Radiators are essential for maintaining a warm and comfortable atmosphere in our homes. They enhance the overall beauty of our living areas in addition to being functional. Aluminum and bimetallic radiators are notable for their longevity and efficiency among the different types of radiators that are available. Anyone thinking about replacing or installing heating systems in their homes needs to be aware of the typical dimensions of these systems.
Because of their superior heat conduction qualities and lightweight design, aluminum radiators have become more and more popular. These radiators are available in different sizes to suit a range of room sizes and heating requirements. Aluminum radiators are a great option for modern homes where space is often limited because they are generally smaller and slimmer than traditional cast iron radiators.
Bimetallic radiators, on the other hand, combine the benefits of steel and aluminum to provide better heat retention and durability. These radiators offer a strong heating solution that is impervious to damage and corrosion because their aluminum cores are protected by steel panels. Bimetallic radiators, like aluminum radiators, are available in a variety of sizes to accommodate different heating needs.
Comprehending the standard measurements of aluminum and bimetallic radiators is essential to guaranteeing maximum heating efficiency and effective utilization of available space in your residence. Radiators that are the right size for your rooms will ensure even heating throughout and reduce energy use. Choosing the proper radiator dimensions is crucial for creating a cozy and energy-efficient living space, whether you’re building a new home or remodeling an old one.
It’s critical to comprehend the standard dimensions of aluminum and bimetallic radiators in order to assess the insulation and heating requirements for your house. The efficacy and efficiency of your heating system are greatly influenced by these dimensions. Due to their lightweight design and quick heat transfer, aluminum radiators are a great choice for contemporary homes with constrained space. Bimetallic radiators, on the other hand, combine the advantages of both materials: steel interiors for durability and aluminum exteriors for rapid heat distribution. Homeowners can ensure maximum warmth and comfort throughout their homes by making educated decisions about their heating systems based on the dimensions of these radiators.
What is the center distance of a radiator
Occasionally, the aluminum or bimetallic radiator heating that was chosen based on heat output is too long and too tall to fit beneath the window. Furthermore, it’s imperative to keep the heaters at the recommended distances from the wall, window sill, and floor in addition to fitting them into the existing opening.
If not, there won’t be as much space for convection airflow, which will lower the heating efficiency. The product’s installation diagram shows the values for these distances:
You must be aware of the necessary heat output as well as the size of the window recess (if one) in order to determine the height and length of the heater beforehand. Furthermore, it should be recognized that the center-to-center distance is the single, universal size for all bimetallic and aluminum heating radiators. This is the space between the two axes that run the length of the battery’s horizontal collectors. The figure makes it evident how this idea varies from other heater dimensions:
As a point of reference. This pattern works with any kind of metal radiator.
Heating device center-to-center spacing is 350 and 500 mm, and it is upheld by every manufacturer without exception. It is possible to produce additional models with 200, 600, 700, 800, or 900 mm axis spacing. Although the values of other dimensions may vary, they typically fall within these ranges:
- section length (visually – width) from 80 to 88 mm;
- depth – from 52 to 100 mm;
- full (mounting) height of the product at the center distance of 500 mm – from 570 to 590 mm.
Note: It is pointless to list mounting height values for products with different intervals here since they can be found on the website of the relevant manufacturer.
How to choose the size of the radiator
The following is the battery selection based on size. Once the appropriate depth and height of the manufacturer’s products have been confirmed, it is time to determine how many sections each room will need. In order to do this, we use the following algorithm to determine the necessary heat output of the heating devices:
- in a room with one exterior wall and 1 window, 100 W of heat per 1 m2 of floor area is assumed;
- if there are two walls facing the outside, it is necessary to take 120 W per 1 m2 of the room;
- when there are 2 walls and 2 windows, then 130 W/m2.
Note: Rooms up to 2.5–2.7 м in height will yield the correct result according to the algorithm. It is advised to use 40 W of heat per 1 m3 of room volume if the ceiling is higher.
We obtain the necessary heat output by multiplying these numbers by the area of the rooms. Using the heat output of one section as a base, we will then calculate the size of the battery. Tables detailing all of the dimensions, spacing, and heat output of GLOBAL aluminum and bimetallic radiators are provided below, for instance:
Generally, when speculating the heat output of a section, it is taken into consideration that the average temperature differential between the coolant and the room air is 70 ˚C (noted in the passport as at DT = 70). This indicates that the supply water temperature in a room should be approximately 100 ˚C at +22 ˚C, but it is rarely 70 ˚C in a private residence.
Additionally, it should be noted that the battery section will produce 30% less heat at this temperature.
Advice: To avoid making a mistake, deduct 30%, or better yet, 50%, from the power indicated on the product’s passport.
Finding their number is simple once the real power of one section is ascertained: just divide the previously determined heat flow rate by this amount. However, as seen in the picture, you can then run into a situation where the heater assembly either cannot fit into the window sill niche or, conversely, appears too unrepresentative there:
How to choose the size of batteries in such cases? If it does not fit under the window, the solution is simple: divide the number of sections into 2 parts, instead of one device you will get two. The length of the first one will be 75% of the window opening, and the second one will be all that"s left. This part can be placed near the side wall, bringing pipelines to it. In the reverse situation (as in the photo), you need to take sections with a smaller center distance and height. Their heat output is less, which means that the total length of the heater after recalculation will increase, and as a result it will look great.
| Type of Radiator | Typical Dimensions |
| Aluminum Radiator | Height: 400-900 mm; Width: 400-2400 mm |
| Bimetallic Radiator | Height: 300-900 mm; Width: 400-3000 mm |
Selecting the appropriate radiators for your house is essential to keeping your heating system functional and comfortable. Radiators made of aluminum and bimetallic materials are two common choices, each with unique benefits and features. To make an informed choice, you must be aware of the typical dimensions of these radiators.
Aluminum radiators are renowned for their rapid heat transfer capabilities and lightweight design. These radiators typically come in a variety of sizes, with heights between 300 and 900 mm and lengths between 400 and 3000 mm. Their efficient heating performance guarantees warmth even in larger spaces, and their sleek and modern design makes them appropriate for modern homes.
Bimetallic radiators, on the other hand, combine the advantages of steel and aluminum to provide robustness and effective heat distribution. These radiators typically have lengths ranging from 400mm to 3000mm and heights between 300mm and 900mm, which is comparable to the size variations of aluminum radiators. Bimetallic radiators are perfect for both residential and commercial settings because of their strong construction and superior heat retention capabilities.
The size of the rooms, the amount of insulation in each, and your heating needs should all be taken into account when choosing the radiators’ dimensions. Greater heat output radiators might be needed in larger rooms, while smaller units with fine temperature control might work better in well-insulated areas. You can maximize comfort and energy efficiency throughout your house by matching the radiator dimensions to your unique requirements.
In conclusion, choosing the best heating solution for your home requires an understanding of the typical dimensions of bimetallic and aluminum radiators. There are options available to suit your preferences, regardless of whether you prioritize long-term durability or rapid heat transfer. You can make an informed choice that improves the comfort and effectiveness of your heating system by taking into account variables like room size and insulation levels.
