Stainless Steel, Electric and Flat Panel Radiators

Radiator panels have aluminum, steel, panel, and electric types, each of which is used according to its characteristics and the conditions of the relevant environment. In the following, the capacity estimation method, the selection method, and the best purchase price of all types of steel, panel, and electric radiators have been examined for wholesale purchase.

A guide to the selection & buying of steel/ panel/ electric radiators

One of the oldest methods of heating in apartments, residential, and office spaces is the use of heating radiators. It works in such a way that the heat of the radiators is distributed through heat transfer and displacement in the air.

After warming the air in the vicinity of the radiator fins, the warm air moves upwards, and the cold air replaces it. 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 panel (radiator) or in the heating central boiler of the building (engine room) is heated by equipment such as burners and is directed to different parts of the building by the pump. After that, this hot water enters the radiator and transmits its heat through displacement and radiation to the environment.

The most suitable places for installing and operating a heating radiator are places that do not require precise control of temperature and humidity, as heating radiators usually do not adjust the temperature and humidity of the environment and even reduce the relative humidity of the room. (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.

Buying an Electric Heating Radiator

1. Determination of heating power (device power)

The heating power of an electric radiator is measured in watts (W). The power of the device should be proportional to the size and volume of the space you intend to heat.

Usually, for weather conditions like Tehran and in the middle floors of the building, about 100 watts of heating power is needed per square meter. For example, for a 15-meter room, a radiator with a power of about 1500 watts is suitable.

But since electric radiators are usually used as an auxiliary or temporary heating system in spaces outside the city and especially in villas, it is better to deal with the cold air outside the city and the openness of the spaces around the villas, which leads to It gets colder inside the villa and the rooms, be careful.

2. The number of electric heating radiator blades required

The number of radiator fins is one of the most important factors in the production and uniform distribution of heat. The more the number of blades, the more surface area in contact with the air, and as a result more heat is produced. The number of electric heating radiator fins usually varies from 5 to 15 or more. A larger number is suitable for large rooms and a smaller number for small spaces.

3. Ability to adjust the temperature (thermostat) in the electric heating radiator

An adjustable temperature thermostat helps to set the temperature of the environment precisely and keep it in a desired range. This feature optimizes energy consumption and prevents overheating.

4. Energy consumption and efficiency in the electric heating radiator

Models that have an energy label with ratings of A and higher use less electricity and therefore lower your costs. Some models have an "Eco Mode" feature that automatically reduces energy consumption.

5. Safety systems in electric heating radiators

• Protection against overheating: This system automatically turns off the electric heating radiator if the temperature rises too much.

• Automatic shutdown in case of overturning: If the electric heating radiator is overturned for any reason, this system prevents the risk of fire.

• Protection against power surges: Shofaji electric radiators that have this feature automatically turn off in the event of power surges.

6. The weight and portability of the electric heating radiator

If you use the electric heating radiator in different places at home or at work, it is better to choose a device that is lightweight or has moving wheels. Some models also have a carrying handle that makes it easier to move.

7. Sound level in electric radiators

If you plan to use the radiator in places like the bedroom or study, choosing an electric heating radiator for bedrooms is a good choice. Some models have a completely silent operation or very low fan noise that does not disturb at night or in quiet environments.

8. Ability to set the timer in electric heating radiators

The adjustable timer allows you to determine the duration of operation of the electric heating radiator. For example, you can set the device to turn on at night before bed and turn off in the morning.

9. The size and design of the electric heating radiator

• The size and dimensions of the device must match the available space. If the device is to be used in a small environment, a radiator with smaller dimensions will be suitable.

• Design is also important, especially if the radiator is used in main rooms such as the living room. Some models are made with a beautiful and minimalist design, which is in better harmony with the interior decoration.

10. Warranty and reliable brand of radiators

Choosing and buying from reputable brands that have a valid warranty is one of the most important points. Well-known brands usually have better quality and performance, and provide better after-sales service in case of problems.

How to choose an electric heater or radiator

A 5 to 7-blade electric heater or radiator is suitable for a 6 to 8-square-meter room with a ceiling height of about 2.8 meters in moderate weather conditions.
A 7 to 9-blade electric heater is suitable for a room of 8 to 10 square meters with a ceiling height of about 2.8 meters in moderate weather conditions.
The 9 to 11-blade 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 11 to 13-blade electric heater or radiator is suitable for a room of 12 to 15 square meters with a ceiling height of about 2.8 meters in climates that do not have very cold winters.

The formula for calculating the heating capacity of a panel radiator

QT=[(U1*A1+...+U1*An)∗ΔT+(V*0.0749*0.24* ΔT)]*4

here:

QT heating load of each unit in kilocalories per hour
U1 to Un is 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 is 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 is 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 panel radiator in each of the rooms. Note that 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.

Steel radiator and its 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.

Types of Steel & Panel 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.

Panel 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 section radiators can create a good thermal surface in a relatively small space because they are made in the form of sections.

Advantages and Disadvantages of Panel Radiators

Panel 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.

The features and benefits of the 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 or panel radiators in humid environments compared to a variety of aluminum radiators, especially in the long run.
If the body of the panel 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.)

Choosing the Right Electric Heater

Follow the guidelines below in order to buy the most suitable electric heater for your needs (in normal weather conditions):

5 to 7-fin electric heaters are suitable for rooms of 6 to 8 square meters with a height of about 2.8 meters.
Electric heaters with 7 to 9 fins are suitable for 8 to 10 square meters of room with a height of about 2.8 meters.
9 to 11 fins electric radiators are suitable for a 10 to 12-square-meter room with a ceiling height of about 2.8 meters.
Electric radiators with 11 to 13 fins are suitable for 12 to 15 square meters rooms with a height of about 2.8 meters.

Benefits of an Electric Radiator

Electric radiators are suitable for optimal and continuous heating in small to medium-sized environments and are much safer due to the oil and element separation. Some electric radiators even have a built-in towel dryer. Another benefit of electric radiators is their ability to move on wheels for easy transportation.

Panel & Steel Radiator Selection Tips

As usual, we emphasize the accurate calculation of the building's thermal loads by the software, and the confirmation of the engineer is required. In order to buy the most suitable heating radiator that will serve you for a long time. Here are the 4 tips you best keep in mind when buying a heating radiator:

You need to install 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 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 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.

Choosing Heating Radiator Installation Location

In winter, the heating 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 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 radiator does not collide with the window above it and the length of the radiator block does not collide with the electrical outlets.
