There are many types of radiators, mainly including stainless steel, copper-aluminum composite, copper, and cast iron materials. Older houses often used cast iron, which is relatively inexpensive but has poor heat dissipation and low aesthetic appeal. Nowadays, most radiators are made of stainless steel and copper-aluminum composite materials, which have good heat dissipation, are lightweight, aesthetically pleasing, and reasonably priced. Although copper radiators perform well in all aspects, they are relatively expensive, so they are used less frequently. When it comes to radiator materials, stainless steel and copper-aluminum composite are more commonly chosen, as they better meet the aesthetic and heating needs of home decoration. It is important to pay attention to the choice of radiators, opting for panel structures whenever possible, as they dissipate heat faster and have lower water resistance compared to tubular structures.
