Appearance Design
- Abroad: Some European countries such as Italy focus on the integration of their radiator designs with the overall home style, with simple and fashionable shapes, smooth lines, rich colors, and coordinated matching, which can better meet personalized needs. Like the German Kai Mei radiator, the appearance design is unique, using a front and rear dual channel series water flow organization technology, which not only improves heat dissipation performance but also has a more beautiful appearance.
Domestic: In recent years, there has been significant progress in the appearance design of radiators in China. Some brands have launched products with diverse shapes and colorful designs, but the overall style is relatively traditional and slightly inferior in matching with high-end and personalized home styles.
Material Selection
Abroad: Steel radiators are more common, such as steel column radiators and steel plate radiators in the European market, which have mature production technology and reliable quality. In addition, cast iron radiators are considered high-end luxury goods abroad and are commonly used in museums, palaces, luxury homes, and other places.
Domestic: In addition to steel radiators, copper aluminum composite radiators are also popular. They combine the good thermal conductivity and corrosion resistance of copper with the lightweight and fast heat dissipation characteristics of aluminum, making them suitable for various heating systems and occupying a relatively large market share.
Manufacturing Process
Overseas: Advanced production technology, such as high-precision welding technology and automated production lines, ensures stable product quality and high production efficiency. Like some German brand radiators, their welding process is exquisite, with uniform and firm welds, and a smooth and flat appearance.
Domestic: Manufacturing processes are constantly improving, and some large enterprises have introduced advanced equipment and technology from abroad. However, there are still some small and medium-sized enterprises with relatively backward production processes, resulting in uneven product quality.
Heat Dissipation Performance
- Abroad: Some high-end radiator products have excellent heat dissipation performance, such as Kaimei radiators, which use special technology to allow the heating water to pass through the front water channel plate first, improving radiation heat dissipation, shortening heating time, and accelerating indoor heating speed.
Domestically, the heat dissipation performance of new radiators is constantly improving. Copper aluminum composite radiators and other products have good heat dissipation effects, but there are still some products in the market that do not meet the standard for heat dissipation performance.
Applicable Water Quality
- Abroad: Some developed countries have better water quality conditions and relatively lower requirements for the corrosion resistance of radiators.
Domestically, the water quality is complex, and in some areas, the alkalinity of the water is high. Therefore, there is a high requirement for the corrosion resistance of radiators, which makes internal anti-corrosion treatment an important part of radiator production in China.
Installation Method
Abroad: The installation is relatively standardized, paying attention to details and safety. There are strict standards for the distance between radiators and walls, floors, etc., and the installation tools and accessories are relatively professional, resulting in high installation efficiency.
Domestic: There are relatively diverse installation methods, but the professional level of some installation personnel varies greatly, which may affect the installation quality and usage effect.
Testing Standards
- Abroad: The European radiator testing standard EN442 has strict requirements for the accuracy of test data, determination of steady-state conditions, as well as the size and testing conditions of the testing chamber. The accuracy requirements are higher than domestic standards.
Domestically, there are standards such as GB/T13754-92 for measuring the heat dissipation of heating radiators, but there are differences in the accuracy requirements of some parameters compared to foreign standards.
