume compared to water.

Of course, compared to a gas heater, an electric radiator has greater safety and, of course, a higher cost of electricity consumption. For this reason, it is recommended to be used as additional heating in the bedroom and small to medium-sized rooms because gas heaters, especially the models without chimneys, should not be used in the bedroom in terms of safety.

Choosing the Right Electric Radiator

A 5 to 7-fin electric heater or radiator is 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.

A 7 to 9-fin electric heater is suitable for a room of 8 to 10 square meters with a ceiling height of about 2.8 meters in not-so-cold weather conditions.

9 to 11 fins electric radiator is suitable for a room of 10 to 12 square meters with a ceiling height of about 2.8 meters in not very cold weather conditions.

An electric heater or radiator of 11 to 13 fins is suitable for a room of 12 to 15 square meters with a ceiling height of about 2.8 meters in not very cold weather conditions.

Benefits of an Electric Heating Radiator

Electric radiators mainly have 5 to 15 fins and a power consumption of 900 to 2000 watts. In addition, 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. Glass radiators are also included in the group of electric radiators.

An 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 towel dryers.

Another advantage of electric radiators is the ability to move them using the wheels installed in the space where they are placed.

Baseboard Radiator (Baseboard Heater)

Baseboard radiators are installed at the bottom of the perimeter wall of the building instead of a regular baseboard and increase the ambient temperature in winter.

Towel Radiator (Towel Warmer/Dryer)

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 DemaTajhiz HVAC website.

Steel Heating Radiator

Unlike aluminum heating radiators, steel radiators are produced as an inseparable block. Which means you cannot add or subtract any fin to them on your own.

The width of each fin of a steel radiator is 4.5 cm, and each square meter of the surface of the steel radiator has about 440 kcal per hour of heating. But under normal conditions and a temperature difference of 60°C between the ambient air and the hot water entering the radiator.

Types of Steel Heating Radiators

The steel radiator fins are made of 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, and the number 200 represents the width, and the numbers 600, 500, and 300 are the distance from the bottom axis to the top of the steel radiator in millimeters.

The thermal surface of the 200 x 600 steel radiator is equivalent to 0.31 square meters, the thermal surface of the 200 x 500 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. Connecting the radiator fins to each other can usually be done by welding or by using the round left and right ribs (only by the manufacturer). Moreover, the width of each steel radiator fin is equal to 5.4 cm.

Due to the fact that steel radiators are made in the form of fins, they can create a good heat exchange surface in a relatively small space.

Steel Heating Radiator Capacity Estimation

For weather conditions such as the cities of Tehran, Mashhad, Isfahan, Shiraz, Rasht, Kermanshah, Mosul, Kirkuk, Erbil, Aleppo, Damascus, Kabul, etc., there is no excessive cold air penetration inside and there is only 1 of the walls is exposed to the cold outside air you can consider approximately 85 kilocalories for each square meter in the middle floors of the building, and about 95 kilocalories for each square meter at the parking lot, as well as for the units under the rooftop about 120 kcal. Moreover, for each additional wall that is in contact with the cold air outside, add about 20% more heating values.

Now you can calculate the amount of heating power needed your home or office in terms of kilocalories per hour by multiplying the square footage of the useful space by the heating kilocalories required for that space.

Finally, by dividing the required heating number produced by each fin of your chosen radiator, get the right number of radiator fins. We emphasize again that using the thermostatic valve of the radiator to adjust the indoor air temperature in winter will save about 30% of your fuel consumption.

Note: To calculate the right fin number of steel radiators required for each room in your building while considering the dimensions and the location, consult with facility engineers and experts of DamaTajhiz HVAC Group.

Steel Heating Radiator Production Process

The production process of steel radiators does not require complex technical knowledge, and its steps include common operations in metal industries, including sheet metal (cutting, pressing, and forming), welding (resistance and oxyacetylene welding), color coating, and quality control. In addition, its main consumables are ST12 steel sheets with a thickness of 1.25 mm. Also, in the stage of painting steel radiators, the choice of common gray or cream is on the manufacturer or the customer.

Choosing the Right Number of Radiator Fins

According to the dimensions of the place of installation and the calculation of 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. Also, it is better for aluminum, steel, and panel radiators to be selected by experts or installation engineers based on the type and length of the radiator, using the technical specifications table for that model.

Heating Radiator Installation & Maintenance Tips

As usual, our emphasis is on the accurate calculation of the building's thermal loads by the software and the verification of the calculation results by a facility engineer, which will definitely reduce your costs in 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).

Nowadays, due to the high fuel costs on the one hand and the phenomenon of global warming on the other hand, the use of radiator thermostatic valves instead of ordinary valves for radiators is a necessity and a completely smart and economical choice that greatly reduces the cost of fuel consumption (up to 30 percent). Also reduces your gas bills and has a noticeable effect on increasing the life of the engine room boiler. Also, pay close attention to the following points:

  • 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 are not allowed for buildings with more than 14 floors.
  • The use of the automatic venting valve facilitates the annual venting of the radiators and also reduces the risk of water leaking from the radiator to the furniture.
  • Regular and timely bleeding of the radiator is one of the most necessary principles for maintaining heating equipment, and note that basic and timely bleeding of the heating circuit system should be done carefully every year at the beginning of the cold season when the water circulation pump is turned off.
  • Another point is that when choosing the required radiator, in addition to the type, material, model, color, and price of the radiator, is to pay special attention to the dimensions of each radiator in order not to block the window above it as well as the electrical outlets installed at the height of 40 cm on the wall.

Heating Radiator Installation Location

In the winter, heat is constantly added to the room by the heating radiator, but the room temperature does not rise, and this temperature remains somewhat constant. Hence on the fact that most of the heat produced by the device is being lost through the cold walls of the building.

Heat loss occurs in two ways. One is the heat loss caused by the partitions such as the ceiling, floor, wall, window, etc., the other is the heat loss caused by the penetration of cold air through the window seams.
Although the amount of heat loss can be reduced by using double-glazed UPVC windows and a thermostatic valve on your radiator.

The height of the steel radiator (after being installed on the respective base) is 6 cm higher than the total height of each fin, so when estimating the height required for the installation of radiators, pay enough attention to this matter in order to avoid possible collision with the opening of the windows.

Buying a Heating Radiator

Buying a heating radiator requires sufficient information 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 to buy a radiator, you have undoubtedly come across dozens of different brands, each of which has its own, dimensions, color, and features, therefore different price.

On the website of DamaTajhiz HVAC, the technical information of dozens of models of heating radiators from reputed brands, along with their guarantee, has been presented for you to enjoy the good feeling of an optimal and smart purchase.

The Price of the Heating Radiators

Currently, due to the wide variety of products, making an affordable purchase is the concern to many of us.
