Shanghai Da Rui is a well-known manufacturer of radiators, with steel and copper-aluminum composite radiators being its main products. These radiators are widely used in residential heating systems across China. Today, we'll take a closer look at the features, advantages, and maintenance tips for both steel and copper-aluminum composite radiators.
**Steel Radiator**
**Maintenance Tips:**
To maintain a steel radiator properly, it's recommended to keep it filled with water. After the heating system is turned off, first close the return valve, then open the air vent to release any trapped air. Once the air is fully released, close the water valve. This helps prevent rust and extends the lifespan of the radiator.
**Advantages of Steel Radiators:**
Steel radiators are known for their fast heat dissipation and even warmth distribution. They have excellent pressure resistance and are resistant to alkali and corrosion. Their attractive design makes them a popular choice for modern homes. Additionally, they are safe, emit no radiation or pollution, and come in various styles. Steel radiators are also lightweight and can withstand high pressure, making them a reliable option for many heating systems.
**Copper-Aluminum Composite Radiator**
**Maintenance Tips:**
Copper-aluminum composite radiators are highly resistant to corrosion. Since the heat medium only comes into contact with the copper tubes, there is no risk of alkalization or oxidation. This makes them ideal for northern regions where water quality may be more challenging. Unlike steel radiators, they don’t require full-water maintenance, which simplifies the process.
**Advantages of Copper-Aluminum Composite Radiators:**
These radiators offer flexibility in terms of water pH levels, making them suitable for a wide range of heating systems. The internal copper structure provides excellent oxidation resistance, while the outer aluminum layer enhances heat dissipation. The design separates the ventilation and heat-dissipating parts, maximizing efficiency and durability.
Copper has superior thermal conductivity, allowing for quick and efficient heating. Aluminum is lightweight, easy to shape, and resistant to corrosion. This combination ensures that copper-aluminum radiators are not only durable but also energy-efficient and space-saving. Many consumers prefer them due to their long service life and resistance to corrosion.
It’s worth noting that today, the price of copper-aluminum composite radiators is comparable to that of low-carbon steel. While the internal material plays a significant role in performance, the market price of copper remains a factor to consider. Whether you choose copper or steel, it's important to evaluate your specific needs and budget before making a decision.
