Radiators have long been used for heating of apartments, offices, stores, or schools, where heat is distributed via convection (read more on electric radiators in the following).
After heating, the air surrounding the radiator rises and is replaced by colder air. This continues cycle gradually heats the whole environment.
The water in a radiator is heated in the central boiler room via boiler and burner. The hot water is then pumped to different parts of the building and exchanges its heat with the environment via radiators.
Stainless Steel,Electric and Flat Panel 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 the room (although note that nowadays a thermostatic valve on a radiator makes it possible to adjust ambient temperature).
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.
Steel radiators are manufactured as a seamless block, meaning no fins can be added or removed after manufacture. However, aluminum radiators mostly provide such an option.
The fin thickness in a steel radiator is 4.5 cm. Each square meter of the surface of a steel radiator produces about 440 kcal of heat per hour (under a normal conditions and a temperature difference of 60℃ between the ambient air and hot radiator water).
To properly determine the number of fins required for your steel radiators at each part of the building, consult with the technicians of Damatajhiz Co. by providing the dimensions and location of the desired place.

To properly determine the number of fins required for your steel radiators at each part of the building, consult with the technicians of Damatajhiz Co. by providing the dimensions and location of the desired place.
For the climate of Tehran and given no excess penetration of cold air and only a single wall exposed to the exterior cold air, the middle levels of a building approximately require 85 kcal of heat per square meter. This value is 95 kcal for the floor above the parking lot and 120 kcal for the top floors. For each additional wall in contact with cold exterior air, 20% is added to the above values.
Based on the above measures, you can estimate the heating required for each part of your building by multiplying the used area of your place with the provided unit values.
After that, you can divide the obtained heating figure by the heat generated by each radiator fin in order to determine the required fin count (the heat generated by each fin is given in the table of technical specs for the corresponding radiator model).
Again, remember that using thermostatic valves for controlling the ambient temperature in winter saves up to 30% of energy.
Production process of steel radiators : The production process does not demand advanced technical knowledge and comprises conventional metalwork operations such as plate works (cutting, pressing, forming), welding (ERW or oxy-acetylene), coating, and quality control. Steel plate is the main material used in this process. The manufacturer or client determines whether to use the common gray coating or ivory color.
Advantages and disadvantages of panel radiator : Panel radiators are mostly made of steel and are nowadays commonly used in most European countries, such that using panel radiators, supplied in steel radiator group, is increasing due to their more elegance and attractiveness and more reasonable price compared to other steel radiators.
Some of the properties and advantages of panel radiators are listed in the following :
The panel radiators also include disadvantages and weaknesses as follows :
With regard to the dimensions of the installation place and the calculation of the thermal dissipation of the desired space, you can select the number of radiator fins you need according to the shape, dimensions and heating rate of each radiator model and, in the case of panel radiators, according to the required heat, the type and length of the respective radiator panel are selected using the technical specifications table for that model.
