Key points in choosing Aluminum Radiator :

Want to use aluminum radiators to heat your home or apartment unit but you are not sure of type, capacity, brand, price, and specifications that suit your purpose? Read on to find the answers to all your questions on price, technical specifications, and the best aluminum radiators on the market.

Radiators (aluminum, electric, steel, etc.) are one of the primary means of heating in residences, offices, and commercial buildings. The radiator water is heated via the central heating system (at the mechanical room) using boilers and the heated water is pumped to various parts of the building via the pipe system, finding its way into the radiators. After exchanging its heat water flows back to the mechanical room to re-heat. This cycle iterates indefinitely.

Radiators are best to be placed in locations that do not require exact temperature and humidity adjustments, as they can only heat the environment and lack the power to adjust ambient temperature or humidity. Further, they reduce the relative humidity of a room (although, nowadays a thermostatic valve on a radiator makes it possible to adjust ambient temperature).

Aluminum Radiator

Note: the accumulation of warm air under the ceiling means using radiators is only suitable if the floor-ceiling height does not exceed 3 meters. For higher ceilings, blowing heating devices (e.g. fan coils, splits, air washers, etc.) are recommended.

Based on the manufacturing process, Aluminum Radiators come in three categories:

  1. Fully die-cast aluminum radiators
  2. Extruded aluminum radiators
  3. Die-cast extruded aluminum radiators

Advantages of Aluminum Radiator

  1. Lighter weight due to the aluminum material
  2. Durable and resistant to cracks or deformations
  3. Environment-friendly (aluminum is a recyclable metal)
  4. Higher thermal exchange efficiency compared to steel radiators
  5. Resistant against rust for long durations of time even in humid environments such as bathrooms
  6. The option to add or reduce radiator fins and accordingly, increase or reduce the heating capacity of a single radiator block (in fully die-cast or die-cast extruded types)
  7. The option to replace damaged fins (if a fin is punctured or damaged, it is possible to replace only that specific part). However, in some cases, the costs of dismantling a radiator block and replacing a fin exceed that of buying a new radiator block.

In general, aluminum radiators are lighter, more stylish, and have a higher heat transfer coefficient compared to steel radiators. However, they are also more expensive.

More about Aluminum Radiators

  • In a fully die-cast aluminum radiator, each fin is made of A413 aluminum alloy bars and has a specific heating capacity (based on the temperature difference between the feed hot water and the ambient temperature of the radiator location). The desired temperature can be obtained by selecting the appropriate number of fins.
  • Aluminum radiators have a larger contact surface with the ambient air compared to steel radiators. Moreover, they offer a better thermal conductivity due to their higher coefficient of thermal conductivity. A set of connected radiator fins is called a radiator block.
  • Under normal conditions and with a temperature difference of 60 ℃ between the ambient air and radiator feed water, each square meter of the surface of an aluminum radiator produces approximately 670 kcal of heat per hour.

To calculate the required number of radiator blades for each part of the building, please consult with experts in DamaTajhiz Co. experts by declaring the area and location of considered space.
For climates such as Tehran provided that cold air doesn’t excessively penetrate indoor and just one wall is subjected to outdoor cold air, the following amounts are considered for each square meter of building area: about 85 Kcal for middle floors, about 95 Kcal for the first floor above parking, and about 120 Kcal for floors under roof. (20% is added to the above heating values for each additional wall in contact with outdoor cold air.)
Now required heating for each part of the building can be calculated by multiplying its area by its required heating in Kcal. Finally, a number of blades are calculated by dividing the required heating number of each part to the amount of heat generated by one radiator blade.
Fully diecast radiators are produced by the highest grade production method. Each blade is manufactured on diecast mold as an integrated part and after test, finishing and painting, blades are connected to each other and packaged and offered as 5-, 7-, and 10 blades blocks. (To use radiator blocks with a different number of blades, additional blades could be added to a block on installment site.)
Aluminum Radiator
Except in extruded or profile radiators such as Alfama or Crystal radiators in which the number of their blades are fixed and cannot be reduced or increased, the number of blades can be changed in another diecast on installment place. For example, to have a 15 bladed radiator block, one 5 bladed radiator, and a 10 bladed radiator are connected to each other, or to have a 20 bladed radiator two 10 bladed radiators are connected to each other on installment time.

The production method for diecast- extruded radiators is a combination of two mentioned methods. The Upper and lower parts of each blade are produced by the diecast method and its middle part is produced by extrusion and next The upper, middle, and lower parts are connected to each other.

Selecting the installation place for radiators:

Aluminum Radiator

  • In winter, heat is transferred to the indoor space of buildings by radiators but room temperature is usually constant and doesn’t increase because a great amount of generated heat is lost.
  • Heat loss occurs in two ways. One of them is heat loss through interfaces such as wall, floor, roof, and window and the other one is the penetration of cold air through window seam. In other words, this heat loss is inevitable.
    Of course, by using double glazing UPVC windows and thermostatic valve on the radiator heat loss can be reduced but it cannot be completely eliminated.
  • In spaces with high humidity, such as a bathroom, usually, an aluminum radiator is used.
    Different types of aluminum radiators are mounted on the wall under the window and the distance between every radiator block and the floor is 10-12 cm.

Radiator selection and some points related to it:

Aluminum Radiator

  1. Considering the dimensions of the installment place and its heat loss, you can select a number of required radiator blades based on the shape, dimensions, and heat-generating capacity of each radiator model.
  2. As usual, we emphasize the precise calculation of the thermal load of the building by software and approval of calculation results by an HVAC engineer; in this case, your expenses will be reduced.
  3. Note: the normal distance between forwarding and backward warm water pipes of aluminum radiators that come out of the wall behind the radiator is 50 cm but before the selection of the radiator model it is better to recheck this distance.
    Is the distance between upper and lower pipes in your considered installment place 35, 50, or 60 cm?
  4. It is necessary to install radiators on cold borders of the building (under windows and near external walls)
  5. Considering the high cost of fuel on one hand and global warming, on the other hand, applying thermostatic valves instead of conventional valves is a must or a smart and economic choice and reduces gas bill amount considerably and also has an appreciable effect on mechanical room and heating package lifetime.
  6. Installing an automatic bleeding valve facilitates bleeding and reduces water leakage to furniture and appliances.
  7. Regular and on-time bleeding is one of the most important principles of the maintenance of heating equipment. Please note that bleeding should be done carefully every year at the beginning of the cold season while the water circulating pump of the radiator is turned off.
  8. In a time of selecting aluminum radiators, please select a model that in addition to having proper sealing and shape, has similar products in the market so that if in future you need to buy a number of blades, you can find them easily and with low cost.
  9. The more is blade width, the more stylish and beautiful the is the radiator. The usually bladed aluminum radiator is provided in two widths: 6 and 8 cm. so it is better to use blades with 8 cm width.
  10. Please note that the minimum distance between the radiator block and the wall (5 cm) and floor (10 cm) be observed because not observing these distances results in a significant hearing loss.
  11. As much as possible there should be nothing around radiators so that air circulates better and the efficiency and thermal capacity of the radiator are increased. Try to put all kinds of coverings and obstacles (such as curtain, furniture…) far from the radiator.
  12. Providing towel warmer radiators in spaces such as bathroom and toilet in addition to reducing humidity and increasing health factors in them, is good for drying damp towels and clothes. Additionally, by decorative designs available in the market you can create a beautiful display in such places.

Some advantages of bleeding of the heating circuit include:

  • bleeding reduces the risk of water leakage from the system (radiators)
  • bleeding results in longer life of all equipment including boiler, pump, radiator, package….
  • Bleeding increases the heating efficiency of the system and especially that of radiator blocks significantly and finally reduces gas expenses.
